Table 2 Results for detected coronary artery anomalies

From: Visualization of anomalous origin and course of coronary arteries in 748 consecutive symptomatic patients by 64-slice computed tomography angiography

Subgroup 1: Absent left main trunk (split origination of LCA); not found
Subgroup 2: Anomalous location of coronary ostium within aortic root or near proper aortic sinus of Valsalva (for each artery); not found
Subgroup 3: Anomalous location of coronary ostium outside normal "coronary" aortic sinuses
  • High origin of coronary arteries: left main coronary artery and right
coronary artery; normal termination
  ▪ n = 1 (0.1%)
  ▪ gender: female
  ▪ age: 19 years
  ▪ symptoms: syncope
  ▪ known coronary artery anomaly
  ▪ initial diagnosis: ICA
Subgroup 4: Anomalous location of coronary ostium at improper sinus (which may involve joint origination or "single" coronary pattern)
  • Right coronary artery from left anterior Sinus of Valsalva with further
vessel course between aorta and pulmonary trunk (n = 8; 1.1%)
  separate ostium with left main coronary artery, normal termination
(Subgroup 4a)
  ▪ n = 7 (0.9%)
  ▪ male:female = 4:3
  ▪ age: 43.7 ± 18.2 years (range: 17-73 years)
  ▪ symptoms: chest-pain
  ▪ known coronary artery anomaly (n = 3)
  ▪ initial diagnosis: ICA (n = 1); echocardiography (n = 2)
  common ostium with left main coronary artery, single coronary
artery, normal termination (Subgroup 4b)
  ▪ n = 1 (0.1%)
  ▪ male
  ▪ age: 26 years
  ▪ symptoms: chest-pain
  ▪ unknown coronary artery anomaly
  • Left coronary artery from right anterior Sinus of Valsalva with further
vessel course between aorta and pulmonary trunk
  Common ostium with RCA and no circumflex ramus, single coronary
artery, intramyocardial course of proximal left anterior descending
coronary artery (Subgroup 4c)
  ▪ n = 1 (0.1%)
  ▪ gender: male
  ▪ age: 58 years
  ▪ symptoms: chest-pain
  ▪ known coronary artery anomaly
  ▪ initial diagnosis: ICA
  • Circumflex ramus from right anterior Sinus of Valsalva with further
vessel course in posterior atrio-ventricular groove (Subgroup 4d)
  ▪ n = 7 (0.94%)
  ▪ male:female = 6:1
  ▪ age: 46.3 ± 21.1 years (range: 15-65 years)
  ▪ symptoms: chest-pain
  ▪ known coronary artery anomaly (n = 1)
  ▪ initial diagnosis: echocardiograpy (n = 1)
