Percutaneous Coronary Intervention in Coronary Artery Aneurysms; Technical Aspects. Report of Case Series and Literature Review.

Coronary Artery Aneurysms (CAAs) in both symptomatic and asymptomatic patients are associated with poor long-term outcomes. The best treatment option for CAAs remains a subject of debate. The underlying pathology is not well understood, randomised controlled trials and supportive data are lacking and there is no consensus on treatment plan. The recommended therapies include medical management, percutaneous or surgical exclusion of the aneurysm or coronary artery bypass grafting surgery (CABG). Percutaneous coronary intervention (PCI) can be technically challenging even with a suitable anatomy, specifically in acute coronary syndrome (ACS). We report case series of CAAs presenting as ACS and focus on PCI treatment option.
