Diseased, replaced or repaired mitral valve can lead to restricted blood flow to left ventricle and inadequate flow in left ventricular assist device (LVAD). A middle age woman with 'burnt out' hypertrophic cardiomyopathy had mitral valve repair for mitral regurgitation. She needed LVAD to support severe decompensating heart failure. Repaired mitral valve posed a risk of restricted flow through the device. Mitral commissurotomy was performed on beating heart through the left ventricular apical hole created for insertion of inflow cannula of LVAD.
病变、置换或修复后的二尖瓣可导致左心室血流受限以及左心室辅助装置(LVAD)血流不足。一名患有“终末期”肥厚型心肌病的中年女性因二尖瓣反流接受了二尖瓣修复术。她需要LVAD来支持严重失代偿性心力衰竭。修复后的二尖瓣存在导致装置内血流受限的风险。通过为LVAD流入插管插入而在跳动的心脏上经左心室心尖孔进行了二尖瓣交界切开术。
