Mitral valve prolapse.

Mitral valve prolapse is a common mitral valve disorder manifested clinically as a midsystolic click and/or a late systolic murmur (the click-murmur syndrome) and pathologically as billowing or prolapsing mitral leaflets (the floppy valve syndrome). Not only is it one of the two most common congenital heart diseases and the most common valve disorder diagnosed in the United States, but it is also prevalent throughout the world. Mitral valve prolapse may be associated with a variety of other conditions or diseases. Diagnosis of mitral valve prolapse should be made on clinical grounds and, if necessary, supported by echocardiography. The majority of patients with mitral valve prolapse suffer no serious sequelae. However, major complications such as disabling angina-like chest pains, progressive mitral regurgitation, infective endocarditis, thromboembolism, serious arrhythmias, and sudden death may occur. Unless these serious complications occur, most of the patients with mitral valve prolapse need no treatment other than reassurance, including those with atypical chest pain or palpitation unconfirmed by objective data. Therapy with a beta-blocker for disabling chest pain and/or arrhythmias and antiplatelet therapy for cerebral embolic events may be indicated. In occasional patients with significant mitral regurgitation surgery may be necessary.

Panic attacks in families of patients with mitral valve prolapse.

One explanation for the association between mitral valve prolapse (MVP) and panic attacks in clinic populations is that panic attacks represent a set of symptoms caused by mitral prolapse. Since mitral prolapse is often familial, this hypothesis predicts a higher incidence of panic attacks in relatives of persons with prolapse than the general population and the incidence of panic attacks in the relatives should be independent of panic attacks in the proband. We interviewed 50 probands with mitral prolapse and obtained family history data on panic attacks in their first degree relatives. The incidence of panic attacks in these relatives was 4.5 +/- 1.4% which is consistent with control rates which we have reported in previous studies. Twelve MVP probands also had panic attacks. The incidence of panic attacks in their relatives (15.7 +/- 5.1%) was significantly higher than the rate found among relatives of 38 probands without panic attacks (1.2 +/- 0.8%). These findings are consistent with the hypothesis that mitral prolapse and panic attacks are segregating independently in these families.

Prevalence of mitral valve prolapse in healthy Saudi women.

Two-hundred-and-thirty-two Saudi young women were prospectively clinically examined for the presence of mitral valve prolapse. Phonocardiograms recorded in all subjects at rest in supine position revealed 10.7% incidence of systolic clicks and/or mid to late systolic murmurs. Echocardiographic studies were performed in supine, left lateral as well as sitting up positions. Twenty-eight subjects were found to have mitral valve prolapse. Of these, 21 subjects had mid to late systolic prolapse when the other seven subjects were found to have pansystolic prolapse (holosystolic). Eight of the 28 positive subjects had auscultatory evidence of mitral valve prolapse. It seems that mitral valve prolapse is more common than expected in healthy Saudi women population.

Magnetic resonance imaging of the levator ani in the squirrel monkey: a comparison of muscle volume between a cohort with pelvic organ prolapse and matched normals.

OBJECTIVE: Magnetic resonance imaging was used to test whether squirrel monkeys with pelvic organ prolapse have reduced pelvic muscle volumes, compared with matched normals. STUDY DESIGN: Levator ani and obturator internus volumes obtained from T1-weighted axial scans of matched groups were measured. Muscle volumes and weights were compared for animals necropsied after magnetic resonance imaging. RESULTS: Two observers concurred on measures of levator ani and obturator internus (Kendal tau > or = 0.60 with P < .003). Levator ani volume was related to mass (R2 = 0.62, P = .0009). Animals with pelvic organ prolapse did not differ (P = .67, Wilks multivariate test) from those without pelvic organ prolapse in age, parity, and weight. Levator ani differed between groups (pelvic organ prolapse = 520 mm3 versus normals = 392 mm3, P = .015) and not sides (P = .80). The obturator internus did not differ between groups (P = .29) or sides (P = .72). CONCLUSION: Magnetic resonance imaging demonstrates that levator ani volumes in parous squirrel monkeys with pelvic organ prolapse were not reduced, suggesting that prolapse is not related to pelvic muscle size reduction in this species.

