Cardiac surgery in patients with human immunodeficiency virus infection: indications and results.

Ten patients with human immunodeficiency virus (HIV) infections underwent cardiac surgery using cardiopulmonary bypass. All were in Centers for Disease Control (CDC) group II. The cardiac involvement was either urgent or severely symptomatic in all cases. One patient died due to acquired immunodeficiency syndrome (AIDS) unrelated cause. No complications were encountered in this series. Eight of the nine survivors were available for follow-up. Three of these eight patients progressed to AIDS (CDC group IV) and subsequently died. Five patients are alive and in CDC group II. Prognosis of the HIV infection and the natural history of the cardiac disease are the two main elements to be considered whenever cardiac surgery is required.

[Mycotic aneurysm of the carotid artery secondary to acute bacterial endocarditis].

Mycotic aneurysms of the extracranial carotid arteries are rare. A new case of mycotic aneurysm of the bifurcation of the carotid artery secondary to acute bacterial endocarditis affecting the aortic valve is reported. Simultaneous treatment of the two lesions was instituted. The twenty six cases of mycotic aneurysm of the extracranial carotid arteries previously described in the literature are reviewed by the authors.

Mitral valve repair using Carpentier techniques in patients more than 70 years old. Early and late results.

BACKGROUND: Mitral valve incompetence in elderly patients raises the problem of whether to replace or to repair the mitral valve. The purpose of this study is to review our experience with mitral valve repair in patients > 70 years old. METHODS AND RESULTS: Between 1986 and 1991, 79 consecutive patients > 70 years old underwent mitral valve repair by Carpentier techniques. The most frequent cause was degenerative valve disease (65 of 79). Preoperative echocardiography showed that 6% of the patients had type I, 88% type II, and 5% type III mitral valve dysfunction. Anatomic lesions encountered at surgery confirmed the preoperative echocardiographic findings, with 88% of the patients with a leaflet prolapse either of the posterior leaflet (56%) or of both the anterior and posterior leaflets (32%). Multiple surgical procedures were required in each patient. Posterior leaflet resection was the most common technique used (76%). Prosthetic ring annuloplasty was used in 96% of patients. Associated procedures were performed in 21.5% of cases. Three patients died, for an operative mortality of 3.8%. One patient (1.3%) required reoperation for residual mitral insufficiency. Nonfatal complications related to the patients' preoperative condition were noted in more than half of the patients. Echocardiography obtained before discharge revealed absent or minimal mitral insufficiency in 91% of patients and mild mitral insufficiency (2+/4+) in 9%. Follow-up was available for 74 of 76 patients (97.3%) and ranged from 3 months to 6 years (mean, 22 months). Two patients (2.6%) were lost to follow-up. Sixty patients (89%) were in New York Heart Association functional class I or II. Seven patients died and one required reoperation. Actuarial analysis of the results showed overall survival at 5 years 81 +/- 11%; freedom from thromboembolism, hemorrhage, and reoperation 97 +/- 5%, 97 +/- 5%, and 98 +/- 4%, respectively. Color-coded echo Doppler studies obtained in 67 patients at the time of follow-up showed absent or minimal MI (91%) (n = 61), and mild MI in 9% (n = 6). CONCLUSIONS: These data suggest that mitral valve repair using Carpentier techniques should now be considered as the procedure of choice in patients of any age referred for mitral insufficiency.

[Heart surgery and human immunodeficiency virus].

The authors report their experience of cardiac surgery in 9 carriers of the human immunodeficiency virus (HIV). Eight HIV seropositive patients underwent surgery under cardiopulmonary bypass for valve repair or replacement. Eight patients were asymptomatic with respect to their viral infection: one patient had generalised lymphadenopathy. The hospital mortality was 1/9 (11.1%). There was no infectious morbidity. Five patients are alive with an average follow-up of 29.6 months and in NYHA Stages I or II. One patient deteriorated and presented symptoms of an AIDS-related complex. These results suggest that if the operative indications are justified, cardiac surgery under cardiopulmonary bypass may be performed in asymptomatic HIV seropositive patients.

Comparative anatomy and histology of the radial artery and the internal thoracic artery. Implication for coronary artery bypass.

Anatomical characteristics of the radial a. were compared to those of the internal thoracic a., considered as a gold standard in coronary surgery. The length, the diameter, the collateral distribution and the wall thickness of these two arteries were studied comparatively. In addition, a comparative histological analysis was carried out. Anatomical and histological characteristics of these two arteries have important implications for coronary artery bypass.

Tricuspid valve myxoma: a rare indication for tricuspid valve repair.

Excision of a myxoma involving the tricuspid valve often necessitates tricuspid valve replacement or a less than optimal margin of resection. We report a successful tricuspid valve repair after en bloc resection of a myxoma involving the septal leaflet of the tricuspid valve.

Mitral valve repair in the extensively calcified mitral valve annulus.

Mitral valve replacement in patients with an extensively calcified mitral annulus is associated with an increased risk of ventricular rupture. Until now techniques of mitral valve repair have not been applied to patients with a heavily calcified mitral valve annulus. We present 12 patients who underwent extensive decalcification of the annulus with subsequent mitral valve repair between 1987 and 1990. Ages ranged from 11 to 78 years; 6 patients were in New York Heart Association functional class II, 4 were in class III, and 2 were in class IV. All patients had varying degrees of mitral insufficiency. There were no deaths, reoperations, or thromboembolic events. Postoperative echocardiography revealed minimal residual mitral insufficiency in only 2 of 12 patients. All patients are currently in New York Heart Association class I or II. We believe mitral valve repair can be done safely on patients with an extensively calcified mitral annulus, thus avoiding the risks of left ventricular rupture, thromboembolic events, and hemorrhagic complications associated with mitral valve replacement.

