Delayed presentation of cardiac injury four weeks after stabbing

Penetrating trauma to the heart has a high associated mortality due to significant hemorrhage, coronary artery injury, and cardiac tamponade. Such sequelae progress rapidly, often leading to death before reaching hospital. We report a case of delayed presentation following a stab injury to the right ventricle. This case highlights the mechanisms that may facilitate a delayed presentation and the importance of appropriate investigation when suspicion of cardiac injury is high.
