Role of Cardiac MRI in assessment Non-Ischemic Cardiomyopathy

Abstract

Background: cardiomyopathies encompass a broad spectrum of myocardial conditions which can affect the heart as a primary disease process or as part of a systemic disorder, evolving toward heart failure or cardiovascular death. Objective: this study aimed to identify the role and diagnostic potential of cardiac magnetic resonance imaging to diagnose and differentiate various types of cardiomyopathy. Patients and Methods: this study included 50 patients with suspected different types of non-ischemic cardiomyopathies referred from outpatient clinic of Cardiology at Al-Hussein University hospital from November 2018 to July 2019. Results: all patients showed mild to moderate mitral regurge (100% of cases), tricuspid regurge was seen in 3 cases (75% of cases) and aortic regurge was seen in 4 cases (50 % of cases). The most value of MRI study of these patients was to differentiate whether if heart failure is related to 1ry dilated cardiomyopathy or other causes such as ischemia as they have different management in each group. Conclusion: CMR is a valuable (minimally or non-invasive) imaging technique in patients with suspected or known to have non-ischemic cardiomyopathies. It helps to identify the underlying cause, predict prognosis and responsiveness to therapy and affect management as well follow-up and most recently as primary prevention diagnostic tool.
