Introduction Transcatheter aortic valve implantation (TAVI) is now the standard treatment for older adults with symptomatic severe stenosis of a trileaflet aortic valve regardless of surgical risk who do not warrant a mechanical valve. A key component in case planning…
Key features of transcatheter valves In transcatheter aortic valve implantation (TAVI), the selection of the best suited transcatheter aortic valve (TAV) for each individual patient remains a challenge. The ideal bioprosthetic transcatheter valve would have all of the following features:…
Coronary artery disease Prevalence and clinical impact In randomized clinical trials, more than two-thirds of intermediate- and high-risk transcatheter aortic valve implantation (TAVI) candidates have coronary artery disease (CAD). , The impact of CAD on long-term outcomes after TAVI is…
Introduction The importance of precise preprocedural multimodality imaging with echocardiography and cardiac multislice computed tomography (MSCT) before transcatheter aortic valve implantation (TAVI) cannot be overemphasized. Both echocardiography and MSCT imaging are the foundations of quality outcomes in TAVI and are…
Introduction The following prerequisites are essential before patient selection in transcatheter aortic valve intervention (TAVI): 1. An accurate diagnosis of severe aortic stenosis (AS) 2. An indication for aortic valve intervention (i.e., severe symptomatic AS) 3. A constellation of clinical,…
TAVI center structure General principles An effective system for the evaluation and management of patients with severe aortic stenosis (AS) requires a multilevel, graduated approach to identify patients with disease and refer them for therapy in a timely and efficient…
Indications for aortic valve intervention Aortic stenosis (AS) is the most common heart valve disease that is associated with increased cardiovascular mortality and requires intervention. The prevalence increases with age, and currently 1 in 20 people age 75 and older…
