Why the study?
Does whole-heart magnetic resonance imaging using slow infusion of Gd-BOPTA allow for simultaneous visualization of venous anatomy and myocardial scar in a single exam?
Does whole-heart magnetic resonance imaging using slow infusion of Gd-BOPTA allow for simultaneous visualization of venous anatomy and myocardial scar in a single exam?
The study proposes a novel CMR protocol using slow infusion of Gd-BOPTA to simultaneously visualize coronary venous anatomy and myocardial scar for optimal CRT planning.
For cardiac resynchronization therapy (CRT), knowledge of the coronary venous anatomy in relation to areas of myocardial scar is important to plan the optimal LV lead position during the CRT-procedure. Cardiac magnetic resonance imaging (CMR) has previously been used to assess coronary veins without a contrast agent (CA) using MTC-prepulse or injecting an intravascular CA. However, neither of these methods provide information about myocardial scar.
