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.
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.
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.
