Tricuspid valve myxoma: a rare indication for tricuspid valve repair.

Excision of a myxoma involving the tricuspid valve often necessitates tricuspid valve replacement or a less than optimal margin of resection. We report a successful tricuspid valve repair after en bloc resection of a myxoma involving the septal leaflet of the tricuspid valve.

[Supraannular implantation of bioprosthetic valve for severe tricuspid valve regurgitation associated with atrial septal defect in an adult patient].

With an adult atrial septal defect, there was often regurgitation of the mitral and tricuspid valve due to volume overload in a long term period. Especially concerning tricuspid regurgitation, what can be done surgically has not yet been decided. For severe tricuspid regurgitation, some cases where tricuspid valve annuloplasty were performed have had exacerbation of tricuspid regurgitation. We experienced a case where tricuspid valve supraanular implantation without excision of native tricuspid valve (TVSI) was performed for severe tricuspid regurgitation associated with atrial septal defect, and improved. A 53-year-old female complained of dyspnea on exertion. An atrial septal defect was revealed being 4 cm in size, complicated with severe tricuspid regurgitation (IV), and 62 mmHg difference of pressure from the right atrium to right ventricle shown by a ultrasonography. Pulmonary artery pressure was 66/16 mmHg by cardiac catheter. Patch closure for ASD and TVSI for TR was performed on her, and amelioration of cardiac function was recognized.

Laser-assisted tricuspid valve balloon dilation for acquired tricuspid valve atresia.

Acquired pulmonary valve atresia is a well-recognized but uncommon complication of surgical systemic-to-pulmonary artery shunts in patients with tetralogy of Fallot. Acquired atresia of the tricuspid valve, however, has not been reported previously. This complication developed in a 3-year-old girl, with pulmonary atresia and an intact ventricular septum, after a Blalock-Taussig shunt and right ventricular outflow tract reconstruction. Percutaneous transcatheter laser-assisted balloon dilation re-established antegrade flow across the tricuspid valve.

"Balloon valvulotomy" of congenital pulmonary valve stenosis with tricuspid valve insufficiency.

The rare congenital anomaly of pulmonary valve stenosis and massive tricuspid valve insufficiency with intact ventricular septum is a lethal condition without reported survival after attempted treatment. In a neonate suffering from this syndrome, the pulmonary valve stenosis was relieved by rupturing the fused valve with a balloon catheter introduced transvenously. The desperate condition of the patient quickly improved after this procedure, with subsequent disappearance of the tricuspid valve incompetence. Balloon rupturing of fused valves at angiography may represent a therapeutic alternative in cases in which surgical valvulotomy is associated with a high mortality.

Simulated tricuspid valve echoes in tricuspid atresia.

A case of tricuspid atresia with unusual echocardiographic findings is presented. The echocardiogram was successful in defining great artery interrelationships, ventricular looping, and cavity sizes. An echo pattern resembling the motion of a small tricuspid valve was observed; this was proven to be spurious at catheterization and necropsy. Caution should be exercised in diagnosing the presence of a tricuspid valve on the basis of atypical echoes from the tricuspid valve area.

Insertion of a pacing lead via the tricuspid valve does not affect cardiac function and tricuspid valve regurgitation in young dogs.

A preliminary experimental study in dogs was conducted to evaluate the feasibility of transvenous cardiac pacing in the fetus with complete heart block associated with hydrops. Four young mongrel dogs were anesthetized with intravenous administration of sodium pentobarbital and mechanically ventilated, and a pacing lead was inserted via the tricuspid valve. The right ventricular cardiac output, aortic pressure and central venous pressure were measured, and the tricuspid valve regurgitation was measured semi-quantitatively using echo-Doppler color flow imaging. The relationship between the location of the pacing lead and the tricuspid valve regurgitation and cardiac function was examined. The mean right ventricular cardiac output when the pacing lead was inserted into the superior vena cava (126 +/- 54 mL/min per kg) was not significantly different from that when it was inserted into the right ventricle (110 +/- 43 mL/min per kg). The aortic pressure was 66 +/- 7.7 mmHg and 67 +/- 6.6 mmHg, respectively, and the central venous pressure 5.9 +/- 1.7 mmHg and 5.7 +/- 1.6 mmHg, respectively, under the two conditions (not significantly different). The ratio of demonstrating significant tricuspid valve regurgitation was 4/13 into the superior vena cava and 5/13 into the right ventricle, respectively (not significantly different). The location of the pacing lead did not change the cardiac function or the amount of the tricuspid valve regurgitation in our experimental study. It was therefore concluded that the transvenous cardiac pacing technique has potential application in intrauterine transvenous cardiac pacing in the fetus with complete heart block.

Surgical strategy for severe tricuspid valve regurgitation complicated by advanced mitral valve disease: long-term outcome of tricuspid valve supra-annular implantation in eighty-eight cases.

