Three-dimensional echocardiography for quantitative analysis of XXXX .

@entity1 @entity583 @entity439 @entity1002
BACKGROUND: Quantitative analysis of left-ventricular (LV) @entity439 after @entity583 is prognostically relevant and assists in planning surgery. Three-dimensional (3D) echocardiography facilitates clear visualization of cardiac anatomy and accurate assessment of functional parameters. The aim of the present study was to determine the ability of 3D echocardiography to quantify LV @entity439 . METHODS: Ten @entity1 with a known @entity1002 after @entity583 underwent 3D echocardiography and cardiac magnetic resonance (CMR) imaging at 1.5 Tesla within 3 days. For 3D echocardiography, a multiplanar transesophageal examination was performed with full LV coverage and the 3D dataset was analyzed offline. The @entity1002 was defined by a wall thickness <5 mm. The following quantitative parameters were determined: left ventricular end-diastolic and end-systolic volumes, LV myocardial mass (LV-mass) and mass of the @entity1002 . LV ejection fraction and percentage of @entity439 mass (%- @entity439 ) were calculated. RESULTS: LV volumes and ejection fraction showed a strong correlation between 3D echocardiography and CMR (r = 0.94-0.97; P < 0.01). Importantly, the mass and percentage of mass of the @entity1002 demonstrated a high correlation as well (r = 0.94 and r = 0.86, respectively; P < 0.01). For all parameters, the calculated bias between both methods was found to be minimal (0.8-7.6%). CONCLUSIONS: Three-dimensional echocardiography proved to be a reliable tool for quantitative analysis of LV volumes, ejection fraction and @entity439 size in @entity1 with prior @entity583 . In addition, 3D visualization of the complex cardiac anatomy in @entity1 with @entity1002 may assist surgical procedure planning.
