AIMS: Transcatheter aortic valve implantation (TAVI) is becoming a safe and effective technique for treating symptomatic aortic valvular stenosis (AVS) as an alternative to surgery in very high-risk patients. A possible consequence of valve implantation is the obstruction of coronary ostia. METHODS AND RESULTS: Here we report five cases of angiographically confirmed left main (LM) obstruction, occurred immediately after balloon expandable aortic valve implantations at our institution. In four of these cases, LM obstruction was resolved with an emergency percutaneous coronary intervention (PCI). In the remaining case, obstruction transiently occurred only at the time of balloon valvuloplasty and did not required treatment. During this type of intervention, performing an aortography at the time of balloon valvuloplasty could help to identify patients at risk for coronary obstructions. CONCLUSIONS: These cases illustrate that obstruction of the coronary ostia following TAVI is a possible complication. As the use of TAVI becomes widespread, the operators should be aware of this dangerous complication in their case preparation should it arise. |
