Key result
Cardiac CT shows promise as an all-in-one modality to optimize CRT selection and lead placement.
Why the study?
Between 30-40% of CRT patients do not improve in LV function, and current multimodality imaging approaches might be streamlined by cardiac CT as an all-in-one acquisition method.
Does cardiac CT as a singular imaging modality improve patient selection and guided placement for CRT?

Cardiac CT offers a potential all-in-one imaging modality to optimize patient selection and lead placement in CRT, potentially improving response rates.
Between 30-40% of patients with cardiac resynchronization therapy (CRT) do not show an improvement in left ventricular (LV) function. It is generally known that patient selection, LV lead implantation location, and device timing optimization are the three main factors that determine CRT response. Research has shown that image-guided CRT placement, which takes into account both anatomical and functional cardiac properties, positively affects the CRT response rate. In current clinical practice, a multimodality imaging approach comprised of echocardiography, cardiac magnetic resonance imaging, or nuclear medicine imaging is used to capture these features. However, with cardiac computed tomography (CT), one has an all-in-one acquisition method for both patient selection and the division of a patient-tailored, image-guided CRT placement strategy. This review discusses the applicability of CT in CRT patient identification, selection, and guided placement, offering insights into potential advancements in optimizing CRT outcomes.

Gerrits et al. (2023) conducted a review in Heart failure requiring cardiac resynchronization therapy (CRT). Cardiac Computed Tomography (CT) vs. Standard imaging modalities (Echocardiography, CMR) was evaluated. Cardiac computed tomography shows promise as a versatile, all-in-one imaging modality for identifying candidates for cardiac resynchronization therapy and guiding patient-tailored lead placement.