Bowel symptoms in women planning surgery for pelvic organ prolapse.

OBJECTIVE: The objective of the study was to measure associations between bowel symptoms and prolapse. STUDY DESIGN: Baseline data were analyzed from 322 women in the Colpopexy And Urinary Reduction Efforts trial of sacrocolpopexy with or without Burch colposuspension. Women completed the Colorectal-Anal Distress Inventory and Colorectal-Anal Impact Questionnaire and underwent Pelvic Organ Prolapse Quantification. Associations between symptoms and questionnaire scores and Pelvic Organ Prolapse Quantification measures were assessed. RESULTS: Mean age was 61 +/- 10 years. Pelvic Organ Prolapse Quantification stages were II (14%), III (67%), and IV (19%). Colorectal-Anal Distress Inventory symptoms did not increase with prolapse stage. Colorectal-Anal Distress Inventory obstructive subscale scores were higher in stage II women (median 29 [interquartile range 8,92] versus 17 [0,33] and 25 [0,38] for stages III and IV, respectively; adjusted P = .01). The few statistically significant correlations between symptoms and vaginal descent were negative and weak (less than 0.2). CONCLUSION: Bowel symptoms and questionnaire scores do not increase with prolapse stage in women presenting for sacrocolpopexy.

Aortic valve prolapse associated with outlet-type ventricular septal defect.

BACKGROUND: Aortic valve prolapse is frequently associated with juxta-arterial ventricular septal defect. The significance of its association with other outlet types of ventricular septal defect, however, remains unclear. METHODS: From 1987 to 2002, 677 patients (male:female ratio, 424:253) who received surgical repair for ventricular septal defect extending to the outlet septum were reviewed. Based on surgical findings, ventricular septal defects were classified as juxta-arterial, perimembranous outlet, or muscular outlet type. RESULTS: Aortic valve prolapse occurred in 373 of 677 patients (57.2%) with 209 juxta-arterial, 103 perimembranous outlet, and 61 muscular outlet type. Significant aortic regurgitation developed in 51 of 373 (14%). Among 252 patients with regular follow-up, the mean onset ages of aortic valve prolapse in juxta-arterial, perimembranous outlet, and muscular outlet type were 4.9, 5.0, and 5.1 years, respectively (no statistical difference). The presence of larger shunt and probably anterior malalignment predicted an earlier onset of aortic valve prolapse. Perimembranous outlet and muscular outlet type ventricular septal defect were frequently associated with infundibular hypertrophy and subaortic ridge, and perimembranous outlet type was associated with anterior septal malalignment. In juxta-arterial ventricular septal defect and ventricular septal defect with anterior malalignment, prolapsed cusp was always the right coronary cusp, but noncoronary cusp involvement was also common in perimembranous outlet type (17 of 103, 16.5%). CONCLUSIONS: The association with anterior septal malalignment, infundibular stenosis and subaortic ridge is related to the location of the outlet ventricular septal defect. The age of onset of aortic valve prolapse in each type was quite similar, and a larger shunt may predict an earlier onset.

Vaginal vault prolapse: choice of operation.

The surgeon who faces a patient with vaginal vault prolapse is dealing with a complex and intriguing challenge. Part of the complexity is due to the lack of standardization and routine application of tools to assess pre- and postoperative anatomical and functional outcomes. Patient satisfaction is a major endpoint for surgical success; thus all aspects of the prolapse pathology and the patient's lifestyle should be considered. The surgeon needs to be well versed and flexible in order to choose the most appropriate operative approach to achieve optimal results for an individual patient. In this chapter we present the vaginal and abdominal approaches for the correction of vaginal vault prolapse, with discussion of the surgical outcomes and complications for each technique. A comprehensive comparison of the various techniques is offered on the basis of current published literature. In addition, we focus on various controversies, including the prevention of vault prolapse at the time of hysterectomy, issues regarding uterine preservation, the management of overt or occult concomitant stress incontinence, and the place-if any-for combined anti-incontinence procedures at the time of prolapse surgery. New minimally invasive techniques for vault prolapse are also reviewed. We emphasize areas that call for further research and for standardized outcome criteria.

