Key result
Intraoperative transoesophageal echocardiography detected significant residual mitral regurgitation in 8.2% of patients, all of whom had been assessed as successful by saline testing.
Why the study?
Does intraoperative transoesophageal echocardiography improve the detection of residual mitral regurgitation compared to surgeon's assessment in patients undergoing mitral valve repair?
Observational (n=86)

Intraoperative TOE is highly sensitive for detecting residual mitral regurgitation missed by standard surgical assessment, allowing for immediate correction during mitral valve repair.
No takes yet. Share an insight, caveat, or question.
May detect residual MR missed by saline testing; hypothesis-generating for routine TOE use in mitral repair pending trials.
Kalman et al. (1993) conducted an observational in Mitral regurgitation (n=86). Intraoperative transoesophageal echocardiography (TOE) vs. Surgeon's assessment (saline insufflation and pulmonary capillary wedge pressure) was evaluated on Detection of significant residual regurgitation (≥ 3+). Intraoperative transoesophageal echocardiography detected significant residual mitral regurgitation in 8.2% of patients, all of whom had been assessed as successful by saline testing.
