Ventricular septal rupture and partial left ventricular posterior wall tear resulted from blunt chest trauma

Cardiac contusion and valvular injuries are the most common cardiac injuries after a blunt traumatic chestinjury.1 But ventricular septal rupture （VSR） is a rare finding after a blunt chest wall trauma.2 Here we report a 16 years old young man with no medical history who sustained a chest wall injury after a bookshelf falling on his left chest. He was hospitalized because of his chest pain and heaviness. Initial physical examination showed parasternal Ⅲ-Ⅳ systolic murmur. ECG showed a complete right bundle branch conduction blockage.
