Acquired causes include atherosclerosis in adults, Kawasaki disease in children and<unk>  catheterization. With the invention of drug eluting stents, there has been more cases implying stents lead to<unk><unk> s. The pathophysiology, although not completely understood, might be comparable to that of<unk> s of larger vessels. This includes disruption of the<unk> al media, weakening of the<unk> al wall, increased wall strain and slow dilatation of the<unk><unk>  portion. It can also be congenital. The following risk factors are thought to be associated with<unk> s: # Individual's genetic make-up, especially in patients with congenital<unk> s #<unk><unk>  disease (atherosclerosis) # Vasculitic and connective tissue diseases (Kawasaki and Marfan) # Intracoronary manipulation leading to local wall stress (stent placement, angioplasty, brachytherapy) # Post-infectious as a consequence of direct wall infiltration or immune complex deposition
