Abstract

BACKGROUND: Severe right ventricular (RV) dilatation and exercise intolerance are considered indications for pulmonary valve replacement in surgically repaired tetralogy of Fallot (rTOF). METHODS AND RESULTS: , respectively. RV and left ventricular (LV) ejection fractions were 50.3±7.8% and 59.1±6.1%, respectively. A strong positive correlation was noted between RV end-diastolic volume and RVSV (P
