Abstract
Aortic dilatation is constantly observed in unrepaired or repaired congenital heart diseases (CHD). Aortic dilatation might cause aortic annular enlargement that will predispose to severe aortic regurgitation (AR). In such conditions, concomitant aortic valve plasty or replacement with aortic root replacement will be required. Bentall operation is root replacement with an aortic tube graft and a mechanical valve. Coronary ostia are reimplanted to the aortic graft. Remodeling method (Yacoub) and reimplantation method (David) had been developed in order to preserve the aortic valve with the same concept as the Bentall operation. These procedures are well known as valve-sparing operations. On the other hand, in Ross procedure a pulmonary autograft is used to replace the aortic root and aortic valve. RV outflow tract and pulmonary artery are reconstructed usually with homograft or other valved conduits. Superior hemodynamics, freedom from anticoagulation, and longevity of pulmonary autografts have been substantiated in many reports.
