Study to Collect CT and Heart Echo Imaging Data Before and After Transcatheter Aortic Valve Implantation TAVI to Predict Valve Performance

What this Trial Is About

Researchers are studying patients with severe aortic stenosis to find out if CT scans and heart echo scans taken before a Transcatheter Aortic Valve Implantation TAVI can help predict how well the new valve will work over time. This study focuses on collecting detailed imaging data before and after the TAVI procedure to improve predictions of valve performance using a computer program. Participants will have a CT scan before their TAVI procedure and another CT scan six months after the procedure, which is not normally done. The study involves using these scans along with routine measures to assess any changes or deterioration in the valve. Data collected will train an algorithm to predict TAVI valve outcomes. During the study, participants will undergo imaging tests including CT and transthoracic echo scans around the time of their TAVI and at six months follow-up. Researchers will monitor valve function and complications using these images and routine clinical measures. The main outcome is obtaining quality CT imaging data at six months, with additional assessments of valve function and heart health during follow-up. Participation lasts through the six-month post-TAVI period.
