Methods: From December 2007 to March 2009, 29 patients were treated with tricuspid valve annuloplasty. These were 16 patients in modified De Vega annuloplasty group and the others (13 patients) in traditional De Vega annuloplasty group. The grade of tricuspid regurgitation、New York Heart Association (NYHA) functional class、ejection fraction (EF) and the right ventricular enddiastolic dimension of two groups were followed and reviewed. Results: There was no statistically difference between two groups about preoperative characteristics and followup time. There was 1 patient with severe TR, 5 patients with moderate TR, 5 patients with mild TR and 2 patients without TR in traditional De Vega annuloplasty group after the operations. In modified De Vega annuloplasty group, no patient was observed with severe or moderate TR, 8 patients with mild TR, and 8 patients without TR. At interval time, there was significant difference in the grade of tricuspid regurgitation between two groups (Plt;0. 05). Both tricuspid valve plasty techniques could reduce the right ventricular enddiastolic dimension and improve ejection fraction significantly (Plt; 0. 05), and there was significant difference in the right ventricular enddiastolic dimension and ejection fraction at interval time between two groups (Plt;0.05). Conclusions: The outcome of modified tricuspid De Vega technique is superior to that of traditional De Vega technique in correcting severe tricuspid regurgitation.
Abstract: Objective To explore whether clinically mild functional tricuspid regurgitation should be addressed at the time of mitral valve repair (MVP) for moderate or severe mitral regurgitation due to myxomatous degeneration. Methods We retrospectively analyzed the outcomes of 135 patients with moderate or severemitral regurgitation due to myxomatous degeneration with mild functional tricuspid regurgitation. All patients were treated between January 1993 and March 2008 in the Department of Cardiothoracic Surgery of Changhai Hospital, the Second Military Medical University. We divided the patients into a MVP group (n=76) and a MVP+tricuspid valvuloplasty (TVP) group(n=59) according to whether they underwent combined TVP, and observed the perioperative mortality rate, degree of tricuspid regurgitation, and compared survival rate, and freedom from longterm moderate or severe tricuspid regurgitation after operation. Cox regression was used to analyzethe risk factors for longterm moderate or severe tricuspid regurgitation after operations. Results (1) There were no deaths during the perioperative period, and postoperative transthoracic echocardiography of all patients indicated that tricuspid regurgitation was mild or less. (2) Survival rate at 5 years, 10 years after operations in MVP group was 98.4%, 95.0%, respectively, and survival rate at 5 years, 10 years after operations in MVP+TVP group was 100.0%, 93.7%, respectively, and there was no significant difference in the survival rate after operations between the two groups(P=0.311), butthere was a significant difference in the freedom from longterm moderate or severe tricuspid regurgitation after operations between the two groups (P=0.040). Multivariate Cox regression showed that preoperative pulmonary artery pressure gt;30 mm Hg (95%CI 1.127 to 137.487, P=0.040 )and atrial fibrillation (95%CI 1.177 to 23.378, P=0.030) wereindependent risk factors for longterm moderate or severe tricuspid regurgitation afteroperations.Conclusion TVP is necessary for most patients undergoing MVP for moderate or severe mitral regurgitation due to myxomatous degeneration who have coexistent mild functional tricuspid regurgitation, especially those patients with preoperative pulmonary artery pressure gt;30 mm Hg or atrial fibrillation.
Abstract： Surgical repair of functional tricuspid regurgitation (FTR) is often carried out concomitantly with other leftsided heart valve procedures. Though diseases of both left heart valve and tricuspid were treated during the surgery, postoperative residual or recurrent tricuspid regurgitation has been clearly associated with progressive heart failure and worsened longterm survival. To date, surgical interventions mainly address FTR at three anatomic levels: commissure, annulus and leaflets. However, a certain mid and longterm failure rate after operation still exists. High surgical mortality rates have been reported in patients with recurrent tricuspid regurgitation requiring complex reoperations. With a better understanding of tricuspid anatomical complex and valvuloplasty, significant improvements have been made in FTR surgical indications and techniques. This review article will focus on the development of surgical indications in tricuspid valve repair, while the repair techniques and their impact on longterm clinical outcome will also be compared.
