Diagnostic workup and treatment options for aneurysmal coronary artery disease

Coronary artery aneurysms and coronary ectasia are defined as focal or diffuse dilation of the coronary arteries, respectively. Although frequently silent and detected as incidental findings at coronary angiography or computed tomography, coronary aneurysms have been associated with different clinical conditions, including silent ischemia and acute coronary syndromes, and with poor clinical outcomes. The optimal management still remains unsettled, as randomized data are lacking and treatment with either surgical or percutaneous procedures faces significant challenges. This review aims to provide an update on the classification, etiopathogenesis, diagnostic workup, and treatment of aneurysmal coronary disease.
