Why the study?
The study was conducted to evaluate the hemodynamic performance and the incidence of prosthesis-patient mismatch after AVR using bovine pericardial valves.
Carpentier-Edwards Perimount Magna and Magna Ease bovine pericardial valves demonstrate satisfactory hemodynamic performance with low rates of prosthesis-patient mismatch.
Satisfactory hemodynamics and low PPM support valve selection in AVR; leaves open durability questions for prospective confirmation.
BACKGROUND: This study was conducted to evaluate the hemodynamic performance and the incidence of prosthesis-patient mismatch (PPM) after aortic valve replacement (AVR) using bovine pericardial valves (Carpentier-Edwards Perimount Magana and Magna Ease). METHODS: In total, 216 patients (mean age, 70.0±10.5 years) who underwent AVR using stented bovine pericardial valves and had follow-up echocardiography between 3 months and 2 years (mean, 12.0±6.6 months) after surgery were enrolled. The implanted valve sizes were 19, 21, 23, and 25 mm in 32, 56, 99, and 29 patients, respectively. RESULTS: ) PPM was present in 56 patients (11.8%) and 9 patients (1.9%), respectively, when using the measured values. CONCLUSION: Carpentier-Edwards Perimount Magna and Magna Ease bovine pericardial valves showed satisfactory hemodynamic performance with low rates of PPM, although the reference EOA could overestimate the true EOA for individual patients.
