Surgeon and center volume influence on outcomes after arterial switch operation: analysis of the STS Congenital Heart Surgery Database.
The relative impact of center volume and of surgeon volume on early outcomes after the arterial switch operation (ASO) is incompletely understood. ⋯ Center and surgeon volume each influence early outcomes after ASO; however, surgeon volume appears to play a more prominent role. Surgeon and center ASO volume should be considered in the context of initiatives to improve outcomes from ASO for transposition of the great arteries.

Significant aortic regurgitation (AR) after continuous-flow left ventricular assist device (cf-LVAD) placement affects device performance and patient outcomes. This study examined the development of AR and long-term results after implantation of cf-LVADs. ⋯ AR is associated with longer cf-LVAD support duration and persistent aortic valve closure. Incidence of moderate or greater AR after cf-LVAD implantation increases significantly after 3 years. The clinical implications of these data may warrant consideration of prophylactic aortic valve replacement at the time of cf-LVAD implantation, particularly with expected longer duration of support and in patients with preexisting AR that is more than mild.

Impact of preoperative location on outcomes in congenital heart surgery.
Little is known about the impact of preoperative location on outcomes in infants undergoing cardiac surgery for congenital heart disease. This study was designed to evaluate the morbidity and mortality among infants who were cared for in a neonatal ICU (NICU) versus dedicated cardiovascular intensive care unit (CVICU) prior to cardiac surgery in a multi-institutional population. ⋯ This study demonstrates that preoperative location might impact outcomes in children undergoing operation for congenital heart disease. It is possible that preoperative location may be surrogate for other factors that may bias the results. Further study is warranted.

Comparative Study
Perioperative blood product use: a comparison between HeartWare and HeartMate II devices.
The HeartWare (HW) (Framingham, MA) and the HeartMate II (HM II) (Thoratec Inc, Pleasanton, CA) continuous-flow left ventricular assist devices (CF-LVADs) are commonly used to bridge patients to transplantation. We hypothesized that there are differences in perioperative blood product (BP) use and chest tube (CT) output between CF-LVAD types. ⋯ Compared with HM II, implantation of the HW CF-LVAD was associated with reduced intraoperative and postoperative BP use and decreased CT output. Increased awareness of device-related differences in bleeding and BP use may improve CF-LVAD patient outcomes.

Lung volume reduction with valves is increasingly used to treat selected patients with severe emphysema. The indications for this procedure have been previously described; however, its contraindications have not yet been conclusively established. This case highlights the potentially severe complications of endobronchial one-way valve placement in the setting of a previous pleurodesis.
