The angle of the components of the common atrioventricular valve predicts the outcome of surgical correction in patients with atrioventricular septal defect and common atrioventricular junction
Background: Three-dimensional echocardiography offers new insights into valvar function in atrioventricular septal defects (AVSDs). The aim of this study was to identify a morphological marker to predict the functional outcomes of left atrioventricular valves (AVVs) following the repair of AVSDs.

Methods: Twenty-nine consecutive patients were evaluated preoperatively using 2-dimensional and 3-dimensional echocardiography. The angle of the AVV relative to the crux of the heart was measured in multiplanar review mode.

Results: The severity of postoperative left AVV regurgitation was correlated with preoperative valvar angle, being more acute in patients with moderate or severe regurgitation (mean, 57 ± 13° vs 83 ± 9° in patients with no or mild regurgitation; P = .002). Angles ? 59° predicted severe regurgitation with 79% specificity.

Conclusions: Multiplanar review of 3-dimensional data sets is valuable for the assessment of the functional morphology of AVSD valves. Using this technique, more acute AVV angles predicted increased likelihood of severe regurgitation following surgical repair.

Abstract

Background: Three-dimensional echocardiography offers new insights into valvar function in atrioventricular septal defects (AVSDs). The aim of this study was to identify a morphological marker to predict the functional outcomes of left atrioventricular valves (AVVs) following the repair of AVSDs.

Methods: Twenty-nine consecutive patients were evaluated preoperatively using 2-dimensional and 3-dimensional echocardiography. The angle of the AVV relative to the crux of the heart was measured in multiplanar review mode.

Results: The severity of postoperative left AVV regurgitation was correlated with preoperative valvar angle, being more acute in patients with moderate or severe regurgitation (mean, 57 ± 13° vs 83 ± 9° in patients with no or mild regurgitation; P = .002). Angles ? 59° predicted severe regurgitation with 79% specificity.

Conclusions: Multiplanar review of 3-dimensional data sets is valuable for the assessment of the functional morphology of AVSD valves. Using this technique, more acute AVV angles predicted increased likelihood of severe regurgitation following surgical repair.
