Abstract

BACKGROUND: In Guideline for Surgical and Interventional Treatment of Valvular Heart Disease, revised by Japanese Circulation Society in 2012, mitral valve replacement (MVR) with bioprosthesis is class II b recommendation for patients aged 70 years or older who have no risk factors for thromboembolism. The aim of this study was to evaluate the early postoperative surgical outcomes and the hemodynamic performance with the Epic mitral bioprosthesis.

METHODS: Twenty-six consecutive patients underwent MVR with Epic mitral bioprostesis at Tohoku University Hospital between April 2011 and July 2014. Twenty-five cases of 26 were evaluated their hemodynamics at discharge, and of which 19 cases of 26 were evaluated at the outpatient clinic during follow-up period.

RESULTS: There was 1 hospital death. Long-term mortality or reoperation for any valve abnormality was not observed in the median follow-up of 23.9 ± 11.3 months. Hemodynamic date at discharge obtained by transthoracic echocardiography included mean hemodynamics of mitral valve bioprosthesis as below. Effective orifice area (EOA):2.44 ± 0.62 cm², peak mitral pressure gradient (pMPG):15.8 ± 5.3 mmHg, mean mitral pressure gradient(mMPG):7.2 ± 2.4 mmHg. Hemodynamic parameters at follow-up were found to be stable as EOA:2.25 ± 0.64 cm², pMPG:17.3 ± 5.7 mmHg, mMPG:6.2 ± 2.3 mmHg, respectively.

CONCLUSION: We have attempted to elucidate our preliminary postoperative outcomes and hemodynamics after MVR with Epic mitral bioprosthesis. These in vivo hemodynamic data can serves a clinical reference.
