Overview
Cardiac magnetic resonance(CMR) is a gold standard for assessment of morphology of the pulmonary valve, for quantification of the severity of the regurgitation and the RV systolic function. CMR is useful in quantification of the regurgitant volume and regurgitant fraction of PR by using sequences called “velocity- encoded phase-contrast images”.[1] CMR is useful for evaluating pulmonary regurgitant fraction, RV end-diastolic and end- systolic volumes, and RV ejection fraction. CMR is the diagnostic modality preffered to determine the requirement of re-intervention in patients with repaired tetralogy of Fallot and to assess the ventricular function and dimensions.

CMR may be used for assessing individuals with valvular heart disease in which evaluation of valvular stenosis, regurgitation, para- or perivalvular masses, perivalvular complications of infectious processes, or prosthetic valve disease are needed. CMR may be useful in identifying serial changes in LV volumes or mass in patients with valvular dysfunction. |