Mycotic aneurysms of the carotid arteries--case report and review of the literature.

Mycotic aneurysms of the extracranial carotid arteries are rare. We report a new case with a mycotic aneurysm of the carotid bifurcation associated with acute bacterial endocarditis of the aortic valve. A concomitant treatment of both lesions was performed. Twenty-six cases of mycotic aneurysms of the extracranial carotid arteries have been reported in the literature. We present a review of all these cases.

Patient management and clinical follow-up after cardiomyoplasty.

The purpose of this article is to provide an overview of patient management following latissimus dorsi cardiomyoplasty, based on clinical experience with 34 patients operated on between 1985 and 1990. Postoperative patient care includes: (1) clinical follow-up, (2) electrostimulation management, and (3) management of complications. The efficacy of cardiomyoplasty is principally evaluated by the quality-of-life before and after cardiomyoplasty (New York Heart Association [NYHA] functional class), number of rehospitalizations due to congestive heart failure, amount of pharmacological support, exercise capacity, postoperative reintegration and adaptation to working life, and late survival.

Long-term evaluation of the Carpentier-Edwards pericardial valve in the aortic position.

From July 1980 to December 1985, 124 patients underwent isolated aortic valve replacement with the Carpentier-Edwards pericardial bioprosthesis. The mean age of the patients was 64.9 +/- 13.1 years. All patients but one (0.7%) were followed for an average of 5.52 +/- 0.21 years after the operation and follow-up totaled to 677 patient-years. There were six early deaths (30-day mortality of 4.8%) and 25 late deaths (3.7% +/- 0.7% patient-year). After 9 years the actuarial survival rate was 64% +/- 14%. Six patients died of valve-related deaths (three anticoagulant-related hemorrhage, one endocarditis, one thromboembolic complication, and one sudden death) for an actuarial rate of 95% +/- 5% patients free of valve-related death at 9 years. Valve-related complications included five thromboembolic episodes (0.7% +/- 0.3% patient-year), eight anticoagulant-related hemorrhagic complications (1.2% +/- 0.4% patient-year), and two reoperations (0.3% +/- 0.2% patient-year). After 9 years, freedom from thromboembolic events was 96% +/- 4%, that from anticoagulant-related hemorrhage was 93% +/- 5%, and that from reoperation was 98% +/- 2%. There was no structural deterioration of the valve. We conclude that the Carpentier-Edwards pericardial prosthesis has a low incidence of valve-related complication and mortality within the 9-year time frame of this study.

[Advantages and limits of programmed autologous transfusion in cardiovascular surgery. Apropos of 524 patients].

Between October 1987 and July 1989, 544 patients, candidates for cardiovascular surgery, were included in a trial of programmed autologous autotransfusion. Five hundred and twenty four patients underwent one or several (maximum 4) blood donation sessions in the 3 weeks before surgery with no complications. Overall, 57% of patients benefited from homologous blood transfusion, thereby avoiding all risk of contamination. It was in the group of patients able to undergo 3 or 4 preoperative blood donations that we observed the smallest number of homologous transfusions (30%). Programmed autologous transfusion would seem to be a very useful technique for cardiac surgery, allowing a reduction in health care costs without additional patient risk. In order to improve on this method, it may be useful to associate a peroperative technique of blood recuperation in patients in whom the transfusion needs are likely to exceed the possibilities of preoperative blood donation alone.

[Mitral valvuloplasty for endomyocardial fibrosis in a child with acute leukemia and hypereosinophilia].

The authors report the case of a child with acute lymphoblastic leukaemia and hypereosinophilia complicated by left sided endomyocardial fibrosis. Despite the need for urgent treatment and severe mitral valve disease, a complex mitral valvuloplasty was performed, consisting of mobilisation and reconstruction of the posterior leaflet, burying the chordae with plicature of the papillary muscle of the anterior leaflet associated with an annuloplasty. Decortication was performed by a transvalvular approach. The technique of mobilisation-reconstruction of the posterior mitral leaflet with a pericardial patch should widen the indication of conservative surgery in this condition, in the presence of dominant mitral regurgitation in the child.

[Traumatic mitral valve insufficiency after percutaneous mitral valve angioplasty. Mechanisms and surgical technique].

Eighteen patients underwent surgery for traumatic mitral regurgitation following percutaneous mitral valvuloplasty (PMV). Three patients required emergency surgery (delay less than 6 hours). In the remaining cases, the operation was performed one week after PMW (n = 11) or delayed for up to 3 months (n = 4). The operative findings were: ruptured papillary muscle (n = 1); torn anterior leaflets (n = 4), torn posterior leaflet (n = 1), anterior paracommissural tear (n = 3), posterior paracommissural tear (n = 9). Associated lesions included left atrial thrombosis (n = 2) and greater than 1 cm atrial septal defect (n = 4). Conservative mitral valve surgery was possible in over half the cases (n = 10), including two extensive tears of the anterior leaflet. The other patients required mitral valve replacement (n = 8). There were no postoperative complications in any of the patients.
