Congenital subaortic stenosis by accessory mitral valve tissue, recognition and management.

Accessory mitral valve tissue as the single cause for left ventricular outflow tract obstruction is a very rare cardiac malformation in normally connected hearts. We report a case in which this condition was present as single cause for left ventricular outflow tract obstruction. The surgical technique is described and a review of the literature presented.

Congenital quadricuspid aortic valve associated with congenital complete heart block.

Congenital quadricuspid aortic valve is very uncommon, and is often associated with other cardiac disorders, such as patent ductus, ventricular septal defect, pulmonary stenosis, mitral valve malformation, hypertrophic cardiomyopathy and coronary abnormalities. We report a patient with congenital quadricuspid aortic valve associated with congenital complete heart block. To our knowledge, this association has not been reported so far.

Valvular flow abnormalities are often identified by a resting focused Doppler examination performed at the time of stress echocardiography.

BACKGROUND: Patients are usually referred for stress echocardiography to assess whether there is inducible myocardial ischemia. At some centers, a focused Doppler examination is also performed. We sought to determine the clinical value of this additional study by examining how often valvular flow abnormalities were identified that might affect clinical care. METHODS: We reviewed 1272 consecutive stress echocardiogram reports from a 1-year period, including 1223 tests that contained focused Doppler data. Important Doppler findings were defined as at least moderate mitral regurgitation, at least mild aortic regurgitation, any aortic or mitral valve stenosis, or any resting left ventricular outflow tract gradient. RESULTS: Overall, focused Doppler identified an important Doppler abnormality in 214 patients (17%). At least moderate mitral regurgitation was identified in 67 patients (5%) and at least mild aortic regurgitation was identified in 163 patients (13%). In addition, aortic stenosis (n = 14; 1%), mitral stenosis (n = 5; 0.4%), and resting outflow tract gradient (n = 2; 0.2%) were noted. A prior echocardiogram had been performed at our institution in 317 patients (26%). For this subset, a new important Doppler finding, a two-step change in regurgitant grade, or a one-step change in stenosis severity was noted in 28 patients (9%). Among patients who had a previous study, the prevalence of new findings was the same (9%) in those who had been studied within the previous year as in those whose previous study had been performed more than 2 years before. CONCLUSION: Focused Doppler documents valvular flow abnormalities in 17% of patients referred for stress echocardiography, thereby enhancing the potential overall value of the test. The frequency of new findings was independent of the time interval from the previous Doppler study. These data should be considered when clinicians choose a stress imaging modality.

[Left ventricular performance following mitral valve replacement in patients with tight mitral stenosis combined with mild aortic regurgitation].

The severity of aortic regurgitation is difficult to estimate prior to mitral valve replacement (MVR) in cases with tight mitral stenosis (MS), because low output state due to mitral obstruction masks signs of aortic regurgitation. This study clarified left ventricular performance, possibly affected by increased diastolic loading after MVR. The study subjects consisted of 12 patients with pure mitral stenosis (MS group) and 11 with combined mitral stenosis and aortic regurgitation (MSAR group). The diagnosis was made by cardiac catheterization preoperatively. The aortographic grade of aortic regurgitation was class 1 or 2 according to the AHA classification. Both groups were matched in terms of severity in mitral obstruction evaluated by mitral valve area. On preoperative echocardiographic evaluation, there was no difference in the mean values of LVDd, LVSd, and %FS between the groups MS and MSAR. After surgery, symptoms improved in each patient. Echocardiography performed three months after MVR revealed no differences in these parameters between both the groups. We concluded that aortic regurgitation evaluated as class 1 or 2 preoperatively does not increase in respect to left ventricular diastolic overloading and echocardiographic left ventricular performance remains unchanged.
