ObjectiveTo investigate the therapeutic effect of modified tricuspid valvuloplasty using anterior leaflet in patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia. MethodsNinety-five patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia underwent surgical treatment in our hospital from June 2002 to March 2014. There were 39 males and 56 females with an average age of 3.2±6.6 years (range 3 months to 46 years). Preoperative echocardiography prompted all patients had varying degrees of tricuspid valve dysplasia and tricuspid regurgitation (mild in 14 cases, moderate in 49 cases, and severe in 32 cases). According to the different development of anterior and septal leaflet, we used different techniques to repair the tricuspid problems. If the residual septal leaflet was larger than one third of the normal septal leaflet, we continuously stitched the half of the septal side of anterior leaflet to the two third of the left side of residual septal leaflet. If the residual septal leaflet was less than one third of the normal septal leaflet, we reserved part of pericardial patch at right side of septal crest at repairing the atrial septal defect, and continuously stitched the left two third of the patch edge to the half of septal side of anterior leaflet. All patients received transesophageal echocardiography (TEE) to evaluate the intraoperative effect of valvuloplasty. The patients were followed up with echocardiography after 3 to 6 months to evaluate the condition of tricuspid. ResultsThere was no perioperative death or Ⅲ degree atrioventricular block. Intraoperative TEE showed that the effect of tricuspid valvuloplasty was good with 3 cases of mild regurgitation and 2 cases of moderate regurgitation. Other 90 cases had no significant regurgitation. The aortic cross-clamping time was 35.2±11.2 min and cardiopulmonary bypass time was 64.9±16.6 min. In the followed-up between 3 to 6 months, tricuspid regurgitation situation improved significantly than that in preoperative period with mild regurgitation or no reflux in 89 cases and moderate regurgitation in 6 cases. There was no severe regurgitation occurred. ConclusionThe therapeutic effect is satisfactory by using anterior leaflet to repair the regurgitation of tricuspid in patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia.
Abstract： Objective To evaluate the surgical effect of ring annuloplasty using prosthetic vascular graft for the treatment of tricuspid regurgitation. Methods From July 2000 to July 2010, ring annuloplasty using prosthetic vascular graft was performed to a total of 56 patients with tricuspid regurgitation in Changhai Hospital of Second Military Medical University. There were 24 male patients and 32 female patients. Their mean age was（45.7±21.8）years (ranging from 14 to 73 years). All the patients were diagnosed as moderate to severe tricuspid regurgitation by color Doppler echocardiography examination, including 47 patients with rheumatic heart valve diseases, and 9 patients with congenital heart disease (Ebstein’s anomaly). All the 56 patients underwent ring annuloplasty using prosthetic vascular graft instead of Carpentier annuloplasty ring for the treatment of tricuspid regurgitation. Results There was no in-hospital death. Postoperatively, one patient had acute respiratory failure, one patient had acute kidney failure, and one patient had re-exploration for bleeding. All patients had none or mild tricuspid regurgitation by echocardiography examination one month after surgery. Forty eight patients were followed up from 1.0 to 9.5 years with a median follow-up time of 3.8 years. During follow-up, there was no late death, but one patient had brain embolism as an anticoagulation complication. Sixteen patients were in New York Heart Association (NYHA) functional classⅠ, 26 patients in NYHA classⅡ, and 6 patients in NYHA class Ⅲ. Thirty six patients had no tricuspid regurgitation, 10 patients had mild tricuspid regurgitation, and 2 patients had moderate tricuspid regurgitation by echocardiography examination during follow-up. Conclusion The early and mid-term follow-up results of ring annuloplasty using prosthetic vascular graft instead of Carpentier annuloplasty ring for the treatment of tricuspid regurgitation are satisfactory. It is a good choice for the surgical treatment of tricuspid regurgitation.
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.
Tricuspid regurgitation (TR) affects a wide population in China, and frequently coexists with other conditions as comorbidities. Moderate to severe TR is associated with a poor prognosis and medical treatment alone does not prevent progression of disease. Although minimal invasive catheter-based techniques might be an option for TR treatment in selected high risk patients, there is no relevant recommendations for the transcatheter treatment of TR in practice guidelines. Several transcatheter edge-to-edge repair devices are currently in preclinical and early clinical evaluation as potential novel treatment options for symptomatic TR in patients at increased risk for surgery, becoming as the most common technique applied for interventional TR treatment. Hence, the present study will introduce the clinical features of TR, the progress of edge-to-edge repair, and the application and challenges in the future.
