Early thoracotomy for stab wounds of the heart.

Fifteen consecutive patients with stab wounds of the heart are reviewed. The left ventricle was stabbed in six patients and right ventricle in four. Sinus tachycardia was present in 54% and hypotension in 67% of cases. Central venous pressure recorded in ten patients was elevated in all but one. Generalized ST segment elevation was the rule among the available preoperative recordings. One patient had right bundle branch block. Thirteen of the fifteen patients had a thoracotomy and two had pericardiocentesis only. Sixty nine percent of the thoracotomies were performed within two hours of the injury. There was only one death of a patient who arrived with no blood pressure or heart sounds. An average follow-up of 20 months revealed long-term sequela of an asymptomatic ventricular aneurysm in one patient. Our unusually gratifying results support the approach of emergency thoracotomy in patients with penetrating cardiac trauma.
