Approximately 250,000 heart valve operations are performed annually worldwide. An intensive research and development effort has led to progressively more advanced heart valve prostheses. The Carpentier-Edwards Perimount Magna Ease (CEPME) prosthesis represents the latest iteration of the Edwards Perimount series of aortic tissue valves. The current study aims to evaluate the midterm performance of this bioprosthesis. Five hundred and eighteen patients with aortic stenosis underwent aortic valve replacement with the CEPME valve at Papworth Hospital between August 2008 and November 2011. After a minimum of 3 years from the index operation, eligible patients were retrospectively and consecutively recruited to participate. Recruitment was closed after 100 eligible patients had completed all study assessments. Investigations at follow-up included echocardiography, and NYHA status. Primary endpoints included valve performance measures. The mean age was 72 years, 64% were male and median follow-up was 5.1 years. NYHA status had improved in 66% of patients. The average postoperative peak and mean pressure gradients decreased by 51.2 mmHg (64.5%) and 31.8 mmHg (59.4%), with a significant improvement in NYHA status. The frequency of moderate aortic regurgitation was 3%. There was no evidence for structural valve deterioration. The CEPME has excellent mid-term durability. Its use effectively improves haemodynamics and functional capacity.
