The purpose of the study is to compare the various 2D and 3D methods of valvular heart disease quantification (Doppler, PISA, VCA, volumetric method) and strain with cardiac magnetic resonance (CMR) measurements of left and right ventricular systolic function strain and myocardial fibrosis assessment.
The objective of this study is to compare the accuracy of 3D TTE to 2D TTE in assessing the severity of valvular heart disease in patients with aortic stenosis, aortic regurgitation, and mitral valve regurgitation by comparing this to the reference standard of cardiac magnetic resonance (CMR) in subjects with different etiologies and mechanisms of valvular lesions and to the integrative method of valvular lesion grading as recommended by inter-societal guidelines. Another objective is to assess prevalence of focal and diffuse myocardial fibrosis as assessed by CMR in patients with aortic steno…
