Abstract

OBJECTIVE: 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 cm

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.
