Transcatheter Aortic Valve Replacement Technique and Current Approaches

Abstract

Aortic stenosis (AS) is a chronic, progressive disease. The most common cause of aortic stenosis etiology in advanced age is calcific, degenerative aortic stenosis. Once patients become symptomatic, the disease progresses rapidly. Treatment is surgical aortic replacement. Advanced age and the presence of comorbid conditions increase the risk of surgery. Therefore, a significant number of patients cannot be treated. For this purpose, transcatheter aortic valve interventions were developed and started to be used all over the world. In this article, we discussed the technical features of the transcatheter aortic valve replacement (TAVR) procedure, the types of valves used and the complications of the procedure. Clinical results of the procedure and comparisons with other treatment methods will not be included in our article.
