Transcatheter aortic valve implantation in patients with bicuspid aortic valve (literature review)

Transcatheter aortic valve implantation (TAVI) is a technology that allows effective surgical treatment for aortic valve stenosis. One of the causes of aortic stenosis is a congenital pathology characterized by a bicuspidal structure of the aortic valve. This condition has long been considered an absolute contraindication to TAVI, however, the emergence of new generations of prostheses, surgical experience, as well as a deep understanding of the anatomy of bicuspid valves allows to perform TAVI in such patients. This article discusses the existing classifications of bicuspid aortic valves, the features of preoperative preparation, and also presents the results of existing studies of TAVI in patients with bicuspid morphology.
