Catheter-Based Endomyocardial Injection With Real-Time Magnetic Resonance Imaging
2002
Circulation
Background-We tested the feasibility of targeted left ventricular (LV) mural injection using real-time MRI (rtMRI). Methods and Results -A 1.5T MRI scanner was customized with a fast reconstruction engine, transfemoral guiding catheter-receiver coil (GCC), MRI-compatible needle, and tableside consoles. Commercial real-time imaging software was customized to facilitate catheter navigation and visualization of injections at 4 completely refreshed frames per second. The aorta was traversed and the
