Comment on: Dual LAD with anomalous origin of long LAD from right coronary sinus: A variant of type VI LAD

A 50‐year‐old gentleman was referred to our department for computed tomography (CT) coronary angiography with complaints of pain on the left side of the chest and cold sweats since 4 days. CT coronary angiography, done on a 64‐slice CT (Somatom Sensation‐64, Erlangen, Germany), showed evidence of dual LAD. The short LAD was arising from the left main coronary artery and coursing in the proximal anterior interventricular groove and terminated after giving a large septal and one large diagonal branch. The long LAD was found arising from the right coronary sinus in close proximity to the right coronary artery (RCA) ostium [Video 1]. It showed epicardial course between the aortic root and right ventricular outflow tract (RVOT) and reached the mid anterior interventricular groove [Figures 1 and 2]. No significant disease was noted in either LAD; however, severe plaque‐induced narrowing was found in the large diagonal arising from short LAD.
