Penetrating cardiac trauma: findings, outcomes and prognostic factors in operated patients Introduction: Penetrating cardiac trauma (PCT) constitute a permanent surgical challenge due to it characteristics and high mortality. Aim: To describe the findings, outcomes and prognostic factors in PCT. Materials and Method: Cross-sectional descriptive study, review of prospective thoracic trauma protocols and surgical registries. Period January 1990-December 2017. All patients with PCT were included. Various variables are described and analyzed. Univariate and multivariate analysis were performed to identify factors associated with morbidity, neurologic dysfunction and mortality. Results: 220 patients PCT, 209 (95.0%) men, mean age 30.4 ± 13.3, median 27 years. Mechanism: Aggression in 202 (91.8%). The traumatic agent was cold steel in 186 (84.4%) and fire arm in 21 (9.5%). 169 (76.8%) patients presented with tamponade, 103 (46.8%) shock and 20 (9.1%) cardiopulmonary arrest. Approach was sternotomy in 157 (71.4%), left thoracotomy in 58 (26.4%). The most common injured areas were right ventricle in 110 (50.0%), left ventricle in 72 (32.7%). 135 (61.4%) patients needed postoperative ICU and 74 (33.6%) were transfused. Complications occurred in 60 (27.3%). Twenty-one (9.5%) were reoperated. Mortality 28 (12.7%). The postoperative median stay was 6 days (Range 1-150). Prognostic factors were identified. Discussion: Operated PCT are more frequent in men with stab wound, the most common injured area is the right ventricle. The morbidity and mortality is comparable with international series.
