Abstract

Contrast two-dimensional and M-mode echocardiography were performed to determine the usefulness of contrast study for the diagnosis of tricuspid regurgitation. The study population consisted of 6 control cases without definite cardiac diseases and 30 patients with various cardiac diseases. The contrast echocardiography was completed in all cases. Back and forth movement of microbubbles across the tricuspid valve on apical four chamber view and/or right ventricular inflow tract view showed positive contrast sutdy in all patients. Systoic microcavitation in the inferior vena cava on subcostal view of M-mode and two-dimensional echocardiogram showed excellent in 25 patients out of 27 patients. M-mode contrast study out of 28 patients. Cardiac catheterization was performed in 11 patients and contrast echocardiographic evidence of tricuspid regurgitation was noticed in all patient. Increased right atrial pressure(more than 7mmHg) was noted in all patients. In 9 out of 11 patients, right ventricular systolic pressure was elevated (more than 40 mmHg). This findings suggested that the positive reults of contrast study may predict the alteration of hemodynamics of right-side heart in patients with various left-side heart diseases as well as with right-side heart diseases.
