Assessment of mitral bioprostheses using cardiovascular magnetic resonance
BACKGROUND The orifice area of mitral bioprostheses provides important information regarding their hemodynamic performance. It is usually calculated by transthoracic echocardiography (TTE), however, accurate and reproducible determination may be challenging. Cardiovascular magnetic resonance (CMR) has been proven as an accurate alternative for assessing aortic bioprostheses. However, whether CM...
متن کاملTowards comprehensive assessment of mitral regurgitation using cardiovascular magnetic resonance
Cardiovascular magnetic resonance (CMR) is increasingly used to assess patients with mitral regurgitation. Its advantages include quantitative determination of ventricular volumes and function and the mitral regurgitant fraction, and in ischemic mitral regurgitation, regional myocardial function and viability. In addition to these, identification of leaflet prolapse or restriction is necessary ...
متن کاملThree-dimensional dynamic assessment of tricuspid and mitral annuli using cardiovascular magnetic resonance.
AIMS To explore the potentiality of cardiovascular magnetic resonance (CMR) in the quantitative evaluation of mitral valve annulus (MVA) and tricuspid valve annulus (TVA) morphology and dynamics. METHODS AND RESULTS CMR was performed in 13 normal subjects and 9 patients with mitral (n = 7) or tricuspid regurgitation (n = 2), acquiring cine-images in 18 radial long-axis planes passing through ...
متن کاملCardiovascular magnetic resonance of mitral valve length in hypertrophic cardiomyopathy
BACKGROUND Previous data suggest that mitral valve leaflets are elongated in hypertrophic cardiomyopathy (HCM), and mitral valve leaflet elongation may constitute a primary phenotypic expression of HCM. Our objective was to measure the length of mitral valve leaflets by cardiovascular magnetic resonance (CMR) in subjects with HCM caused by a Finnish founder mutation in the myosin-binding protei...
متن کاملCardiovascular magnetic resonance characterization of mitral valve prolapse.
OBJECTIVES This study sought to develop cardiovascular magnetic resonance (CMR) diagnostic criteria for mitral valve prolapse (MVP) using echocardiography as the gold standard and to characterize MVP using cine CMR and late gadolinium enhancement (LGE)-CMR. BACKGROUND Mitral valve prolapse is a common valvular heart disease with significant complications. Cardiovascular magnetic resonance is ...
