Abstract
Objective: To make clear the efficacy of transcatheter aortic valve implantation (TAVI) in the treatment of aortic valve stenosis by reviewing the clinical evidence, comparing it with conventional surgical treatment, and highlighting the limits, complications, and value for money from an analysis of the current scientific production on the subject. Bibliographic review: Aortic stenosis (AS) is a common disease of the cardiovascular system that can lead to progressive deterioration of the left ventricle. In many cases, surgical intervention is necessary in an effort to guarantee the patient's survival. Among the available techniques, TAVI, when compared to conventional surgery, ensures larger valve areas with better hemodynamic performance, reduces the surgical time and postoperative recovery, and also proved to be superior in relation to the incidence of some complications. Therefore, TAVI is considered the gold standard technique for high-risk patients and an option for medium and low risk. Final considerations: TAVI has benefits in the treatment of AS, especially in severe patients in which conventional surgery is contraindicated. However, the cost, lack of medical knowledge about the technique and adequate hospital structure may be limiting factors in our country.
