Repeated anatomical pulmonary resection for metachronous ipsilateral second non-small cell lung cancer.
We investigated the surgical outcomes of repeated pulmonary resection for metachronous ipsilateral second non-small cell lung cancer (NSCLC). ⋯ Reanatomical pulmonary resection showed acceptable oncologic outcomes for metachronous ipsilateral second NSCLC. The non-CP procedure was technically challenging; however, both oncologic and surgical results were feasible compared with the CP. This procedure might be a promising novel strategy for properly selected ipsilateral second NSCLC.

Multicenter Study Observational StudyImpact of perioperative course during cardiac surgery on outcomes in patients 80 years and older.
To describe the associations among preoperative characteristics, intraoperative and postoperative factors, and mortality and morbidity after open-heart surgery in patients age ≥80 years. ⋯ Our findings emphasize the importance of careful referral regarding the procedural burden for very elderly patients and may provide support for informed patient discussions about prognosis and recovery.

Multicenter Study Observational StudyIntermediate-term outcomes of aortic valve replacement using a bioprosthesis with a novel tissue.
The COMMENCE trial was conducted to evaluate the safety and effectiveness of an aortic bioprosthesis with novel RESILIA tissue (Edwards Lifesciences, Irvine, Calif). Reports of early noncalcific valve failure resulting from thrombosis or leaflet tears in other valves warrant careful evaluation of early valve performance. ⋯ Safety and hemodynamic performance of this aortic bioprosthesis with RESILIA tissue at 4 years are favorable. This novel tissue does not appear to result in unexpected early thrombosis events or noncalcific structural valve deterioration.

Use of patient-specific computational models for optimization of aortic insufficiency after implantation of left ventricular assist device.
Aortic incompetence (AI) is observed to be accelerated in the continuous-flow left ventricular assist device (LVAD) population and is related to increased mortality. Using computational fluid dynamics (CFD), we investigated the hemodynamic conditions related to the orientation of the LVAD outflow in these patients. ⋯ Using CFD simulations, we demonstrated that patients who developed de novo AI have greater rWSS at the aortic root, and their outflow grafts were placed closer to the aortic roots than those patients without de novo AI.
