Our objective was to determine the incidence and optimal management of chylothorax after pulmonary resection with complete thoracic mediastinal lymph node dissection (MLND). ⋯ Chylothorax after pulmonary resection and MLND occurred in 1.4% of patients. Its incidence was higher in those with pathologic N2 disease and those who underwent robotic resection. Nonoperative therapy is almost always effective.

Review Meta Analysis
In search of the ideal pulmonary blood source for the Norwood procedure: a meta-analysis and systematic review.
A clear consensus regarding the optimal source of pulmonary blood flow in patients with hypoplastic left heart syndrome undergoing the Norwood procedure is lacking. ⋯ Our pooled analysis demonstrated no survival benefit for the MBTS or RV-PAS in patients undergoing the Norwood procedure. There appears to be an advantage with the RV-PAS with regard to interstage mortality at the cost of an increased rate of shunt intervention.

Randomized Controlled Trial Multicenter Study
Acute kidney injury after on-pump or off-pump coronary artery bypass grafting in elderly patients.
An exploratory analysis of the German Off Pump Coronary Artery Bypass Grafting in Elderly Patients (GOPCABE) trial was performed to investigate the effect of off-pump coronary artery bypass grafting (CABG) on kidney function after the operation. ⋯ AKI was common in elderly patients undergoing CABG, but deterioration of kidney function requiring renal replacement therapy was a rare event. Off-pump CABG was not associated with decreased rates or reduced severity of AKI in elderly patients.

Randomized Controlled Trial
Transcatheter versus surgical aortic valve replacement in patients with prior coronary artery bypass graft operation: a PARTNER trial subgroup analysis.
The Placement of Aortic Transcatheter Valves (PARTNER) trial reported a reduced rate of mortality in patients with previous coronary bypass grafting (CABG) operation who received surgical aortic valve replacement (SAVR) in comparison with transcatheter aortic valve replacement (TAVR). We sought to further evaluate these groups. ⋯ The 2-year follow-up of patients with a history of previous CABG operation in the PARTNER trial demonstrated improved outcomes with SAVR in comparison with TAVR. Further longitudinal assessment is necessary to corroborate these findings and to understand the possible causes.

The risk of clinically apparent, periprocedural stroke after thoracic endovascular aortic repair (TEVAR) due to dislodgement and embolization of aortic debris from intravascular manipulation of guidewires, catheters, and large-bore delivery systems ranges between 2% and 6% and has been associated with increased postoperative mortality. The rate of clinically silent cerebral ischemia is yet unknown, but may be even higher. ⋯ Thoracic endovascular aortic repair resulted in a high incidence of new foci of restricted diffusion on cerebral DW-MRI in a pattern suggestive of periprocedural embolization. Although multiple lesions per patients were found, these lesions were not associated with apparent neurologic deficits during the in-hospital period. Further developments in TEVAR should be directed toward reducing the risk of periprocedural cerebral embolization.
