Aortic and tricuspid valve replacement in a case of corrected transposition of the great arteries

It is well known that corrected transposition of the great arteries (C-TGA) is accompanied with tricuspid valve regurgitation, but very few reports have described complication of this anomaly with aortic valve regurgitation (AR). We have performed aortic valve replacement (AVR) in a case of C-TGA associated with AR which had been evaluated the grade of 3/4 according to Sellers' classification, simultaneously done the valve replacement for the dysplastic tricuspid valve and annuloplasty for the right-side atrioventricular valve (mitral valve). The patient has a favorable postoperative course.     

Management of quadruple valves for severe infective endocarditis; report of a case

A 74-year-old man had pustulant bilateral arthritis complicated with sepsis and disseminated intravascular coagulation (DIC). Microbiologic study of blood sample showed Streptococcus and methicillin resistant Staphylococcus aureus (MRSA). He was complicated with postulant diskitis since then. Medical treatment for DIC and administration of antibiotics were performed. Preoperative echocardiography revealed massive aortic regurgitation and vegetation of aortic valve, moderate pulmonary regurgitation and vegetation of pulmonary valve, massive mitral regurgitation, massive tricuspid regurgitation. He was diagnosed as infective quadruple valve endocarditis. He received aortic valve replacement, pulmonary valve replacement, mitral valve repair and tricuspid valve repair. Postoperative echocardiography showed satisfactory function of bioprosthesis. Postoperative course was uneventful.     

Anticoagulation therapy and circulatory management with left ventricular catheter under left ventricular bypass using centrifugal pump--an experience in a case with mitral valve replacement

A 53-year-old woman who had severe mitral regurgitation associated with moderate tricuspid regurgitation and mild aortic regurgitation underwent mitral valve replacement with a 27 mm Bj?rk-Shiley mechanical valve, left atrial plication and tricuspid annuloplasty. She fell into low output syndrome on the first postoperative day because of persistent intractable ventricular arrhythmia and eventually required open cardiac massage. The left ventricular (LV) bypass using a centrifugal pump was initiated with cannulation to ascending aorta and left atrium. Echocardiography showed LV wall motion extremely poor with the prosthetic valve being in closed posture. For prevention from thrombus formation on the prosthetic valve and in the LV, a catheter was inserted into LV through RV to give heparin and monitor the LV pressure. As the result, activated clotting time of LV was higher (range from 280-388 sec) than that of systemic blood (range from 182-258 sec). Also, the change of LV pressure was monitored through this LV catheter. Under this monitor, IABP was smoothly applied in the presence of aortic regurgitation, and she was weaned from LV-bypass successfully after 157 hrs support. She was discharge on the 77th postoperative day without thromboembolic complication.     

Tricuspid regurgitation in patients with acquired, chronic, pure mitral regurgitation. II. Nonoperative management, tricuspid valve annuloplasty, and tricuspid valve replacement

The incidence, preoperative and intraoperative diagnosis, methods, and the clinical and hemodynamic features of patients with and without tricuspid regurgitation associated with chronic mitral regurgitation were presented in Part I. This study (Part II) compares the early and late results in patients with chronic, pure mitral regurgitation undergoing isolated mitral valve replacement, mitral replacement and tricuspid valve annuloplasty, and mitral and tricuspid valve replacement. The mean follow-up interval was 6 years. Those with the longest duration of symptoms (18 years) required tricuspid and mitral valve replacement (11 patients), whereas those with the shortest duration (8.1 years) had only mitral replacement (22 patients). Eight patients had minimal tricuspid regurgitation by digital palpitation, with no procedure performed, and six had tricuspid valve annuloplasty, only one of whom received a ring support. Operative mortality rate was similar in all groups (13% to 18%). All but two of the surviving patients improved by at least one New York Heart Association functional class, and no statistically significant differences were found between preoperative and postoperative hemodynamic data. There were no statistically significant differences in survival at 1, 5, or 8 years (85%, 70%, and 60%, respectively) for patients with or without TR. Only two of the surviving five patients who underwent tricuspid valve annuloplasty were alive 3 years after operation, whereas 70% to 80% of those with mitral replacement or mitral and tricuspid replacement were alive after the same time interval. It is not clear whether or not the pathogenesis of tricuspid regurgitation resulting from mitral regurgitation is different from that of tricuspid regurgitation resulting from mitral stenosis. It is our contention that whether tricuspid regurgitation arises because of anatomic destruction of the tricuspid valve or because of right ventricular dilatation with tricuspid annular enlargement, the underlying mitral valve lesion may determine the preoperative and postoperative courses of these patients. Therefore, when tricuspid valve disease is being evaluated, we urge that patients be categorized by the nature of their underlying mitral or aortic valve lesions.     

