Transcatheter structural heart interventions have drastically evolved over the past 2 decades. However, most catheterization procedures require the deployment of devices in the body; therefore, the adhesion of thrombi to those devices is a major problem, resulting in the requirement of a period of postprocedural antithrombotic regimen. However, in recent years, bleeding associated with these antithrombotic therapies has also become a major concern, attracting the attention of investigators. This is complicated by the fact that patients at high thrombotic risk are also at high bleeding risk, making the issue of administrating antithrombotic therapy challenging. The objective of this review was to identify the important issues and summarize the current status of postoperative antithrombotic therapy and assessment of the bleeding risk following transcatheter structural heart interventions such as transcatheter aortic valve replacement, transcatheter edge-to-edge repair, and transcatheter left atrial appendage occlusion.
Keywords: antithrombotic therapy; bleeding risk; transcatheter aortic valve replacement; transcatheter edge-to-edge repair; transcatheter structural heart interventions.
