  • Modified De Vega Annuloplasty Is Superior to Traditional De Vega Technique

    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.
