Observational study of anomalous coronary artery disease and interventions, in a real-life large group of contemporary patients undergoing cardiac procedures

Coronary heart disease involving anomalous coronary arteries can have implications on the prognosis, revascularization methods pose technical challenges in achieving successful outcomes. The accurate estimates on the prevalence of anomalous coronaries in a contemporary large series of patients are not available in Sri Lanka. The types of such anomalies and the outcomes of interventional procedures in them is hitherto not known.A retrospective study of 5093 consecutive cardiac cathlab procedures over 8 years was conducted, which showed a prevalence of anomalous coronaries in 1.51% of the records (involving 45 males and 15 females with a mean age of 59 years). Of this group, 22 percutaneous coronary interventions involving anomalous coronary arteries were identified. Multiple coronary anomalies were also seen in 2 patients. All of the 22 cases (100%) requiring intervention, were completed successfully by PCI without any in hospital major adverse cardiac/cerebral events (MACCE) or serious complications, despite the procedures requiring additional hardware or maneuvers for successful completion of PCI of the anomalous coronary arteries.