Ischemic mitral valve prolapse: mechanisms and implications for valve repair.

OBJECTIVE: The aim of this study was to assess the mechanisms of prolapse in ischemic mitral valve regurgitation (MR) and the techniques of valve repair. METHODS: Out of 121 patients operated upon for ischemic MR, a prolapse was present in 44 patients (36.4%). The operation was performed emergently in four cases (9.1%) and electively in 40 patients (90.9%). Fifteen patients (34.1%) were operated upon within 60 days following acute myocardial infarction. RESULTS: The diagnosis of prolapse had been overlooked by echography in five cases (11.4%). A commissural area was involved as the site of prolapse in 31 cases (70.4%). The mechanism of prolapse was a papillary muscle (PM) lesion in 38 cases (86.4%) (anterior PM: n=8, posterior PM n=36) or a chordal lesion in six cases (13.6%). PM injury was elongation (n=16), or rupture (total n=1, partial n=21, incomplete n=4). The operative technique was mitral valve repair with Carpentier's techniques in 42 cases (95.5%) or replacement in two cases (4.5%). Hospital mortality was 11.4% (n=4). The mean follow-up was to 44.7+/-29.6 months. Overall survival and freedom from reoperation were 68.3+/-9.0 and 89.9+/-5.7% at 5 years, respectively. Freedom from MR equal or > grade 2 was 69.7+/-9.5% at 5 years. CONCLUSIONS: The mechanisms of ischemic mitral valve prolapse were variable and tightly linked to the PM anatomy. A reliable mitral valve repair could be achieved in most cases with acceptable mid-term results.

Treatment of genital prolapse by hammock using porcine skin collagen implant (Pelvicol).

INTRODUCTION: To assess the feasibility and efficacy of the hammock using a porcine skin collagen (Pelvicol) implant for the treatment of genital prolapse by the vaginal route. A total of 47 women with Stage III or IV genital prolapse underwent surgical treatment with porcine skin collagen implantation using anterior transobturator and posterior bilateral sacrospinous fixations. Genital prolapse treatment was combined with hysterectomy in 34 patients (72%). TECHNICAL CONSIDERATIONS: Porcine skin collagen implantation was feasible in every case. The surgical procedure lasted a median of 90 minutes (range 80 to 150). No vessel injuries, one bladder injury, and one rectal injury not requiring additional surgery occurred. One pararectal hematoma required a second procedure. The median follow-up was 24.6 +/- 8.5 months (range 6 to 42). No rejection of the porcine grafts occurred. Of the 47 women, 39 (83%) had optimal anatomic results, 5 had asymptomatic Stage I prolapse, and 2 had Stage II prolapse. The subjective cure rate was 93.6% (44 of 47 patients). The postoperative scores for lifestyle and urinary discomfort improved significantly after the procedure (P < 0.0001 and P < 0.0002, respectively). Of the 18 patients who were sexually active, an improvement in sexual discomfort occurred (P = 0.04). CONCLUSIONS: These short-term results suggest that hammock using porcine skin collagen implantation by the transobturator route and bilateral sacrospinous fixation is a safe and effective treatment for genital prolapse.

Relationship between severity of mitral regurgitation and prognosis of mitral valve prolapse: echocardiographic follow-up study.

