Midterm, multicenter clinical and hemodynamic results for the Trifecta aortic pericardial valve

To evaluate the midterm hemodynamic performance and clinical outcomes of the Trifecta aortic pericardial valve. Methods In a multicenter, prospective, nonrandomized, follow-up study, 710 patients underwent surgical implantation of a pericardial stented aortic prosthesis (Trifecta valve; St Jude Medical, St. Paul, Minn). The valve is constructed from bovine pericardium mounted externally onto a titanium stent. Subjects were followed on an annual basis over 6 years. Results Operations were performed from 2007 to 2009, and mean age was 72.4 ± 9.3 years; 471 of 710 (66.3%) were men. Preoperatively, 361 of 710 (50.8%) of patients were in New York Heart Association class III or IV, and at 6 years postoperatively, 92 of 96 (95.8%) were New York Heart Association class I or II. Six years postoperatively, average mean gradient across all valve sizes was 11.0 mm Hg, and the average effective orifice area index was 0.80 cm2/m2. The proportion of patients without moderate-to-severe valvular regurgitation at 6 years was 95.2% (80/84). Six years postoperatively, freedom from valve-related mortality, nonstructural dysfunction, and paravalvular leak were 98.3%, 98.6%, and 98.9%, respectively, and freedom from reoperation due to structural valve deterioration was 97.3% (95% confidence limits, 98.6-94.7). Conclusion These midterm results demonstrate that the Trifecta valve is a safe and effective valve substitute with excellent hemodynamic performance and durability that is maintained through the 6-year follow-up period.
