The hypothesis is that SEV result in superior valvular hemodynamics (more pronounced during exercise) and exercise capacity relative to BEV. Furthermore, the hypothesis is that stress CMR will be able to demonstrate differences in these hemodynamic parameters. CMR will also provide refined assessment of paravalvular leak and its impact on ventricular function and on clinical outcomes.A teljes eredeti leírásKevesebb
Comparison of Hemodynamic Performance of Transcatheter Aortic Valve Replacement With Supra-Annular Self-Expanding Versus Balloon-Expandable Valves Assessed by Exercise Cardiovascular Magnetic Resonance
The hypothesis is that SEV result in superior valvular hemodynamics (more pronounced during exercise) and exercise capacity relative to BEV. Furthermore, the hypothesis is that stress CMR will be able to demonstrate differences in these hemodynamic parameters. CMR will also provide refined assessment of paravalvular leak and its impact on ventricular function and on clinical outcomes.
Bevonási feltételek: Aortic valve stenosis with clinical indication for valve replacement decided by a dedicated heart team; Planned transfemoral TAVR; 18 years of age or older; Able to give informed consent.
Kizáró feltételek: Patients with non-MRI safe implants; Arrhythmia which would prevent adequate cardiac gating, including atrial fibrillation; History of surgical aortic valve replacement or patients who undergo a valve-in-valve TAVR procedures; Significant non-treated coronary artery disease; Patients with permanent pacemakers or implantable defibrillators; Severe claustrophobia; Inability or contraindication to perform exercise bike stress test; Reduced left ventricular systolic function (<40%).