Reoperation for a patient 25 years after a Starr-Edwards ball mitral valve was installed.

A 45-year-old female suffered from increasing dyspnea during exercise and edema of lower extremities from January 2000. She had undergone mitral valve replacement with Starr-Edwards ball prosthesis (model 6320) due to mitral valve regurgitation 25 years ago. The cardiac catheterization and echocardiography documented mitral, aortic and tricuspid valves regurgitation grade III. Left ventricular ejection fraction rate was 49% and the pressures of CVP, RA, RV and PA were also increased. Laboratory examination showed slight hemolytic anemia. Double valve replacement (ATS valve) and tricuspid annuloplasty were carried out in April 2000. Strut cloth wear was confirmed at operation. Her postoperative course was uneventful. We hereby review the published paper of all cases with an implanted Starr-Edwards ball valve who required redo valve replacement with over 15 years follow-up. We consider that cloth injury is the main cause for reoperation and it usually associated with hemolytic anemia; cloth wear not only involves the aortic position but also frequently involves the mitral position for over 15 years follow-up patients and can be corrected by reoperation. Cloth wear should be concerned for those surviving patients who have received the Starr-Edwards ball valve during long-term follow-up.     

Hemolytic anemia due to aortic valve regurgitation after mitral valve replacement

A 50-year-old woman was admitted to our hospital because of heart failure (NYHA III) due to mitral valve regurgitation (MR) with pulmonary hypertension (PH) and tricuspid valve regurgitation (TR). She had a history of chronic renal failure undergoing dialysis (peritoneal dialysis, homodialysis) since 1996. Cardiac catheterization and ultrasonic cardiography showed severe MR (Sellers III), severe TR and PH (mean pressure 33 mmHg). So we performed mitral valve replacement and tricuspid annuloplasty (DeVega). Frequent blood transfusion was needed because severe hemolytic anemia appeared after operation. Ultrasonic cardiography demonstrated moderate aortic valve regurgitation (AR) with no paravalvular prosthetic leakage. We diagnosed hemolytic anemia due to AR. We performed aortic valve replacement. Hemolytic anemia improved soon after second operation. We investigated the mechanical process of the AR. She had a very short subaortic curtain (5.9 mm) compared with the average (8.7 +/- 2.1 mm: mean +/- SD) of cardiac patients. We think that we must be very careful with suture to short subaortic curtain. In addition measurement of subaortic curtain before operation is very useful.     

A prosthetic ring annuloplasty with edge-to-edge repair for a treatment of severe tricuspid regurgitation

A 59-year-old woman admitted to our hospital with shortness of breath and edema of the lower extremities was diagnosed with right ventricular failure stemming from severe tricuspid valve regurgitation (TR). She had undergone mitral valve replacement (MVR) with a mechanical valve at the age of 42. The approach to the heart was established via a right thoracotomy at the 4th intercostals space. A beating heart cardiopulmonary bypass procedure was performed in which tricuspid valve repair was performed with the edge-to-edge repair and MC3 annuloplasty system. The operative course was uneventful. This technique may be feasible and clinically effective in the treatment of severe TR.     

A case of Bentall's operation for an 11-year-old patient with Marfan syndrome

An 11-year-old girl who was diagnosed to have Marfan syndrome in her infancy, visited us with complaints of easy fatigability and chest discomfort. She was pointed out to have acute development of annuloaortic ectasia with severe aortic regurgitation and mild mitral regurgitation. She underwent replacement of the ascending aorta and aortic valve using composite graft with prosthetic valve (Bentall's operation) and circular annuloplasty of the mitral valve. Bentall's operation for infants and children is remarkably rare because in this generation, acute development of aortic dilatation leading rupture and dissection is quite infrequent while main death is caused by mitral regurgitation.     

A case of aortic prosthetic valve endocarditis with aortic root aneurysm

A 72-year-old male who underwent patch closure of atrial septal defect and aortic valve replacement (AVR) 10 years ago was diagnosed as aortic prosthetic valve endocarditis for recurrent fever, coexisting paravalvular leakage and aortic root aneurysm by transthoracic and transesophageal echocardiography. Operative findings showed mechanical prosthesis was dehiscenced in part and limited subannular aneurysm that was healed macroscopically. The hole of the aneurysm was closed by direct suture. Re-AVR, mitral valve replacement and tricuspid annuloplasty for complicating mitral valve stenosis and regurgitation and tricuspid valve regurgitation was performed. The patient is now doing well for one year after the reoperation.     

