Reoperation for significant residual regurgitation across the left atrioventricular valve continues to be the major cause for morbidity, both early and late.
Regurgitation of the left atrioventricular valve was evaluated only after the patient had been weaned from cardiopulmonary bypass and was hemodynamically stable.
Postoperative echocardiography showed a satisfactory intracardiac repair with no residual shunts and minimal regurgitation across the left atrioventricular valve.
In patients with an atrioventricular anastomosis, cine recordings were reviewed for systolic regurgitation from the rudimentary right ventricle into the right atrium.
The second possibility is that a subclinical degree of tricuspid regurgitation led to hypertrophy and dilatation of the left atrium and precipitated atrial fibrillation.
Postoperative injection at the site of the anastomosis between the homograft and the pulmonary arteries shows dilatation of the homograft with pulmonary regurgitation.
Two of them had parachute valves and one developed grade 2 mitral regurgitation.
Within the next 3 years, four more valves were replaced because of severe regurgitation.
