[Use of 64-slice tomodensitometry after cardiac arrest].

Acute coronary occlusion is the leading cause of out-of-hospital cardiac arrest, so patients are usually referred for immediate coronary angiography and angioplasty. We report here the observation of such a patient who previously underwent a coronary artery bypass intervention and who had a difficult arterial access. Moreover, the nature of the grafts was unknown (saphenous and/or mammary arteries). Multi-slice cardiac tomo-densitometry was performed rather than a conventional coronary angiography and it allowed the analysis of native arteries and grafts. There was no stenosis and angioplasty was unnecessary.
