We describe two cases of worsening tricuspid regurgitation following surgical pericardiectomy for constrictive pericarditis. Both patients demonstrated hemodynamic profiles characteristic of constrictive pericarditis on cardiac catheterization. They also had moderate tricuspid regurgitation as judged by Doppler echocardiography. The worsening tricuspid regurgitation observed was a result of postoperative right ventricular dilatation. ...
Groves P H - - 1993
The development of late tricuspid regurgitation following mitral valve replacement is accompanied by a severe reduction in exercise capacity and a poor functional outcome. In this study, we compared the clinical and echocardiographic characteristics of two matched groups with (n = 13) and without (n = 13) clinically significant tricuspid ...
Guntheroth W G - - 1993
The prenatal diagnosis of pulmonary atresia is of particular importance because the affected neonate may be dependent on ductal blood flow to the lung, requiring urgent administration of prostaglandins. We review eight cases studied by ultrasonography in utero. Severe tricuspid regurgitation was present in six fetuses. Right ventricular size varied ...
Isobe M - - 1993
A 26-year-old man having chronic constrictive pericarditis with rare complications is described. Right ventricular inflow obstruction was caused by an intracavity giant mass which was surrounded by thick calcified pericardium. The mass consisted of old bloody fluid with some calcified tissue. The findings of auscultation closely mimicked those of tricuspid ...
Fantidis P - - 1993
A study of 31 dogs, divided into two groups, was conducted to compare direct atrioventricular with atriopulmonary connection using a valved conduit to treat tricuspid atresia. The first group (n = 9) acted as controls. In the second group (n = 22), an experimental model was established for direct atrioventricular ...
Knott-Craig C J - - 1993
The maximum cross-sectional area of the central pulmonary arteries indexed to the body surface area (pulmonary artery index [PAI]) was measured preoperatively from angiograms in 173 patients evaluated for a Fontan-type operation between 1981 and June 1989.

Tan J - - 1992
Assessment of cardiac dimensions of the chambers, great arteries and veins in the human fetus is important to distinguish abnormal dimensions from normal. This study establishes normal values based on cross-sectional echocardiographic measurements over the gestational period where these measurements may be clinically useful. Ventricular and atrial dimensions were measured ...
Cook D J - - 1992
Tricuspid valve stenosis in the setting of endocarditis is associated with a high morbidity. Diagnostic approaches incorporate a high clinical index of suspicion, echocardiographic evidence, and inferences about hemodynamic data derived from pulmonary artery catheterization. As demonstrated by the case presented herein, inadequate initial evaluation of right-sided pressures delayed the ...

Kitagawa H - - 1992
Cardiopulmonary function was examined in 18 dogs with serious chronic heartworm disease showing ascites, subcutaneous edema, prostration, weakness, jaundice and so on. After surgical heartworm removal from the pulmonary arteries, 10 dogs recovered (surviving group), and 8 dogs died or were euthanatized because of poor prognosis (nonsurviving group). The number ...
Buchs A E - - 1992
We have described a 28-year-old male sheepfarmer who had fever, headache, chills, malaise, and aortic insufficiency. Echocardiography revealed a tricuspid aortic valve with a large vegetation on the right cusp, an enlarged left ventricle, and diastolic flutter of the mitral valve. Repeated blood cultures were negative. Seroconversion of IgG and ...
Dorsa F B - - 1992
A case of accidental placement of a Greenfield filter in the right atrium is described. Transthoracic echocardiography demonstrated the filter but was unable to provide details regarding the exact location of the filter. Transesophageal echocardiography showed the filter to be fixed to the tricuspid anulus. This finding, which was confirmed ...
Heck H A HA - - 1992
An 18-year-old black woman presented with marginally compensated right heart failure, severe pulmonary hypertension, tricuspid incompetence, and right atrial myxoma. Catheterization suggested a substantial reactive component to her P-HTN, especially to nifedipine. Initial management consisted of excision of two right atrial myxomas and tricuspid annuloplasty, and postdischarge management with nifedipine, ...
Grant S C - - 1992
BACKGROUND: Carcinoid heart disease typically results in pulmonary stenosis and tricuspid incompetence. Percutaneous balloon dilatation is an effective treatment for congenital pulmonary stenosis and has been applied successfully to tricuspid stenosis caused by carcinoid heart disease. The value of balloon dilatation of the pulmonary valve in carcinoid pulmonary stenosis was ...

