Abstract

A 72-year-old patient with quadricuspid aortic valve underwent transcatheter aortic valve replacement due to severe valve stenosis with moderate insufficiency. During the procedure, the right coronary artery was protected as originally planned. However, after the artificial valve was released, the left coronary artery was found to be blocked, so a coronary protection stent was implanted in the left coronary artery ostium under the guidance of intravascular ultrasonography. The case indicates that for patients with a quadricuspid aortic valve undergoing transcatheter aortic valve replacement, in addition to preoperative measurement of the aortic root, attention should also be paid to the coronary artery obstruction caused by the displacement of the artificial valve frame during the procedure.

经导管四尖瓣主动脉瓣置换术中冠状动脉保护一例。
一位72岁的四尖瓣主动脉瓣患者因瓣膜严重狭窄伴中度不全而行经导管主动脉瓣置换术。手术过程中,右冠状动脉按原计划得到保护。但人工瓣膜释放后发现左冠状动脉闭塞,在血管内超声引导下在左冠状动脉开口植入冠状动脉保护支架。本病例提示,对于经导管主动脉瓣置换术的四尖瓣主动脉瓣患者,除术前测量主动脉根外,还应注意术中人工瓣膜架移位引起的冠状动脉阻塞。
