Key result
Case report describes valve-sparing aortic root replacement for severe neo-aortic regurgitation and pulmonary autograft dilatation.
Why the study?
Reoperation after the Ross procedure commonly requires neo-aortic valve replacement, but valve-preserving aortic root replacement with leaflet prolapse correction is an emerging alternative.
Case Report (n=1)
Valve-sparing aortic root replacement with leaflet prolapse repair is a feasible alternative to composite replacement for patients with neo-aortic valve regurgitation after a Ross procedure.
Offers valve-sparing option for post-Ross neo-aortic regurgitation with prolapse; leaves open durability versus composite replacement.
The need for reoperation remains a principal limitation of the Ross procedure and most commonly includes replacement of the neo-aortic valve. Valve-preserving aortic root replacement has recently evolved into an increasingly accepted treatment modality for patients with neo-aortic valve regurgitation. Leaflet prolapse, however, may be present, making composite replacement the most frequent choice. Alternatively, valve preservation may be combined with correction of leaflet prolapse. We describe the use of a valve-sparing procedure with correction of leaflet prolapse in a patient with progressive dilatation of the pulmonary autograft and severe regurgitation of the neo-aortic valve.

Watanabe et al. (2006) conducted a case report in Progressive dilatation of the pulmonary autograft and severe regurgitation of the neo-aortic valve after Ross operation (n=1). Valve-sparing aortic root replacement with repair of leaflet prolapse was evaluated. A valve-sparing aortic root replacement with correction of leaflet prolapse was described in a patient with progressive pulmonary autograft dilatation and severe neo-aortic valve regurgitation.
