Diagnosis and treatment of spontaneous coronary artery pseudoaneurysm: Rare anomaly with potentially significant clinical implications.
Spontaneous coronary artery pseudoaneurysm (PSA, false aneurysm) is an extremely rare occurrence with the precise incidence unknown. It is defined as an outwardly bulging monolayer or double layer within the coronary artery that lacks all 3 layers (intima, media, and adventitia) of the arterial wall. Coronary PSA commonly occurs from arterial dissection or perforation induced by catheter intervention, infection, pregnancy, or trauma. Traumatic dissection or perforation of the coronary artery after a percutaneous coronary intervention (PCI) remains the most common cause. Such cases may progress to myocardial ischemia, acute myocardial infarction, or acute coronary artery rupture causing death from cardiac tamponade. Intravascular ultrasound or cardiac computed tomography may aid in the diagnosis. Treatment options include PCI with a covered stent, bare or drug-eluting stent, coil embolization, coronary artery bypass graft with isolation of the PSA, or conservative management with vigilant clinical follow-up. In this review, we sought to describe the diagnosis, etiology, treatment, and the limited literature on spontaneous coronary artery PSA. © 2017 Wiley Periodicals, Inc.