We investigated the relation between the severity of mitral regurgitation and the development of complications and cardiac events by using two-dimensional and color Doppler echocardiography in 229 consecutive patients with mitral valve prolapse. The frequency of moderate and severe mitral regurgitation was significantly higher in patients with a prolapsed posterior leaflet (61%) than in patients with a prolapsed anterior leaflet (25%), and the older the patient, the greater the severity of mitral regurgitation. The occurrence of complications, such as atrial fibrillation, congestive heart failure, and chordal rupture, was significantly greater in prolapsed posterior leaflet cases than in prolapsed anterior leaflet cases, and the occurrence was closely associated with the degree of severity of mitral regurgitation. Multiple logistic regression analysis showed that the severity of mitral regurgitation is a strong prognostic indicator for developing complications. Furthermore in a subgroup of 49 patients tracked for a mean of 4.8 years, the new development of complications was significantly higher in patients who showed a progression in the severity of mitral regurgitation (52%) that in patients without progression in severity (8%). The initial severity of mitral regurgitation was related to the occurrence of cardiac events (mitral valve replacement, infective endocarditis, cerebral embolism and death). The data indicated that the progression of mitral regurgitation is closely associated with the development of complications and cardiac events and suggest that the severity of mitral regurgitation is an important prognostic indicator for the development of complications and cardiac events in patients with mitral valve prolapse.

Fibromuscular dysplasia of small coronary arteries and fibrosis in the basilar ventricular septum in mitral valve prolapse.

The mechanism of sudden cardiac death in patients with mitral valve prolapse is poorly understood. Twenty-four hearts from patients with mitral valve prolapse who suddenly died (mean age 34 +/- 8 years) and 16 trauma control hearts (mean age 30 +/- 7 years) were histologically studied. Dysplasia of the atrioventricular nodal artery was present in 18 of 24 hearts with mitral valve prolapse and four of 16 controls hearts (p = 0.003). The degree of luminal narrowing, as morphometrically measured, was significantly greater in hearts with mitral valve prolapse (p = 0.003). The degree of fibrosis in the base of the ventricular septum, as calculated by computerized morphometry, was greater in hearts with mitral valve prolapse (p = 0.0002) and independent of age, sex, and heart weight (p = 0.005). We conclude that arterial dysplasia in mitral valve prolapse may contribute to sudden cardiac death mediated by ventricular fibrosis.

Evaluation of mitral valve prolapse by four-dimensional echocardiography.

To observe the stereoscopic structure and the motion of the prolapsing mitral valve and its regurgitant jet in comparison with the normal mitral valve, four-dimensional (or dynamic three-dimensional) echocardiography of mitral valve apparatus was obtained in 20 patients with mitral valve prolapse and 10 unaffected subjects by use of transthoracic and transesophageal methods. The normal mitral valve apparatus has a consistent saddle-shaped configuration, with its anterior and posterior high points located near the aortic root and posterior left ventricular wall, respectively, and its low points located medially and laterally. In mitral valve prolapse, the spatial relation of mitral leaflets and anulus can be observed in four dimensions either from the left ventricle toward the left atrium or from the left atrium toward the left ventricle; the position, size, shape, motion, and extent of functional abnormality of the prolapsing mitral valve were clearly displayed. On the long-axis view of the left ventricle and the apical four-chamber view of four-dimensional echocardiography, the part of prolapsing mitral valve that protruded into the left atrium appeared as a spoon-like depression. We also obtained four-dimensional images of regurgitant blood flow to observe the stereoscopic view of blood flow column and its cross-sectional area, spatial position, and dynamic changes. This technique is of great value in evaluating patients with mitral valve prolapse, increasing the diagnostic sensitivity and specificity, and giving assistance to the surgeons in making preoperative therapeutic decisions and assessing the intraoperative and postoperative results.

Randomized prospective comparison of needle colposuspension versus endopelvic fascia plication for potential stress incontinence prophylaxis in women undergoing vaginal reconstruction for stage III or IV pelvic organ prolapse. The Continence Program for Women Research Group.

