Background: Chest trauma is among the most common types of trauma, corresponding to 10% of trauma patients admitted to hospitals. In the military setting, thoracic trauma was reported as a significant cause of death. With well-timed treatment, chest trauma is regarded as survivable. Emergency thoracotomy (ET) is considered when the patient with trauma to the chest needs immediate resuscitation. Survival rate is reported as low as 1% in some reports and 20% in others. The survival rate depends on injury mechanism, protocols for intervention, and other decompressive procedures.

Objectives: To determine parameters that may impact survival of ET.

Methods: We conducted a retrospective cohort study to compare prehospital and in-hospital data regarding ET in the emergency department (ED) versus the operating room (OR).

Results: Between 2009 and 2017, 6532 casualties presented to the ED; 1125 with trauma to the chest. Fifty-four of those with chest trauma underwent ET in the hospital (4.8%), 22 (41%) in the ED, and 32 (59%) in the OR. The overall mortality of the ET subgroup was 48%. With regard to thoracotomies, 19/22 of patients (86%) who underwent ET in the ED died compared to 2/28 in the OR (13%).

Conclusions: Utilizing ET after chest trauma with appropriate clinical indications, well-trained personnel, and prompt transportation poses a significant challenge, but may be associated with better survival than that reported previously with military casualties. Adoption of indications and timed allocation to the OR may improve outcomes with chest trauma casualties.

Background: Unicuspid and bicuspid aortic valve (BAV) are congenital cardiac anomalies associated with valvular dysfunction and aortopathies occurring at a young age.

Objectives: To evaluate our experience with aortic valve repair (AVr) in patients with bicuspid or unicuspid aortic valves.

Methods: Eighty patients with BAV or unicuspid aortic valve (UAV) underwent AVr. Mean patient age was 42 ± 14 years and 94% were male. Surgical technique included: aortic root replacement with or without cusp repair in 43 patients (53%), replacement of the ascending aorta at the height of the sino-tubular junction with or without cusp repair in 15 patients (19%), and isolated cusp repair in 22 patients (28%).

Results: The anatomical structure of the aortic valve was bicuspid in 68 (85%) and unicuspid in 12 patients (15%). Survival rate was 100% at 5 years of follow-up. Eleven patients (13.7%) underwent reoperation, 8 of whom presented with recurrent symptomatic aortic insufficiency (AI). Late echocardiography in the remaining 69 patients revealed mild AI in 63 patients, moderate recurrent AI in 4, and severe recurrent AI in 2. Relief from recurrent severe AI or reoperations was significantly lower in patients who underwent cusp repair compared with those who did not (P = 0.05). Furthermore, the use of pericardial patch augmentation for the repair was a predictor for recurrence (P = 0.05).

Conclusions: AVr in patients with BAV or UAV is a safe procedure with low morbidity and mortality rates. The use of a pericardial patch augmentation was associated with higher repair failure.
