Tension Pneumopericardium Causing Cardiogenic Shock due to Blunt Injury to the Chest

Pneumopericardium is an exceptionally uncommon phenomenon in the setting of blunt polytrauma. It is imperative for trauma providers to identify tension pneumopericardium despite its rarity. A 22-year-old male motorcyclist presented to the hospital after colliding with a car going approximately 50 mph. The patient was hemodynamically unstable and had diminished breath sounds bilaterally. Bilateral chest tubes were placed, yielding little improvement in condition. While obtaining CT imaging, pneumopericardium was promptly identified. Pulses were lost immediately before pericardiocentesis, and resuscitative thoracotomy was performed. The pericardial sac was tense and an immediate gush of air released upon incising the sac. The patient was taken immediately to the Operating Room for further exploration and repair.

Racial Disparities in Mitral Valve Surgery: A Statewide Analysis

OBJECTIVE

Racial disparities in health care have come to the forefront. We hypothesized that Black race was associated with worse preoperative risk, lower repair rates, and worse outcomes among patients who underwent mitral valve surgery.

METHODS

All patients who underwent mitral valve repair or replacement with or without coronary artery bypass grafting from 2011 to 2020 in a statewide collaborative database were stratified into 3 racial groups, White, Black, and other. Preoperative characteristics, procedure type, and outcomes were evaluated.

RESULTS

A total of 9074 mitral valve operations were performed at 33 centers (Black 1009 [11.1%], White 7862 [86.6%]). Preoperative combined Society of Thoracic Surgeons morbidity and mortality was higher for Black patients (Black 32%, White 22%, other 23%, [P < .001]) because of a greater proportion of diabetes, hypertension, and chronic lung disease. White patients were more likely to undergo mitral repair (White 66%, Black 53.3%, other 57%; P < .001). Operative mortality was similar across racial groups (White 3.7%, Black 4.6%, other 4.5%; P = .36). After adjusting for preoperative factors, mitral etiology, and hospitals, race was not associated with mitral valve repair, complications, or mortality, but Black patients had higher odds of extended care facility utilization and readmission.

CONCLUSIONS

Contrary to our hypothesis, there was no difference in the odds of repair or operative mortality across races after accounting for risk and etiology. However, Black patients were more likely to be readmitted after discharge. These findings support a greater focus on reducing disparities in mitral valve surgery.
