1/57. A case of diffuse endomyocardial fibrosis of the right ventricle with persistent pericardial effusion.

    A case of 42-year-old female with persistent pericardial effusion and recurrent congestive heart failure was presented. The clinical course, laboratory and cardiac evaluations confirmed the existence of tricuspid incompetence and restrictive condition of the right ventricle. At autopsy, the right atrium and ventricle showed moderate hypertrophy, the left ventricle being almost completely spared macroscopically. Diffuse fibrous thickening of the right atrial and ventricular endomyocardium with mural thrombi, and mild lymphocytic infiltation were noted microscopically. These findings are compatible with endomyocardial fibrosis described by Davies. The etiology and pathogenesis of the disease were discussed.

2/57. Unusual eustachian valve function.

    The eustachian valve directs oxygen-rich blood from the inferior vena cava toward the foramen ovale and away from the tricuspid valve during fetal development. Ordinarily, it does not prevent reflux of right atrial blood back into the inferior vena cava because it does not function as a true valve. Here we describe an unusual adult patient with severe tricuspid valve regurgitation in whom the eustachian valve did function as a true, albeit regurgitant, valve.

3/57. Transient neonatal cyanosis: unusual presentation of right-sided cardiac masses.

    We report a case of a neonate with multiple cardiac masses, cyanosis, and a heart murmur. Arterial desaturation was the result of right-to-left shunting at the foramen ovale level caused by tricuspid regurgitation. Three right-sided cardiac masses were detected by echocardiography. By 2 weeks of age the patient had complete resolution of his cyanosis and improved tricuspid regurgitation following the normal decrease in pulmonary vascular resistance. At 2 years of age, he has no cardiovascular symptoms and the masses are calcified and have no hemodynamic consequences.

4/57. Iatrogenic left ventricular-right atrial fistula following mitral valve replacement and tricuspid annuloplasty: diagnosis by transthoracic and transesophageal echocardiography.

    Acquired left ventricle-to-right atrium communications are a known complication of valvular heart surgery. Previous reports have described the clinical features and diagnosis using cardiac catheterization. We report two cases of acquired left ventricle-to-right atrium fistula following mitral valve replacement. Particular emphasis is placed on the diagnosis using transthoracic and transesophageal echocardiography, obviating the need for cardiac catheterization before repair.

5/57. Cleft on tricuspid anterior leaflet.

    We report a case of isolated congenital tricuspid regurgitation caused by a cleft in the anterior tricuspid leaflet associated with a patent foramen ovale. Preoperative echocardiography revealed severe tricuspid regurgitation resulting from anterior tricuspid leaflet prolapse. The patient underwent successful tricuspid valve repair with simple cleft suture and annuloplasty and direct closure of the patent foramen ovale.

6/57. Atrial blood cyst in an adult with regurgitation of mitral and tricuspid valves.

    blood cysts of the heart are extremely rare in adults and usually involve valves or the left ventricle. Although two cases of blood cysts in the right atrium in adults have been reported, a cyst combined with a disorder of the valves has never been reported. We report a 52-year-old woman with a blood cyst that generated from the right atrial septum. Furthermore, the patient had regurgitation of both the mitral and tricuspid valves and then underwent surgical excision of the blood cyst, mitral valve plasty and tricuspid valve annuloplasty. We believe that it is possible to diagnose blood cysts with echocardiography, CT and magnetic resonance imaging. echocardiography showed the cyst as a circle without a complete inner free-echo. CT and magnetic resonance imaging showed a mass with a non-enhanced inner structure. Furthermore, the latter showed a cyst that was enhanced by T1- but not T2-weighted images, indicating that the content of the cyst was a persistent substance such as blood. Concerning the generation of blood cysts, we hypothesize that heteroplastic growth arising from primitive pericardial mesothelium causes disorders of valves and blood cysts.

7/57. Double switch operation for superior-inferior ventricles.

    Superior-inferior ventricles are a rare cardiac malformation characterized by the two ventricles lying one above the other instead of side by side. Consequently, the interventricular septum that separates such ventricles is horizontal, and anomalies of the atrioventricular valves and the ventriculoarterial relations are almost always present. This complex anomaly is difficult to manage with an operation, so few cases have been reported. We describe a successful experience in which we performed a double switch operation, consisting of the Senning and Jatene procedures, for this rare malformation accompanied by double-outlet right ventricle [S,L,L]. This is the first report we have been able to locate of a double switch operation for superior-inferior ventricles.

8/57. Acquired right heart outflow tract anomaly without systemic hypertension in recipient twins in twin-twin transfusion syndrome.

    Significant hemodynamic changes are commonly observed in both fetuses in twin-twin transfusion syndrome. In the recipient twin there is cardiac dysfunction with hypertrophy of both ventricles and overall enlargement of the heart. We describe five cases of recipient twins in twin-twin transfusion syndrome with right ventricle hypertrophy, pulmonary stenosis and tricuspid regurgitation acquired in utero. These symptoms developed with no signs of systemic hypertension. Three of the five recipient twins survived and were developing normally at 3-30 months of age. Postnatal outcome is likely to have improved as a result of prenatal diagnosis of right ventricle outflow tract obstruction and timed delivery. These acquired anomalies of the right heart might be related to the particular hemodynamic conditions of the recipient twin. A global heart dilatation is logically expected, but this hypertrophy without dilatation is probably related to the shared plasma of fetuses with opposite hemodynamic conditions. This is what we consider as the hemodynamic-hormonal paradox. These acquired anomalies, though severe, are accessible to neonatal treatment if treated early.

9/57. Persistent atrial standstill due to atrial inexcitability. An electrophysiological and histological study.

    Electrophysiological and histopathological examinations were carried out in 2 patients with persistent atrial standstill. Intracardiac studies revealed that atrial standstill was due to atrial inexcitability. It was demonstrated in both patients that prolongation of the H-V interval and the duration of H deflection was associated with complete right bundle branch block and that the escape rhythm was an A-V junctional origin. Histologically, marked fibrosis of the right atrium and fibrous strands in the right ventricle were demonstrated in a 69-year-old man with idiopathic cardiomyopathy. In another female patient with peripartum heart disease aged 40 years, there was moderate degeneration of the myocardium in the right ventricle. The results of electron microscopic observations are also presented. The importance of the examination of His bundle electrography in persistent atrial standstill and the diagnostic criteria and treatment of this lesion are discussed.

10/57. Staged fontan procedure for mitral atresia associated with severe tricuspid regurgitation, pulmonary hypertension, and pulmonary artery distortion.

    Optimal initial palliation and a subsequent staged approach is mandatory for high-risk Fontan candidates. We describe the case of mitral atresia with severe tricuspid regurgitation and pulmonary hypertension successfully managed by repeated palliation from the neonatal period and 2-stage Fontan surgery. A 1-month-old boy diagnosed with mitral atresia and double-outlet right ventricle underwent pulmonary artery banding at 1 month of age, followed by repeated pulmonary artery banding accompanied by tricuspid annuloplasty and atrial septal defect enlargement at 6 months. Because of the presence of pulmonary artery distortion, right ventricular dysfunction, and borderline pulmonary vascular resistance, a hemi-fontan procedure was conducted with extended pulmonary artery plasty when the boy was 3 years and 8 months old. cardiac catheterization done 3 months after showed improvement in risk factors, and the final Fontan operation (total cavopulmonary connection) was successfully done in conjunction with repeated tricuspid annuloplasty when the boy was 4 years and 5 months old. The patient remains in excellent clinical condition at the last follow-up 5 years after the final fontan procedure with sinus rhythm and good ventricular function.
