Transmyocardial Laser Revascularization and Cardiovascular Magnetic Resonance Imaging (Amsterdam)

September 4, 2013 updated by: Piedmont Healthcare

Effect of Transmyocardial Laser Revascularization on Myocardial Perfusion and Left Ventricular Structure by Cardiovascular Magnetic Resonance Imaging and Dynamic Volumetric Computed Tomography

The primary goal of this study is to better understand how Transmyocardial Laser Revascularization (TMR) affects the functioning of the heart and, in turn, relieves angina in individuals with coronary heart disease using Magnetic Resonance (MR) images and Computed Tomography (CT) images in some patients.
