Summary
Intraoperative transesophageal echocardiography (TEE) reliably predicts residual mitral regurgitation (MR) compared to postoperative transthoracic echocardiography (TTE), aiding in assessing mitral valve function post-surgery.
Area of Science:
- Cardiovascular Imaging
- Echocardiography
- Cardiac Surgery
Background:
- Intraoperative transesophageal echocardiography (TEE) with color Doppler can measure residual mitral regurgitation (MR).
- The correlation between intraoperative TEE and postoperative transthoracic echocardiography (TTE) for MR measurement is not well-established.
Purpose of the Study:
- To evaluate the correlation between intraoperative TEE and early/late postoperative TTE in measuring residual MR after mitral valve reconstruction.
Main Methods:
- Intraoperative TEE using direct planimetry of the regurgitant jet area was used to measure residual MR in 42 patients.
- Measurements were compared with early and late postoperative TTE findings.
Main Results:
- Intraoperative TEE measurements of residual MR showed significant correlation with both early (r=0.66) and late (r=0.71) postoperative TTE.
- Most patients with no/trivial MR on intraoperative TEE also had no/trivial MR postoperatively.
- Some patients with mild MR on intraoperative TEE developed moderate MR later.
Conclusions:
- Intraoperative TEE is a reliable method for measuring residual MR.
- Intraoperative TEE can accurately predict early and late postoperative mitral valve function and dysfunction.