A case of aortic prosthetic valve endocarditis with aortic root aneurysm]

A 72-year-old male who underwent patch closure of atrial septal defect and aortic valve replacement (AVR) 10 years ago was diagnosed as aortic prosthetic valve endocarditis for recurrent fever, coexisting paravalvular leakage and aortic root aneurysm by transthoracic and transesophageal echocardiography. Operative findings showed mechanical prosthesis was dehiscenced in part and limited subannular aneurysm that was healed macroscopically. The hole of the aneurysm was closed by direct suture. Re-AVR, mitral valve replacement and tricuspid annuloplasty for complicating mitral valve stenosis and regurgitation and tricuspid valve regurgitation was performed. The patient is now doing well for one year after the reoperation.     

Enlarged coronary sinus thrombosis after repair of Ebstein's anomaly

A 58-year-old woman was referred to our hospital with progressively increasing breathlessness. She reported a history of bioprosthetic valve implantation for tricuspid valve replacement and direct closure of an atrial septal defect for Ebstein's anomaly, 31 years before presentation. Transthoracic echocardiography revealed prosthetic valve failure, an enlarged coronary sinus, and severe mitral regurgitation. Computed tomography revealed a giant coronary sinus with thrombosis and persistent left superior vena cava. She underwent successful mitral and tricuspid valve replacement; however, severe hemodynamic deterioration necessitated mechanical ventilatory support with extracorporeal membrane oxygenation.     

Surgery for the valvular disease in children

We report the results and long-term follow up in 34 children (17 girls and 17 boys, aged 12 days to 13 years, average age 3.3 years, average body weight 11.7 kg) who underwent valvular surgery in the period between May 1989 and November 1996. Operative mortality was 11.8%. Actuarial survival curves (including hospital mortality) indicate a 68.6% survival rate at 5 years and that 64.7% of patients are free from reoperation at 5 years. For aortic regurgitation two patients applied aortic valvuloplasty and four applied aortic valve replacement. Nine children had aortic stenosis, three of them had balloon valvuloplasty, seven had valvotomy, two had aortic valve replacement. Ten patients were treated for mitral regurgitation. There were nine valvuloplasty and four mitral valve replacement including three times of reoperation. One membranous pulmonary atresia and seven pulmonary stenosis children had valvotomy. There were four cases of tricuspid disease. One had tricuspid valve stenosis with pulmonary stenosis, three had severe tricuspid regurgitation who applied tricuspid valve replacement. Mortality was high in the critical AS, severe MR and TVR groups. Patients who survived the surgery and had no complications showed satisfiable results.     

True Aneurysm of the Left Main Trunk in a Marfan Syndrome Patient at Remote Period after Bentall Operation and Total Arch Replacement: A Case Report

In 2002, a 37-year-old male with Marfan syndrome underwent the Bentall operation, total arch replacement, and aortobifemoral bypass for DeBakey type IIIb chronic aortic dissection, annuloaortic ectasia, and aortic regurgitation. In 2007, mild mitral regurgitation (MR) caused by mitral valve prolapse was identified. In April 2017, echocardiography revealed the worsening of MR and moderate tricuspid regurgitation (TR). Moreover, coronary angiography (CAG) revealed a coronary artery aneurysm in the left main trunk (LMT). In August 2017, the patient underwent mitral valve replacement (MVR), tricuspid annuloplasty (TAP), and coronary artery reconstruction. We reconstructed the LMT aneurysm using an artificial graft. True aneurysm of the coronary artery complicated with Marfan syndrome is a rare complication that has seldom been reported. This case highlights that it is essential to carefully follow-up patients with Marfan syndrome after the Bentall operation.

Mechanical valve thrombosis in the tricuspid position--reoperative management of 2 cases

Because valve thrombosis occurred after the tricuspid valve replacement with the mechanical valve, we performed replacement of the mechanical valve with the bovine pericardial valve in two cases. Case 1: The patient, at 13 years old, received open-heart surgery to correct infundibular stenosis. At 23 years of age, decortication and tricuspid valve replacement (TVR) with a phi 31 mm Bj?rk-Shiley valve were performed due to constrictive pericarditis and tricuspid regurgitation developed after the initial operation. Thrombosis of the mechanical valve occurred after the TVR. Treatment with urokinase for the thrombolytic therapy failed to improve the valve opening. Finally 12 years after the TVR, replacement of the mechanical valve with a phi 27 mm Carpentier-Edwards bovine pericardial valve was performed. Case 2: The patient, at 21 years old, received open-heart surgery to close an atrial septal defect. At 40 years of age, mitral and tricuspid valve replacements were performed because regurgitation developed in both valves. The mitral and tricuspid valves were replaced with phi 27 mm and 31 mm St. Jude Medical valves, respectively. Thrombosis of the mechanical valve used for the TVR occurred 2 months after the replacement. The mechanical valve was replaced with a phi 27 mm Carpentier-Edwards bovine pericardial valve. In both cases, subjective symptoms improved and prosthetic valve complications did not occur after re-replacement with the bovine pericardial valve. These cases suggested that for TVR a bovine pericardial valve of sufficient size would be better to select than a mechanical valve.     