OBJECTIVE: Severe prolapse may mask potential genuine stress urinary incontinence in women. Some have suggested that a suspending urethropexy be performed in women who have potential genuine stress incontinence demonstrated by barrier reduction of the prolapse preoperatively. Our aim was to compare outcomes after prolapse surgery that included a formal bladder neck suspension with those operations that did not. STUDY DESIGN: This prospective randomized clinical trial assigned 32 women with bladder neck hypermobility and stage III or IV pelvic organ prolapse to receive either a needle colposuspension or bladder neck endopelvic fascia plication as part of the vaginal reconstructive surgery. Twenty-nine subjects underwent detailed clinical, anatomic, urodynamic, and quality-of-life evaluations before and 6 weeks and 6 months after surgery; 23 completed urinary diary and quality-of-life evaluations after a mean of 2.9 years. RESULTS: Needle colposuspension increased short-term complications without providing additional protection from de novo stress incontinence. Barrier testing before surgery predicted urethral sphincteric resistance after surgery; however, such testing neither predicted a patient's function after surgery nor indicated the need for a suspending urethropexy. The combination of a needle colposuspension with a sacrospinous ligament suspension predisposed to the early development of support defects of the upper anterior vaginal segment and to failure of bladder neck support. CONCLUSIONS: Preoperative barrier testing in women with severe prolapse is not useful in identifying individuals who require a suspending urethropexy. Needle colposuspension increases short-term complications, lacks durability, and may predispose to early and severe recurrent anterior prolapse when performed with a sacrospinous ligament vault suspension.

Uterosacral ligament fixation for vaginal vault suspension in uterine and vaginal vault prolapse.

OBJECTIVE: The purpose of this study was to determine the simplicity, safety, anatomic, and functional success of using the uterosacral ligaments for correction of significant complex uterine and vaginal vault prolapse by the vaginal route. STUDY DESIGN: Fifty women with uterine or vaginal vault prolapse with descent of the cervix or the vaginal vault to the introitus or greater were treated between 1993 and 1996 by the same surgeon with bilateral uterosacral ligament fixation to the vaginal cuff by the vaginal route. Included were patients with significant enterocele, cystourethrocele, rectocele, and stress urinary incontinence who had concomitant repair of coexisting pelvic support defects. An etiology of vaginal vault prolapse is discussed. RESULTS: Uterosacral ligaments were identified and used for successful vaginal vault suspension by the vaginal route in all 50 consecutive patients without subsequent failure or significant complications with a maximum follow-up of 4 years. One patient had recurrent stress urinary incontinence and two had asymptomatic cystoceles. Three patients had erosion of monofilament sutures at the vaginal apex. CONCLUSIONS: In these 50 patients with significant complex uterine or vaginal vault prolapse, uterosacral ligaments could always be identified and safely used for vaginal vault suspension by the vaginal route with no persistence or recurrence of vaginal vault prolapse 6 to 48 months after surgery. Excessive tension by the surgeon on tagged uterosacral ligaments at the time of hysterectomy may be an etiologic factor in vaginal vault prolapse.

Sacrospinous ligament fixation and modified McCall culdoplasty during vaginal hysterectomy for advanced uterovaginal prolapse.

OBJECTIVE: Our purpose was to compare anatomic and functional results of 2 procedures performed at vaginal hysterectomy for vaginal vault suspension in patients with advanced uterovaginal prolapse. STUDY DESIGN: A retrospective case-control study was designed comparing 62 patients who underwent sacrospinous ligament fixation and 62 members of a matched control group who underwent modified McCall culdoplasty during vaginal hysterectomy and reconstructive pelvic surgery. The 62 pairs were matched for grade of uterine prolapse, age, parity, dystocia, menopause, body mass index, previous prolapse surgery, heavy work, constipation, and chronic cough. RESULTS: Operative time and blood loss were significantly greater (P < .001) in the group with sacrospinous suspension. With a follow-up from 4 to 9 years, 17 (27%) patients receiving sacrospinous suspension had prolapse recurrence at any vaginal site compared with 9 (15%) patients receiving modified McCall culdoplasty (P = .14). Recurrent vault prolapse was recorded in 5 (8%) and 3 (5%) subjects, respectively (P = .72). Thirteen (21%) and 4 (6%) patients, respectively, had recurrent cystocele (matched odds ratio 4.1, 95% confidence interval 1.3 to 14.2, P = .04). No significative difference was observed in postoperative sexual function. CONCLUSION: Sacrospinous ligament fixation is not recommended as a prophylactic measure at vaginal hysterectomy in patients with uterovaginal prolapse.

