Prospective, multicenter registry in patients undergoing commercially available balloon expandable valve implantation. The registry will consist of 3 phases:
Prospective determination of baseline Status Quo (3 months):
Documentation of treatment pathways and endpoints of "routine" patients without educational program
Dedicated reflection and training (1 day):
One training session after the observational period to reflect on treatment pathways, exchange between valve coordinators involved, and develop improvements.
Implementation of tailored changes (2 months):
Implementation of the changes developed in the training.
Determination of the effect (3 months):
Coordinator measures optimization changes and determines effects.
