Reproducibility in Echocardiographic Two‐ and Three‐Dimensional Mitral Valve Assessment

Three‐dimensional transesophageal echocardiography (3DTEE) has been demonstrated to provide more accurate information than two‐dimensional transesophageal echocardiography (2DTEE) in the localization of mitral valve prolapse (MVP). However, most studies have been single‐rater studies. Few results were tested for inter‐observer variability with a single second rater. This multicenter study aimed to determine reliability of 2D and 3DTEE mitral valve evaluations by calculating inter‐observer agreement between various echocardiographers.
