Overview
A coronary artery dissection refers to a split or a tear in the wall of the artery which compresses or compromises the lumen of the artery reducing blood flow. According to the NHLBI (National Heart Lung and Blood Institute) scheme, dissection is defined as an intraluminal filling defect or flap associated with a hazy, ground-glass appearance. This category is sub-classified using the NHLBI system for grading dissection types into type A, B, C, D, E and F.
