“…The dynamic ECG changes seen in this patient, starting with hyperacute T waves in the distribution of the affected vessel, followed by ST-segment elevations ( Figures 1 and 2 ), have also been described by Leong and Brown ( 3 ). The mechanisms of dissection in TCAD include intimal tearing with propagation to the media, platelet activation and aggregation, thrombosis, and vasospasm ( 4 ). In terms of the mechanism of injury, TCAD can occur after a wide variety of traumatic mechanisms that involve blunt trauma to the chest, motor vehicle accidents with and without airbag deployment ( 5 , 6 ), and sports-related injuries.…”
