ABSTRACT
Rheumatic heart disease is a very common cause of cardiovascular mortality and morbidity Doppler echocardiography has emerged as the primary way for assessing of valvular heart disease; either function or structure, myocardial dysfunction, and pulmonary hypertension. Recent reports have demonstrated that dynamic magnetic resonance imaging [MRI] may serve as an attractive, alternative or complement to echocardiography, This non-invasive technique provides three dimensional anatomic and functional data and a potentially more accurate measurement of ventricular function than is possible with echocardiography. The present study compares between echocardiography and MRI as diagnostic procedure for the diagnosis of rheumatic heart disease and its complications. Twenty four patients complaining of rheumatic heart diseases where diagnosed at Sayed Galal hospital during the period from May 2007 to April 2008 with ages ranging from 15 to 35 years undergo, history tacking, full clinical examination, ECG, echocardiography using Esaote XP-10 Biomedical corporation equipped with 2.5-5 transducer and CGE MRI Magnetom symphony 1.5 tesla[Siemens Medical system Erlangen Germany] at Mustafa Mahmoud Hospital and some private centers. Our study showed positive correlation between CMR and Echo as regard left ventricular volumes and function, mitral and aortic valve areas, pressure gradient across mitral valve, also positive correlation between [VEC] MRI and ECHO. regarding the severity of mitral and aortic regurgitation but no significant correlation were detected between [CGE] MRI and Echo regarding severity of mitral and aortic regurgitation. CMR is sensitive and specific method compared to Echo as regard estimation of left ventricular volume and function, mitral valve area, diastolic pressure gradient across mitral valve, aortic valve area and systolic pressure gradient across aortic valve, [VEC] MRI is more sensitive and specific than [CGE] MRI as regard measurement of severity of mitral and aortic regurgitation. We chose MRI rather than cardiac catheterization as a reference standard to avoid the invasive maneuver and radiation exposure of cardiac catheterization
