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.

Severe tricuspid regurgitation resulting from a flail leaflet is a rare cause of neonatal cyanosis. We report a neonate with profound cyanosis and severe tricuspid regurgitation caused by a rupture of the papillary muscle supporting the anterior leaflet, without other structural heart defects. Ductal patency could not be established. The repair of the tricuspid valve was performed after initial stabilization by using extracorporeal membrane oxygenation.

Background: A ring implantation in the tricuspid annulus requires many interrupted mattress sutures for correction of tricuspid regurgitation (TR). In this study, tricuspid ring annuloplasty was performed by 2-0 polypropylene continuous suture instead of multiple interrupted 2-0 polyester mattress sutures, and the efficacy of the method was evaluated. Materials and Methods: This study included 20 patients who underwent tricuspid ring annuloplasty by continuous suture between May 2009 and July 2010. Four of the patients had an isolated TR, and the rest had a left-sided cardiac lesion. The concomitant tricuspid annuloplasty was performed after the left-sided heart surgery was completed and a Duran flexible ring prosthesis was used. Results: There was no perioperative mortality or conduction problem. More than a moderate degree of TR was improved to less than a mild degree after the procedure. After the ring annuloplasty, the right atrial volume decreased from $123.7{\pm}69.2mL$ to $74.5{\pm}37.4mL$, and the mean right atrial pressure was lowered from $18.7{\pm}12.2mmHg$ to $8.9{\pm}5.5mmHg$. Conclusion: The continuous "over and over" suture may be a useful procedure for fixing the ring to the annulus and making an intentional annular placation in performing tricuspid ring annuloplasty.

Ninety-one adult patients underwent three different methods of annuloplasty and compared them by the amount of tricuspid regurgitation. Group I [n=17 is Kay method, Group II [n=46 is modified Kay method and Group III [n=28 is De Vega and modified De Vega method. Preoperative and postopeative size of the liver and its function, the cardiothoracic ratio, EKG and echocardiogram were analyzed. The follow up was done for all the patients [mean 20.0$\pm$ 8.5 months . The postoperative size of the liver, the postoperative cardiothoracic ratio and the postoperative systolic pressure of the right ventricle decreased significantly compared to preoperative size, ratio and pressure [p=0.0001, p=0.0001, p=0.0001 . But there were no differences between the groups. The results of annuloplasty revealed that tricuspid regurgitation improved postoperatively [p=0.0001 even though there was no statistically significant differences in relation to the methods of annuloplasty. The right ventricular systolic pressure and the amount of regurgitation decreased significantly during the postoperative period by performing 3 different methods of annuloplasty, although we could not find the differences between the three different methods.

Complete and optimal visualization of the mitral apparatus is a prerequisite for accurate repair or replacement of the mitral valve. A vertical left atriotomy just posterior to the interatrial groove is the most commonly used approach. However,exposure can be difficult under certain circumstances,such as small left atrium or reoperation. Other approaches have been advocated to deal with this difficult situations. We used an extended transseptal approach in 10 patients and good clinical results and excellent educational effects were obtained. The extended transseptal approach combines two semicircular atrial incisions circumscribing the tricuspid and mitral annuli anteriorly and superiorly,allowing exposure of the mitral valve by deflecting the ventricular side using stay sutures. The right atrium is opened anteriorly along the atrioventricular sulcus. The atrial septum is incised vertically through the fossa ovalis. Right atrial and septal incisions are joined at the superior end of the interatrial septum and extended across the dome of the left atrium to the left atrial appendage. The mitral valve was replaced in all 10 patients. Four of 10 patients had other simultaneous valve procedure: one had aortic valve replacement: 2 underwent tricuspid annuloplasty: 1 had aortic valve replacement and tricuspid annuloplasty. There was no hospital death and complication. Among the 5 patients who had atrial fibrillation preoperatively,4 had atrial fibrillation postoperatively,1 converted to sinus rhythm. The five patients who were in normal sinus rhythm preoperatively remained in sinus rhythm after replacement. A review of our results with this approach confirms the efficacy and safty of this method. So we recommanded this approach for routine mitral valve procedure,especially difficult situations,such as a small left atrium or the redo operation.

From Jan 1982 through Dec.1991, thirty-three DeVega`s tricuspid annuloplasties were performed in association with mitral and combined mitral and aortic valve disease. Preoperatively,all of the patients were in NYHA functional class III or IV.There were one early death and 4 patients died during follow up period of 18 to 138 months [ mean follow up : 67.3 months ]. Nine patients required reoperation because of biological mitral valve failure at 4.7 to 11 years after tricuspid annuloplasty[TAP]. Among these patients,2 cases needed for reoperation of TAP due to loosening of suture material. Twenty four [86%] of the survivors were in NYHA functional class I or II after TAP.The actuarial survival rate for the TAP was 74% at 138 months. Rt atrial pressure of 9 reoperation cases were significantly decreased [P<0.05] compared with initial Rt.atrial pressure [ Mean period; 93.6 months].Doppler echocardiographic studies for tricuspid regurgitation were performed in 15 cases after TAP [Mean period: 42.3 months].These results showed significantly reduced [P<0.01] tricuspid annulus diameter and tricuspid regurgitation distance [ P<0.05 ].Our surgical experience that the DeVega`s TAP is a simple,safe,effective procedure and resulted in good hemodynamic improvement with moderate to severe functional tricuspid regurgitation.

