Investigation of the Safety and Performance of a Novel PTV Balloon in Patients Undergoing TAVI for Severe Aortic Stenosis
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.
• Symptomatic severe calcific stenosis of a native aortic valve with an AVA ≤1.0 cm2 (or AVA index ≤0.6 cm2/m2) AND mean aortic pressure gradient ≥ 40mmHg OR maximal transaortic velocity ≥4.0m/s OR Doppler velocity index ≤0.25 on site-reported echocardiography
• Local multi-disciplinary Heart Team agrees on indication and eligibility for TAVI
• Age ≥18 years
• Patient has signed the Patient Informed Consent Form
• Patient is willing and able to comply with requirements of the study
• Patients planned for trans-femoral procedure
