Abstract： Ebstein anomaly is a relatively rare congenital heart malformation which can affect heart function significantly. It may cause right heart failure, even whole heart failure and eventually death. In recent years, the surgery has made much progress in dealing with the abnormal valve, improving the right ventricle function and pretreatment of its related complications. However, because of its complexity and diversity in pathological anatomy and clinical manifestations, the disease has not got an “almighty standard” to treat all pathological anatomy types of the deformity, or asurgery strategy to solve the practical problems encountered in all clinic situations. Furthermore, the therapeutic effect is also unsatisfactory. This article will review the advance of treatment of Ebstein anomaly and prevention of its related complications.
Objective To analyze the medium-and long-term r esults of tricuspid valve replacement(TVR), to summarize the experience in opera tive therapy for tricuspid valve disease. Methods From January 1998 to May 2006, sixty seven patients had undergone TVR. The etiology was rheumatic disease in 25 cases, congenital disease in 37 cases, degenerative disease in 1 case, infective endocarditis in 3 cases, a nd cardiac tumor in 1 case. All operations were performed under general anesthes i a and by cardiopulmonary bypass. Bioprostheses was replaced in 28 patients, whil e mechanical valve was replaced in 39 patients. Associated procedure included mi tral valve replacement in 13 cases, mitral valve replacement and aortic valve replac ement in 12 cases, repair of ventricular septal defect in 1 case, repair of atri al septal defect in 1 case, and radioablation of atrial fibrillation in 3 case s. Results The operative mortality was 11.94% (8/67)，among these patients , 6 cases died of serious heart failure,1 case died of ventricular fibrillation, 1 case died of multi organ failure. During follow-up, 1 patient died of biopro thesis dysfunction 1 year after the operation, 1 patient died of cerebral emboli s m 6 years after the operation. Through statistical analysis, it showed that the mortality of TVR in rheumatic tricuspid valve disease was higher than that in co ngenital tricuspid valve disease ［5.56%（2/36）vs. 24.00% (6/25); χ2=4.425 , P=0.036］; the mortality in second time operation was higher than that in first time operation ［30.00%（3/10）vs. 8.77% (5/57);χ2=3.646，P=0.033 ］; while there was no significant difference in immediate and long-term result s with different choice of bioprosthetic or mechanical valve in TVR (χ2=0.002 , P=0.961). Conclusion Operative an d follow-up mortality is high in the TVR, valve replac ement is the last selection for the treatment of serious tricuspid disease, appr opriate operative technique and perioperative therapy is the key for success o f the operation.
Objective To evaluate the early and middlelongterm clinical results of tricuspid valve replacement (TVR) and compare the relative merit between bioprothesis and mechanical valve in tricuspid position，so as to elevate the operative effect. Methods The data of 128 TVR from April 1992 to February 2008 in An Zhen Hospital were retrospectively reviewed， and classified into mechanical prosthesis group（n=89）and bioprothesis group（n=39）according to the prosthesis used in the first procedure. Kaplan-Meier curve were estimated to evaluate the midlong term survival rate and events incidence related to prosthesis（including thrombosis, embolism and bleeding related to prosthesis and the prosthesis deterioration）. Multivariate binary logistic regressions were used to evaluate the independent risk factor for early and late death. Results There were 19 early deaths( 14.84%). With the followup of 4.93±2.92 years, there were 11 late deaths(10.7%). According to the Kaplan-Meier curve, the 10year actuarial survival rate for the bioprothesis group and mechanical prosthesis group were 65.6%±17.4% and 68.7%±10.8% respectively(Log-rank test,χ2=0.74，P=0.390). Freedom from prosthesis-related embolism at 5 years for the bioprothesis group and mechanical prosthesis group were 92.3%±7.4% and 87.1%±4.6% respectively(Log-rank test, χ2=0.962，P=0.327). Freedom from anticoagulationrelated bleeding at 10 years for the bioprothesis group and mechanical prosthesis group were 100% and 79.7%±9.7% respectively(Log-rank test, χ2=1.483，P= 0.223). There were 9 TVR reoperation, freedom from reoperation at 7 years for the bioprothesis group was 71.1%±18.0%, and freedom from reoperation at 10 years for the mechanical prosthesis group was 78.8%±10.2% (Log-rank test, χ2=2.76，P=0.096). Binary logistic regression revealed that the redo procedure and ascites were independent risk factors for early death, whereas ascites, heart function of New York Heart Association class Ⅲ/Ⅳ and multi valve replacement were independent risk factors for late death.Conclusion To lower the operative mortality and late mortality and morbidity, TVR should be adopted prior to the deterioration of right heart function, and bioprothesis valve has similar early and middlelong term clinical effect with mechanical valve in tricuspid position.
