We present a case of an isolated large ventricular septal defect (VSD) following blunt chest trauma in a motor vehicle accident in the patient with preexisting mechanical mitral valve. Transthoracic echocardiography revealed a large muscular VSD with significant left to right shunt along with septal edema. Surgical repair was performed in view of Qp:Qs of 2.5 with significant hemodynamic instability despite intra-aortic balloon pump. The ventricular septal defect was found in apical muscular

To conclude, minor looking external injury might contain devastating damage inside, especially with patients on anti-coagulant therapy.
