Long-term results of left ventricular reconditioning and anatomic correction for systemic right ventricular dysfunction after atrial switch procedures

Abstract

Objectives: Systemic right ventricular failure after atrial switch procedures for transposition of the great arteries has been addressed at Melbourne's Royal Children's Hospital (1981-1993) and the Cleveland Clinic Foundation (1993-2001) with reconditioning of the morphologically left ventricle by means of pulmonary artery banding followed by an arterial switch operation and an atrial reseptation. Methods: Thirty-nine patients (Royal Children's Hospital, 19; Cleveland Clinic Foundation, 20) with a median age of 10.8 years (range, 13 months-24 years) entered this protocol a median of 10.3 years (range, 0.5-24 years) after an atrial switch procedure. Results: The median duration of pulmonary a..
