Key result
Successful anterior STEMI PCI precedes unprecedented complete AV block and cardiac arrest two hours later.
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.
Case Report (n=1)
No
This case highlights an unusual presentation of complete AV block occurring after successful percutaneous revascularization for anterior STEMI, despite a patent stent.

Post-PCI conduction disturbances in STEMI merit vigilance; single case report leaves open incidence, predictors, and practice implications.
Conduction disturbances complicating acute myocardial infarction with persistent ST segment elevation are common, especially those of high degree in previous myocardial infarctions.Do these complications occur in the acute phase, before revascularization, with a poor prognosis immediately justifying myocardial reperfusion as well as the placement of an electro systolic training lead.However, their absence before revascularization to occur in post percutaneous reperfusion by angioplasty with placement of an active stent on the culprit artery, with an increase in the ST elevation, is unprecedented and raises as many questions as possible whereas the Stent in place remains permeable.We report the case of a patient presenting, initially, a 3rd degree atrioventricular block after percutaneous revascularization of an ST + extended anteriorly by angioplasty and placement of an active stent on the anterior interventricular coronary artery permeable after a second post-critical coronary angiography.

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.
