Cardiac Trauma: A Review of Penetrating and Blunt Cardiac Injuries.

Abstract

Cardiac injuries pose challenging diagnostic and management dilemmas. Cardiac trauma can be classified by mechanism into blunt and penetrating injuries. Penetrating trauma has an overall higher mortality and is more likely to require operative intervention. Due to the lethality of any cardiac injury, prompt diagnosis and treatment is critical for survival. The initial management of suspected cardiac injury should start with Advanced Trauma Life Support (ATLS) protocols followed shortly by directed diagnosis and management, which usually begins with a focused assessment with sonography in trauma (FAST) examination. In contrast to traditional ATLS protocols, some centers have adopted an assessment of "circulation before "airway" and "breathing"; however, this is an evolving concept. In this article, we provide an overview on the management of penetrating and blunt cardiac injuries, including use of physical exam, laboratory tests, imaging, and surgery.
