ABSTRACT

Stentless aortic bioprostheses have been successfully used for over a decade. The 3f bioprosthesis is a new equine pericardial stentless valve, unique in its tubular design, preserving the native aortic sinuses post-implant. Forty-six consecutive aortic valve replacements with the 3f bioprosthesis were performed between June 2003 and January 2005. The patients were prospectively assessed and echocardiography was performed at 6 months, 12 months, and annually thereafter. The median follow-up was 2.1 ± 0.9 years. There was one early and 4 late deaths; none were valve-related. The 2-year mean transvalvular gradient was 8.8 ± 3.8 mm Hg, the mean echocardiographic aortic regurgitation grade was 0.4 ± 0.7 (grade 1 being trivial). Echocardiographic sizing of the aortic annulus before surgery accurately predicted prosthesis size. The 3f bioprosthesis is easy to implant. Early clinical results are favorable, with hemodynamic profiles consistent with those of other stentless prostheses. Longer follow-up is required to confirm its durability.
