Abstract
Coronary air embolism is a dreadful complication of cardiac intervention despite careful prevention. In literature reported complications of coronary air embolism ranges from clinically non significant events to cardiogenic shock, myocardial infarction and death. We report a case of massive coronary air embolism in right coronary artery, which results in hypotension and complete heart block in a 33 -year-old female undergoing elective closure of atrial septal defect (ASD) by percutaneous transcatheter intervention. The patient stabilized after timely measures like oxygen support, dopamine infusion, cardiac compression and repeated bolus injection of heparinized saline. She then underwent successful percutaneous ASD device closure.