A comparison of women with primary and recurrent pelvic prolapse.

OBJECTIVE: Our purpose was to identify clinically relevant differences in women with primary and recurrent pelvic organ prolapse. STUDY DESIGN: Consecutive women undergoing reconstructive surgery completed a urogynecologic history and physical examination and underwent either multichannel urodynamic testing or pelvic floor fluoroscopy, or both. Two groups were compared: primary (no prior surgery for pelvic organ prolapse) and recurrent. RESULTS: One hundred eighty-one consecutive women were studied-103 with primary and 78 with recurrent prolapse. The groups were similar with respect to age, race, weight, vaginal parity, prolapse stage, urodynamic diagnosis, extent of visceral malposition, and common urinary, anorectal, and sexual symptoms. Clinically relevant differences were found, with the recurrent group having shorter vaginal lengths (P =. 0005), being more likely to have had a hysterectomy for a nonprolapse indication (P =.00018) and to be receiving hormone replacement therapy (P =.00003). CONCLUSION: The women with primary and recurrent pelvic organ prolapse in this population were remarkably similar in many quantifiable parameters measured. The clinical differences may be related to previous surgery for pelvic organ prolapse.

Signs of genital prolapse in a Swedish population of women 20 to 59 years of age and possible related factors.

OBJECTIVE: Our objective was to study the prevalence of genital prolapse and possible related factors in a general population of women 20 to 59 years of age. STUDY DESIGN: Of 641 eligible women in a primary health care district, 487 (76%) answered a questionnaire and accepted an invitation to a gynecologic health examination. RESULTS: The prevalence of any degree of prolapse was 30.8%. Only 2% of all women had a prolapse that reached the introitus. In a set of multivariate analyses, age (P <.0001), parity (P <.0001), and pelvic floor muscle strength (P <.01)-and among parous women, the maximum birth weight (P <.01)-were significantly and independently associated with presence of prolapse, whereas the woman's weight and sustained hysterectomy were not. CONCLUSIONS: Signs of genital prolapse are frequently found in the female general population but are seldom symptomatic. Of factors associated with genital prolapse found in this study, pelvic floor muscle strength appears to be the only one that could be affected.

Magnetic resonance imaging measurements of extraocular muscle path shift and posterior eyeball prolapse from the muscle cone in acquired esotropia with high myopia.

PURPOSE: To investigate extraocular muscle (EOM) path shift and prolapse of posterior eyeball from muscle cone in acquired esotropia with high myopia (AEHM), using magnetic resonance imaging. DESIGN: A case-control study. METHODS: There were 16 eyes with AEHM, 11 with high myopia (HM), 12 with moderate myopia (MM), and 11 control eyes. Extraocular muscle shift was evaluated by measuring angles formed by the line connecting orbital centroids and the line connecting each orbital centroid and each EOM centroid. The ratio of the prolapse in the posterior eyeball from the muscle cone was also measured. RESULTS: Both inferior shift of lateral rectus (LR) and nasal shift of superior rectus (SR) muscle were observed in the AEHM group, compared with HM, MM, and control groups. Neither shifted significantly in the HM group compared with control group. The prolapse ratio in AEHM group was higher than in the HM, MM, and control groups. Greater EOM shifts and eyeball prolapse were observed when the AEHM was more severe, as in esotropia fixus. CONCLUSIONS: In AEHM, a prolapsing eyeball shifts LR inferiorly and SR nasally; these findings were not observed in high myopia with neither ocular deviation nor restriction. These shifts reduce abduction and supraduction and increase infraduction and adduction in AEHM. The shifts would be predicted to create a hypoesodeviation, which is a common finding in AEHM. Both EOM shifts and superotemporal eyeball prolapse tend to be greater in esotropia fixus.
