Sažetak
MRI is a valuable tool in evaluation of valvular heart disease in patients with inadequate echocardiographic quality or discrepant results. It is the only technique capable of true in-vivo quantification of valvular regurgitation using phase-contrast imaging, therefore we can use it for accurate assessment of regurgitation severity. The severity of valvular stenosis can be estimated by planimetry of the valve opening or measurement of the peak antegrade velocity through the valve using phase-contrast imaging, but the MRI-measured peak velocity is usually underestimated due to partial volume averaging. Another advantage of MRI is the possibility to assess the impact of valvular disease on the cardiac chambers and large vessels, including atrial and ventricular volumes, systolic function and abnormalities of the ascending aorta and pulmonary arteries. As a reference standard for pulmonary valve assessment and evaluation of right ventricular volumes and function, MRI should be used for evaluation of patients with insufficiency of the tricuspid or pulmonary valves. Evaluation of myocardial fibrosis in patients with valvular disease has a prognostic impact, focal fibrosis can be assessed using late gadolinium enhancement, whereas diffuse interstitial fibrosis can be better evaluated using T1 mapping techniques and extracellular volume calculation.
