Comparison of accuracy of mitral valve regurgitation volume determined by three-dimensional transesophageal echocardiography versus cardiac magnetic resonance imaging.

Direct planimetry of anatomic regurgitation orifice area (AROA) using 3-dimensional transesophageal echocardiography (TEE) has been described. This study sought to (1) compare mitral valve regurgitant volume (RV) derived by AROA using 3-dimensional TEE with RV obtained by cardiac magnetic resonance (CMR) imaging and (2) determine the impact of AROA and flow velocity changes throughout systole on the dynamic variation in mitral regurgitation. In 43 patients (71 ± 11 years old) with mild to severe mitral regurgitation, 3-dimensional TEE and CMR were performed.

Comparison of direct planimetry of mitral valve regurgitation orifice area by three-dimensional transesophageal echocardiography to effective regurgitant orifice area obtained by proximal flow convergence method and vena contracta area determined by color Doppler echocardiography.

Direct measurement of anatomic regurgitant orifice area (AROA) by 3-dimensional transesophageal echocardiography was evaluated for analysis of mitral regurgitation (MR) severity. In 72 patients (age 70.6 ± 13.

Follow-up results after interventional treatment of infarct-related saphenous vein graft occlusion.

Background: Acute occlusion of saphenous vein grafts resulting in acute coronary syndromes may be treated with interventional revascularization. Few data are available on intermediate and long-term results after revascularization of acute saphenous vein graft occlusion.

Methods: Fifty patients (67+/-10 years, 47 male) with troponin-positive acute coronary syndrome because of acute total or subtotal occlusion [thrombolysis in myocardial infarction (TIMI) flow 0=39, TIMI 1=8, TIMI 2=3] of one saphenous vein graft (12.
