Fig. 1From: Transesophageal echocardiography in robot-assisted mitral valve repair for Barlow’s disease: usefulness for predicting artificial ring size and artificial chordae length using the loop techniqueSizing of the mitral valve when treating Barlow’s disease was performed using three-dimensional TEE at the end of systole. The optimal ring size was determined mainly with reference to the intercommissural (IC) distance. When changing the predetermined ring size, the height of the A2 segment of the anterior leaflet (A-height) was considered. In cases with a short A-height and long IC, size was determined by considering the intertrigonal (IT) distance, longitudinal diameter (LD), and transverse diameter (TD).
