We report a successful repair of severe traumatic tricuspid regurgitation by PTFE chordal replacement and ring annuloplasty. A 64-year-old man with multiple trauma was referred to our department because of cardiomegaly on chest roentgenogram. Echocardiography showed moderate amount of pericardial effusion and severe tricuspid regurgitation with rupture of anterior papillary muscle. But he experienced progressive dyspnea, and chest roentgenogram showed pro ressive cardiomegaly. He underwent operation 4 months after trauma. The nterior papillary muscle was reinserted, and the valve was repaired by PTFE chordal replacements and ring annuloplasty. Postoperatively, the patient's functional status was improved, and there was trivial tricuspid regurgitation on echocardiographic examination.

A 52-year-old man was taken to the emergency room following a motor vehicle accident. An echocardiogram showed moderate to severe tricuspid regurgitation due to rupture of the anterior chordae. An operation to repair the tarumatic tricuspid regurgitation was recommended; however, the patient refused because he was asymptomatic. Two years later, he developed mild generalized edema and dyspnea. The echocardiogram revealed progressive severe tricuspid regurgitation and annular dilatation. We treated the tricuspid regurgitation successfully using artificial chordae and ring annuloplasty.

Purpose : The prognosis of patients with corrected transposition of the great arteries(C-TGA) is variably affected by associated intracardiac defects, systemic right ventricular function, tricuspid valve competence, and conduction disturbances. This study aims to evaluate the importance of those factors at mid-term follow-up. Methods : Medical records of 94 patients(males 58, females 36; mean age at last follow-up, $12{\pm}9$ years; mean follow-up duration, $9{\pm}6.4$ years) diagnosed between January 1980 and May 2002 at Seoul National University Children's Hospital were studied retrospectively. Results : Among 94 patients, operations were performed in 72 patients(classic operations in 55; double switch operations in 17). Among prognostic factors including associated intracardiac anomalies(at least moderately severe tricuspid insufficiency(TI), ventricular septal defect, pulmonary stenosis and pulmonary atresia), intracardiac operation and complete atrioventricular block, TI was the only significant factor for death(P=0.001), and in turn, Ebstein anomaly and high grade atrioventricular block predicted TI. 20-year survival without TI was 77%, but only 35% with TI(P=0.0002); excluding perioperative death, the 20-year survival rates with and without TI were 48% and 87% respectively(P=0.008). There was no statistical difference in 20-year survival rate or association with TI between classic and double switch operation. Conclusion : TI was the major prognostic factor for C-TGA and was associated with Ebstein anomaly and high grade atrioventricular block at mid-term follow-up. Long-term follow-up is required to evaluate other factors, including double switch operations and associated intracardiac defects more exactly.

Ebstein's anomaly is a complex congenital defect of the tricuspid valve and right ventricle. Various surgical methods to repair the regurgitant tricuspid valve have been reported, and most of them depend on monocuspidalization with using the anterior leaflet. We report here on our first experience with Ebstein's anomaly in a 31-year-old female patient who underwent cone reconstruction of the tricuspid valve with using three leaflets.

There are various surgical techniques in repairing Ebstein anomaly, but residual tricuspid regurgitation and compromized right heart function may ensue in some cases. We report our clinical experience of Ebstein anomaly and atrial flutter in a 19-year-old male patient who underwent simple modified tricuspid annuloplasty, hi-directional cavopulmonary shunt and cryoablation of cavotricuspid isthmus.

A 51-year-old male was admitted three month previously with a cardiac stab injury and he underwent direct cardiac repair He had no problem after this event. He complained of dyspnea that stalled 2 months after the original injury. Echocardiography showed severe tricuspid regurgitation and so, chordac replacement and ring annuloplasty was performed. Herein we report on a case of tricuspid valve repair for treating tricuspid insufficiency following a cardiac stab injury.

We report a case of an 8 years and 11 month-old male patient who had developed severe tricuspid insufficiency(TI) after correction of anomalous origin of the left coronary artery from the pulmonary artery(ALCAPA). Transthoracic echocardiogram and coronary angiography confirmed ALCAPA, ischemic mitral regurgitation and trivial TI. He underwent direct reimplantation of the left coronary artery to the aortic root by using additional cannulation at the main pulmonary artery for arterial inflow and cardioplegia delivery to the left coronary artery. After the correction of ALCAPA, transesophageal echocardiogram(TEE) revealed good antegrade flow at the aortic implantation site of the left coronary artery and severe TI(Gr III-IV/IV). Cardiopulmonary bypass was reestablished and tricuspid valve was repaired with Kay-type annuloplasty, artificial chordae formation and chordal shortening plasty. The postrepair TEE revealed trivial to mild TI.

A 1-year-old castrated male Maltese dog(weighing 2.4 kg) was presented with primary complaints of occasional coughing, dyspnea and exercise intolerance. Based on diagnostic findings including paradoxical split S2, diastolic regurgitant murmur, marked dilation of pulmonary artery, right ventricular eccentric hypertrophy with thickening of ventricular septum, severe tricuspid and pulmonic regurgitation(5.4 m/sec and 3.4 m/sec, respectively) and the absence of any congenital intracardiac shunting, obstructive pulmonary diseases and systemic diseases associated with right ventricular pressure overload or pulmonary hyperperfusion, the case was tentatively diagnosed as primary pulmonary hypertension. The dog was treated with furosemide, aspirin and oxygen supplementation. This case report described a rare case of primary pulmonary hypertension in a Maltese dog.

A 12-year-old intact female mixed dog (weighing 6.2 kg) was referred with primary complaints of severe abdominal distension, persistent coughing and exercise intolerance. Diagnostic studies found ascites, jugular distension, loud left and right apical systolic (grade 4/6) murmur, generalized cardiomegaly with caudal vena cava distension and left atrial dilation. Echocardiographic findings were consistent with degenerative mitral and tricuspid valve endocardiosis and bi-ventricular congestive heart failure. There was also a left to right shunting patent foramen ovale. The LV systolic function is depressed relative to the degree of volume overload. Based on diagnostic findings, this case was diagnosed as PFO complicated with mitral and tricuspid valve endocardiosis with ISACHC IIIa heart failure. The dog was treated with furosemide (2 mg/kg, q12hr, PO), sildenafil (1 mg/kg, q8hr, PO), pimobendan (0.3 mg/kg, q12hr, PO), enalapril (0.5 mg/kg, q12hr, PO) and spironolactone (1 mg/kg, q12hr). The clinical signs were gradually improved after medical therapy.

This is a report of a successful management of a patient with infective endocarditis involving native aortic valve, mitral valve, tricuspid valve, and Interventric lar septum. A 16 year-old patient who underwent VSD patch closure, and aortic valvuloplasty at the age of 1 1 years showed Intractable congestive heart failure during antibiotics treatment for infective endocarditis. Operative findings revealed that there were large defect along the previous patch, aortic regurgitation with multiple perforations and vegetations, mitral regurgitation with vegetation, aortic paraannular abscess, interventricular myocardial abscess, and tricuspid regurgitation with perforations and vegetations. We reconstructed the interventricular defect with Dacron patch extending to the aortic valve annulus after radical debridement of all infected or devitalized tissues, and could implant aortic valve by anchoring to the reconstructed Dacron patch. Mitral valve was replaced and tricuspid valve was repaired with patient's own pericardium. The patient was discharged after antibiotics treatment for 6 weeks and in good condition without any sequelae for 12 months.
