经导管二尖瓣缘对缘修复治疗梗阻性肥厚型心肌病PIMSRA失败1例

Transcatheter edge-to-edge mitral valve repair for the treatment of failed after PIMSRA for obstructive hypertrophic cardiomyopathy:a case report

本文报道1例梗阻性肥厚型心肌病经皮心肌内室间隔射频消融术治疗后7个月消融区组织未完全吸收、左心室流出道梗阻未解除并发重度二尖瓣反流的病例,利用经导管二尖瓣缘对缘修复治疗后二尖瓣反流显著减少的同时左心室流出道梗阻得到解除。望对类似病例提供借鉴。

Here we report a case of hypertrophic obstructive cardiomyopathy,in which left ventricular outflow obstruction and severe mitral regurgitation were detected seven months after the percutaneous intramyocardial septal radiofrequency ablation(PIMSRA),caused by incomplete absorption of tissue in the ablation area.After performing the transcatheter edge-to-edge mitral valve repair(TEER),the mitral regurgitation was reduced significantly,and the left ventricular outflow obstruction was relieved.We hope to provide references for similar cases.