ObjectiveTo evaluate the long-term clinical effect and risk factors of tricuspid valve replacement (TVR) as a relief treatment for adult patients with congenitally corrected transposition of the great artery (CCTGA).Method We retrospectively analyzed the clinical data of 47 adult patients with CCTGA who underwent tricuspid valve replacement in Fuwai Hospital between 2000 and 2017 year. There were 27 males and 20 females with operation age of 14–62 (38.8±13.5) years. Preoperative echocardiography showed moderate or more tricuspid regurgitation in all patients. The basic data of patients before and during operation were recorded. Survival was followed up by telephone and ultrasound report.ResultsThe average follow-up time was 6.5±3.7 years. The 1-year, 5-year and 10-year survival rate or the incidence of heart transplant-free was 94.6%, 90.5% and 61.7%, respectively. During the follow-up period, the long-term right ventricular ejection fraction of most patients (>90%) was still greater than or equal to 40%. Increased preoperative right ventricular end diastolic diameter (RVEDD) was a risk factor for death or heart transplantation (risk ratio 1∶11, P=0.04). The survival rate of patients with RVEDD (>60 mm) before operation was significantly reduced (P=0.032).ConclusionTVP is a feasible treatment for adult patients with CCTGA. The increase of preoperative RVEDD is a risk factor for long-term mortality.
Abstract: Objective To summarize the clinical experience of 13 patients of tricuspid valve replacement and to investigate the indication and method. Methods From January 1994 to December 2005, the clinical datum of the thirteen patients suffering from tricuspid valve disease were reviewed, including rheumatic heart disease 6 cases, congenital heart disease 3 cases, infective endocarditis 3 cases and right ventricular tumor 1 case. All the cases underwent tricuspid valve replacement. Results Two reoperative rheumatic heart disease patients died early after operation and their cardiac function was New York Heart Association (NYHA) class Ⅳ before operation. The followup interval was 3 months to 12 years in 11 cases. There were 2 late death, one died of recurrence of infective endocarditis, and another died of the recurrence of the tumor. One Ebstein anomaly case’s NYHA functional recovered to class Ⅲ, eight cases’s recovered to NYHA classⅠ-Ⅱ. Conclusion The tricuspid valve disease may be a secondary lesion from many causes. Indication of tricuspid valve replacement must be strictly commanded. The late results of tricuspid valve mechanical prostheses replacement is satisfactory.
Tricuspid valve, also known as "forgotten valve" because of the high natural and surgical mortality. Transcatheter tricuspid valve replacement is an innovative surgical method to treat tricuspid regurgitation, which improves the prognosis of patients and is gradually being popularized in clinics. However, postoperative pulmonary complications are still the main causes affecting the rapid recovery and death. More and more medical experts begin to use preoperative inspiratory muscle training to reduce postoperative pulmonary complications and improve the quality of life of patients after cardiac surgery. However, there was no report on the effect of preoperative inspiratory muscle training on pulmonary complications after transcatheter tricuspid valve replacement. Therefore, for the first time, we boldly speculate that inspiratory muscle training can reduce pulmonary complications after transcatheter tricuspid valve replacement, and put forward suggestions for its treatment mechanism and strategy. But this rehabilitation intervention lacks practical clinical research. Unknown challenges may also be encountered, which may be a new research direction.
Objective To summarize the clinical characteristics and management experiences of patients with severe tricuspid regurgitation (TR) after mitral valve surgery. Methods Thirty patients were followed up and reviewed for this report. There were 1 male and 29 female patients whose ages ranged from 32 to 65 years (47.1±92 years). A total of 28 patients had atrial fibrillation and 2 patients were in sinus rhythm. There were 13 patients of mild TR, 10 patients of moderate TR and 7 patients of severe TR at the first mitral valve surgery. Five patients received the tricuspid annuloplasty of De Vega procedure at the same time, 2 patients received Kay procedure. The predominant presentation of patients included: abdominal discomfort (93.3%, 28/30), edema (66.7%,20/30), palpitation (56.7%, 17/30), and ascites (20%, 6/30). Results Nine patients underwent the secondary surgery for severe TR. The secondary surgery included tricuspid valve replacement (6 cases), mitral and tricuspid valve replacement (2 cases) and Kay procedure (1 case). Eight patients were recovered and discharged and 1 patient died from the bleeding of right atrial incision and low output syndrome. Twentyone patients received medical management and were followed up. One case was lost during followup. Conclusion Surgery or medical management should be based on the clinical characteristics of patients with severe TR after mitral valve surgery. It should be based on the features of tricuspid valve and the clinical experience of surgeon to perform tricuspid annuloplasty or replacement.
