Summary An elderly gentleman presenting late with inferior wall myocardial infarction and complete heart block underwent revascularization of an occluded proximal right coronary artery more than four days after the onset of symptoms and recovered sinus rhythm within 48 hours of the procedure. There are no clear guidelines for time to percutaneous coronary intervention (PCI) in late presenting myocardial infarction with complete atrioventricular blocks (CAVB), and studies looking at outcomes of primary PCI in this situation appears to be scarce. The case presented here is a good example of the relevance of late PCI.
