Key result

Successful anterior STEMI PCI precedes unprecedented complete AV block and cardiac arrest two hours later.

  • n=1

Why the study?

The occurrence of high-degree conduction disturbances after percutaneous reperfusion with patent stent placement, rather than before revascularization, is unprecedented and raises clinical questions.

Overview

Post-PCI conduction disturbances in STEMI merit vigilance; single case report leaves open incidence, predictors, and practice implications.

Structured PICO

P
Population
A 51-year-old male chronic smoker and diabetic presenting with extensive anterior STEMI who developed complete atrioventricular block and cardiac arrest after percutaneous coronary intervention.
I
Intervention
Percutaneous revascularization by angioplasty and placement of an active stent on the anterior interventricular coronary artery
O
Outcome
Development of 3rd degree atrioventricular block and increased ST elevation post-revascularization

This case highlights an unusual presentation of complete AV block occurring after successful percutaneous revascularization for anterior STEMI, despite a patent stent.

Limitations

  • Single case report
  • Exact pathophysiological mechanism (e.g., stent thrombosis with spontaneous lysis vs. prolonged vasospasm) remains uncertain

Cite This Study

Larsen Clarck Moumpala Zingoula (2021) conducted a case report in ST-segment elevation myocardial infarction (STEMI) complicated by complete atrioventricular block (n=1). Percutaneous Revascularization was evaluated on Development of complete atrioventricular block and cardiac arrest. A 51-year-old man with an extensive anterior STEMI developed an unprecedented complete atrioventricular block and cardiac arrest two hours after successful percutaneous coronary revascularization.
