Ventricular fibrillation caused by massive right coronary air embolism: a case report

Egypt Heart J. 2025 Jan 6;77(1):2. doi: 10.1186/s43044-024-00592-1.

Abstract

Background: Coronary air embolism is a rare but severe complication of coronary interventions.

Case presentation: We present a case of a massive air embolism in the right coronary artery during percutaneous coronary intervention, resulting in ventricular fibrillation. The patient was successfully resuscitated with electric defibrillation, leading to full recovery and TIMI 3 coronary flow. The final fractional flow reserve showed no residual coronary microvascular dysfunction.

Conclusion: Our finding suggests that inducing strong myocardial contractions with a cardioverter defibrillator may effectively disperse large air emboli and restore coronary circulation.
