The surgical management of functional tricuspid regurgitation is controversial. Functional tricuspid regurgitation is common in patients with aortic and mitral valve disease, particularly in the presence of pulmonary hypertension. The high incidence and reversibility of functional tricuspid regurgitation are due to the unique compliance of the thin right ventricular wall: modest increases in ri...

7. Clinical bottom line TV insufficiency should be treated during left-sided valve surgery when TR annulus is dilated (G21 mmym ;)70 mm 2 intra-operatively; G3.5 cm at trans-thoracic echocardio-graphy (TTE) w18x) regardless of the absolute grade of regurgitation, in cases of preoperative AF, trans-tricuspid PMK lead and underlying rheumatic disease. Also, 'ring' annuloplasty techniques should b...

"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...

This study aimed to explore the mechanism of membranous ventricular septal defect complicated with tricuspid regurgitation and the significance of ventricular septal defect occlusion by echocardiography. A total of 43 patients with membranous ventricular septal defect complicated with tricuspid regurgitation were observed by echocardiography and the changes in length, area and volume of tricusp...

Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...

The incidence and severity of catheter-induced tricuspid regurgitation has not been studied extensively. Given the frequency with which right heart catheters are employed to measure cardiac output, it is important to know whether the severity of catheter-induced tricuspid regurgitation is sufficient to invalidate the measurement of thermodilution cardiac output. Accordingly, the purpose of the ...

This paper describes a technique for treating severe tricuspid regurgitation due to severe tethering of the tricuspid valve leaflets. The anterior tricuspid leaflet is augmented by use of an autologous pericardial patch, which increases its size, and hence its surface area of coaptation, allowing increased leaflet coaptation to occur with reduced tension within the right ventricle. A Carpentier...

background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...

Objective: To define the entity of tricuspid regurgitation caused by tethering of the tricuspid valve leaflets by aberrant tendinous chords. Design: Retrospective study. Setting: Tertiary care centre (university teaching hospital). Patients: 10 patients with unexplained severe tricuspid regurgitation. Methods: The last 13 500 echocardiographic studies from our facility were reviewed to identify...

OBJECTIVE To determine the likelihood ratio for trisomy 21 in fetuses with tricuspid regurgitation at the 11 to 13 + 6-week scan. METHODS Fetal echocardiography was carried out by specialist pediatric cardiologists in 742 singleton pregnancies at 11 to 13 + 6 weeks' gestation and pulsed wave Doppler was used to ascertain the presence or absence of tricuspid regurgitation. To avoid confusion w...
