Mortality Trends in Pediatric and Congenital Heart Surgery: An Analysis of The Society of Thoracic Surgeons Congenital Heart Surgery Database.
Previous analyses of The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database have demonstrated a reduction over time of risk-adjusted operative mortality after coronary artery bypass grafting. The STS Congenital Heart Surgery Database (STS CHSD) was queried to assess multiinstitutional trends over time in discharge mortality and postoperative length of stay (PLOS). ⋯ This 16-year analysis of STS CHSD reveals declining discharge mortality over time, especially for more complex operations.

Comparative Study
The Impact of Deep Versus Moderate Hypothermia on Postoperative Kidney Function After Elective Aortic Hemiarch Repair.
There remains concern that moderate hypothermic circulatory arrest (MHCA) with antegrade cerebral perfusion (ACP) may provide suboptimal distal organ protection compared with deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP). We compared postoperative acute kidney injury (AKI) in in patients who underwent elective hemiarch repair with either DHCA/RCP or MHCA/ACP. ⋯ We applied the sensitive RIFLE criteria to examine AKI in patients undergoing elective aortic hemiarch replacement for aneurysmal disease. Baseline renal dysfunction, lower ejection fraction, and longer CPB time are independent predictors of AKI. Compared with DHCA/RCP, our data suggest that an MHCA/ACP cerebral protection strategy does not appear to be associated with worse postoperative renal outcomes.

Multicenter Study Clinical Trial
Immediate Postoperative Oral Nutrition Following Esophagectomy: A Multicenter Clinical Trial.
Immediate start of oral intake is beneficial following colorectal surgery. However, following esophagectomy the safety and feasibility of immediate oral intake is unclear, thus these patients are still kept nil by mouth. This study therefore aimed to determine the feasibility and safety of oral nutrition immediately after esophagectomy. ⋯ Immediate start of oral nutrition following esophagectomy seems to be feasible and does not increase complications compared to a retrospective cohort and literature. However, if complications arise an alternative nutritional route is required. This explorative study shows that a randomized controlled trial is needed.

Comparative Study
Recurrence and Survival After Segmentectomy in Patients With Prior Lung Resection for Early-Stage Non-Small Cell Lung Cancer.
Lobectomy is the standard of care for patients with early-stage non-small cell lung cancer (NSCLC). However, the treatment of choice for patients with prior lung resection and a second primary NSCLC has not been established. We compared rates and patterns of recurrence and survival in patients with and without prior lung resection treated by segmentectomy and determined predictors of recurrence. ⋯ Segmentectomy is a reasonable option for patients with early-stage NSCLC who have had a prior lung resection. It results in similar survival but trends toward lower recurrence-free survival compared with patients undergoing primary resection.

Transcatheter mitral valve replacement using balloon-expandable valves is an emerging technique for the treatment of patients with significant mitral regurgitation who have been judged to be inoperable owing to significant mitral valve annulus calcification. Although initial reports have been promising, there remains a lack of consensus as to how to plan for transcatheter mitral valve replacement deployment in terms of appropriateness, sizing, and positioning to mitigate the risks of valve displacement and paravalvular regurgitation. ⋯ The second case was thereafter performed successfully using iterative learning and the application of specific preprocedural planning techniques acquired from a root cause analysis of the first case. We describe our experience with both cases and the specific planning principles required to prevent transcatheter mitral valve replacement displacement in patients with mitral valve annulus calcification.
