Abstract :

Patients with heart failure (LVEFâ�?¤30%) are clinically indicated for either an implantable cardioverter-defibrillators (ICD) or cardiac resynchronization therapy (CRT) device for prevention of sudden cardiac death. Those patients are at risk for cardiac events and may benefit from cardiac MRI to guide advanced therapy, including clinical decision making on: (i) whom and when for VT ablation or generator replacement, (ii) whom and when for myocardial recovery therapy such as left ventricular assist device. Despite that fact the cardiac MRI can be conducted safely in most patients with intracardiac device implantation, it is not performed routinely due to severe image artifacts associated with intracardiac devices. We have developed and implemented novel MRI methods that can suppress image artifacts induced by intracardiac devices and are able to produce diagnostically valuable images. These methods include late gadolinium enhanced (LGE, scar), first-pass myocardial perfusion, and cardiac T1 mapping (diffuse fibrosis) MRI methods. We present a novel approach to assess myocardial perfusion and fibrosis in patients who are traditionally not imaged with MRI. New imaging capability may be used to guide therapy in patients post intracardiac device implantation.
