Abstract

Background: Coronary air embolism (CAE) is a complication that can lead to catastrophic outcomes, including myocardial infarction, stroke, and death. It is reported to occur during cardiac catheterization, within a few hours after cardiac surgery, or as a result of chest trauma. This is a case report of delayed coronary air embolism following cardiac surgery.

Case presentation: A 58-year-old female presented with New York Heart Association (NYHA) Class II symptoms resulting from severe, highly eccentric anterior mitral regurgitation from a bio-prosthetic valve. She had preserved ejection function and a total calcium score of zero. This patient underwent a re-do mechanical mitral valve replacement. Two days post-surgery, she was brought to the catheterization laboratory with signs and symptoms suggestive of an inferior myocardial infarction (MI) and complete heart block (CHB). Her symptoms and ST changes resolved immediately after the introduction of angiographic contrast. Angiography revealed no occlusion in the right coronary artery (RCA).

二尖瓣置换术后迟发性冠状动脉空气栓塞1例。

背景：冠状动脉空气栓塞（CAE）是一种并发症，可导致灾难性的后果，包括心肌梗死、中风和死亡。据报道，它发生在心导管插入术中，心脏手术后几小时内，或由于胸部创伤。本文报告一例心脏手术后迟发性冠状动脉空气栓塞。病例介绍：一名58岁女性，因生物瓣膜植入导致严重、高度偏心二尖瓣前返流而出现纽约心脏协会（NYHA） II级症状。她保留了射血功能，总钙评分为零。该患者接受了二次机械二尖瓣置换术。术后2天，患者被带到导管实验室，体征和症状提示下型心肌梗死（MI）和完全性心脏传导阻滞（CHB）。她的症状和ST改变在引入血管造影后立即消失。血管造影显示右冠状动脉（RCA）无闭塞。
