| Popis: | Cardiac resynchronization therapy (CRT) is a contemporary and established treatment for patients with symptomatic heart failure, severely impaired left ventricular (LV) systolic dysfunction and a wide (>150 ms) complex. As with any other treatment, the response to CRT is variable. The degree of preimplant scar burden and scar localization to the vicinity of the LV pacing stimulus are known to influence response and outcome. As well as providing measurements of global and segmental cardiac function, coronary venograghy, CMR also permits localization and quantification of myocardial perfusion and scars. This review explores on the role of CMR in the assessment of patients undergoing CRT, with emphasis on risk stratification and RV and LV leads deployment. |