Heerdt P M - - 1992
We have been comparing cardiac output measured with a novel Doppler pulmonary artery catheter to that measured by thermodilution and aortic electromagnetometry in cardiac surgical patients. We report here our observation of a nearly twofold increase in thermodilution cardiac output after the acute intraoperative onset of tricuspid regurgitation that was ...
Naja I - - 1992
Tricuspid valvular insufficiency caused by blunt thoracic trauma may be clinically silent and imprecise. Diagnosis is often done by cardiac catheterization and two-dimensional echocardiography (2-DE); the latter may show abnormalities of the tricuspid leaflet motion. The surgical technique for its correction is still controversial. We report here the case of ...
Shaw T R - - 1992
The Inoue balloon was used for dilatation of tricuspid stenosis in a 74 year old woman. The valve was reached by an over-the-wire approach with a 0.025 exchange length guide wire. The Inoue stylet would not reach the tricuspid orifice because the right atrium was so large. The Inoue balloon's ...
Brecker S J - - 1992
We describe a simple, non-invasive and practical method to determine the peak velocity of tricuspid regurgitant flow (and hence derive systolic pulmonary artery pressure) from examination of the dynamics of retrograde tricuspid flow on Doppler. Based on a previously described relationship between right ventricular systolic pressure and the time interval ...
Himelman R B - - 1992
Exercise echocardiography is a versatile technique that includes not only two-dimensional imaging, but also Doppler of aortic, mitral, and tricuspid valves. Doppler echocardiography can be useful in the evaluation of global left ventricular systolic and diastolic function, valvular function, transvalvular gradients, and pulmonary artery pressure. The technique lends itself to ...

Pinto F J - - 1992
Patterns of systemic venous return change after cardiac surgery. However, the exact timing and underlying mechanisms are not well understood. To analyze these changes transesophageal echocardiography was used to evaluate 21 patients (mean age 56 +/- 17 years) during cardiac surgery. Eleven patients underwent coronary bypass grafting, 2 had ablation ...
Teyssier G - - 1992
Since the ovine model is the most commonly used for foetal haemodynamic investigation it was felt important 1) to investigate the technical difficulties involved with ultrasound fetal cardiac imaging in this species and 2) to establish normal reference values for ovine cardiac and umbilical blood flow velocity measurements. Both two-dimensional ...
Harpaz D - - 1992
We describe a 65-year-old patient with moderate combined mitral disease and severe tricuspid regurgitation, in whom the tricuspid regurgitant jet was oriented toward the interatrial septum. Color flow and pulsed Doppler demonstrated a late-systolic to mid-diastolic, right-to-left shunting of the tricuspid regurgitant jet through the foramen ovale. This finding was ...
Ames D E - - 1992
Clinical tricuspid stenosis has not previously been reported in patients with systemic lupus erythematosus (SLE). A 25 year old woman with active SLE presented with signs of severe right ventricular failure. Cardiac catheterisation confirmed the diagnosis of tricuspid stenosis and regurgitation together with mitral regurgitation. This patient underwent successful tricuspid ...
Mori K - - 1992
Nine cases of imperforate tricuspid valve associated with dysplasia of the right ventricular myocardium, pulmonary valve, and right coronary artery are described. The mean frontal QRS axis of the electrocardiograms did not indicate left axis deviation in seven of the nine. Two-dimensional echocardiograms showed an imperforate tricuspid valve, normally aligned ...
