International Circulation:   Could you talk about some of the complications that are associated with TAVI?
国际循环：您能谈谈与TAVI有关的并发症吗？

Prof. Greg W. Stone:  Complications have most commonly been vascular complications， everything from bleeding， infection， iliac artery avulsion or perforation.  Just because of the size of the devices the complications that could occur include arrhythmias like bradycardia or heart block.  Especially with the core valve device it has been more common to require permanent pacemakers.  Stroke can occur， as well as myocardial infarction， and coronary artery compression， embolization， or closure.  The valve can occasionally embolize and have to be extracted， either surgically or percutaneously， or have to be implanted into the aorta.  Mortality is a complication that is not trivial.  Pretty much any complication that can occur， aortic dissection is another， has occurred.  After all these are very high-risk patients to begin with.
 Prof. Greg W. Stone:  最常见的并发症是血管并发症，所有发生于出血，感染，髂内动脉撕裂或穿孔的事件。仅仅因为装置大小的并发症包括心律失常如心动过缓或心脏传导阻滞。特别是核心瓣膜装置，尤其需要永久起搏器。此外，也可发生中风，以及心肌梗死和冠状动脉压缩，栓塞，或者关闭。瓣膜偶尔也可发生栓塞<
