Background: This study evaluates the effects of performing real time three-dimensional transesophageal echocardiography in addition to conventional two-dimensional transesophageal echocardiography on diagnostic confidence. Methods: Operator diagnostic confidence in addressing clinical questions posed by the referral was scored using a five-point scale for two-dimensional transesophageal echocardiography alone and the combination of two-dimensional and real time three-dimensional transesophageal echocardiography in 136 consecutive patients undergoing examination in an academic hospital. Results: Mean diagnostic confidence score was higher for the combined studies compared to two-dimensional transesophageal echocardiography alone (4.5 vs. 4.1, P < 0.001)). The addition of real time three-dimensional transesophageal echocardiography increased diagnostic confidence score in 45 (33.1%) patients, and the percentage of studies with total diagnostic confidence rose from 40.4% with two-dimensional transesophageal echocardiography alone to 65.4% after performing real time three-dimensional transesophageal echocardiography. Type of clinical indication was associated with improved score by the combined exams (P < 0.004). The addition of real time three-dimensional transesophageal echocardiography was most likely to improve diagnostic confidence score in studies performed to assess valve disease (56.1%) and least likely in examinations performed for intracardiac infection (14.9%). The location (anterior or posterior) of the primary cardiac pathology was not associated with improved score by the combined studies (P = 0.498). Conclusions: The addition of real time three-dimensional transesophageal echocardiography to two-dimensional transesophageal echocardiography increases diagnostic confidence in examinations routinely performed in an academic practice. Further studies of the impact of real time three-dimensional transesophageal echocardiography on patient management, outcomes and displacement of or need for downstream testing are warranted.