OBJECTIVE: Although annuloplasty has been the most commonly performed surgical modality for severe tricuspid regurgitation, tricuspid valve supra-annular implantation has been performed in our hospital for more than a decade. The aim of this study was to assess the long-term outcome of tricuspid valve supra-annular implantation in a subgroup of patients with severe tricuspid regurgitation, those who also had advanced mitral valve disease. METHODS: Mitral valve replacement in conjunction with tricuspid valve supra-annular implantation was performed on 88 patients at our hospital between 1984 and 1998. The patients (mean age 57 +/- 11 years) were followed up for an average of 7.2 +/- 4.5 years after the operation (range 0-14 years); total follow-up was 643.1 patient-years. All patients except 2 (97.6%) were included in the follow-up. We evaluated the mortality, the cause of death, survival, the freedom from structural valve deterioration and reoperation, postoperative complications, and long-term echocardiographic findings. RESULTS: Overall survival at 14 years was 69% +/- 7.7%. Freedom from structural valve deterioration at 14 years was 100% and from reoperation, 88% +/- 9. 4%. There were no instances of pulmonary thromboembolism or of complications associated with fatal arrhythmias. Echocardiography showed little residual tricuspid regurgitation, no atrophic and stenotic change in the native tricuspid valve, and no thrombus formation between native valve and the implanted bioprosthesis. CONCLUSIONS: The procedure's simplicity, the good long-term durability of the bioprosthesis, and the absence of fatal arrhythmias and pulmonary thromboembolism indicate that tricuspid valve supra-annular implantation is a useful procedure for patients with severe tricuspid regurgitation complicated by advanced mitral valve disease.

Tricuspid valve prolapse.

Tricuspid valve prolapse is an infrequent echocardiographic finding that is most commonly associated with mitral valve prolapse. When compared with patients exhibiting isolated prolapse of the mitral valve, patients with tricuspid valve prolapse are somewhat older individuals with a slightly higher frequency of neurologic symptoms, fatigue, weakness, supraventricular arrhythmias (especially atrial fibrillation) and skeletal deformities. Tricuspid valve prolapse may serve as a marker of more-diffuse connective tissue abnormalities, and its identification also should prompt an echocardiographic search for evidence of prolapse and regurgitation of the other heart valves.

[Corrected transposition of the great arteries with associated tricuspid valve incompetence--report of a case of successful tricuspid valve replacement].

A 36-year-old woman with corrected transposition (C-TGA) of great arteries with associated systemic atrioventricular valve (A-V valve) regurgitation was presented. Cineangiography revealed that the right sided ventricle was morphologic left ventricle, and left sided ventricle was morphologic right ventricle. In addition, severe systemic A-V valvular regurgitation (Sellers IV) was demonstrated. Under the diagnosis of C-TGA with associated A-V valvular regurgitation, left sided atrioventricular valve replacement was performed using 29 mm SJM valve. Left sided atrioventricular valve was tricuspid valve (TV). A part of the anterior tricuspid leaflet and two pieces of papillary muscle was resected. Postoperative course was uneventful. The pathological findings indicated that valvular tissue had myxomatous degeneration.

Left ventricular myocardial performance in the fetus with severe tricuspid valve disease and tricuspid insufficiency.

We sought to determine whether left ventricular (LV) function is abnormal in a fetus with severe tricuspid valve disease (TVD), and whether it may contribute to the outcome. We measured the LV Tei index (including isovolumic relaxation [IRT], contraction, and ejection times) in 31 fetuses with TVD, compared the data with measurements from 32 normal fetuses, and correlated these measurements with pulmonary morphology and outcome. LV Tei index was significantly greater, ejection times shorter, and IRT longer in TVD compared with controls. The Tei index was highest in fetuses with either pulmonary insufficiency or atresia compared with those with forward flow. Finally, LV Tei index was significantly greater in fetuses with fetal (n = 5) or neonatal (n = 9) demise than in neonatal survivors (n = 7). Global LV performance as assessed by the Tei index is abnormal in TVD and likely contribute to the high mortality associated with TVD.

Use of a pericardial patch to bridge the conduction tissue during tricuspid valve replacement.

Tricuspid valve replacement carries a risk of causing complete heart block. To reduce this risk, a technique was developed to bridge the conduction system during prosthetic valve insertion in the tricuspid position. This technique, in which a pericardial patch is used to bridge the triangle of Koch, was performed successfully in 4 patients who underwent tricuspid valve replacement for Ebstein's anomaly of the tricuspid valve.

The connection between the papillary muscles and leaflets of the tricuspid valve.

The tricuspid valve is more differentiated during evolutionary development than the mitral valve. In birds it is a muscular structure joined directly to the papillary muscles, although the mitral valve of birds resembles that of mammals. There have been well-known studies describing the evolutionary line of connection of the tricuspid valve with the papillary muscles. The present study was performed on a group of 107 formalin-fixed adult human hearts. The valves and papillary muscles were classified according to a scheme for human hearts drawn up earlier. The types of connection between leaflets of the tricuspid valve and the papillary muscles were classified according to a scheme drawn up earlier for vertebrates. We observed 3 types of connection between leaflets of the tricuspid valve and the papillary muscles in the group studied. The muscular and membranous connections were not linked with any one type of tricuspid valve. Atypical forms of distribution of the tendinous chords of the right ventricle were observed. It was found that valves with a higher number of leaflets were (with the exception of type 0) provided with a smaller number of tendinous chords. Atavistic features and atypical forms of distribution of the tendinous chords are present in a small percentage of samples of the human right valvular apparatus.
