Key result
Late percutaneous coronary intervention performed more than four days after symptom onset successfully restored sinus rhythm within 48 hours in a patient with inferior wall MI and complete AV block.
Why the study?
There are no clear guidelines for time to PCI in late-presenting myocardial infarction with CAVB, and studies evaluating outcomes of primary PCI in this scenario are scarce.
Does late percutaneous coronary intervention restore sinus rhythm in patients with late presenting inferior wall myocardial infarction and complete atrioventricular block?

Does late percutaneous coronary intervention restore sinus rhythm in patients with late presenting inferior wall myocardial infarction and complete atrioventricular block?
Late PCI (>4 days post-symptom onset) successfully restored sinus rhythm in a patient with inferior wall MI and complete AV block, suggesting a potential benefit of late revascularization in this setting where guidelines are currently unclear.
Answers are grounded in this paper and cite their sources.
Late PCI may restore sinus rhythm in late-presenting inferior MI with CAVB; hypothesis-generating for timing guidelines.
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.

Liegise et al. (2023) conducted a case report in Inferior wall myocardial infarction with complete AV block (n=1). Late percutaneous coronary intervention (PCI) was evaluated on Recovery of sinus rhythm. Late percutaneous coronary intervention performed more than four days after symptom onset successfully restored sinus rhythm within 48 hours in a patient with inferior wall MI and complete AV block.
