Abstract
BACKGROUND: To compare results of tricuspid valve (TV) reoperation between incision via a right anterolateral minithoracotomy (RAMT) and median sternotomy (MS). METHODS: We performed a retrospective analysis of 49 patients who underwent isolated TV surgery as a reoperation at our institution between 2006 and 2015. Previous cardiac operations included mitral, aortic, and TV surgeries, atrial septal defect repair, and pericardiectomy. The mean age of the patients was 51.9±12.8 years, 14 (28%) were male and 35 (72%) were female. Follow-up was 95% (38/40) complete, with a mean duration of 41.3±19.5 months. RESULTS: Perioperative demographic and laboratory tests did not show any significant differences between the RAMT and MS groups. The drainage volume, total red cell unit, total serum volume and platelet were significantly different 1150±803.5/2,270±1,920, 4.8±4.1/8.7±8.9, 478.2±488.9/950.0±857.6, 0.04±0.21/0.38±0.64 (P<0.05), while other perioperative data were similar. There were no significant differences in early postoperative death and complications between the RAMT and MS groups. A multivariate linear regression analysis predicted that serum creatinine (Scr), age, and MS group were independent risk factors for bleeding. The Cox regression demonstrated that the MS group had a longer drainage duration (P<0.05) and had a relative hazardous risk (HR) of 2.691 (1.328, 5.450 CI) compared with the RAMT group. CONCLUSIONS: The RAMT approach is an alternative, safe, and feasible procedure for isolated TV reoperation. It has the advantages of less drainage and reduced requirement for blood products.
