Objective To explore the evolving strategies and compare perioperative and long-term outcomes of tricuspid valve replacement (TVR) in recent 20 years in our hospital.MethodsBetween 1998 and 2018, the clinical data of 608 patients who underwent TVR at the Department of Cardiac Surgery, Guangdong Provincial People’s Hospital were retrospectively analyzed. There were 201 males and 407 females, with a median age of 47.0 (36.0, 57.0) years. Patients were divided into a biological tricuspid valve (BTV, n=427) group and a mechanical tricuspid valve (MTV, n=181) group. Propensity score matching was used to balance the baseline difference. Surgical strategy evolving, postoperative and long-term outcomes were analyzed between the two groups.ResultsSince 2008, the usage ratio of biological valves was significantly higher than that of mechanical valves. Seventy-nine (13.0%) patients died in hospital after TVR. Before propensity score matching, the postoperative mortality of the BTV group was higher than that of the MTV group (15.2% vs. 7.7%, P=0.012), and there was no statistical difference between the two groups after matching (10.4% vs. 7.2%, P=0.372). The duration of postoperative ventilator support in the BTV group was longer than that in the MTV group [22.0 (15.0, 37.0) h vs. 19.0 (11.0, 27.0) h, P=0.003], and the incidence of postoperative dialysis and re-thoracotomy exploring for bleeding was higher in the BTV group (8.9 % vs. 2.8%, 9.4% vs. 6.6%, respectively). However, there was no statistical difference in mortality after matching. The median follow-up time of discharged patients was 101.0 (65.0, 147.0) months, ranged from 1 to 265 months, and the follow-up rate was 82.2%. During the follow-up period, there were 101 deaths (19.1%) of whom 68 were from the BTV group and 33 from the MTV group. The survival rates at 1 year, 5 years, 10 years, 15 years and 20 years of all patients were 85.0% (95%CI 82.2-87.9), 78.9% (95%CI 75.7-82.4), 71.1% (95%CI 67.3-75.3), 59.7% (95%CI 54.2-65.6) and 51.7% (95%CI 43.3-60.7), and there was no statistical difference between the two groups after matching (P=0.46). The median time of tricuspid valve failure was 84.0 (54.0-111.0) months.ConclusionTVR is associated with high perioperative risks. There is no statistical difference in early mortality and long-term survival between biological and mechanical valve, while patients with mechanical valve has higher risk of re-operation for valve failure. Therefore, the type of prosthetic valve can be selected according to the patients' age, physical condition and the doctors’ experience.
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.
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.
A 23-year-old male patient was diagnosed with congenitally corrected transposition of the great arteries (ccTGA) at the age of 3 during a routine physical examination. Due to the absence of significant symptoms, the patient was managed conservatively with follow-up without surgical treatment. He developed chest tightness one year prior to admission, with symptom exacerbation in the recent month. Echocardiography demonstrated significantly worsened morphological tricuspid regurgitation. The patient presented to Guangdong Provincial People’s Hospital for surgical evaluation. Given the patient’s age and clinical presentation, a totally thoracoscopic morphological tricuspid valve replacement was performed. Postoperative assessment showed good prosthetic valve function, with no regurgitation or paravalvular leakage; the electrocardiogram confirmed sinus rhythm without atrioventricular block. Extubation occurred within 12 hours postoperatively, and the patient was transferred from the intensive care unit (ICU) on postoperative day 2. At the three-month follow-up, the patient was asymptomatic and had resumed normal activities. This report describes the first case of a totally thoracoscopic morphological tricuspid valve replacement in a ccTGA patient in China. This initial experience suggests that the totally thoracoscopic approach for morphological tricuspid valve replacement in ccTGA patients is a feasible, safe, and effective minimally invasive option associated with rapid recovery.
Functional tricuspid regurgitation is referred to tricuspid regurgitation due to enlargement of right ventricular and dilation of tricuspid annulus. Patients with chronic progressive tricuspid regurgitation have poor prognosis, poor quality of life and heavy economic burden. This article provides a comprehensive review of functional tricuspid regurgitation in terms of anatomical basis, pathological stage, imaging assessment and surgical decision making.
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.
This article reports a case of transjugular transcatheter tricuspid valve replacement (TTVR) for persistent severe tricuspid regurgitation after transcatheter mitral valve replacement. The patient was an 80 year old female who underwent transcatheter mitral valve replacement at the Department of Cardiology, West China Hospital, Sichuan University, two months before admission. After the surgery, her condition worsened due to unimproved tricuspid regurgitation and right heart failure. After admission, the patient underwent transjugular TTVR under general anesthesia. With the assistance of cardiac ultrasound and X-ray fluoroscopy, an artificial valve was successfully implanted, and tricuspid regurgitation was relieved. The patient’s surgery went smoothly, and the condition improved significantly 25 days after surgery. The patient was discharged 34 days after surgery.
Abstract： Objective To investigate the early and mid-term outcomes of morphologic tricuspid valve replacement by means of intravalvular implantation in corrected transposition of great arteries（cTGA）. Methods From January 2009 to January 2012，11 patients with cTGA were surgically treated in Fu Wai Hospital. There were 9 male patients and 2 female patients with their mean of age of（37.8±11.7）years and mean body weight of（73.0±11.3）kg. All the patients underwent morphologic tricuspid valve replacement with preservation of the entire valvular and subvalvular apparatus. Simultaneous surgical procedures included repair of ventricular septal defect in 2 patients，repair of atrial septal defect in 4 patients，pulmonary valvuloplasty in 1 patient，reconstruction of functional right ventricular outflow tract in 4 patients and repair of coronary-pulmonary artery fistula in 1 patient. Postoperative New York Heart Association （NYHA） classification, cardiothoracic ratio, morphological right ventricle ejection fraction, end-diastolic dimension of morphological right ventricle and left atrium were evaluated during follow-up. Results All the 11 patients were successfully surgically treated and followed up for an average duration of（13.0±10.6）months. There was no statistical difference between postoperative and preoperative average cardiothoracic ratio （0.54±0.06 vs. 0.57±0.09，t=1.581，P＞0.05），morphologic right ventricle ejection fraction （52.8%±9.0% vs. 54.9%±9.5%, t =0.712，P＞0.05），and end-diastolic dimension of . morphological right ventricle （54.3±7.5 mm vs. 56.9±9.2 mm，t =0.988，P＞0.05）. There was statistical difference between postoperative and preoperative average end-diastolic dimension of left atrium（42.1±8.9 mm vs. 53.4±11.1 mm，t =3.286，P＜0.05）and NYHA classification（Z = -2.640，P＜0.05）. Conclusion Intravalvular implantation of morphologic tricuspid prosthesis can protect the physiological structure of morphologic right ventricular and prevent furtherdamage to its function caused by morphologic tricuspid valve insufficiency. Postoperative dimension of morphologic left atrium and cardiac function are significantly improved. The early and mid-term outcomes are satisfactory．
