Tricuspid regurgitation due to rupture of a chorda is a rare disease in newborns. Recently, we experienced one day old male with tricuspid regurgitation due to rupture of a chorda of anterior papillary muscle, and who had suffered from severe hypoxemia, acidosis, cyanosis, and bradycardia. Preoperative diagnosis was pulmonary atresia with intact ventricular s ptum, massive tricuspid regurgitation, and patent ductus arteriosus by echocardiogram, which demonstrated no flow through the pulmonic valve. At operation, the pulmonic valve was intact and a chorda of anterior papillary muscle was ruptured. Tricuspid regurgitation was corrected successfully with reconstruction of the chords. Postoperative course was complicated by pneumonia and sepsis, but the infant recovered and discharged at postoperative 20 days.

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.

Two stents were placed across the right subclavian vein due to stenosis of the right subclavian vein in a 40-year-old patient with chronic renal failure on hemodialysis. During the follow up period, one of stents migrated into the right ventricle inducing tricuspid valve insufficiency. Percutaneous stent removal had failed and the stent was removed by open heart surgery with Tricuspid valve repair with a good result, and then we report the case.

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 assessed the intermediate-term result of tricuspid annuloplasty (TAP) for tricuspid valve regurgitation (TR) associated with congenital heart disease in adults. Risk factors for residual TR were also analysed. Material and Method: From August 1989 to June 2001, seventy three adult patients, 51 females and 22 males, underwent TAP for TR associated with various congenital heart disease. Their age ranged from 46 years to 73 years (mean:43). Associated heart anomalies were atrial septal defect (55), ventricular septal defect (6), partial anomalous pulmonary venous return (4) and others (8). Preoperative and post-operative TR velocities were 3.25 m/sec and 2.56 m/sec respectively, and the types of TAP were De Vega in 43, Kay in 18 and Ring annuloplasty in 12. Postoperative follow-up duration was 2,347 patient-month (mean: 32.6 months), and 134 two-dimensional echocardiographic examinations were done during this period. Residual TR greater than III/IV was considered as TAP failure. Result: TAP failure was observed in 7 patients (9.6%), and one patient among them underwent tricuspid valve replacement. Risk factors for TAP failure were diagnosis other than atrial septal defect (p=0.001), preoperative (p=0.038) and postoperative (p=0.028) high TR velocity. There was no statistical significance in terms of TAP methods. Conclusion: Careful evaluation of valve morphology and aggressive surgical intervention are mandatory for the repair of TR with preoperative or residual RV pressure overload.

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.

Sometimes temporary tricuspid valve detachment is applied for closure of ventricular septal defect to facilitate good exposure and avoiding ventriculotomy, but most surgeons hesitate to do it in the fear of tricuspid incompetence. Moreover in recent textbooks the technique of temporary tricuspid detachment is only described for exceptional situations and is not further analysed or commented on. Material and Method: Retrospective study was carried out in all 11 patients operated between 1985 to 1994, with preoperative data and postoperative course and recent echocardiographic and electrocardiographic data. Result: On the basis of the area of the color flow jet, tricuspid valvular regurgitation was graded as none in 9 and trivial in 2, and significant electrocardiographic heart block did not developed in any patients. Conclusion: Takedown and attachment of the tricuspid valve is a safe and effective technique that improves exposure for ventricular septal defect, and does not adversely effect tricuspid valve competence and electrocardiography.

Background: Functional tricuspid regurgitation (TR) greater than or equal to a mild grade requires tricuspid valvuloplasty, and tricuspid valvuloplasty with ring annuloplasty has shown good outcomes. We report here on our early experience with the Edwards $MC^3$ annuloplasty system (Edwards LifeSciences, Irvine, CA). Material and Method: From November 2004 to July 2006, 72 patients with tricuspid annular dilatation and TR underwent tricuspid valvuloplasty with using the Edwards $MC^3$ annuloplasty ring. Sixty-eight patients were operated on via median sternotomy and four patients were operated on using robotic assisted minimal invasive thoracotomy. The patient population included 21 males and 51 females and their mean age was $53.9{\pm}12.3$. The mean grade of TR, as assessed by the preoperative echocardiography, was $2.2{\pm}1.0$. The mean NYHA functional class was $3.1{\pm}0.8$. The mean left ventricular ejection fraction was $57.0{\pm}9.9$%. Result: The TR and NYHA functional class, as assessed by postoperative echocardiography, was significantly reduced (mean=$0.4{\pm}0.6$ and $2.0{\pm}0.7$, respectively p<0.001). There was one case of hospital mortality. One patient required permanent pacemaker insertion for third degree atrioventricular block. Conclusion: Our study shows that the Edwards $MC^3$ remodeling ring is easy to implant and it effectively corrects functional TR with excellent clinical and echocardiographic outcomes. Further follow-up and a larger clinical series are required to establish the long-term stability of this repair technique.

