A Case of Coronary Air Embolism of the Left Coronary Arteries that Manifested as Cardiogenic Shock

摘要

Coronary air embolism remains a serious complication of coronary catheterization despite performing careful procedure to prevent this. We report here on a case of massive coronary air embolism that was complicated by cardiogenic shock in a 52-year-old male patient with angina pectoris. The patient had a stenosis in the middle left anterior descending artery (LAD) and percutaneous coronary intervention (PCI) was planned for the LAD lesion. During PCI, inadvertent manipulation of a pressure line induced massive air embolism in both proximal left coronary arteries, and this manifested as cardiogenic shock. The patient recovered after supportive measures and successive intracoronary injections of nitroglycerin and then he eventually underwent successful PCI.
