[Interventional therapy of heart valve diseases: future perspectives]

Transcatheter procedures have been adopted as novel treatment strategy for patients with valvular heart disease, particularly for those who are inoperable or at high risk for surgical valve procedures. Significant technological advances have resulted in an improvement of devices for transcatheter aortic valve replacement (TAVI) with downsizing of crossing profiles, reduction in the rate of paravalvular leakage and conduction abnormalities as well as a lower short- and mid-term mortality and a higher patient acceptance. In the near future, TAVI may potentially develop as first-line treatment for the majority of patients with aortic valve disease. For patients with mitral and pulmonary stenosis, balloon valvuloplasty is effective and well established and should be preferred over valve replacement, last but not least also for economic reasons. For treatment of mitral regurgitation, several transcatheter devices aiming to restore or replace mitral valve function are currently under investigation. This review summarizes the current state of interventional treatment of valvular heart disease along with implications for the future.
