Injury of the left circumflex coronary artery is a potentially serious complication of mitral valve surgery due to the proximity of the vessel to the posterior segment of the mitral annulus. Suture-related distortion of the artery with partial or subtotal occlusion is the most commonly implicated mechanism. Herein, we present a case of symptomatic iatrogenic circumflex coronary artery stenosis following mitral valve annuloplasty for degenerative mitral valve regurgitation.
左旋冠状动脉损伤是二尖瓣手术潜在的严重并发症,因为该血管靠近二尖瓣环的后段。与缝线相关的动脉扭曲伴部分或几乎完全闭塞是最常见的相关机制。在此,我们报告一例因退行性二尖瓣反流行二尖瓣环成形术后出现症状性医源性左旋冠状动脉狭窄的病例。