ObjectiveTo assess the method and the results of tricuspid annuloplasty performed(TVP) with the Edwards MC3 ring. MethodsWe retrospectively analyzed the clinical data of 312 patients with functional tricuspid regurgitation(FTR) secondary to left-sided valve disease in our hospital from June 2012 through May 2014. There were 147 males and 165 females at mean age of 55.7±7.3 years. ResultsThere was no death in the patients because of the planting of MC3 ring. The mean follow-up rate was 99.4%(310/312) for 2 patients immigration abroad. The follow-up time was 0-24(14.2±4.7) months. The ultrasoundcardiogram showed that all the ejection fraction(EF) of right ventricle improved compared with preoperation(P<0.05). The pulmonary artery systolic pressure(SPAP), both internal diameter and regurgitation volume of right ventricle were decreased(P<0.05). In the 310 patients, 302 patients(97.4%) were with the TR class 0-Ⅰ, 5 patients(1.6%) with class Ⅱ, 3 patients(1.0%) with class Ⅲ. There was no severe TR or no patient with reoperation. ConclusionThe MC3 ring is easy for planting and has good repeatability, which provides stable and satisfactory results for plasty of the tricuspid annulus with seldom residue or recurrent TR.
ObjectiveTo summarize clinical outcomes of atrial septal defect (ASD)occlusion for patients with ASD and tricuspid regurgitation (TR). MethodsBetween July 2006 and January 2012, 98 patients with ASD and TR under-went ASD occlusion in Xinhua Hospital, Shanghai Jiaotong University School of Medicine. There were 36 male and 62 female patients with their age aging from 2 months to 80 years. All ASD were secundum ASD with their diameter of 3-23 mm. There were 60 patients with mild TR, 28 patients with moderate TR, and 10 patients with severe TR. All the patients received ASD closure without specific management for TR, including 51 patients under digital subtraction angiography (DSA), 46 patients via a minithoracotomy approach, and 1 patient guided by transthoracic echocardiography. All the patients were followed up with echocardiography to evaluate changes of TR after ASD closure. ResultsThere was no in-hospital death. ASD occlusion was not successful in 1 patient who was found to have residual ASD shunt on the third postoperative day. Another patient underwent reexploration for abnormal bleeding on the third postoperative day. All the other patients had uneventful postoperative recovery. Eighty-four patients were followed up for 1-64 (26.56±21.35)months. During follow-up, the patient who have residual ASD shunt on the third postoperative day received open chest repair 6 months after discharge. TR of 73 patients (86.90%)improved in different degrees. Preoperative severe TR in 10 patients changed into mild TR in 8 patients, moderate TR in 1 patients and still severe TR in 1 patient. Preoperative moderate TR in 26 patients changed into none TR in 6 patients, mild TR in 18 patients and still moderate TR in 2 patients. Preoperative mild TR in 48 patients changed into none TR in 40 patients and still mild TR in 8 patients. ConclusionFor patients with ASD and TR, conservative treatment strategy is recommended. Simple ASD closure can provide satisfactory clinical outcomes, and also avoid adverse complications of cardiopulmonary bypass including myocardial injury and lung injury.
One of its primary surgical treatments of tricuspid regurgitation is tricuspid valve biological valve replacement. Catheter tricuspid valve-in-valve implantation is a novel interventional alternative for biological valve failure. The non-invasive lung fluid measuring device remote dielectric sensing (ReDSTM) has been increasingly incorporated into clinical practice as a means of monitoring chronic heart failure in recent years. This report describes the process and outcomes of the first instance of perioperative lung fluid volume evaluation following transcatheter tricuspid valve implantation utilizing ReDSTM technology. The patient has a short-term, substantial increase in postoperative lung fluid volume as compared to baseline.
