Coronary pseudoaneurysm secondary to blunt chest trauma.

A 26-year-old man suffered a severe impact in a car crash. Computed tomography showed an image suspicious for coronary injury (Fig. 1a). Coronary angiography (Fig. 1b, Supplementary Video 1) revealed a pseudoaneurysm of the first diagonal branch. Sealing was cancelled because of spontaneous healing (Fig. 1c, Supplementary Video 2). Pseudoaneurysm disappeared and coronary artery remained normal after 6 months (Fig. 1d).
