Objective: Epicardial fat is associated with cardiovascular risk factors and adverse outcomes. However, it is not clear if epicardial fat remains to be a mortality risk when coronary calcium score (CAC) is taken into account.

Methods: We studied the 1005 participants from the St.

Article Synopsis
  • Coronary CT angiography (CCTA) is effective in identifying coronary plaques, particularly those with high-risk features, and has been validated against optical coherence tomography (OCT).
  • In a study of 188 plaques and 84 normal sections, CCTA demonstrated high sensitivity (92%) and specificity (98%) for detecting plaques identified by OCT.
  • The primary limitation of CCTA was its inability to detect very small plaques (sub-millimeter), which could represent early atherosclerosis, with misclassification issues contributing to false negatives in mixed plaques.

Background: We investigated computed tomography (CT) angiography (CTA) in assessment of left atrial appendage (LAA) stasis and thrombus in preprocedural evaluation for atrial fibrillation (AF) ablation in a large community cohort.

Methods And Results: We reviewed CTA and transesophageal echocardiographic images obtained in 861 consecutive patients with a history of AF undergoing same-day CTA and transesophageal echocardiogram (TEE) before AF ablation at a single hospital (2006-2013). CTA findings of LAA filling defects from acquisitions without electrocardiogram gating were compared to TEE features of LAA stasis (grade 0-4) and thrombus.
