A Novel Technique for Prosthetic Valve Retrieval After Transcatheter Aortic Valve Embolization.

Although the rate of procedural complications during transcatheter aortic valve implantation has decreased because of technological advancement and increased operator experience, device embolization remains a rare but potentially fatal complication, even with new generation devices. We report, to our knowledge, the first case of Portico valve (St Jude Medical, Minneapolis, MN) migration despite apparent optimal initial implantation depth, which was retrieved using a novel strategy after failure of a traditional retrieval technique. We also describe a mechanism of left coronary artery systolic perfusion with diastolic backflow, which led to myocardial ischemia.
