Predictive Factors, Management, and Clinical Outcomes of Coronary Obstruction Following Transcatheter Aortic Valve Implantation: Insights From a Large Multicenter Registry
In this manuscript, the authors review 44 cases of coronary artery obstruction following TAVI from a registry of 6688 patients. This complication is rare but life threatening. A number of variables such as older age, female gender, previous CABG, the use of balloon expandable prosthesis, previous surgical bioprosthesis, left coronary ostia height, and sinus of Valsalva diameter appear to be related to this complication.
