Abstract
OBJECTIVES: The St Jude Medical (SJM) Trifecta bioprosthesis is a recently introduced stented trileaflet pericardial valve designed for supra-annular replacement of the aortic valve (AVR). We sought to evaluate the short-term clinical outcome and haemodynamic performance of the Trifecta valve after AVR. METHODS: A total of 837 patients with severe symptomatic aortic valve stenosis or regurgitation underwent AVR with the SJM Trifecta aortic valve prosthesis between January 2009 and March 2013. All intra- and postoperative data were collected prospectively. At discharge, transthoracic echocardiography was performed. A complete set of echocardiographic data was available in 723 patients. RESULTS: Adjusted mean systolic pressure gradients (MPGs) for valve sizes 19 (n = 37/4.4%), 21 (n = 192/22.9%), 23 (n = 263/31.4%), 25 (n = 202/24.1%), 27 (n = 100/11.9%) and 29 mm (n = 42/5.0%) were 8.6 ± 1.1, 8.7 ± 0.4, 7.2 ± 0.3, 6.2 ± 0.3, 5.6 ± 0.3 and 3.9 ± 0.4 mmHg, respectively. Mean effective orifice area (EOA) for valve sizes 19, 21, 23, 25, 27 and 29 mm were 1.5 ± 0.09, 1.6 ± 0.04, 1.9 ± 0.03, 2.0 ± 0.03, 2.2 ± 0.05 and 2.7 ± 0.01 cm(2), respectively. No patient-prosthesis mismatch (PPM) was seen in 71.3% of patients (EOAI >0.85 cm(2)/m(2)). Moderate mismatch (EOAI 0.65-0.85 cm(2)/m(2)) was observed in 23.9% of patients, whereas severe PPM (EOAI <0.65 cm(2)/m(2)) occurred in 4.4% of patients. No malfunction of the prosthesis, endocarditis, valve thrombosis or relevant aortic regurgitation necessitating surgical revision was observed until discharge. CONCLUSIONS: The SJM Trifecta valve reveals an excellent early haemodynamic performance with low residual MPGs and a low incidence of PPM. Studies with longitudinal clinical and echocardiographic assessments with longer term follow-up evaluation including a comparison with other contemporary bioprostheses are needed.
