MIGRATION AND MISALIGNMENT OF MYVAL BALLOON EXPANDABLE VALVE DURING TRANSCATETHER AORTIC VALVE IMPLATATION.

Abstract

Introduction: Transcatheter aortic valve implantation (TAVI) is a treatment method for aortic stenosis with proven efficacy and recommended by professional societies in the cardiovascular field. Complications during TAVI are rare but important and potentially devastating, especially embolization or migration of prothesis.

Case presentation: We present a case of an 82-year-old patient in whom the prosthesis was displaced during implantation and later expanded in the descending aorta with a new prosthesis implanted in the aortic valve position.

Conclusion: Dislocation of the prosthesis during implantation is a serious complication. In most cases the prosthesis can be repositioned elsewhere in the aorta or perform a valve-in-valve procedure. In case of failure, the availability of cardiac surgery is important. Technological improvements, increasing operator experience and adequate periprocedural preparation minimize the risk of complications.
