In recent years increasing number of mitral bioprosthesis implantation, especially in elderly population, is observed. Bioprosthetic valves are associated with a lower risk of thrombotic and bleeding adverse events compared with mechanical prostheses, but their use is limited due to their durability. After years numerous patients may develop bioprosthesis failure, requiring valve reintervention. Significantly burdened ones are oftentimes disqualified or not referred to surgery redo. An emerging treatment method for these patients is transcatheter mitral valve-in-valve implantation as an alternative to re-operation. This technique is applied with the use of devices previously dedicated to transcatheter aortic valve implantation (TAVI). Recent papers prove that transcatheter mitral valve replacement (TMVR) is a safe and effective procedure when performed in a selected group of high-surgical-risk patients. However, data regarding the Polish population are limited. Therefore, the aim of the study is to create a nationwide registry, collecting data from all Polish centers performing TMVR in order to describe the population of patients developing mitral bioprosthesis failure, evaluate their follow-up after TMVR as well as results of the transcatheter valvular intervention and identify potential limitations of the procedure.
