Sudden death after normal coronary angiography and possible causes

Abstract

Coronary angiography remains as the gold standard for the diagnosis of coronary artery disease. Serious complication due to coronary angiography is very rare and generally it is considered safe in experienced hands. Here, we would like to present two cases without severe stenosis in the coronary arteries suffering from cardiac arrest soon after the procedures, and draw attention to this lethal complication and review the possible causes of sudden death occurring after coronary angiography.

Attack of angina pectoris with low back pain alone: a case report

“… 7 , 8 Intervertebral disc degeneration resulting from occlusion of the middle sacral artery and subsequent lumbar ischemia is another possible cause of long-term low back pain. 9 Aortic or coronary artery dissection during CAG: Arterial dissection can manifest as progressively worsening chest pain, 10 , 11 which is typically described as abrupt in onset and tearing in nature. 12 Intraoperative peripheral embolism: Air emboli, thrombosis, platelet aggregation, detachment of atherosclerotic plaques, 13 – 15 and formation of cholesterol crystals during CAG can cause peripheral embolism.…”
