Video-assisted thoracic surgery major lung resection can be safely taught to trainees.
Video-assisted thoracoscopic surgery (VATS) major lung resection for lung cancer has been an important part of thoracic surgical training program in our institution. In this study, we compared the results of VATS major lung resection performed by surgical trainees with those performed by experienced thoracic surgeons with specialist interest in VATS. ⋯ Video-assisted thoracic surgery major lung resection for early stage nonsmall-cell lung cancer can be taught to residents who work under the supervision of experienced VATS surgeons. Video-assisted thoracic surgery major lung resection for lung cancer should be an integral part of thoracic surgical training program.

Trilogy pericardial valve: hemodynamic performance and calcification in adolescent sheep.
We assessed the hemodynamic performance and calcification potential of a new design of bovine pericardial valve, the Trilogy valve (Arbor Surgical Technologies Inc, Irvine, CA). We compared this new valve with the Perimount valve (Edwards Lifesciences, Irvine, CA) in a randomized prospective study in adolescent sheep. ⋯ These findings demonstrate that a valve designed to reduce stress in the tissue, improve leaflet kinematics, with advanced antimineralization treatment, can exhibit superior calcification resistance in the mitral position of adolescent sheep. The trilobal geometry and independent leaflet suspension design, combined with an advanced tissue treatment, appears to be a promising breakthrough in the effort to develop a more durable and hemodynamically efficient bioprosthetic valve.
