Comparison of Intraoperative Three-Dimensional Doppler Color Flow Mapping to Assess Mitral Regurgitation
Hien MD et al. – Intraoperative Three–dimensional (3D) methods to determine mitral regurgitation (MR) were feasible and showed improved correlation with vena contracta area (VCA) compared to 2D measurements. The agreement of 2D methods with VCA declined from functional MR to MR due to prolapse. The authors recommend the utilization of 3D color Doppler for intraoperative evaluation of MR, especially in patients with complex mitral valve prolapses.
