Balloon- Versus Self-Expanding Intraannular TAVI in Small Aortic Annuli

Brief Summary

In Europe TAVI is now recommended for treatment of aortic valve stenosis from the age of 70 years. When performing TAVI in young patients, lifetime management becomes important in terms of anticipated TAVI-in-TAVI procedures when valve deterioration occures. Especially small aortic annuli represent a special challenge in terms of postprocedural hemodynamics, however intra-annular transcatheter heart valve designs should be the devices of choice to facilitate future TAVI-in-TAVI procedures. Which intra-annular valve design offers ideal clinical and hemodynamic efficacy is unclear. Therefore, an investigator-initiated, randomized controlled trial (BALANCE trial: Balloon- vs. Self-expanding intraannular TAVI in small aortic annuli) was created to elucidate this topic.
