Current research status and research progress of complications after transcatheter aortic valve replacement

Over the past decade, with the introduction of transcatheter aortic valve replacement(TAVR) into clinical practice, the treatment of aortic stenosis has changed dramatically. As a supplement to surgical aortic valve replacement surgery, TAVR is mainly used for the treatment of patients with old age, severe aortic stenosis, left heart failure, and high surgical mortality risk who cannot undergo SAVR. However, with the development of TAVR, the postoperative complications have become more prominent. As a minimally invasive interventional surgery, full understanding and proper handling of TAVR related complications is an essential requirement for developing TAVR. This article mainly reviews the current research status and research progress of the related complications after TAVR.
