A Surgical Technique to Preserve the Subvalvular Apparatus in Patients Undergoing Mitral Valve Replacement for Severe Ischemic Regurgitation

ABSTRACT Severe functional mitral valve regurgitation should be treated in patients undergoing myocardial revascularization. When replacement is considered the best therapeutic option, preservation of the mitral subvalvular apparatus is crucial, especially in the emergency setting, because of its primary role in preserving geometry and function of left and right ventricles. Here we present a simple and quick technique, where subvalvular apparatus is preserved in toto in patients undergoing mitral valve replacement with a bioprosthesis.

摘要：接受心肌血运重建术的患者若合并重度功能性二尖瓣反流，应予以治疗。当二尖瓣置换被确定为最佳治疗方案时，保留二尖瓣瓣下结构至关重要，尤其在急诊情境中，因其在维持左、右心室的几何形态与功能方面具有核心作用。本文介绍一种简便快捷的手术技术，可在采用生物瓣膜（bioprosthesis）行二尖瓣置换术的患者中完整保留瓣下结构。
