Zusammenfassung:Abstract OBJECTIVES The morphology of the tricuspid valve (TV), particularly valves with two posterior leaflets, is attracting attention. The present study was performed to investigate the usefulness of three-dimensional transoesophageal echocardiographic data for morphological evaluation of the TV . METHODS Sixty patients underwent morphological evaluation of the TV by preoperative transoesophageal echocardiography followed by TV repair with median sternotomy, and each leaflet was measured intraoperatively. We analysed the TV morphology in 51 patients whose preoperative echocardiographic findings were consistent with intraoperative findings. RESULTS The mid-systolic echo data, which included the annulus diameter of each leaflet, were correlated with the intraoperative evaluation findings compared with those in the mid-diastole. The annulus and area of the posterior leaflet were larger in patients with two than one posterior leaflet valve (42.4 ± 13.5 vs 30.7 ± 9.1 mm, P
