We report a patient who developed ascending aorta dissection after aortic valve replacement with a Perceval sutureless pericardial bioprosthesis, a previously not reported complication with this device. At reoperation, the intimal tear was located at the aortotomy suture line; the tips of the nitinol stent were far from the aortic lesion which therefore was not attributable to the presence of this specific prosthetic model. Nevertheless, a previous report of aortic dissection due to erosion of the aortic wall by the strut of a transcatheter prosthesis may raise the suspicion that such complication could also occur with sutureless prostheses of similar design.
我们报告了一例患者,其在使用Perceval无缝线心包生物瓣膜进行主动脉瓣置换术后发生升主动脉夹层,这是该装置此前未报告过的并发症。再次手术时,内膜撕裂位于主动脉切开缝合线处;镍钛诺支架的尖端远离主动脉病变,因此该病变并非归因于这种特定假体模型的存在。然而,此前有关于经导管假体支柱侵蚀主动脉壁导致主动脉夹层的报告,这可能会引发怀疑,即类似设计的无缝线假体也可能发生此类并发症。