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.
Right-sided cardiac valvular diseases have traditionally been considered less important than disease of mitral or aortic valve. However, severe tricuspid regurgitation could lead to right ventricle dysfunction and reduce patients' survival rate. In clinic setting, tricuspid valve disease should be paid more attention for patients with secondary tricuspid regurgitation caused by left-sided valvular surgery combined with irreversible annular dilatation increasing the risk of re-operation. In this review, we summarize the epidemiology, anatomy, pathology, diagnosis, ultrasound and cardiac magnetic resonance imaging findings in patients with tricuspid regurgitation.
ObjectiveTo analyze the assessment and maintenance of 125 donor hearts from brain death donation and explore the use of marginal donor hearts.MethodsA retrospective analysis was conducted on the evaluation, maintenance, operation and follow-up results of 125 donor hearts from April 2016 to August 2019. There were 98 males and 27 females at age of 6-50 (36.0±2.4) years.ResultsTwelve donor hearts were discarded due to unqualified evaluation after heart harvest. 113 patients of heart transplantation were performed with a double lumen venous anastomosis manner. The mean time of cold ischemia was 220.1±6.7 min. Four patients died within 30 days after operation. Postoperative right ventricular assist circulation was performed in 4 patients, intra-aortic balloon counterattack (IABP) in 12 patients and extracorporeal membrane oxygenation (ECMO) in 12 patients. Marginal donors included 15 hepatitis B antigen positive donor hearts, 2 tricuspid regurgitation, 1 mitral regurgitation, 5 coronary calcification, 4 myocardial stunning and 2 severe weight mismatch. The results of follow-up (2 years) after marginal donor heart transplantation were satisfactory.ConclusionImproving the assessment and maintenance of donor hearts can improve the utilization rate of the heart, and the marginal donor heart transplantation needs long-term follow-up.
With the prevalence of atrial fibrillation and the increasing use of intracardiac pacemakers, the incidence of isolated tricuspid regurgitation is gradually increasing. Severe isolated tricuspid regurgitation has a seriously negative effect on the survival rate and life quality of patients. As the major invasive therapy, surgery is not routinely carried out due to high perioperative mortality. This article attempts to summarize the etiology, natural course and adverse consequences of isolated tricuspid regurgitation, current treatment strategies, surgical indications and techniques, efficacy evaluation, prognostic factors and transcatheter treatment progress of isolated tricuspid regurgitation, aiming to provide references for cardiologists and further researches.
ObjectiveTo analyze the clinical efficacy of right minithoracotomy approach in the treatment of patients with regurgitation after left-sided valve surgery (LSVS).MethodsThe clinical data of 77 patients who suffered tricuspid regurgitation (TR) after LSVS and received surgical treatment in the Heart Center of Henan Provincial People's Hospital from 2012 to 2019 were selected. According to the operation method, the patients were divided into a right minithoracotomy group (n=32), including 13 (40.6%) males, aged 57.3±5.3 years and a median sternotomy group (n=45), including 17 (37.8%) males, aged 55.7±6.6 years. Preoperative and postoperative clinical data of the two groups were compared and analyzed.ResultsThere was no significant difference in preoperative data between the two groups. There were 24 patients of tricuspid valvuloplasty (TVP) and 8 patients of tricuspid valve replacement (TVR) in the right minithoracotomy group. There were 29 patients of TVP and 16 patients of TVR in the median sternotomy group. The operation time, postoperative hospitalization time, intubation time and ICU stay time of the right minithoracotomy group were shorter than those of the median sternotomy group (P<0.001). The operative bleeding, postoperative drainage in 24 hours, postoperative blood transfusion rate and incision poor healing of the right minithoracotomy group were significantly decreased compared with those of the median sternotomy group (P<0.05). The extracorporeal circulation time between the two groups was not significantly different (P=0.382). The postoperative complications and mortality of the righ minithoracotomy group were significantly lower than those of the median sternotomy group (P<0.05).ConclusionThe procedure of right minithoracotomy access can reduce perioperative morbidity and mortality compared with the median sternotomy, and results in satisfied clinical efficacy.
