Long-Term Functional Analysis of the Atrioventricular Valve in Patients Undergoing Single Ventricle Palliation

If performed properly, atrioventricular valve repair may neutralize the risk of regurgitation regardless of the valve morphology. The effort to incorporate the mitral valve into the systemic circulation may be important to reduce tricuspid regurgitation. The effort to decompress a nonsystemic left ventricle, if present, may be important to avoid unfavorable ventricular interactions on the mitral valve.
