Objective To improve surgical results, the experience of surgical management of Ebstein anomaly in 36 cases is reported and reviewed. Methods Surgical procedures included tricuspid valve replacement (6 cases), Danielson’s operation (28 cases), Carpentier’s operation (2 cases), among them, there were 5 cases of ablation of right atrioventricular accessory pathway. Results Four patients died early after operation in the hospital, 3 from right heart failure (1 case of tricuspid valve replacement and 2 cas...
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.
Objective To evaluate the efficacy of a combination of beating-heart minimally invasive approach and leaflets augmentation technique treating severe tricuspid regurgitation (TR) after cardiac surgery. Methods From January 2015 to August 2017, patients undergoing reoperative tricuspid valve repair (TVP) with minimally invasive approach and leaflets augmentation were enrolled. Cardiopulmonary bypass (CPB) was established via femoral vessels and the procedures were performed on beating heart with normothermic CPB. A bovine pericardial patch was sutured to leaflets to augment the native anterior and posterior leaflets. Other repair techniques, such as ring implantation and leaflet mobilization, were also applied as needed. Results A total of 28 patients (mean age 55.6±10.1 years, 5 males, 23 females) were enrolled. One patient was converted to median sternotomy due to pleural cavity adhesion. Twenty-seven patients underwent totally endoscopic TVP with leaflets augmentation. No patients was transferred to tricuspid valve replacement. Two patients died in hospital. All patients were followed up for 7.4±5.0 months and there was no late death and reoperation. Regurgitation area was converted from 20.7±10.1 cm2 to 3.3±3.3 cm2 after TVP according to the latest echocardiography (P<0.001). Conclusion Minimally TVP with leaflets augmentation is effective in treating severe isolated TR after primary cardiac surgery. It can significantly increase success rate of tricuspid valvuloplasty and decrease the surgical trauma.
Abstract： Objective To evaluate clinical outcomes of tricuspid annuloplasty using a C-type ring made of autologous pericardium for the treatment of functional tricuspid regurgitation （TR）. Methods Eleven patients underwent tricuspid annuloplasty in Guizhou Provincial People’s Hospital between March 2009 and January 2011， including 5 male patients and 6 female patients with their age of 32-57 （43.80±12.20） years. There were 3 patients with mild TR， 7 patients with moderate TR， and 1 patient with severe TR. Concomitant procedures included mitral valve replacement and/or aortic valve replacement and/or left atrial thrombectomy. The C-type ring was created using a strip of pericardium after 0.8% glutaraldehyde fixation for 15 minutes. Interrupted horizontal mattress suture was used to secure the C-type ring to the tricuspid annulus. Hear function and echocardiography were examined during follow-up. Results There was no in-hospital death， and the hospital stay was 15-28 （21.10±3.80） days. All the patients were followed up for 8-28 （18.50±7.00）months. There was no death or reoperation because of TR or tricuspid stenosis during follow-up. Ten patients had TR during follow-up， including 9 patients with mild TR and 1 patient with mild to moderate TR， but there was no patient with severe TR. The degree of TR during follow-up was significantly reduced than preoperative degree （Z =-2.81，P＜0.05）. Preoperative and postoperative right ventricular dimension （19.95±5.11 mm vs. 21.57±12.81 mm，P=0.705） and right atrial dimension（37.55±6.79 mm vs. 35.55±5.22 mm，P=0.317）were not statistically different. Conclusion Tricuspid annuloplasty using a C-type ring made of autologous pericardium has satisfactory clinical outcomes for patients with functional TR.
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.
