Abstract： Tricuspid insufficiency founded in the setting of left-sided heart disease is usually secondary tricuspid insufficiency caused by tricuspid valve annular dilation. Some patients had rheumatic tricuspid valve diseases. Tricuspid valve repair rather than valve replacement is recommend for functional tricuspid regurgitation. Linear annuloplasty and ring annuloplasty are two main tricuspid valve repair methods. However, the indications for treatment of secondary tricuspid regurgitation remain controversial. The optimal surgical repair technique to eliminate secondary tricuspid regurgitation remains challenging. In this article, we review the assessment of tricuspid valve lesions, criteria for correction, and surgical management of secondary tricuspid insufficiency.methods. However, the indications for treatment of secondary tricus
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 investigate effect of cardiac function and tricuspid regurgitation (TR) degree of concomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent mitral valve replacement (MVR), and provide an objective basis for clinical decision about concomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent MVR. MethodsA total of 36 patients who underwent MVR from April to October 2013 in Department of Cardiovascular Surgery, West China Hospital, Sichuan University were enrolled in this study. Preoperative echocardiography showed mild TR and tricuspid valve annular end-diastolic dimension (TVAEDD)/body surface area (BSA)>21 mm/m2. All the 36 patients were randomly divided into a tricuspid annuloplasty group (TAPG group, n=18, including 7 males and 11 females) and a no tricuspid annuloplasty group (NTAPG group, n=18, including 6 males and 12 females). One week and 6 months postoperative echocardiography were recorded. ResultsThere were no statistical differences in age, gender, heart rate, body surface area, preoperative cardiac function (NYHA), left atrium dimension (LAD), left ventricular dimension (LVD), maximal long-axis of RA (RAmla), mid-RA minor distance (RAmmd), right ventricle dimension (RVD2), left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) between the two groups (P>0.05). Six-months postoperative left atrial-ventricular diameter significantly reduced than that before surgery in the two groups (P<0.05). In the TAPG group, six-months postoperative right ventricle dimension (RVD1), right ventricular wall thickness (RVWT), tricuspid valve annular end-diastolic dimension (TVAEDD), tricuspid valve annular end-systolic dimension (TVAESD) significantly decreased, while percent shorting of tricuspid valve annulus (PSTVA) did not change significantly (P>0.05), TR degree improved significantly (P<0.05), right ventricular fractional area change (RVFAC) and right ventricular ejection fraction (RVEF) significantly increased (P<0.05). In the NTAPG group, compared with preoperative data, six-months postoperative RVD1, RVWT significantly increased, TVAEDD, TVAESD, PSTVA did not change significantly (P>0.05), RVEF reduced significantly (P<0.05), RVFAC increased significantly but less than that in the TAPG group at the same period, constituent ratio of TR changed significantly (P<0.05), but postoperative moderate or more TR were recorded in 6 patients. ConclusionConcomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent mitral valve replacement (MVR) can help to decrease RVD1, RVWT, TVAEDD and TVAESD, improve the constituent ratio of TR, and increase RVFAC and RVEF.
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.
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.
Objective To evaluate the right ventricular function of the patients 2 years after surgery by ultrasonic cardiography (UCG) who underwent mitral valve replacement (MVR) concomitant tricuspid annuloplasty (TAP). Method We finally identified 36 patients required MVR with tricuspid valve annular dilation concomitant merely mild tricuspid regurgitaion (TR) based on preoperative UCG in our hospital between April and November 2012 year. All patients were randomly divided into two groups by digital table including a tricuspid annuloplasty group (a TAP group, n=18, 7 males and 11 females at age of 45.67±12.49 years) and a no-tricuspid annuloplasty group (a NTAP group, n=18, 6 males and 12 females at age of 45.44±10.48 years). General clinical data and extracorporeal circulation data were recorded. UCG evaluation was practiced preoperation, alone with 1 week, 6 months, and 2 years after surgery. Results Two years postoperative maximal long-axis of RA (RAmla), mid-RA minor distance (RAmmd), right ventricle dimension-1(RVD1) , right ventricular fractional area change (RVFAC), 3D RV end-systolic volume (3DRVESV), tricuspid valve annular end-diastolic dimension (TVAEDD), tricuspid valve annular end-systolic dimension (TVAESD) of patients were all smaller in the TAP group than those in the NTAP group. Yet right ventricular ejection fraction (RVEF), percent shorting of tricuspid valve annulus (PSTVA) were greater in the TAP group than those in the NTAP group, although there was no statistical difference between the two groups in two years postoperative 3D RV end-diastolic volume (3DRVEDV). The patients in the TAP group had a superior trend than that of the NTAP group. Moreover, the patients' TR constituent ratio in the TAP group was much better than that of the NTAP group in 2 year after operation. Conclusions Concomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent MVR is favorable for the recovery of their 2 years postoperative function of tricuspid valve and right ventricle. It is benefit to reduce patient's long term postoperative TR residues and exacerbation.
ObjectiveTo compare the outcomes of concomitant mitral valve surgery and tricuspid valve surgery through right minithoracotomy and conventional median sternotomy approaches. MethodsWe retrospectively analyzed clinical data of 475 patients underwent mitral valve surgery combined with tricuspid valve surgery through right minithoracotomy or conventional median sternotomy in Xinhua Hospital between June 2006 and June 2013. The patients were divided into two groups including a minimally invasive group(116 patients) and a conventional group (359 patients). ResultsAll the patients successfully underwent mitral valve and tricuspid valve surgery. During operation, there were 426 patients with no trivial mitral regurgitation (MR) and 49 patients with trivial MR. There were 282 patients with no tricuspid regurgitation (TR) and 193 patients with trivil TR. At discharge, transesophageal echocardiography showed that trivial MR in 38 patients, mild MR in 5 patients, trivial tricuspid regurgitation (TR) in 150 patients and mild TR in 7 patients. There was no significant difference between the two groups in complications. ConclusionRight minithoracotomy can achieve the similar therapeutic effect to conventional median sternotomy for patients with mitral valve disease and concomitant tricuspid valve disease. In addition, patients through right minithoracotomy had better cosmetic outcomes.
Functional tricuspid valve regurgitation (TR) is often secondary to left-sided valvular heart diseases. The precise diagnosis of TR degree and reasonable treatment can improve the long-term prognosis of patient. Now we believe that rectifying the TR during left cardiac valve surgery can prevent a further development of TR and avoid the reducing of the cardiac function for patients with moderate TR, tricuspid valve annulus diameter>40 mm in late diastole, tricuspid valve diameter/body surface area>21 mm/m2, and intraoperative tricuspid valve diameter >70 mm, especially for patients with atrial fibrillation and atrial enlargement. The use of prosthetic ring can effectively prevent recurrence of TR in long term and we should try to use hard or semihard "C" shape prosthetic ring as much as possible. The tricuspid valve replacement should be avioded because of its higher mortality.
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.
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.
