Key result
Cardiac computed tomography angiography (CCTA) parameters correlated well with transesophageal echocardiography (TEE) for evaluating the mitral valve apparatus before percutaneous edge-to-edge repair.
Why the study?
TEE is the mainstay for evaluating severe mitral regurgitation before percutaneous edge-to-edge repair but has limitations, whereas CCTA enables multiplanar measurements with high spatial resolution and good calcium visibility.
Does cardiac computed tomography angiography (CCTA) correlate with transesophageal echocardiography (TEE) for evaluating the mitral valve apparatus in patients with severe secondary mitral regurgitation before percutaneous edge-to-edge repair?

Does cardiac computed tomography angiography (CCTA) correlate with transesophageal echocardiography (TEE) for evaluating the mitral valve apparatus in patients with severe secondary mitral regurgitation before percutaneous edge-to-edge repair?
CCTA is a feasible alternative or adjunct to TEE for evaluating the mitral valve apparatus prior to percutaneous edge-to-edge repair, offering good correlation for anatomical measurements and improved calcium visibility.
No takes yet. Share an insight, caveat, or question.
CCTA may support TEE as adjunct for mitral assessment pre-repair; leaves open prospective validation before practice change.
Renker et al. (2021) conducted an observational in Severe mitral regurgitation (n=30). Cardiac computed tomography angiography (CCTA) vs. Transesophageal echocardiography (TEE) was evaluated on Correlation of quantitative parameters relevant for percutaneous edge-to-edge mitral valve repair between CCTA and TEE. Cardiac computed tomography angiography (CCTA) parameters correlated well with transesophageal echocardiography (TEE) for evaluating the mitral valve apparatus before percutaneous edge-to-edge repair.
