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...

conclusions there is a significant increased incidence of mortality, prolonged hospitalization, and rehospitalization in symptomatic patients with severe tr. therefore, we recommend more aggressive approach toward tv repair or replacement in these patients regardless of pap and systolic function. results heart failure (50%) was the most cause of death. mean years of survival from diagnosis of s...

Endomyocardial fibrosis is a common cause of heart failure in Uganda. A clinico-pathological study of this cardiopathy reported by Ball et al. (1954) established that the fibrotic process, while involving the endocardium of the apices of the ventricles, not infrequently extends to the chorda, tendinee and the cusps of the atrioventricular valves, tethering them down and producing atrioventricul...

Only 75% of severe tricuspid regurgitation is classified as functional, or related primarily to pulmonary hypertension, right ventricular dysfunction, or a combination of both. Non-functional tricuspid regurgitation occurs when there is damage to the tricuspid leaflets, chordae, papillary muscles, or annulus, independent of right ventricular dysfunction or pulmonary hypertension. The entities t...

OBJECTIVES This study examined the association between the presence of tricuspid regurgitation and immediate and late adverse outcomes in patients undergoing balloon mitral valvuloplasty. BACKGROUND Significant tricuspid regurgitation has an adverse impact on morbidity and mortality in patients undergoing mitral valve surgery for mitral stenosis. METHODS We studied 318 consecutive patients ...
