Background: Conventional diagnostic algorithm in Heart Failure starts with 2D Echocardiography and ends with coronary angiogram in most patients. We decided to evaluate HF patients with MRI and correlate the findings with information available by other modalities Methods: We evaluated 500 patients of heart failure from various institutions with Magnetic resonance imaging. All patients underwent MRI at a single centre and all images were evaluated by a single operator (RJ). Cine imaging using segmented, breath-held steady-state free precession (SSFP) or real time pulse sequences; morphologic imaging using turbo spin-echo (TSE)-based sequences; perfusion imaging; inversion-recovery delayed-enhancement imaging; phase-contrast flow imaging were done. Findings: We evaluated 500 patients from 10 institutions referred by 13 cardiologists. 20 patients (4%) had constrictive pericarditis. 10 had cardiac tamponad due to localised pericardial collection of fluid. 30 patients (6%) isolated diastolic HF with restrictive physiology. The remaining 440 patients (88%) had systolic heart failure with LV dysfunction (EF<55%). The etiologydemonstrable by MRI were Ischemic 260 (52%) and non-ischemic 180(36%). The non-ischemic included HCM 60 (12%), ARVC/D 30(6%), myocarditis 30(6%), sarcoidosis 10(2%), EMF 10(2%), Non compaction 10(2%), amyloidosis 20(4%), indeterminate etiology 10(2%). The viability assessment with delayed hyperenhancement was useful in guiding revascularization in the ischemic subset. Conclusion: MRI evaluation in HF is a comprehensive single stop imaging option for assessment of cardiac anatomy, physiology, pathology and hemodynamics thus could guide appropriate therapies.
