Retrospective studies have been conducted in Lyon (33 patients) and Montreal (24 patients) in order to compare the results of transventricular valvotomy (TVV, 20 cases) and aortic valvotomy with cardiopulmonary bypass (CPB, 37 cases) in neonatal critical aortic stenosis. Clinical, echocardiographic, catheterization and operative data were analyzed in order to determine prognostic factors. Mortality rate was 59%: 30/34 perioperative deaths in the first month, and 4 late deaths after a reintervention for severe residual obstruction. Long term follow up was available for 23 patients (41%) for a 2 to 16 year period (mean 7.5). Five patients (7%) required a reintervention six years after the initial operation. Two of them required valve replacement. Eighteen patients (31%) surviving the initial operation, displayed a satisfactory result, being free of symptoms, endocarditis, reoperation and sudden death. Factors that influenced the outcome included severe heart failure, a left ventricular end-diastolic diameter below 14 mm, an aortic valve annulus below 8 mm, and a poor shortening fraction. Factors that did not influence the prognosis were age, pulmonary hypertension, and the anatomic type of the valve. Trans-aortic valvotomy with CPB was associated with a smaller operative mortality and a better long term result than TVV.
