Abstract
This article sought to conduct a comparative literature review between the transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) techniques, both used in the treatment of aortic stenosis (AE), relating the two techniques from the point of view of prognosis, morbidity and mortality. Aortic stenosis consists of the narrowing of this valve, it is a common condition caused by several etiologies, and it often evolves with left ventricular hypertrophy and function decreased. Currently, for the treatment of this pathology, there has been an increase in the use of TAVR, due not only to a technical-scientific advance that has made possible an optimization of the technique, but also as a result of the fact of having a lower incidence of complications. Although SAVR is still considered the gold standard treatment, TAVR is less invasive and is more suitable for patients at high surgical risk, in addition to presenting similar efficacy and safety to SAVR and better post-surgery prognosis. However, it is essential to analyze other variables such as risk, benefit and comorbidities of the patient before opting for the best treatment technique.
