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 observe early and intermediate-term clinical outcomes of tricuspid valvuloplasty withannuloplasty ring for the treatment of secondary tricuspid regurgitation （TR） of patients with rheumatic heart disease. MethodsFrom December 2009 to September 2011, 41 patients with rheumatic heart disease underwent left-side heart valve replacementand concomitant tricuspid valvuloplasty with annuloplasty ring in Sichuan Jianyang People’s Hospital. There were 12 males and 29 females with their mean age of 49 （21-67） years. Preoperatively, there were 38 patients with atrial fibrillation, 13 patients with left atrial thrombus; 2 patients with trivial TR, 5 patients with mild TR, 11 patients with moderate TR, and 23 patients with severe TR. Twenty-eight patients received mitral valve replacement and 13 patients received mitral and aortic valve replacement. All the patients were followed up every 3 months at the outpatient department, and received color Doppler echocardiography examination to observe TR degree at the 6th postoperative month. Results Postoperative heart function improved by 2-3 class in all the patients. There were 39 patients with New York Heart Association (NYHA) classⅠorⅡ postoperatively, and postoperative heart function was significantly better than preoperative heart function（P＜0.05）. All the patients were followed up for 6-27 months, and there was no death during follow-up. Color Doppler echocardiography at the 6th postoperative month showed that TR degrees were significantly decreased than preoperative TR degrees. There were 39 patients with trivial or mild TR during follow-up, which was significantly different with preoperativeTR degree （P＜0.05）. Right ventricle dimension decreased from preoperative 20 mm to 17 mm during follow-up, which were statistically different （P＜0.05）. Conclusion Early and intermediate-term clinical outcomes of tricuspid valvuloplasty with annuloplasty ring for the treatment of TR are satisfactory, while further evaluation for its long-term outcome is needed.
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.
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.
