Comparative StudyPropensity-matched comparison of video-assisted thoracoscopic with thoracotomy lobectomy for locally advanced non-small cell lung cancer.
We evaluated whether video-assisted thoracoscopic lobectomy for locally advanced non-small cell lung cancer could be performed safely and with acceptable long-term outcomes by our improved technique and compared with standard thoracotomy lobectomy in a well-balanced population. ⋯ With continued experience and optimized technique, video-assisted thoracoscopic lobectomy can be performed in the majority of cases without compromising perioperative outcomes and oncologic efficacy.

The effects of postoperative hematocrit on shunt occlusion for neonates undergoing single ventricle palliation.
Our primary objective was to test the effects of first postoperative hematocrit on early shunt occlusion for children undergoing systemic to pulmonary artery shunt placement. Because any intervention to reduce shunt occlusion is only beneficial if it reduces mortality or is, at least, mortality neutral, we also tested the effects of first postoperative hematocrit on in-hospital mortality. ⋯ Higher postoperative hematocrit levels are associated with early shunt occlusions in infants undergoing primary systemic to pulmonary artery shunt placement. Multicenter investigations are warranted to validate these findings and to determine ideal postoperative hematocrit targets for this population.

Patient-specific assessment of hemodynamics by computational fluid dynamics in patients with bicuspid aortopathy.
Hemodynamics related to eccentric blood flow may factor into the development of bicuspid aortic valve aortopathy. We investigated wall shear stress distribution by means of magnetic resonance imaging-based computational fluid dynamics in patients with a bicuspid aortic valve. ⋯ Computational fluid dynamics simulation is useful for precise evaluation of hemodynamics related to bicuspid aortic valve aortopathy. Such evaluation will advance our understanding of the disease pathophysiology and may facilitate molecular biological investigation.
