Mechanical intervention and coronary artery aneurysm.
Coronary artery aneurysms after intervention are rare, and most are pseudoaneurysms rather than true aneurysms. Stent infection has been associated with mycotic aneurysm formation, as is the use of drug-eluting stents (DES). The antiproliferative and immunomodulatory properties of DES may reduce the local host defense mechanism and thus increase the chance of infection and contribute to aneurysm formation. Mechanical factors during implantation also play an important role in aneurysm formation. We report 3 cases of complications of mechanical interventions in coronary arteries.
