Coronary artery air embolism causing pulmonary edema secondary to acute coronary syndrome in a diver.

Air embolism in the coronary arteries is a known complication of coronary angiography. Diving is a non-iatrogenic cause of arterial air embolism, commonly presenting with neurological and musculoskeletal symptoms. This is the first known case of coronary air embolism confirmed on coronary angiography in a diver presenting with pulmonary edema secondary to acute coronary syndrome. The possible mechanisms of coronary air embolism during a dive are reviewed in this article.
