  • Title: Penetrating cardiac injuries.
    Author: Mittal V, McAleese P, Young S, Cohen M.
    Journal: Am Surg; 1999 May; 65(5):444-8. PubMed ID: 10231214.
    Abstract:
    Our objective was to determine the influence of several clinical factors on the survival of patients with penetrating wounds to the heart. A retrospective review of 80 consecutive penetrating cardiac injuries treated in a Level II urban trauma center from 1980 through 1994 were examined. Thirty-six patients (45%) had gunshot wounds (including 1 shotgun wound), and 44 (55%) had stab wounds. Intervention consisted of emergency room (ER) or operating room thoracotomy. We measured the effect of several clinical factors on morbidity and patient survival. Survival rate was 17 of 36 (47%) in gunshot injuries and 35 of 44 (80%) in stab injuries, with an overall survival rate of 52 of 80 patients (65%). The average age was 24 years (range, 9-53), and there were 3 female patients. Twelve patients (15%) had multiple cardiac injuries, and 63 (79%) had other associated injuries. Fourteen patients (17%) presented with no blood pressure, and 55 (69%) were hypotensive on admission. ER thoracotomy was performed on 7 of 52 survivors (13%) and 24 of 28 nonsurvivors (86%). Survival after ER thoracotomy was 7 of 31 patients (22%). A selective approach is recommended, because ER thoracotomy has a limited role in penetrating cardiac injury. A high index of suspicion, prompt resuscitation, and immediate definitive surgical management resulted in a high survival rate for these frequently lethal injuries.
