Predictive Factors, Management and Clinical Outcomes of Coronary Obstruction Following Transcatheter Aortic Valve Implantation: Insights from a Large Multicenter Registry

A multicenter TAVI registry that included nearly 6,700 patients identified 44 who suffered coronary obstruction following TAVI.  This complication was associated with older age, female sex, no prior CABG, and use of a balloon-expandable valve.  30-day mortality was 41%.  The left coronary artery was most commonly affected, and patients were at increased risk who had lower mean ostial height and smaller sinus diameters.
