BackgroundAn important factor in the management and outcome of patients with complex univentricular or partial biventricular repair is atrioventricular valve function. Cross-sectional and Doppler echocardiography are versatile tools for the evaluation of atrioventricular valve function. However, it is important to understand the physics and applications of this technology to appreciate the strengths and limitations of echocardiography in this application.Methods And ResultsIn this review, we discuss the preoperative and intraoperative echocardiographic evaluation of atrioventricular valve function in congenital heart disease. The focus is on atrioventricular valve regurgitation, which is the most common type of dysfunction in patients with univentricular or partial biventricular heart disease. We emphasize an understanding of basic jet physics, as well as technical considerations in the evaluation of atrioventricular valve function, with illustrations from our own experience.ConclusionsCross-sectional and Doppler cardiac ultrasound is the optimal tool for evaluation of atrioventricular valve function in the current era. Although the issue of quantifying regurgitant jets is not yet fully resolved, echocardiography allows for complete qualitative assessment of the anatomic and functional features that influence the function of the atrioventricular valves.
