A novel surgical marking system for small peripheral lung nodules based on radio frequency identification technology: Feasibility study in a canine model.
We investigated the feasibility and accuracy of a novel surgical marking system based on radiofrequency identification (RFID) technology for the localization of small peripheral lung nodules (SPLNs) in a canine model. ⋯ Successful localization and wedge resection of pseudolesions with appropriate margins were accomplished in an experimental setting. Our RFID marking system has future applications for accurately locating SPLNs in a clinical setting.

Comparative StudyNeurodevelopmental outcomes in preschool survivors of the Fontan procedure.
The study objectives were to compare the neurodevelopmental outcomes of preschool survivors of the Fontan procedure with those of children with congenital heart disease undergoing biventricular repair and to investigate predictors of neurodevelopmental outcome for those with single ventricle congenital heart disease, including hypoplastic left heart syndrome. ⋯ In this cohort, unadjusted neurodevelopmental outcomes for preschool survivors of the Fontan procedure are similar to those for children with congenital heart disease undergoing biventricular repair for most domains. Among the patients undergoing the Fontan procedure, hypoplastic left heart syndrome was not associated with worse outcomes compared with other forms of single ventricle.

Computational fluid dynamics in patients with continuous-flow left ventricular assist device support show hemodynamic alterations in the ascending aorta.
Increased use of continuous-flow left ventricular assist devices for long-term mechanical support necessitates a better understanding of hemodynamic changes in the native heart and the ascending aorta. By using patient-specific computational models, correlations of potentially adverse hemodynamic conditions with the orientation of the left ventricular assist device outflow graft and their relationship with aortic insufficiency and ischemic events were investigated. ⋯ Computational fluid dynamic simulations using clinical image data indicate altered hemodynamic conditions after left ventricular assist device implantation. Consequently, the left ventricular assist device outflow graft should be placed so the jet of blood is aimed toward the lumen of the aortic arch to avoid turbulences that will increase wall shear stress and retrograde pressure of the aortic root. Further investigations are warranted to confirm these findings in a larger patient cohort.

Stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair: the STABILISE concept.
The study objective was to describe the Stent-Assisted Balloon-Induced Intimal Disruption and Relamination in Aortic Dissection Repair technique for aortic dissection repair using proximal descending aortic endografting with distal aortic relamination through bare-metal stent and balloon-induced intimal disruption with immediate intimal reapposition. ⋯ The Stent-Assisted Balloon-Induced Intimal Disruption and Relamination in Aortic Dissection Repair approach is a feasible endovascular technique that shows promise to achieve complete repair of the dissected aorta by inducing complete false lumen obliteration. The restoration of uniluminal flow in the thoracoabdominal aorta has the potential to improve long-term outcomes. Prospective, multicenter investigations are required to implement this strategy more broadly.
