Minimally invasive aortic valve replacement through a right thoracotomy is frequently performed in patients with aortic valve disease. The Cor-Knot Device (LSI Solutions) is an automated fastener that secures valve sutures. This case report is for a patient who developed postcardiotomy shock during a minimally invasive aortic valve surgery. The patient was found to have an aortic root dissection involving 90% of the aortic root circumference, including bilateral coronary ostia. The autopsy revealed that the aortic damage could be explained by a direct aortic intimal tear from the distal tip of the device shaft. The device was most likely not in perfect apposition to the sewing ring because of the restricted angle and space between the ribs.
经右胸小切口微创主动脉瓣置换术常用于主动脉瓣疾病患者。Cor-Knot 器械（LSI Solutions）是一种自动紧固件，可固定瓣膜缝线。本病例报告介绍了 1 例微创主动脉瓣手术中心肌切开术后休克患者。发现患者主动脉根部夹层累及主动脉根部周长的 90%，包括双侧冠状动脉开口。尸检显示，器械轴远端的直接主动脉内膜撕裂可以解释主动脉损伤。由于肋骨之间的角度和空间受限，器械可能没有完全贴合缝合环。
