Delayed Coronary Occlusion After Transcatheter Aortic Valve Implantation: Implications for New Transcatheter Heart Valve Design and Patient Management

Transcatheter aortic valve implantation (TAVI) has undoubtedly revolutionised the treatment of severe aortic stenosis and has become the preferred treatment option for patients at increased surgical risk.1,2 Although outcomes have improved and complications reduced over time, certain potentially catastrophic complications remain.3,4 Coronary obstruction has long been a feared complication and is classically recognised to occur in the acute setting just after valve deployment.

Coronary Revascularisation in Transcatheter Aortic Valve Implantation Candidates: Why, Who, When?

The prevalence of concomitant coronary artery disease (CAD) in patients with severe aortic stenosis (AS) varies widely among different reports. This depends primarily on the definition used to assess CAD as well as study design and patient selection, therefore making a uniform estimate difficult.

Diagnosis and Outcomes of Transcatheter Aortic Valve Implantation in Bicuspid Aortic Valve Stenosis

Bicuspid aortic valve is the most common congenital cardiac malformation, affecting 1.3 % of the population, and responsible for a significant proportion of aortic valve replacement in adults.1-3 Clinical presentation varies from severe valve disease in infancy to asymptomatic valve in old age, but symptoms typically develop in adulthood.

Delayed Coronary Obstruction After Transcatheter Aortic Valve Implantation is not the Structural Equivalent of Late Stent Thrombosis After Percutaneous Coronary Intervention

Reports of late stent thrombosis following percutaneous coronary intervention (PCI) with drug-eluting stents started to emerge in 2005 and 2006, causing widespread alarm and a substantial reduction in their use.1,2 Research-led advances in pharmacology and stent design have done much to allay this alarm, but nevertheless late stent thrombosis (LST) remains a concern for coronary interventionists and a focus for ongoing research.
