Mitral valve repair or replacement poses a potential risk of injury to the left circumflex coronary artery (LCx). Such injuries can arise from either direct LCx injury caused by encircling or transfixing stitches, or indirect occlusion resulting from the distortion of adjacent tissues. We provide and illustrate a representative image depicting LCx distortion. Additionally, we offer guidance to aid angiographers in comprehending the angiographic appearance and the underlying mechanism of occlusion.

二尖瓣修复术后回旋变形


二尖瓣修复或置换会对左冠状动脉（LCx）造成潜在的损伤风险。这种损伤可能是由于环绕或刺穿缝合引起的直接 LCx 损伤，或由于邻近组织变形引起的间接闭塞。我们提供并说明了描绘 LCx 失真的代表性图像。此外，我们还提供指导，帮助血管造影医生理解血管造影的外观和闭塞的潜在机制。
