Abstract:
Objective To assess and compare the the results of tricuspid annuloplasty performed with the Edwards MC3 and Kay methode.Methods From January 2010 to May 2014, 759 patients with function tricuspid regurgitation(FTR) secondary to left-sided valve disease received tricuspid annuloplasty.Cardiac ultrasound Heartbeat diagram were made to confirm the degree of tricuspid regurgitation, the diameter of tricuspid annulus, the pressure of pulmonary artery and the heart function both in the left and the right, and so on.Of them, 355 cases of male, female 404 cases, at the mean age of(54.1 ± 8.3) years old, with the heart function classical(NYHA) : Ⅰ 13, Ⅱ 177, Ⅲ 400, Ⅳ 169, the mean left ventricles ejection fraction(LVEF) was 0.53 ±0.04, the mean pulmonary artery pressure was(62.5 ± 17.6) mmHg(1 mmHg =0.133 kPa).The diagnosis include rheumatic heart disease 517 cases, degenerative disease 209 cases and infective endocarditis 33 cases.The operation include mitral annuloplasty 132 case, mitral replacement 295 cases, mitral annuloplasty and aortic replacement 20 cases, mitral and aortic replacement 388 cases, CABG 86 cases and Maze Ⅲ methode 23 cases.The degree of tricuspid regurgitation before the operation were class Ⅰ 88, Ⅱ 189, Ⅲ 352 and V 130.From January 2010 to May 2012, 447 cases received Kay' s methods and 312 cases received MC3 annuloplasty ring during May 2012 to May 2014.In the MC3, We use the rings in 28mm size were 79 cases, 30 mm 155 cases, 32 mm 66 cases and 34 mm 12 cases.Results There were no death, reoperation and adverse events in both groups.There were no diffent in the aorta block time, the circulation bypass time, the time of mechanical ventilation, stay in ICU and in the hospital(P ＞ 0.05).All the patient were followed up regularity.The rat of follow up was 90.4％ (686/759), and the mean time of follow up was(39.9 ± 7.7) month.The patients' s EF increased, inner diameter of the right ventricle decreased in both group.There were no severe TR in the patients in the Kay group within 3 months, and 1 case of severe TR 1 year later, as 5 cases at 2 years and 12 cases after 2 years.The regurgitation volume of tricuspid was (3.4 ± 1.4) ml at the moment of 3 month, (6.5 ± 2.1) ml at 1 year, (7.9 ± 2.5) ml at 2 years and (12.4 ± 4.7)ml 2 years later.In the MC3 group, there were no severe TR in the patients during all the stage of fellow-up.There were on regurgitation in the patient within 3 months, 1 case of Class Ⅲ of TR at 1 year and 3 cases of Class Ⅲ at 2 years, without worse TR happen.At the same stage as in MC3 group, the regurgitation volume was(2.9 ±0.9) ml,(3.5 ±1.3) ml and(3.4 ±2.1) ml.The result in MC3 group was similar with Kay group(P ＞0.05) in short term, but much better in the long-term(P ＜ 0.05).Conclusion The Kay methode has good early result, but not the same good in the long-term, which can be applied in the elder persons or the patient without long Life expectancy.And the MC3 ring can correct the FTR enduringly and effectually, specifically the size in small one which behaves perfectly.The MC3 ring should be used in the young patient or the patient wants more.