Objective To analyze and explore the risk factors of secondary tricuspid regurgitation (TR) after left-sided valve surgery (left cardiac valve replacement or valvuloplasty) using meta-analysis, so as to provide evidence for clinical diagnosis and treatment of secondary TR. Methods We electronically searched databases including PubMed, MEDLINE, CBM, CNKI, VIP, for literature on the risk factors of secondary TR after left-sided valve surgery from 1995 to 2012. According to the inclusion and exclusion criteria, we screened literature, extracted data, and assessed methodological quality. Then, meta-analysis was performed using RevMan 5.0 software. Results A total of 6 case-control studies were included, involving 437 patients and 2 102 controls. The results of meta-analysis showed that, the risk factors of progressive exacerbation of secondary TR after left-sided valve surgery included preoperative atrial fibrillation (OR=3.90, 95%CI 3.00 to 5.07; adjusted OR=3.04, 95%CI 2.21 to 4.16), age (MD=5.36, 95%CI 3.49 to 7.23), huge left atrium (OR=5.17, 95%CI 3.12 to 8.57; adjusted OR=1.91, 95%CI 1.49 to 2.44) or left atrium diameter (MD=4.85, 95%CI 3.18 to 6.53), degradation of left heart function (OR=2.97, 95%CI 1.73 to 5.08), rheumatic pathological change (OR=3.06, 95%CI 1.66 to 4.68), preoperative TR no less than 2+ (OR=3.52, 95%CI 1.26 to 9.89), and mitral valve replacement (MVR) (OR=2.35, 95%CI 1.68 to 3.30). Sex (OR=1.54, 95%CI 0.94 to 2.52) and preoperative pulmonary arterial hypertension (OR=1.28, 95%CI 0.77 to 2.12) were not associated with secondary TR after left-sided valve surgery. Conclusion The risk factors of progressive exacerbation of secondary TR after left-sided valve surgery include preoperative atrial fibrillation, age, huge left atrium or left atrium diameter, degradation of left heart function, rheumatic pathological change, preoperative TR no less than 2+, and MVR. Understanding these risk factors helps us to improve the long-time effectiveness of preventing and treating TR after left-sided valve surgery.
In historic perspectives, tricuspid valve was considered as “forgotten valve” in the cardiovascular field. Tricuspid regurgitation (TR) is the main disease of the tricuspid valve, and the number of patients is large. TR patients have mostly treated conservatively with drugs due to high surgical mortality, so the effective treatment of TR patients is far from satisfactory. With the development of interventional technology, transcatheter tricuspid valve intervention (TTVI) is expected to become a better choice. In recent years, a number of TTVI devices have entered clinical trials and achieved good results. Due to the late development of TTVI technology and insufficient accumulation of clinical applications, there are no uniform inclusion criteria and evaluation indicators for research endpoints when conducting clinical trials. This article focuses on the introduction of different instruments of TTVI, and summarizes the current status, research progress and problems of these treatments.
Objective To observe whether the adoptation of tricuspid annulus diameter as surgical indication for tricuspid annuloplasty will reduce the occurrence of moderate-severe tricuspid regurgitation(TR) in patients after mitral valve replacement (MVR). Methods Between April 2005 and June 2006, MVR was performed in 56 patients with no or mild TR in our Department. The patients were divided into two groups according to tricuspid annulus diameter(TAD)/body surface area (BSA)≥21mm/m2. Tricuspid annuloplasty group(TA group): 22 cases, male 8, female 14, age 45.0±7.7 years, TAD 36.8±3.8mm, BSA 1.57±0.15m2, New York Heart Association(NYHA) functional class Ⅲ/Ⅲ-Ⅳ 18/4, sinus rhythm(SR)/atrial fibrillation (AF) 2/20. Notricuspid annuloplasty group (NTA group): 34 cases, male 9, female 25, age 42.9±11.0 years, TAD 28.5±4.4mm, BSA 1.58±0.13m2, NYHA Ⅲ/Ⅲ-Ⅳ 28/6, SR/AF 9/25. Kay annuloplasty was performed for TA group patients. The patients were followed in outpatient clinical regularly and evaluated by echocardiography at 6 months after operation. Results All patients recovered and were discharged from hospital. The duration of follow-up was 11.0±2.4 months. Except 2 cases, all patients received echocardiography evaluation at 6 months after operation. There were no significantly differences between two groups patients in general clinical characteristics (Pgt;0.05). Compared with NTA group before operation, right atrial diameter (RAD, 49.3±7.0mm) and TAD(36.8±3.8mm) were bigger and more mild TR in TA group (Plt;0.05). RAD(44.1±8.9mm) and TAD(28.9±6.1mm) reduced and the proportion of TR degree improved (Plt;0.05) in TA group but did not occur in NTA group after surgery (Pgt;0.05). There were three cases of moderate TR in NTA group. Conclusion Tricuspid annuloplasty adopting TAD as surgical indication may reduce the occurrences of postoperative moderate-severe TR for patients of MVR with no or mild preoperative TR.
