Postoperative residua and sequelae in adults with repaired tetralogy of Fallot.

Postoperative residua and sequelae after repair of tetralogy of Fallot in adults became one of the major concerns in the field of adult congenital heart disease. Right heart failure and arrhythmia can result fatal, and are considered to be related dilated right ventricle due to pulmonary valve regurgitation. Although precise indication of pulmonary valve replacement (PVR) is still not established, right ventricular end-diastolic volume index less than 150-170 ml/m(2) and right ventricular end systolic volume index less than 82-90 ml/m(2) may be border line for RV remodeling after PVR. Biological prosthetic valve is generally used at the pulmonary position.
