Abstract

OBJECTIVES: The COMMENCE trial was conducted to evaluate the safety and effectiveness of a novel bioprosthetic tissue for surgical aortic valve replacement (AVR). METHODS: Patients underwent clinically indicated surgical AVR with the Carpentier-Edwards PERIMOUNTTM Magna EaseTM aortic valve with RESILIATM tissue (Model 11000A) in a prospective, multinational, multicentre (n = 27), single-arm, FDA Investigational Device Exemption trial. Events were adjudicated by an independent Clinical Events Committee; echocardiograms were analysed by an independent Core Laboratory. RESULTS: Between January 2013 and February 2016, 689 patients received the study valve. Mean age was 67.0 ± 11.6 years; 71.8% were male; 26.3% were New York Heart Association Class III/IV. Mean STS PROM was 2.0 ± 1.8 (0.3-17.5). Isolated AVR was performed in 59.1% of patients; others had additional concomitant procedures, usually CABG. Thirty-day outcomes for all patients included all-cause mortality 1.2%, thromboembolism 2.2%, bleeding 0.9%, major paravalvular leak 0.1% and permanent pacemaker implantation 4.7%. Median intensive care unit and hospital length of stay were 2 (range: 0.2-66) and 7 days (3.0-121.0), respectively. At 2 years, New York Heart Association class improved in 65.7%, effective orifice area was 1.6 ± 0.5 cm2; mean gradient was 10.1 ± 4.3 mmHg; and paravalvular leak was none/trivial in 94.5%, mild in 4.9%, moderate in 0.5% and severe in 0.0%. One-year actuarial freedom from all-cause mortality for isolated AVR and for all patients was 98.2% and 97.6%, respectively. Two-year actuarial freedom from mortality in these groups was 95.3% and 94.3%, respectively. CONCLUSIONS: These data demonstrate excellent early safety and effectiveness of aortic valve replacement with a novel bioprosthetic tissue (RESILIATM).
