Double‐Orifice Repair for Left Atrioventricular Valve Regurgitation in Atrioventricular Septal Defect: Report of Two Cases

Abstract  We describe two patients who successfully underwent a surgically created double‐orifice repair using the edge‐to‐edge repair for residual left atrioventricular valve (LAVV) regurgitation in an atrioventricular septal defects (AVSD). Both patients had previously received patch closure of the AVSD and partial closure of a cleft of the LAVV. Preoperatively, echocardiography showed a wide open cleft and remarkable dilatation of the LAVV annulus. Doppler study revealed severe regurgitation through the cleft and the central portion of the LAVV orifice and no intracardiac shunt. Postoperative echocardiography showed a remarkable decrease of the AV valve regurgitation to none or trivial levels without stenosis of the LAVV in both patients. Among several valve‐sparing techniques, our experience suggests that the surgically created double‐orifice repair is one of the most effective reparative procedures for LAVV regurgitation in AVSD.
