Randomized Controlled Trial Multicenter Study Comparative Study
Impact of Heparin- or Nonheparin-Coated Circuits on Platelet Function in Pediatric Cardiac Surgery.
Extracorporeal circuit coating has been shown to improve coagulation derangements during pediatric cardiopulmonary bypass (CPB). This study compared platelet function and hemostasis activation in pediatric cardiac surgery conducted with nonheparin coating (Balance; Medtronic, Minneapolis, MN) versus heparin-based coating (Carmeda; Medtronic) circuits. ⋯ The two circuits showed similar biological effects on platelet function and coagulation. This observation may be useful in optimizing the conduct of CPB and in rationalizing its cost for the treatment of congenital heart disease.

Case Reports
Minimally Invasive Awake Mitral Valve Surgery and Cardiopulmonary Bypass Without General Anesthesia.
Herein, we report the case of a 49-year-old man with a potentially fatal allergy to propofol and remifentanil who underwent awake minimally invasive mitral valve surgery with cardiopulmonary bypass using thoracic epidural anesthesia, without the need for endotracheal general anesthesia. The aim was the management of spontaneous respiration during cardiopulmonary bypass surgery in an awake patient.

Comparative Study
Long-Term Impact of Cytomegalovirus Serologic Status on Lung Transplantation in the United States.
Cytomegalovirus (CMV) infection has been associated with poor outcomes after solid organ transplantation. The long-term impact of donor and recipient CMV serological status on lung transplant outcomes remains unclear. Accordingly, we evaluated the impact of donor and recipient CMV status on long-term patients as well as allograft survival after single (SLT) and double lung transplantation (BLT). ⋯ CMV seronegative recipients undergoing either BLT or SLT from CMV seropositive donors have the highest risk of long-term mortality that extends beyond the first year. Further studies are needed to determine the causes of higher mortality observed in the CMV seronegative recipients and risks and benefits of extension of CMV prophylaxis, particularly in the high-risk group.

Comparative Study
Comparison Between Esophagectomy and Definitive Chemoradiotherapy in Patients With Esophageal Cancer.
This study compared survival between definitive chemoradiotherapy (CRT) and esophagectomy alone among patients with locoregional esophageal squamous cell carcinoma (SCC). ⋯ Esophagectomy alone could provide better survival than definitive CRT for patients with clinical stage I/II esophageal SCC. However, definitive CRT and esophagectomy yield similar overall survival rates in clinical stage III patients.

Over the last decade, aortic valve replacement with rapid-deployment biologic bioprostheses has become a common alternative to the use of mechanical or biologic stented valves for high-risk patients. A 63-year-old patient underwent uncomplicated valve replacement with the Edwards Intuity valve (Edwards Lifesciences, Irvine, CA). ⋯ Both valves were replaced by a conventional stented bioprosthesis. This case report describes the first case of valve migration for the Edwards Intuity Elite rapid-deployment aortic valve and discusses possible explanations.
