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 کاملMitral and tricuspid annular endocarditis. Diagnosis by transesophageal echocardiography.
Two cases of infective endocarditis with vegetations attached to the mitral and tricuspid annuli are described. In both cases, the vegetations could not be identified by transthoracic echocardiography. These cases illustrate the advantage of TEE over the transthoracic approach in recognizing vegetations in extravalvular locations.
متن کاملEchocardiography of the Tricuspid Valve
Two patients, ages 14 and 18, with congenital left ventricular-right atrial communication through a defect in the tricuspid valve were studied by echocardiography. Proof was obtained by angiocardiography and surgery in one and ultrasonic contrast injection and angiocardiography in the other. Both presented clinically as uncomplicated ventricular septal defects. Echocardiography consistently dem...
متن کاملMitral and Tricuspid Valve Closure
Echocardiography was used to evaluate mitral and tricuspid valve closure in patients 1 day to 20 years of age. When possible, simultaneous phonocardiograms were obtained. The difference in time between the Q wave of the electrocardiogram and mitral closure and between Q and tricuspid closure was designated the delta value (A). Four groups of patients were assessed: 1) normals (40), secundum atr...
متن کاملFunctional maturity of tricuspid and mitral valves in school children evaluated by echocardiography.
T he prevalence of valve regurgitation in healthy people has been previously examined by echocardiography. Pulmonary regurgitation or tricuspid regurgitation (TR) was common, mitral regurgitation (MR) was less common, and aortic regurgitation was generally undetectable. In addition, the prevalence of regurgitant signals varies with age or sex. Assuming that a low prevalence of regurgitant signa...