Systemic arteriovenous(AV) fistulas are a rare but well-recognized cause of hyperkinetic circulation that, if undetected, may lead to congestive heart failure. We experienced a very rare case of acquired arteriovenous fistula. A 61-year-old female patient presented with congestive heart failure symptoms after percutaneous pinning for right sternoclavicular joint dislocation. We surgically obliterated the fistula between aorta and innominate vein and performed tricuspid annuloplasty for severe tricupid insufficiency simultaneously. She was discharged with complete relief of her symptoms and has been well during 2 years and 6 months follow up.

Background: Sixty five cases with congenitally corrected transposition of the great arteries (CCTGA) indicated for biventricular repair were operated on between 1984 and september 1998. Comparison between the results of the conventional(classic) connection(LV-PA) and the anatomic repair was done. Material and Method: Retrospective review was carried out based on the medical records of the patients. Operative procedures, complications and the long-term results accoding to the combining anomalies were analysed. Result: Mean age was 5.5$\pm$4.8 years(range, 2 months to 18years). Thirty nine were male and 26 were female. Situs solitus {S,L,L} was in 53 and situs inversus{I,D,D} in 12. There was no left ventricular outflow tract obstruction(LVOTO) in 13(20%) cases. The LVOTO was resulted from pulmonary stenosis(PS) in 26(40%)patients and from pulmonary atresia(PA) in 26(40%) patients. Twenty-five(38.5%) patients had tricuspid valve regurgitation(TR) greater than the mild degree that was present preoperatively. Twenty two patients previously underwent 24 systemic- pulmonary shunts previously. In the 13 patients without LVOTO, 7 simple closure of VSD or ASD, 3 tricuspid valve replacements(TVR), and 3 anatomic corrections(3 double switch operations: 1 Senning+ Rastelli, 1 Senning+REV-type, and 1 Senning+Arterial switch opera tion) were performed. As to the 26 patients with CCTGA+VSD or ASD+LVOTO(PS), 24 classic repairs and 2 double switch operations(1 Senning+Rastelli, 1 Mustard+REV-type) were done. In the 26 cases with CCTGA+VSD+LVOTO(PA), 19 classic repairs(18 Rastelli, 1 REV-type), and 7 double switch operations(7 Senning+Rastelli) were done. The degree of tricuspid regurgitation increased during the follow-up periods from 1.3$\pm$1.4 to 2.2$\pm$1.0 in the classic repair group(p<0.05), but not in the double switch group. Two patients had complete AV block preoperatively, and additional 7(10.8%) had newly developed complete AV block after the operation. Other complications were recurrent LVOTO(10), thromboembolism(4), persistent chest tube drainage over 2 weeks(4), chylothorax(3), bleeding(3), acute renal failure(2), and mediastinitis(2). Mean follow-up was 54$\pm$49 months(0-177 months). Thirteen patients died after the operation(operative mortality rate: 20.0%(13/65)), and there were 3 additional deaths during the follow up period(overall mortality: 24.6%(16/65)). The operative mortality in patients underwent anatomic repair was 33.3%(4/12). The actuarial survival rates at 1, 5, and 10 years were 75.0$\pm$5.6%, 75.0$\pm$5.6%, and 69.2$\pm$7.6%. Common causes of death were low cardiac output syndrome(8) and heart failure from TR(5). Conclusion: Although our study could not demonstrate the superiority of each classic or anatomic repair, we found that the anatomic repair has a merit of preventing the deterioration of tricuspid valve regurgitations. Meticulous selection of the patients and longer follow-up terms are mandatory to establish the selective advantages of both strategies.
