Key result
Preoperative real-time three-dimensional transesophageal echocardiography significantly reduced mean cardiopulmonary bypass time (113.0 vs 127.0 min) and aortic cross-clamp time compared to direct intraoperative measurement.

Preoperative real-time 3D TEE to predict artificial chordae length significantly reduces cardiopulmonary bypass and aortic cross-clamp times during mitral valve repair.
Huang et al. (2013) conducted a cohort in Severe mitral regurgitation with mitral valve prolapse (n=48). Preoperative real-time three-dimensional transesophageal echocardiography (RT3D-TEE) vs. Direct intraoperative measurement of normal chordae length was evaluated on Cardiopulmonary bypass time (minutes) (p=<0.05). Preoperative real-time three-dimensional transesophageal echocardiography significantly reduced mean cardiopulmonary bypass time (113.0 vs 127.0 min) and aortic cross-clamp time compared to direct intraoperative measurement.
