Outcomes of Florida Sleeve Procedure in Patients with Bicuspid Versus Tricuspid Aortic Valve

Abstract

Objective

Outcomes of the Florida Sleeve (FS) procedure in patients with bicuspid aortic valve (BAV) have not been reported before. We compared outcomes of the FS procedure between patients with BAV and those with tricuspid aortic valve (TAV).

Methods

From May 1, 2002 to January 1, 2016, 177 patients including 18 BAV and 159 TAV underwent the FS procedure. Baseline characteristics, perioperative outcomes, and echocardiographic measurements were compared between the 2 groups. Kaplan–Meier and life-table analyses were used to evaluate survival and freedom from reintervention rates.

Results

Mean ± standard deviation age and aortic root diameter were comparable in BAV and TAV groups, 47.83 ± 11.19 versus 49.59 ± 15.79 years (P = 0.55) and 56.57 ± 6.18 versus 55.17 ± 8.84 mm (P = 0.46), respectively. The 30-day mortality and stroke rates were zero in the BAV group and 1.88% (n = 3) in the TAV group (P = 1.00). One patient (5.55%) in the BAV group and 8 (5.03%) patients in the TAV group needed permanent pacemaker implantation (P = 0.62). Freedom from reoperation was 93% in the BAV group and 99% in the TAV group at 8 years (P = 0.041). Patient survival rate was 100% in the BAV group and 91% in the TAV group at 8 years (P = 0.42). Freedom from aortic insufficiency greater than mild was 93% in the BAV group and 96.5% in the TAV group at 5 years (P = 0.61).

Conclusions

This is the first study reporting outcomes of the FS procedure in patients with BAV. This technique is feasible, and the results appear to be durable when compared to patients with TAV.
