A 4-years-old, intact male Golden retriever dog was presented with abdominal distension and dyspnea. Physical examination revealed arrhythmia and cardiac murmur. Generalized cardiomegaly, pleural effusion and ascites were shown on thoracic and abdominal radiographs. Two-dimensional echocardiography revealed abnormal mitral and tricuspid valve motion, mitral and tricuspid regurgitation, left ventricular eccentric hypertrophy and left atrial dilation. Color-flow Doppler imaging revealed turbulent flow extending into the left ventricle during diastole from the mitral valve orifice, and into the left atrium during systole. Spectral Doppler recordings revealed highly increased early diastolic mitral valve inflow and prolonged pressure half-time of mitral inflow. Based on the echocardiographic examination, the diagnosis was made as the mitral valve dysplasia concurrent with mitral valve stenosis and tricuspid valve dysplasia.

The incidence and importance of tricuspid valve regurgitation after a blunt chest injury has risen with the increase in the number of automobile accidents and steering wheel traumas. This kind of injury has been reported more frequently in the last decade because of the better diagnostic procedures and understanding of the pathology. However, tricuspid valve regurgitation following a blunt chest injury can still be easily missed because most patients do not show symptoms at the time of the trauma. A 55-year-old male patient presented himself at our facility after suffering a chest injury from an automobile accident. His transthoracic echocardiography (TTE) revealed severe tricuspid valve regurgitation due to the prolapse of his anterior valve leaflet. We report a case of asymptomatic tricuspid regurgitation that developed after a blunt chest injury.

Tricuspid annuloplasty with the flexible Duran ring may result in a physiologic repair while maintaining the dynamic morphology of the tricuspid annulus. A method for a durable three-dimensional tricuspid annular reconstruction, which retains the plasticity and orifice area of the tricuspid annulus, is described.

An eight-year-old boy was referred to our hospital with cough and high fever. His past medical history included a small sized ventricular septal defect (VSD) at birth. Transthoracic echocardiography disclosed a 10 x 6 mm vegetation on tricuspid valve, a small VSD and the moderate tricuspid valve insufficiency were found. Blood cultures grew methicillin-resistant staphylococcus aureus. Despite proper antibiotic therapy, fever was not controlled and his course was complicated by pulmonary infarction. The patient simultaneously underwent pulmonary resection and open heart surgery. Through the median sternotomy we performed open thrombectomy and lobectomy (right lower lobe) at first, and then vegetectomy, tricuspid valve repair, and direct closure of VSD were done under cardiopulmonary bypass.

A case of congenital tricuspid stenosis in 24 year old male patient is presented. The lesion was successfully corrected with prosthetic valve replacement and closure of atrial and ventricular septal defects. Especially, this is the first reported case of successful large prosthetic valve replacement to a small annulus in tricuspid valve.

Background: The late progression of tricuspid regurgitation (TR) after mitral valve surgery is well known. However, few reports have described the progression of TR after aortic valve surgery. We investigated the incidence of and risk factors for the development of significant TR after isolated aortic valve replacement (AVR). Methods: This study analyzed patients with less than moderate TR who underwent isolated AVR at Seoul National University Hospital from January 1990 to December 2018. Significant TR was defined as moderate or higher. Echocardiographic follow-up was performed in all patients. The Fine-Gray model was used to identify clinical risk factors for the development of significant TR. Results: In total, 583 patients (61.7±14.2 years old) were included. Operative mortality occurred in 9 patients (1.5%), and the overall survival rates at 10, 20, and 25 years were 91.1%, 83.2%, and 78.9%, respectively. Sixteen patients (2.7%) developed significant TR during the follow-up period (13 moderate; 3 severe). The cumulative incidence of significant TR at 10, 20, and 25 years was 0.77%, 3.83%, and 6.42%, respectively. No patients underwent reoperation or reintervention of the tricuspid valve. Hemodialysis or peritoneal dialysis for chronic kidney disease (hazard ratio [HR], 5.188; 95% confidence interval [CI], 1.154-23.322) and preoperative mild TR (HR, 5.919; 95% CI, 2.059-17.017) were associated with the development of significant TR in the multivariable analysis. Conclusion: TR progression after isolated AVR in patients with less than moderate TR is rare. Preoperative mild TR and hemodialysis or peritoneal dialysis for chronic kidney disease were significant risk factors for the development of TR.

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.

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 total and consecutive 46 patients have undergone cardiac valvular surgery including 8 open mitral commissurotomy and 38 mitral, aortic, mitral-aortic, mitral-tricuspid, tricuspid valve replacements using 46 artificial valves in a period between September 1976 and July 1981. They were 19 males and 27 females with the age ranging from 16 to 50 (mean 32.6) years. Out of 46 valves replaced, 6 were prosthetic valves and 40 were tissue valves, and 33 were replaced in mitral, 9 in aortic and 3 In tricuspid position. Isolated replacements were 33 mitral valves, 6 aortic valves and 1 tricuspid valve; double valve replacements were 6 mitral-aortic valves and 2 mitral-tricuspid valves. . Early mortality within 30 days after operation was noted in 4 cases; 3 after MVR and 1 after open mitral commissurotomy. Causes of death were thrombus obstruction of Beall-Surgitool, Cerebral air embolism, acute renal shut down due to low output syndrome, and left upper pUlmonary vein rupture after open mitral commissurotomy (early mortality 8.7%). 3 late deaths were noted during the follow-up period from 2 to 59 months; 1 due to cerebral hemorrhage from warfarin overdose 3 months, 1 due to miliary tuberculosis 9 months, and another 1 due to cardiac failure after open mitral commissurotomy 42 months postoperatively. Total survival rate 59 months after valvular surgery was 84.8%; there were no early and late death in the group of AVR, TVR and double valve replacements. Preoperative NYHA Class III & IV were 35 cases (76%) out of total 46 cases, and 38 cases (94.8%) out of 39 survival cases were included In NYHA Class I & II during the follow-up period.

Ebstein`s anomaly is characterized by a downward displacement of a malformed tricuspid valve, The ideal surgical management of Ebstein`s anomaly is not yet established. Recently we experience one case of Ebstein`s anomaly, which was treated sussessfully by partial artificial annulus formation, and tricuspid valve replacement with St. Jude Medical valve. We have achieved excellent results with mechanical valve replacement and partial artificial annulus formation using wessex pericardial patch. On follow up for 4 years, the patient is well and in functional class I.
