Abstrakt: Transesophageal echocardiography (TEE) was performed within 24 hours after cardiac catheterization in 45 patients for assessment of native mitral valvular regurgitation. Color flow mapping was used in evaluating systolic regurgitant jet sizes. A jet demonstrated by TEE was 96% sensitive and 44% specific for angiographic mitral regurgitation. The presenceof angiographic mitral regurgitation was best predicted by (single measurement) (1) a holosystolic jet, (2) a jet length >2.5 cm, and (3) a jet area >2 cm2. Severeangiographic mitral regurgitation (grades 3 and 4) was best predicted by (single measurement) (1) a jet area >5 cm2, and (2) a jet length >4 cm. It is concluded that the assessment of angiographic mitral regurgitation by TEE is improved by the measurement of these jet parameters, which have a high sensitivity and higher specificity than the presence of a jet alone. Furthermore, with TEE one is able to differentiate severe (grades 3 and 4) from absent or mild mitral regurgitation (grades 0, 1, and 2).
