ABSTRACT
The stone heart syndrome is defined as an ischemic systolic contracture of the heart and also termed contractile cardiac arrest. It was first described in 1972 by the American cardiac surgeon Denton Cooley, who observed this phenomenon during bypass surgery. It is mostly the result of prolonged cardiac arrest where myocardial cells suffer hypoxia or anoxia. Insufficient forward blood flow and a decreased pressure gradient in the central aorta lead to reduced coronary perfusion. The resulting anaerobic metabolism causes an ischemic contracture as described in the stone heart syndrome. This article presents three cases of patients with traumatic cardiac arrest (TCA) and myocardial contracture in postmortem computed tomography (PMCT) and discuss the origins of the stone heart syndrome as well as its implications in cardiopulmonary resuscitation.
