Key result
Transthoracic echocardiography showed 87.5% agreement with transesophageal echocardiography for classifying patients as suitable for transcatheter edge-to-edge mitral valve repair.
Why the study?
While TTE is the initial diagnostic tool in patients evaluated for M-TEER, TOE provides superior anatomical details, leaving it uncertain whether TTE is as effective as TOE for selecting eligible patients.
Does transthoracic echocardiography (TTE) provide comparable assessment to transesophageal echocardiography (TOE) for selecting patients with severe mitral regurgitation eligible for M-TEER?
Population
40 patients with severe MR eligible for TEER
Comparison
TTE assessment vs TOE assessment

Does transthoracic echocardiography (TTE) provide comparable assessment to transesophageal echocardiography (TOE) for selecting patients with severe mitral regurgitation eligible for M-TEER?
TTE demonstrates strong correlation and high agreement with TOE for assessing mitral valve anatomy and determining M-TEER eligibility, suggesting it could serve as a viable alternative for pre-procedural screening.
Bonanni et al. (2025) conducted an observational in Severe mitral regurgitation (n=40). Transthoracic echocardiography (TTE) vs. Transesophageal echocardiography (TOE) was evaluated on Agreement for classifying patients as suitable for M-TEER. Transthoracic echocardiography showed 87.5% agreement with transesophageal echocardiography for classifying patients as suitable for transcatheter edge-to-edge mitral valve repair.