ObjectiveTo investigate the morbidity of postoperative pulmonary complications (PPCs) in patients after transcatheter tricuspid valve replacement (TTVR). MethodsA prospective cohort study enrolled 19 patients who were diagnosed with severe or greater tricuspid regurgitation in West China Hospital from October 11, 2020 to March 1, 2021, and would receive TTVR using LuX-valve for valve replacement. The patients were divided into a PPCs group and a non-PPCs group according to the presence of PPCs. The incidence of PPCs after tricuspid valve intervention between the two groups was compared. ResultsOf 19 patients diagnosed with severe or greater tricuspid regurgitation registered in the database, 17 met the inclusion criteria, including 15 females and 2 males, with a mean age of 68.4±8.0 years. PPCs occurred in 9 of 17 (52.9%) patients. At discharge, compared with the non-PPCs group, the PPCs group had a longer postoperative hospital stay [11.0 (10.0, 17.0) d vs. 7.5 (7.0, 8.0) d, P=0.01], longer ICU stay [72.0 (45.5, 95.0) h vs. 20.5 (16.0, 22.8) h, P<0.01], and more hospital cost [74.3 (65.9, 98.3) thousand yuan vs. 52.6 (44.2, 57.4) thousand yuan, P<0.01]. At 30 days of follow-up, the PPCs group was found that the rate of New York Heart Association cardiac function≥class Ⅲ (66.7% vs. 12.5%, P<0.01) was higher, the six-minute walk distance (170.2±169.3 m vs. 377.9±80.5 m, P<0.01) was shorter and Kansas City Cardiomyopathy Questionnaire heart failure score (40.9±31.2 vs. 80.4±5.8, P<0.01) was less than those of the non-PPCs group. ConclusionPPCs are common in the patients undergoing TTVR and severely affect patients' cardiac function, exercise function and quality-of-life recovery. Proactive preoperative intervention as well as early postoperative rehabilitation management should be provided to those at high risk of PPCs.
ObjectiveTo investigate the effect of concomitant tricuspid valve repair during mitral valve surgery on the early and mid-term prognosis of the tricuspid valve and right heart function in the patients with moderate or less tricuspid regurgitation. MethodsA retrospective study of 461 patients with mitral valve disease requiring cardiac surgery combined with moderate or less tricuspid regurgitation in our hospital from 2011 to 2014 was done. They were 309 males and 152 females with a median age of 53.00 (44.00, 60.00) years. According to whether they received tricuspid valve repair (Kay’s annuloplasty, DeVega’s annuloplasty or annular ring implantation), the patients were divided into a mitral valve surgery only group (a nTAP group, n=289) and a concomitant tricuspid valve repair group (a TAP group, n=172). At the same time, 43 patients whose tricuspid valve annulus diameter was less than 40 mm in the TAP group were analyzed in subgroups. ResultsThe median follow-up duration was 3.00 years (range from 0.10 to 9.30 years). There was no perioperative death. Three months after surgery, the anteroposterior diameter of the right ventricle in the TAP group was significantly improved compared with that in the nTAP group [–1.00 (–3.00, 1.00) mm vs. 0.00 (–0.20, 2.00) mm, P=0.048]. Three years after surgery, the improvement of right ventricular anteroposterior diameter in the TAP group was still significant compared with the nTAP group [–1.00 (–2.75, 2.00) mm vs. 2.00 (–0.75, 4.00) mm, P=0.014], and the patients in the TAP group were less likely to develop moderate or more tricuspid regurgitation (3.64% vs. 35.64%, P<0.001). Annuloplasty ring implantation was more effective in preventing regurgitation progression (P=0.044). For patients with a tricuspid annulus diameter less than 40 mm, concomitant tricuspid valve repair was still effective in improving the anteroposterior diameter of the right ventricle in the early follow-up (P=0.036). Conclusion Concomitant tricuspid valve repair for patients with moderate or less tricuspid regurgitation during mitral valve surgery can effectively improve the tricuspid valve and right heart function in the early and mid-term after surgery. Annuloplasty ring implantation is more effective in preventing regurgitation progression. Patients whose tricuspid annulus diameter is less than 40 mm can also benefit from concomitant tricuspid repair.
