Abstract

Penetrating cardiac injuries (PCIs) are highly lethal, and a sternotomy is considered mandatory for suspected PCI. Recent literature suggests pericardial window (PCW) may be sufficient for superficial cardiac injuries to drain hemopericardium and assess for continued bleeding and instability. This study objective is to review patients with PCI managed with sternotomy and PCW and compare outcomes. All patients with penetrating chest trauma from 2000 to 2016 requiring PCW or sternotomy were reviewed. Data were collected for patients who had PCW for hemopericardium managed with only pericardial drain, or underwent sternotomy for cardiac injuries grade 1-3 according to the American Association for the Surgery of Trauma (AAST) Cardiac Organ Injury Scale (OIS). The PCW+drain group was compared with the Sternotomy group using Fisher's exact and Wilcoxon rank-sum test with P<0.05 considered statistically significant. Sternotomy was performed in 57 patients for suspected PCI, including 7 with AAST OIS grade 1-3 injuries (Sternotomy group). Four patients had pericardial injuries, three had partial thickness cardiac injuries, two of which were suture-repaired. Average blood drained was 285 mL (100-500 mL). PCW was performed in 37 patients...Continue Reading

Cardiotoxicity

Cardiotoxicity refers to the muscle damage or dysfunction of heart electrophysiology caused by drug intake or due to disease complications. It is a well-known side effect of several cytotoxic drugs, especially of the anthracyclines and can lead to long term morbidity. Here is the latest research.
