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 compare the efficacy of additional tricuspid valve annuloplasty (TVP) and isolated closure for atrial septal defect (ASD) with moderate to severe tricuspid regurgitation (TR). MethodsClinical data of the patients diagnosed with ASD combined with secondary moderate to severe TR and treated in our hospital from January 2009 to June 2020 were retrospectively analyzed. Patients were divided into a TVP group and a non-TVP group based on whether TVP was performed simultaneously. The baseline data of two groups were matched with a ratio of 1∶1 propensity score. ResultsA total of 32 pairs from 257 patients were successfully matched. In the TVP group, there were 24 females and 8 males with an average age of 44.0±13.1 years. In the non-TVP group, there were 28 females and 4 males with an average age of 44.5±11.6 years. The TR area and estimated pulmonary artery pressure in the two groups were significantly decreased compared with preoperation (all P<0.001). The TR area (P=0.001) and the estimated pulmonary artery pressure (P=0.002) were decreased more significantly in the TVP group than those in the non-TVP group. Linear regression analysis showed that age and preoperative TR area had a positive correlation with TR area at follow-up (β=0.045 and 0.259, respectively, both P<0.05), while additional TVP had a negative correlation (β=–1.542, P=0.001). ConclusionAdditional TVP can significantly reduce the TR area and pulmonary artery pressure, and elderly patients with severe TR before surgery should actively receive TVP.
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.
Objective To evaluate long-term clinical results in patients who underwent mitral valve replacement and suture tricuspid annuloplasty. Methods We included 401 patients who underwent mitral valve replacement and suture tricuspid annuloplasty in our hospital between January 2006 and March 2011. There were 309 females and 92 males at age of 17-71 (46.2±12.0) years. All patients were investigated by echocardiography at postoperative 5 years. The tricuspid valve procedures consisted of bicuspidization, modified Kay annuloplasty and leaflet repair according to the actual conditions. Results The patients were followed up for 5–10 (7.4±1.4) years. As compared with preoperation, the right atrium (RA, 7.6±13.0 mm vs. 49.3±13.2 mm), right ventrium (RV, 23.2±4.7 mm vs. 22.0±3.6 mm), left atrium (LA, 59.7±19.0 mm vs. 53.6±14.7 mm, left ventrium (LV, 49.3±8.6 mm vs. 47.7±6.2 mm), tricuspid of end-distolic diameters (TEDD, 35.9±5.7 mm vs. 32.8±5.9 mm) and tricuspid of end-systolic diameters (TESD, 9.4±5.7 mm vs. 26.5±4.9 mm) of patients decreased significantly at postoperation (P<0.01). As compared with preoperation, left ventricular ejection fraction (LVEF, 60.3%±8.9% vs. 61.7%±8.3%) and left ventricular fractional shortening (LVFS, 32.6%±6.3% vs. 33.8%±5.5%) raised significantly at postoperation (P<0.01). As compared with preoperation, the constituent rate of tricuspid regurgitation (TR) improved significantly at postoperation (P<0.01). Conclusion Tricuspid annuloplasty adopting TEDD as a surgical indication is reasonable for patients with mitral diseases. Combined and individualized suture tricuspid annuloplasty can obtain better long-term results. It is needed to order aggressive diuretics treatment for patients with postoperative TR.
ObjectiveTo investigate the predictive value of right atrial myocardial fibrosis in the prognosis of isolated tricuspid regurgitation surgery after left heart valve surgery. MethodsThe patients who underwent tricuspid valvuloplasty by the same operator in Guangdong Provincial People's Hospital from April 2016 to August 2021 due to long-term isolated severe tricuspid regurgitation after left heart valve surgery were included in the study. According to the degree of right atrial myocardial fibrosis, the patients were divided into three groups: a mild group, a moderate group, and a severe group. The clinical data of these patients were compared and analyzed. ResultsA total of 75 patients were enrolled, including 16 males and 59 females with an average age of 57.0±8.4 years. There were 30 patients in the mild group, 29 patients in the moderate group and 16 patients in the severe group. In terms of the preoperative data, there were statistical differences in cardiac function grade, right atrial diameter, tricuspid incompetence area among the three groups (P<0.05). In terms of the postoperative data, there were statistical differences among the three groups in the cardiopulmonary bypass time, mechanical ventilation time, ICU monitoring time, complication rate and mortality (P<0.05). Further pairwise comparison showed that, compared with the mild group, the severe group had longer mechanical ventilation time (P=0.024), longer ICU monitoring time (P=0.003) and higher incidence of postoperative complications (P=0.024), while the moderate group had no statistical difference in all aspects (P>0.05); compared with the moderate group, the severe group had longer ICU monitoring time (P=0.021) and higher incidence of complications (P=0.006). ConclusionThe early outcome of tricuspid valvuloplasty in patients with isolated tricuspid regurgitation after left heart valve surgery with severe right atrial myocardial fibrosis is worse than that in the patients with mild and moderate fibrosis, suggesting that the degree of myocardial fibrosis in the right atrium can be a predictor of the effect of tricuspid regurgitation surgery and a judgement indicator of the surgery timing.
Functional tricuspid valve regurgitation (TR) is often secondary to left-sided valvular heart diseases. The precise diagnosis of TR degree and reasonable treatment can improve the long-term prognosis of patient. Now we believe that rectifying the TR during left cardiac valve surgery can prevent a further development of TR and avoid the reducing of the cardiac function for patients with moderate TR, tricuspid valve annulus diameter>40 mm in late diastole, tricuspid valve diameter/body surface area>21 mm/m2, and intraoperative tricuspid valve diameter >70 mm, especially for patients with atrial fibrillation and atrial enlargement. The use of prosthetic ring can effectively prevent recurrence of TR in long term and we should try to use hard or semihard "C" shape prosthetic ring as much as possible. The tricuspid valve replacement should be avioded because of its higher mortality.
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.
