Repair of coronary sinus shear stress injury following blunt chest trauma using adenosine-induced asystole

Blunt chest trauma following a motor vehicle accident is the leading cause of non-penetrating cardiac injuries. Major structural heart injuries are fatal due to acute tamponade. We present the case of a 17-year-old male who was involved in a motor vehicle accident. He had an isolated coronary sinus rupture, which was successfully repaired. We propose a potential mechanism implicated in this rare injury, and we summarize a novel repair technique with adenosine-induced transient asystole.
