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.
背景
冠状动脉空气栓塞是冠状动脉介入治疗中一种罕见但严重的并发症。
病例报告
我们报告一例经皮冠状动脉介入治疗期间右冠状动脉发生大量空气栓塞，导致心室颤动的病例。患者通过电除颤成功复苏，实现完全康复且冠状动脉血流达到TIMI 3级。最终的血流储备分数显示无残余冠状动脉微血管功能障碍。
结论
我们的研究结果表明，使用心脏复律除颤器诱发强烈心肌收缩可能有效驱散大量空气栓子并恢复冠状动脉循环。
