A 56-year-old female had a severely calcified mitral valve annulus and a huge subvalvular mass. To avoid critical damages of the coronary artery and left ventricle, the annular calcification and the part of the mass adherent to the left ventricle were not resected. Then we performed mitral valve replacement using SuMit valve and collared reinforcement technique with xenopericardium without any major complications. The SuMit valve is designed to be placed in a supraannular position, and is useful to prevent valves from getting stuck.
一名56岁女性患有严重钙化的二尖瓣环和巨大的瓣下肿物。为避免冠状动脉和左心室受到严重损伤，未切除环状钙化灶及与左心室粘连的部分肿物。然后我们使用SuMit瓣膜并采用带环加固技术，用人心包进行二尖瓣置换，未出现任何重大并发症。SuMit瓣膜设计为置于瓣环上方位置，有助于防止瓣膜卡瓣。
