BACKGROUND: Tricuspid valve (TV) regurgitation has recently been identified as a major risk factor for long-term mortality. Isolated reoperative tricuspid valve repair/replacement (TVR/r) carries an excessively high operative risk. Currently, isolated TVR/r with minimally invasive access through a right lateral thoracotomy is being used increasingly in our institution to treat progressive TV pathologic processes after previous cardiac operations. We analyzed our early and midterm results with reoperative TVR/r in this unique patient cohort.
METHODS: Forty-eight consecutive patients underwent isolated TV operations after previous cardiac operations with minimally invasive access through a right lateral thoracotomy at our institution between September 2000 and December 2011. Previous cardiac operations included 26 patients (54.2%) with mitral valve replacement/repair, 18 patients (37.5%) with an aortic valve replacement, 10 patients (20.4%) with a TVR/r, and 8 patients (16.7%) with coronary artery bypass grafting. Operations were performed electively in 79% of patients (n=38). Mean patient age was 63.8±13.4 years, with an average log EuroSCORE of 13.9%±11.3%; 67% of patients were women. Follow-up was 94% complete, with a mean duration of 2.8±2.3 years.
RESULTS: Thirty-day mortality for patients undergoing elective surgery was zero. For all patients early mortality was 4.2%. Five-year survival for patients after elective reoperative TVR/r through minimally invasive access was 72.2%±10.0%, and 5-year freedom from TV-related reoperations was 88.1%±6.7%, respectively.
CONCLUSIONS: Minimally invasive access through a right thoracotomy provides a safe option for reoperative TVR and offers excellent early outcome, particularly in elective cases. Surgical intervention should be performed earlier rather than later.
