Comparison of Hemodynamic Performance of Transcatheter Aortic Valve Implantation With Supra-Annular Self-Expanding Versus Balloon-Expandable Valves Assessed by Exercise Cardiovascular Magnetic Resonance

Transcatheter aortic valve implantation (TAVI) has recently been approved for low surgical risk patients.1 Considering that such patients are more likely to engage in active lifestyles, achieving optimal hemodynamics may significantly impact their quality of life. Inclusion criteria were as follows:...

Description
Summary:Transcatheter aortic valve implantation (TAVI) has recently been approved for low surgical risk patients.1 Considering that such patients are more likely to engage in active lifestyles, achieving optimal hemodynamics may significantly impact their quality of life. Inclusion criteria were as follows: patients who underwent TAVI with SASEV or BEV had left ventricular ejection fraction ≥60%, estimated glomerular filtration rate >60 ml/min, sinus rhythm, and no significant coronary artery disease or permanent pacemaker. Patients were positioned on the magnetic resonance imaging scanner, and symptom-limited cardiopulmonary exercise tests (Parvo Medics, Sandy, Utah) were performed simultaneously using a standardized protocol.5 Scout images, followed by 2-dimensional real-time cine images with long-axis views (2-chamber, 3-chamber, and 4-chamber) and whole-heart short-axis coverage in addition to phase-contrast flow velocity mapping in the ascending aorta, were obtained at baseline.
