PG - 478-485 LID - 10.1055/s-0038-1673665 [doi] AB - BACKGROUND: Functional tricuspid regurgitation (FTR) secondary to left-sided heart disease may lead to poor quality of life and reduced long-term survival. This study evaluated clinical and functional outcomes of patients undergoing tricuspid valve (TV) repair using a rigid three-dimensional ring (Contour 3D, Medtronic) concomitant with another procedure. METHODS: From September 2011 to July 2015, 112 patients (mean age 70.9 +/- 9.0 years) were enrolled at 10 centers in Europe, Israel, and the United States. Inclusion criteria were FTR >/= moderate and/or tricuspid annular diameter (TAD) >/= 40 mm. Echocardiography was planned before surgery and at discharge with echocardiographic and clinical follow-ups performed 6 months postoperatively. RESULTS: Three fourths (74.4%) of patients had higher than moderate TR. Mean TAD was 41.0 +/- 7.3 mm; 61.7% of patients were in the New York Heart Association (NYHA) class III/IV. The most common concomitant procedure was mitral valve repair (57 patients, 53.3%). The 30-day mortality rate was 0.9% (n = 1). The mean EuroSCORE II was 8.9 +/- 8.4% (median: 5.9%; interquartile range: 3.5-11.5%). The observed to expected ratio (O/E) based on the median was 0.1. Six deaths occurred during follow-up (three cardiac related). Mean implanted ring size was 30.3 +/- 2.7. At 6 months, 94.4% of patients showed
