Estimating Mortality Risk for Adult Congenital Heart Surgery: An Analysis of The Society of Thoracic Surgeons Congenital Heart Surgery Database.
Adjustment for case mix is critical to accurate outcomes analysis in congenital heart surgery. Established tools encompass all age groups and are not specific to the growing population of adults undergoing congenital heart operations. We derived an empirically based adult congenital heart surgery (ACHS) mortality score. ⋯ Risk estimation based on the aggregate of all age groups is suboptimal when analyzing outcomes specifically among adults. An empirically based ACHS mortality score can facilitate case-mix adjustment by providing accurate estimation of mortality risk for adults.

There is growing concern over the effect of starting non-emergent cardiac surgery later in the day on clinical outcomes and resource utilization. Our objective was to determine the differences in patient outcomes for starting non-emergent cardiac surgery after 3 pm. ⋯ Starting non-emergent cardiac cases later in the day is associated with 2 times higher absolute and risk-adjusted mortality. These data should be carefully considered, not only by surgeons and patients but also in the context of the operating room system when scheduling non-emergent cardiac cases.

Comparative Study
Multidisciplinary Treatment for Stage IIIA Non-Small Cell Lung Cancer: Does Institution Type Matter?
Improved survival of patients with early-stage non-small cell lung cancer (NSCLC) undergoing resection at high-volume centers has been reported. However, the effect of institution is unclear in stage IIIA NSCLC, where a variety of neoadjuvant and adjuvant therapies are used. ⋯ Stage IIIA NSCLC patients undergoing resection at academic centers had lower 30-day mortality and increased overall survival compared with patients treated at community centers, possibly due to higher patient volume and an increased rate of neoadjuvant chemotherapy.

Acute kidney injury (AKI) continues to complicate cardiac operations. We sought to determine whether nadir oxygen delivery (DO2) on cardiopulmonary bypass (CPB) was a risk factor for AKI while also accounting for other postoperative factors. ⋯ Postoperative hypotension on POD0 or POD1 and low DO2 on CPB both independently increase the AKI risk in cardiac surgical patients.

Despite improved results with surgical therapy for acute type A aortic dissection (ATAAD), there remains a lack of consensus regarding the optimal method of cerebral protection and circulation management during ATAAD. The purpose of this study is to determine whether in the setting of antegrade cerebral perfusion, moderate hypothermic circulatory arrest (MHCA) provides equivalent cerebral and visceral protection as deep hypothermic circulatory arrest (DHCA) for patients undergoing emergent ATAAD repair. ⋯ Moderate HCA with uSACP is an effective circulation management strategy that provides excellent cerebral and visceral protection during emergent ATAAD repair. In the setting of antegrade cerebral perfusion, deep hypothermia does not provide any additional benefit.
