Multicenter Study
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.

Comparative Study Clinical Trial
Preoperative assessment of chest wall invasion in non-small cell lung cancer using surgeon-performed ultrasound.
Chest wall invasion in operable lung cancer upgrades the stage and can affect operative planning. Diagnosing chest wall invasion preoperatively is important in patient consent, in the choice of operative incision placement, and can be helpful in choosing an operative approach (open vs thoracoscopic). The objectives of this study were to determine the diagnostic accuracy of preoperative, surgeon-performed ultrasound (US) in assessing tumoral chest wall invasion (T3) in non-small cell lung cancer (NSCLC) patients and to compare its accuracy vs preoperative computed tomography (CT). ⋯ Surgeon-performed preoperative chest wall US can reliably diagnose tumoral chest wall invasion in patients with NSCLC. CT scan has poor sensitivity in predicting chest wall invasion preoperatively. Surgeon-performed US can be considered as a complementary adjunct to preoperative imaging in patients with pulmonary lesions abutting the chest wall to improve preoperative diagnosis, staging, and operative planning.

Continued donor organ shortage and improved outcomes with current left ventricular assist device (LVAD) technology have increased the number of patients supported with bridge-to-transplantation (BTT) therapy. Using the United Network of Organ Sharing (UNOS) database, we assessed the impact on survival in patients supported with BTT while on the heart transplant waiting list. ⋯ Patients supported with an HM II LVAD as BTT therapy were older with increased comorbidities; they demonstrated an improved survival while listed for heart transplantation. The use of LVADs as a BTT strategy can potentially improve patient survival while waiting for transplantation and allow better allocation of donor hearts.

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.

Comparative Study
Endobronchial ultrasonography versus mediastinoscopy: a single-institution cost analysis and waste comparison.
Mediastinoscopy (MED) and endobronchial ultrasonography with transbronchial needle aspiration (EBUS-TBNA) have similar accuracy for mediastinal lymph node sampling (MLNS). The threatened financial and environmental sustainability of our health care system mandate that surgeons consider cost and environmental impact in clinical decision making of similarly effective procedures. We performed a cost and waste comparison of MED versus EBUS-TBNA for MLNS to raise awareness of the financial and environmental implications of our practices. ⋯ MED costs less than EBUS-TBNA in the OR setting but generates 3.6 times the amount of EBUS-TBNA waste. The cost of EBUS-TBNA may improve by performance in the endoscopy suite, and surgical pack revision could reduce the amount of MED solid waste. This comparison sets the stage for sophistication of our clinical decision making, taking into consideration the major threats to our health care system.
