Lesion-Specific Peri-Coronary Fat Attenuation Index Is Associated With Functional Myocardial Ischemia Defined by Abnormal Fractional Flow Reserve

Frontiers in Cardiovascular Medicine, 2021
Background: The association between abnormal invasive fractional flow reserve (FFR) and the fat attenuation index (FAI) of lesion-specific peri-coronary adipose tissue (PCAT) is unclear. Method: Data of patients who underwent coronary computed tomography

Bridging the Gap in a Rare Cause of Angina

European Cardiology Review, 2021
Myocardial bridging occurs when coronary arteries run intramurally. Episodes of tachycardia can cause a dynamic obstruction that extends into diastole, compromising coronary filling time, and subsequently leading to ischaemia. Myocardial ischaemia, acute

CT Assessment of Myocardial Perfusion and Fractional Flow Reserve in Coronary Artery Disease: A Review of Current Clinical Evidence and Recent Developments

Korean Journal of Radiology, 2021
Coronary computed tomography angiography (CCTA) is routinely used for anatomical assessment of coronary artery disease (CAD). However, invasive measurement of fractional flow reserve (FFR) is the current gold standard for the diagnosis of hemodynamically

Encasement of the left anterior descending coronary artery: association with Takotsubo syndrome, and diagnostic and therapeutic options

Global Cardiology, 2023
Myocardial bridging is a rare event, which leads to chest pain, arrhythmias and discussable Takotsubo syndrome (cardiomyopathy). We enrolled 41 patients (33 females, mean age 68.4 years), the majority of whom had Takotsubo cardiomyopathy in any form ...

Prognostic value of CT-derived myocardial blood flow, CT fractional flow reserve and high-risk plaque features for predicting major adverse cardiac events.

Cardiovascular Diagnosis and Therapy, 2021
Background Myocardial blood flow (MBF), CT fractional flow reserve (CT-FFR) and high-risk plaque (HRP) features have been revealed to be associated with patients' prognosis.
