[Interdisciplinary differential treatment of structural heart disease : When operation and when catheter-based intervention?].

The demographic changes in society lead to an increasing number of patients with aortic valve stenosis and mitral regurgitation. Simultaneously the higher age of patients is associated with an increase in multimorbidity with a high surgical risk so that they cannot be referred to surgery. Besides the current gold standard of surgery, minimally invasive therapeutic options are increasingly becoming established for these patients. For the differentiated indications and therapeutic success, a multidisciplinary heart team assumes an important role. The next generation of transcatheter aortic valve implantation (TAVI) systems will lead to improvement in the results, lower complication rates and mortality and as a result there is a general trend towards expanding the indications. New innovative minimally invasive mitral valve devices are still undergoing clinical trials and will define future therapy options.