The CarboMedics mechanical valve has been reported to show acceptable valve-related complication rates. The aim of this study is to evaluate our clinical experience with the CarboMedics valve. Material and Method: Between August 1988 and September 1999, we implanted 1,144 CarboMedics valves in 850 patients (aortic 179; mitral 385; double-valve 234; tricuspid 52). The mean age was 44.5 $\pm$ 12.5 years. Follow-up was completed in 95.2% and median follow-up period was 7.9 years (6753 patient-years). Result: The overall hospital mortality rate was 3.4% and the mortality rate for each group was 1.7% for aortic group, 2.6% for mitral group, 4.7% for double-valve group, and 9.6% for tricuspid group, Tricuspid group showed significantly higher mortality rate than aortic and mitral group (p〈0.05). The actuarial survival at 10 years was 87.1 $\pm$ 2.6%, 88.9 $\pm$ 1.7%, 82.4 $\pm$ 2.9%, and 77.5 $\pm$ 7.0% for aortic, mitral, double, and tricuspid valve group, respectively. Age and tricuspid valve replacement were significant risk factors for long-term survival in multivariate analysis (p 〈 0.05). Freedom from valve thrombosis at 10 years was 99.4 $\pm$ 0.6%, 98.2 $\pm$ 0.8%, 99.2 $\pm$ 0.8%, and 87.6 $\pm$ 0.5% for aortic, mitral, double and tricuspid valve group. Tricuspid valve group showed significantly higher rate of valve thrombosis (p 〈 0.05). Conclusion: Long-term results of our experience demonstrated that CarboMedics valve showed acceptable incidence of valve-related complications. However, tricuspid valve replacement showed higher rate of early mortality and valve thrombosis than other valve replacement groups.

Background: Edwards Intuity is recognized as a relatively contraindicated bioprosthesis for bicuspid aortic valve disease. This study compared the early echocardiographic and clinical outcomes of rapid-deployment aortic valve replacement for bicuspid versus tricuspid aortic valves. Methods: Of 278 patients who underwent rapid-deployment aortic valve replacement using Intuity at Seoul National University Hospital, 252 patients were enrolled after excluding those with pure aortic regurgitation, prosthetic valve failure, endocarditis, and quadricuspid valves. The bicuspid and tricuspid groups included 147 and 105 patients, respectively. Early outcomes and the incidence of paravalvular leak were compared between the groups. A subgroup analysis compared the outcomes for type 0 versus type 1 or 2 bicuspid valves. Results: The bicuspid group had more male and younger patients. Comorbidities, including diabetes mellitus, hypertension, chronic kidney disease, and coronary artery disease, were less prevalent in the bicuspid group. Early echocardiographic evaluations demonstrated that the incidence of ≥mild paravalvular leak did not differ significantly between the groups (5.5% vs. 1.0% in the bicuspid vs. tricuspid groups, p=0.09), and the early clinical outcomes were also comparable between the groups. In the subgroup analysis between type 0 and type 1 or 2 bicuspid valves, the incidence of mild or greater paravalvular leak (2.4% vs. 6.7% in type 0 vs. type 1 or 2, p=0.34) and clinical outcomes were comparable. Conclusion: Rapid-deployment aortic valve replacement for bicuspid aortic valves demonstrated comparable early echocardiographic and clinical outcomes to those for tricuspid aortic valves, and the outcomes were also satisfactory for type 0 bicuspid aortic valves.

Amyloid deposits in the heart are not exceptional in systemic amyloidosis. The clinical manifestations of cardiac amyloidosis may include restrictive cardiomyopathy, characterized by progressive diastolic and eventually systolic biventricular dysfunction; arrhythmia; and conduction defects. To the best of our knowledge, no previous cases of isolated tricuspid regurgitation as the initial manifestation of cardiac amyloidosis have been reported. We describe a rare case of cardiac amyloidosis that initially presented with severe tricuspid regurgitation in a 42-year-old woman who was successfully treated with tricuspid valve replacement. Unusual surgical findings prompted additional evaluation that established a diagnosis of plasma cell myeloma.

Traumatic tricuspid regurgitation is a rare complication of blunt chest trauma caused by chordal rupture, anterior papillary muscle rupture and anterior leaflet tear. Since clinical symptoms are vague, early diagnosis is difficult and some patient exhibit symptoms of right heart failure. Right heart failure has been the traditional indication for surgical treatment, such as tricuspid valve replacement. Recently, early detection using transthoracic echocardiography and surgical treatment, like valve repair, prior to overt right heart failure have been shown to better prognosis. We report a case of traumatic tricuspid regurgitation with chordal rupture in patient due to traffic accident.
