Key result
Preoperative MDCT identifies leaflet pathology in 77% of patients, matching 3D TEE for TMVr planning.
Why the study?
Transesophageal echocardiogram is the gold standard for TMVr planning but is invasive, and the utility of MDCT as a noninvasive alternative was unclear.
Does MDCT provide similar anatomical measurements to 3D TEE for preoperative planning of transcatheter mitral valve repair in patients with degenerative mitral regurgitation?
Population
22 patients undergoing TMVr or evaluated for transcatheter mitral valve replacement with degenerative MR and preoperative MDCT
Comparison
Preoperative MDCT vs preoperative 3D TEE
Design
Retrospective single-center observational study with blinded readers

Does MDCT provide similar anatomical measurements to 3D TEE for preoperative planning of transcatheter mitral valve repair in patients with degenerative mitral regurgitation?
MDCT provides comparable anatomical measurements to 3D TEE for preoperative TMVr planning, suggesting it could serve as a non-invasive alternative.
Basman et al. (2022) conducted an observational in Degenerative mitral regurgitation (n=22). Multi-detector computed tomographic angiography (MDCT) vs. 3D Transesophageal echocardiogram (TEE) was evaluated on Correct identification of leaflet pathology. Preoperative MDCT correctly identified leaflet pathology in 77% and dysfunctional leaflet location in 95% of patients, yielding similar measurements to 3D TEE for TMVr planning.
