Konno Aortoventriculoplasty and Mitral Valve Replacement in a Child With AV Septal Defect
The authors demonstrate a fourth-time redo sternotomy for an eight-year-old girl who had prior repair of an atrioventricular septal defect. An eight-year-old girl who had prior repair of atrioventricular septal defect underwent multiple prior reoperations, including repair and subsequent mechanical left AV valve replacement. Her current problem was shortness of breath with patient prosthesis mismatch, severe aortic regurgitation with left ventricular fibromuscular outflow tract obstruction, and severe tricuspid regurgitation. Through a fourth-time redo sternotomy, the authors performed a left AV valve re-replacement with a 19 mm St Jude mechanical valve, a Konno aortoventriculoplasty using a 19 mm Onyx mechanical valve, and an eccentric banded tricuspid annuloplasty. Separation from bypass was uneventful, with normal hemodynamics and sinus rhythm.
