“Objective: The most common reason for late surgical reintervention after repair of complete atrioventricular canal defects is the development of left atrioventricular valve www.selleckchem.com/products/gsk126.html regurgitation. We sought to determine the changes in left atrioventricular valve geometry after surgical repair that may predispose to regurgitation.

Methods: Atrioventricular valve measurements were obtained by 2-dimensional echocardiography at 3 different time points (preoperative, early postoperative, selleck chemical and midterm postoperative [6-12

months]). Left atrioventricular valve annulus area and left ventricular volume were calculated; vena contracta of the regurgitant jet orifice was measured. All measurements were normalized relative to an appropriate power of body surface area.

Results: From January 2000 to January 2008, 101 patients with complete atrioventricular canal repair were included. Left atrioventricular valve annulus was noted to remodel from an elliptical shape to a circular shape after surgery. Left atrioventricular valve annulus area increased early postoperatively (systole: 4.1 +/- 0.2 cm(2)/m(2) vs 6.1 +/- 0.3 cm(2)/m(2), P < .001; diastole: 7.2 +/- 0.4 cm(2)/m(2) vs 10.0 +/- 0.5 cm(2)/m(2), P < .001, pre- vs postoperative, respectively). This increase was sustained in the midterm postoperative period (systole: 6.1 +/- 0.3 cm(2)/m(2), P = .85, vs diastole: 10.0 +/- 0.4 cm(2)/m(2), P = .78, early vs midterm postoperative). Left ventricular volume increased in the early and midterm postoperative periods compared with preoperative (systole: 16.9 +/- 1.2 mL/m(2) vs 26.2 +/- 1.7 mL/m(2), P < .001; diastole: 35.0 +/- 2.4 mL/m(2) vs 52.5 +/- 3.2 mL/m(2), P < .001).

Conclusions: Complete atrioventricular canal repair leads to left atrioventricular valve annular shape change with increased area and circular shape.
