Pericoronary adipose tissue CT attenuation and its association with serum levels of atherosclerosis-relevant inflammatory mediators, coronary calcification and major adverse cardiac events
Increased attenuation of pericoronary adipose tissue (PCAT) around the right coronary artery (RCA) derived from coronary CTA might detect coronary inflammation. We investigated a potential association between RCA PCAT attenuation and serum levels of atherosclerosis-relevant cytokines and MACE (coronary revascularization, myocardial infarction and/or cardiac death).Coronary atherosclerosis scoring with semiquantitative CCTA risk scores for prediction of major adverse cardiac events: Propensity score-based analysis of diabetic and non-diabetic patients
We aimed to compare semiquantitative coronary computed tomography angiography (CCTA) risk scores – which score presence, extent, composition, stenosis and/or location of coronary artery disease (CAD) – and their prognostic value between patients with and without diabetes mellitus (DM). Risk scores derived from general chest-pain populations are often challenging to apply in DM patients, because of numerous confounders.A cross-sectional survey of coronary plaque composition in individuals on non-statin lipid lowering drug therapies and undergoing coronary computed tomography angiography
Non-statin therapy (NST) is used as second-line treatment when statin monotherapy is inadequate or poorly tolerated.Ventricular septal rupture and right ventricular intramyocardial dissection secondary to acute inferior myocardial infarction
A 61-year-old female patient presented with sub acute myocardial infarction with an occluded right coronary artery on invasive evaluation and a ventricular septal rupture on echocardiogram. Cardiac computed tomography (CT) was performed to better define the septal anatomy. As the anatomy on cardiac CT was considered unfavorable for percutaneous intervention, the patient underwent successful surgical repair.Anomalous left anterior descending coronary artery in a pediatric patient with Fallot tetralogy
Cardiac CT was performed in a 3-year-old patient (weight, 12.4 kg; heart rate, 100 beats/minute) with tetralogy of Fallot (pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy) to rule out coronary anomalies before surgical correction. A shunt graft from the brachiocephalic trunk to the pulmonary artery had been placed in the patient at the age of 8 months. Data were acquired in free breathing using dual-source CT (DSCT). Fifteen milliliters of contrast agent (2 mL/second) was injected, followed by 20 mL of saline chaser.
