Surgical strategy for the bicuspid aortic valve: Tricuspidization with cusp extension versus pulmonary autograft

Abstract

Objective: The congenitally bicuspid aortic valve is the most common etiologic factor associated with clinically significant aortic stenosis and/or regurgitation in pediatric patients. Beyond infancy, surgical intervention typically involves valve repair with cusp thinning and commissurotomy or valve replacement, primarily with pulmonary autograft in the current era. An aortic valve repair technique using tricuspidization with cusp extension was introduced in 1999. This study compares the midterm clinical outcome in patients undergoing valve repair by tricuspidization with cusp extension with those receiving a pulmonary autograft (Ross). Methods: A retrospective study was performed on all co..
