Since the first transcatheter aortic valve implantation (TAVI) in 2002, the paradigm for the treatment of severe aortic stenosis has changed. In the recent past, medical therapy with or without balloon aortic valvuloplasty was the only option for inoperable patients but now, TAVI has become the treatment of choice for these patients and the preferred alternative for high-risk operable patients. Surgical aortic valve replacement (SAVR) currently remains the gold standard for patients at low operative risk. As randomized trials have demonstrated comparable (or better results with TAVI) between TAVI and SAVR in the high-risk population, there is now a clear trend towards performing TAVI even in intermediate-risk. Nevertheless, there are still questions regarding TAVI involving paravalvular leak, stroke, pacemaker requirements, and durability, which remain to be more definitively answered before TAVI can routinely be performed in lower risk and younger population. Improvements in patient selection, multimodal imaging, and third generation devices have significantly decreased the incidence of TAVI complications. A role for post-procedure antithrombotic or anticoagulant management remains unanswered. Waiting for current studies to provide us with clear answers to these questions, it is the Heart Team's task to determine the optimal treatment for each patient based on risk scores, frailty metrics, comorbidities, patient's preference, and potential for improvement in quality of life.
