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.
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.
Objective To compare the efficacy of one kind of modified De Vega technique and traditional De Vega technique. Methods From January 2002 to August 2005, 70 patients were treated with tricuspid valve plasty. These patients were divided into modified De Vega annuloplasty group and traditional De Vega annuloplasty group randomly before operation. The tricuspid regurgitation （TR） were functional and secondary in all patients. The grade of TR and New York Heart Association（NYHA） functional class of two groups were analyzed by Ridit analysis. The changes of right ventricular end-diastolic dimension of two groups were analyzed by paired-sample t test. Results There was no statistically difference between two groups about preoperative characteristics. The follow-up time of modified De Vega annuloplasty group was 12.91±8.84 months and that of traditional De Vega annuloplasty group was 13.61±11.21 months. There was no significant difference between two groups. The outcome of follow-up was satisfactory. In modified De Vega annuloplasty group, there were 12 patient with no TR, 17 patient with mild TR, and 6 patients with moderate TR. There was no patient with severe TR. In traditional De Vega annuloplasty group, 7 patients were observed with no TR, 19 patients mild TR, 7 patients moderate TR and 2 patients severe TR. In modified De Vega annuloplasty group, 32 patients were in NYHA class Ⅰ, 2 patients in NYHA class Ⅱ and only 1 patient in NYHA class Ⅲ. As for traditional De Vega annuloplasty group, 31 patients were in NYHA class Ⅰ, 2 patients in NYHA class Ⅱ and 2 patients in NYHA class Ⅲ. The Ridit analysis showed that there was no significant difference about NYHA class between two groups. However, the difference of TR between two groups was statistically significant （P〈0.05）. The outcome of modified De Vega annuloplasty was superior to that of traditional De Vega technique. Paired-sample t test demonstrated that the modified De Vega annuloplasty could reduce the right ventricular end-diastolic dimension significantly （P〈0.05）. However, the right ventricular end-diastolic dimension of traditional De Vega annuloplasty groups did not change significantly （P 〉 0.05）. Conclusion The efficacy of modified tricuspid De Vega technique is superior to that of traditional De Vega technique in patients with secondary TR.
