Aortic valve repair with pericardial leaflet extension for aortic valve insufficiency

Abstract

Background: This article presents our intermediate term results of pericardial leaflet extension used in various complex pathologies of the aortic valve leading to aortic regurgitation.

Methods: Sixteen patients had aortic insufficiency/regurgitation with deficient leaflet tissues so that repair was performed with pericardial leaflet extension. The mean patient age was 26.6 years and 69% were male. Two patients (13%) were in NYHA class I, 12 patients (75%) were in class II and 2 patients (13%) were in class III preoperatively. Six patients (38%) had a bicuspid aortic valve and 10 patients (63%) had a tricuspid aortic valve. Eight patients (50%) had moderate and 8 patients (50%) had severe aortic insufficiency (AI) preoperatively. Two patients (13%) had associated cardiac procedures at the time of aortic repair.

Results: There were no operative deaths but 3 patients died in the late postoperative period. Five patients underwent subsequent aortic valve replacement or a Ross procedure at re-operation. The most common finding during re-operation was thickening of the leaflet extension or rolling in of the edges of the leaflet extension. Freedom from aortic valve re-operation at five years postoperation was 68% (standard error 14). Late follow-up revealed that 9 patients (56%) were in NYHA class I and 7 patients (44%) were in class II. Ten (63%) patients had mild AI and 6 patients (37%) had moderate AI at most recent follow-up.

Conclusions: Absence of hospital mortality, freedom from embolic events and echocardiography evidence of immediate competency of the valve are the reliable indicators of this surgical technique.
