Clinical trials

This clinical investigation is being done to evaluate the safety and effectiveness of a new device, a PTV Balloon, that will be used to open up an area in the heart (the valve) before and potentially after placing a new valve in patients requiring a new heart valve. The main question it aims to answer is: What percentage of patients develop new heart conduction problems after using the investigational PTV Balloon for pre-dilatation? Participants will: 1. Undergo a TAVI procedure, where the PTV Balloon will be used for pre-dilatation and may also be used for post-dilatation. 2. Will be followed up until discharge or up to 7 days, whichever happens first.

This registry captures data on BioFreedomTM Ultra CoCr DCS in standard clinical practice (real world population) and serves as Post Market Clinical Follow up (PMCF) as part of the Post-Market Surveillance.

This study aims to demonstrate that the BioFreedom™ Ultra Drug Coated Stent (DCS) is non-inferior to the BioFreedom™ DCS, with respect to in-stent late lumen loss, and that it has safety characteristics similar to the BioFreedom™ DCS.
