Diagnosis of tricuspid regurgitation by contrast echocardiography.
Sixty-two subjects underwent M-mode and two-dimensional echocardiographic studies that included imaging of the inferior vena cava (IVC) during upper extremity contrast injections. Group 1 consisted of 10 patients with clinical tricuspid regurgitation (TR). Group 2 consisted of 40 patients without definite clinical signs of TR but with conditions known to be commonly associated with TR (e.g., mi...
متن کامل3D echocardiography for traumatic tricuspid regurgitation.
T H E T R I C U S P I D V A L V E ( T V ) I S A C O M P L E X S T R U C T U R E . Unlike mitral and aortic valves, simultaneous visualization of the 3 TV leaflets cannot be achieved with 2-dimensional echocardiography (2DE) due to valve orientation with reference to the imaging planes. No 2D echo plane is parallel to the tricuspid valve. Therefore, there is no short-axis view for the tricuspid ...
متن کاملQuantitative assessment of tricuspid regurgitation using pulsed Doppler echocardiography.
Tricuspid valve regurgitation was assessed quantitatively by measuring blood flow velocity in the vena cava using a pulsed Doppler velocimeter. A non-invasive index of regurgitation was obtained by calculating the ratio between the maximum amplitudes of the systolic and diastolic components of the velocity curves. The index was compared with the angiographic grading of regurgitation in 70 patie...
متن کاملDetection of tricuspid regurgitation with two-dimensional echocardiography and peripheral vein injections.
"Contrast echocardiography", utilizing a two-dimensional ultrasound system and peripheral venous injections, was used for the detection of tricuspid regurgitation in 30 patients. The appearance of contrast in the inferior vena cava and the back and forth movement of contrast across the tricuspid valve were considered evidence for tricuspid regurgitation. Echocardiographic findings were correlat...
متن کاملClinical utility of 3-dimensional echocardiography in the evaluation of tricuspid regurgitation caused by pacemaker leads.
BACKGROUND This study evaluated the usefulness of 3-dimensional echocardiography (3-DE) for identifying permanent pacemaker (PPM) or implantable cardioverter defibrillator (ICD) lead-related symptomatic tricuspid regurgitation (TR). METHODS AND RESULTS Eighty-seven patients underwent 3-DE examination: 50 patients with PPM, 17 with ICD, and 20 with cardiac resynchronization therapy devices. TR...
