title: Early outcomes and hemodynamics after implantation of the Trifecta aortic bioprosthesis.
abstract: OBJECTIVE
  The Trifecta valve is a recent, newly designed high performance valve, with few studies on the clinical and hemodynamic data. The purpose of this study was to evaluate the early clinical and echocardiographic results of the Trifecta valve.
  
  
  METHODS
  Between April 2012 and December 2012, 23 consecutive patients underwent aortic valve replacement with the Trifecta valve in our institution. Clinical and hemodynamic data were prospectively recorded and hemodynamic performance was assessed by transthoracic echocardiography.
  
  
  RESULTS
  Nine patients were male and the overall mean age was 75 ± 9 years. Twenty patients suffered aortic stenosis, and 3 suffered aortic insufficiency. Prosthesis sizes implanted were: 19 mm (n = 4), 21 mm (n = 12), and 23 mm (n = 7). There were no 30-day deaths and no valve-related events during follow-up, except for 1 postoperative stroke. The mean postoperative transprosthetic pressure gradient was 10.0 ± 1.4, 9.6 ± 3.6, and 7.1 ± 3.6 mmHg, and the effective orifice area was 1.45 ± 0.13, 1.68 ± 0.16, and 1.90 ± 0.28 cm(2), for valve sizes 19, 21, and 23 mm, respectively. One patient had moderate prosthesis-patient mismatch. No moderate to severe aortic regurgitation was observed. The mean pressure gradient in aortic stenosis patients decreased significantly from 49.9 ± 20.7 to 8.9 ± 3.6 mmHg (p < 0.001). Left ventricular mass index in all patients decreased significantly from 142.0 ± 33.6 to 115.4 ± 26.4 g/m(2) (p < 0.001).
  
  
  CONCLUSIONS
  The Trifecta aortic bioprosthesis provided satisfactory early outcomes and hemodynamic function.
