Abstract

Background: Cardiac magnetic resonance (CMR) is highly efficient imaging tool to detect types of heart disease. Recently, valvular heart disease (VHD) are increasing due to aging population, so CMR is very useful in assessment of all heart valves



Objectives: This study aims to asses VHD and its severity by CMR to establish clinical protocol for our unit.

Subjects and methods: This a single center cross sectional study included 24 patients (19 males and 5 females) their ages range from 1 to 74 years. Included patients who suffer VHD according to the clinical susceptibility and Echo results. CMR protocol: localizers, short axis cine ,2 chambers cine, 3 chambers cine , 4 chambers cine, LVOT, RVOT, Q flow aorta /pulmonary, Q flow mitral /tricuspid, LGE in selected cases .

Results: Concerning Aortic valve, cMRI detected 10 cases out of 24 (41 %) showed aortic valvular lesion while echo detected only 2 cases of them (8 %). Concerning Mitral valve, cMRI detected 15 cases out of 24 (62 %) showed mitral valvular lesion while echo detected only 11 cases of them (46 %).



Conclusion: CMR is an efficient technique in the evaluation of VHD because it provides major additional value, such as the capacity to image all parts of the heart and a complete approach to both valve lesion and ventricle. Direct measurement of valve stenosis, measurement of regurgitation, aortic and pulmonary flows, precise ventricular volumes, and myocardial evaluation are all part of this.
