TAVR Mechanical Complications Prevention and Management

Transcatheter aortic valve replacement (TAVR) is now considered a treatment option for most patients with aortic stenosis, irrespective of surgical risk. Despite increasing operator experience with TAVR in high- and low-risk patients and overall refinement of all aspects of the procedure, there continue to be occasional complications associated with significant morbidity and mortality. Of these, mechanical complications including annular rupture, perforation and tamponade, bioprosthetic valve infolding, and valve embolization are some of the most significant and have not significantly declined over time. In this chapter, we provide an overview of these complications and steps we can take to avoid them.