Valve-on-valve technique for replacement of degenerated tricuspid bioprosthetic valve without explantation

A 73-year-old woman admitted to our hospital with shortness of breath and edema of the lower extremities was diagnosed with right ventricular failure stemming from tricuspid valve regurgitation. She had undergone mitral valve replacement (MVR) with a mechanical valve at the age of 51, and reoperative MVR with mechanical valve, tricuspid valve replacement (TVR) with bioprosthetic valve, and pacemaker implantation at the age of 63. Reoperative TVR was performed when the patient failed to respond to drug therapy. A beating heart cardiopulmonary bypass procedure was performed in which only the bioprosthetic valve leaflet was excised, and reoperative TVR was performed with a 27-mm OptiForm^TM mechanical mitral valve (Sulzer Carbomedics Inc., Austin, TX, USA) by the valve-on-valve technique. The operative course was uneventful. The technique used here appears to be an effective approach to reoperative TVR, in this instance making it possible to avoid the risks associated with excision of the old prosthesis.     

Long-term results of DeVega tricuspid annuloplasty

DeVega tricuspid annuloplasty was performed in 74 patients undergoing mitral or mitral and aortic valve replacement between January, 1972, and December, 1985. Sixty-two hospital survivors have been followed up for a mean of 85.3 +/- 6.6 months. Actuarial survival at 14 years was 71.5 +/- 8.2%. None of the late deaths was related to the tricuspid annuloplasty. Three patients required tricuspid valve replacement for recurrence of tricuspid regurgitation (0.68% per annum). Eleven asymptomatic patients studied hemodynamically at a mean period of 53 months after the operation showed maintenance of the hemodynamic improvement. We recommend DeVega annuloplasty as the method of choice for moderate to severe tricuspid regurgitation in the absence of an organically diseased or deformed valve.     

Aortic and mitral valve replacement for calcified valvular annulus in a dialysis patient; report of a case

A 77-year-old man on hemodialysis was admitted to our hospital due to heart failure. Echocardiography showed aortic valve stenosis and regurgitation, mitral valve stenosis and regurgitaion, and tricuspid valve regurgitation. Catheter examination revealed severe calcification at aortic valve and mitral valve including their annulus. At the operation, the calcifications of the aortic and mitral valvular annulus was removed using a cavitron ultrasonic surgical aspirator (CUSA). Reconstructions of the defect of the posterior part of the mitral annulus and of the aortic annulus at the site of the left coronary cusp were achieved by patch technique using autologous pericardium. Aortic and mitral valve replacement and tricuspid valve annuloplasty were performed. The postoperative course was uneventful. Operative technique to remove calcification from valvular annulus using CUSA and reconstruct of the defect of the annulus with autologous pericardium is a very useful technique to prevent left ventricular rupture, perivalvular leakage and any other complications.     

Immediate and long-term outlook for valve replacement in acute bacterial endocarditis.

The clinical course of 22 patients with acute endocarditis treated surgically less than six weeks after the onset of antibiotic therapy was reviewed. The aortic valve was infected in 13 patients, the mitral in six, the tricuspid in two, and one patient had both aortic and mitral valve involvement. The indications for surgical intervention before the completion of adequate antibacterial therapy included uncontrollable congestive heart failure, persistent sepsis, systemic embolization, and multiple septic pulmonary embolizations. The annulus was involved by the infectious process in five of the 13 patients with aortic valve endocarditis, in one of the two patients with tricuspid valve infection, and in none of the patients with mitral valve endocarditis. There were two surgical deaths, for a mortality of 9.1%. During the follow-up period, four patients died three months, seven months, four years, and seven years after surgery. The remaining patients have been followed up for a period of five months to 10 years. One patient has a hemodynamically insignificant paravalvular leak, and another developed paravalvular regurgitation and a false aneurysm of the left sinus of Valsalva two weeks after the initial operation. She subsequently underwent successful valve replacement and repair of the aneurysm. This study confirms that valvular replacement should be done for acute endocarditis as soon as indicated, and that the incidence of reinfection and/or the development of valvular or paravalvular problems is small even in the patients with incomplete antimicrobial therapy, whether or not the annulus is involved by the infectious process.     

Acceleration of aortic regurgitation due to localized aortic dissection; report of a case

We successfully treated a patient with accelerated aortic regurgitation due to localized aortic dissection with mitral regurgitation causing congestive heart failure. A 58-year-old female, who had suffered from aortic regurgitation for more than 10 years, had acute heart failure due to acceleration of aortic regurgitation. The surgical findings showed prolapse of the aortic valve due to localized dissection in the sinus of Valsalva. We performed a Bentall operation and a mitral valve replacement, with a favorable outcome. The postoperative course was uneventful.
