Abstract
Bleeding remains the most common complication following transcatheter aortic valve implantation (TAVI), despite a decline in its incidence over time. Periprocedural (≤30 days) major or life-threatening bleeding is reported to occur in 2.0-6.6% of patients undergoing TAVI. Major bleeding events carry a significant risk of mortality, with rates of 14.1% at 30 days and 27.8% at one year. The timely identification and management of patients at an elevated risk are therefore essential. Preventive measures include optimizing antithrombotic therapies, utilizing ultrasound-guided femoral access, employing single arterial access or a radial artery for secondary access, and administering unfractionated heparin under close monitoring. Long-term follow-up is essential for recognizing and managing late hemorrhages. In this review, we aimed to provide an in-depth analysis of bleeding events associated with TAVI and the most recent updates regarding the antithrombotic therapy of TAVI patients and its clinical impact.
