Introduction: The objective of this case report was to illustrate the diagnostic and intervention approach of anomalous right coronary artery (RCA).

Clinical Picture: A 60-year-old man presented with acute inferior myocardial infarction. Cardiac catheterisation revealed an anomalous RCA arising from the posterior coronary sinus as the infarct-related artery.

Treatment: Ad hoc percutaneous coronary intervention with stent implantation was performed using a few technical modifications.

Outcome: Good angiographic result was achieved within 90 minutes, with 260 mL of contrast used. Conclusion: A high index of suspicion and logical diagnostic and intervention approach are required for the proper management of anomalous RCA.

A 60-year-old chronic smoker had delayed presentation (>18 hours) of acute inferior myocardial infarction with electrocardiogram showing 1.0 mm ST-segment elevation in leads II, II, and aVF on admission to hospital. Subsequently, he developed sustained complete atrioventricular block with no ventricular escape which necessitated temporary pacing.
