Abstract
Cardiovascular medicine at its beginning was dominated by surgical treatment options. The trend of the last decades is heading towards catheterization procedures.
Alcohol septal ablation (ASA) was published by Sigwart in 1995 whereas transcatheter aortic valve implantation (TAVI) was performed in 2002 for the first time. Both methods have become efficient therapeutic options not only for patients not suitable for surgery but also for low-risk patients.
Although the procedures are widely performed, certain challenges remain. Moreover, as patients get older, new difficulties emerge.
We present a case of a patient with hypertrophic obstructive cardiomyopathy (HOCM) that was treated by ASA. Fifteen years later the patient developed severe aortic stenosis and was treated by TAVI that became severely stenotic 5 years later and required TAVI-in-TAVI implantation.
