Key result
Multidetector CT provides essential complementary imaging for TAVR and TMVR preprocedural planning.
Why the study?
Preprocedural planning for TAVR and TMVR requires comprehensive assessment beyond echocardiography, for which multidetector computed tomography provides essential complementary imaging.
MDCT is an essential complementary imaging tool for comprehensive preprocedural planning in patients undergoing TAVR and TMVR.
Supports MDCT in TAVR/TMVR planning; leaves open prospective outcome trials.
Transcatheter aortic valve replacement (TAVR) and transcatheter mitral valve replacement (TMVR) are catheter-based interventional techniques for treating patients having high risk for surgical aortic or mitral valve replacement, respectively. While TAVR is a technique for treating severe aortic stenosis, TMVR is primarily used for treating mitral regurgitation. Echocardiography is the initial imaging modality used for a detailed assessment of the mitral and aortic valve lesions. Multidetector computed tomography (MDCT) is then used as a complementary tool to provide additional information essential for pre-procedure planning. High spatial resolution and good temporal resolution of MDCT along with multiplanar reconstruction technique permit a comprehensive assessment relevant for the multiple aspects of preprocedural planning. The current article outlines the MDCT acquisition protocols, reconstruction techniques, and assessment of various essential parameters for TAVR and TMVR.

Bhatia et al. (2022) conducted a review in Severe aortic stenosis and mitral regurgitation. Multidetector computed tomography (MDCT) was evaluated. Multidetector computed tomography serves as an essential complementary imaging tool for comprehensive preprocedural planning in transcatheter aortic and mitral valve replacement.
