Abstract

This study aimed to identify and characterize patients who developed prosthetic dehiscence after aortic valve replacement with the Freestyle Stentless bioprosthesis. Review of patients' records and preoperative echocardiogram was performed. Prosthetic dehiscence developed in 10 patients after 2.5 to 49 months (mean 19). Most patients were symptomatic at presentation. Nine patients were reoperated. Dehiscence was typically located at the inflow suture line beneath the noncoronary cusp. Four patients died. The cause of dehiscence is assumed to be related primarily to surgical technique.
