While β-blockers can be effective in controlling tachyarrhythmias after pediatric cardiac surgery, a negative inotropic influence sometimes complicates their use. Landiolol hydrochloride is a novel, ultra-short-acting β-blocker recently developed in Japan. The drug has higher β1:β2 selectivity ratio and a less negative inotropic effect. This study retrospectively evaluates the efficacy and safety of landiolol in the management of tachyarrhythmias after pediatric cardiac surgery. ⋯ Landiolol was efficacious in treating tachyarrhythmia in pediatric cardiac surgery. The desired negative chronotropic effect was achieved without significant hemodynamic compromise. The ultra-short half-life of landiolol provided rapid dose manipulation. This study suggests that landiolol is a promising option for the management of postoperative tachyarrhythmias in pediatric patients.

Case Reports
Pulmonary resection of lung cancer in a patient with partial anomalous pulmonary venous connection.
We report a case of a 64-year-old man in whom a partial anomalous pulmonary venous connection (PAPVC) was found before right lower lobectomy for lung cancer. In addition to lung cancer, there was a right superior pulmonary vein that drained into the superior vena cava (SVC). ⋯ Therefore cardiac catheterization was performed to calculate the pulmonary-to-systemic flow rate in the presence of blocked blood flow to the lower lobe pulmonary artery. As a result, we successfully performed lobectomy without correcting the PAPVC.

Coagulopathy is a common complication after ascending and transverse arch aortic surgery with profound hypothermic circuit arrest (PHCA). Blood conservation strategies to reduce transfusion have been ongoing and involve multiple treatment modalities in modern cardiac surgery. The purpose of this study is to evaluate the effectiveness of autologous platelet-rich plasma (aPRP) as a blood conservation technique to reduce blood transfusion in ascending and arch aortic surgery. ⋯ The utilization of aPRP was associated with a reduction in allogeneic blood transfusions as well as a decrease in early postoperative morbidity during repairs of the ascending and transverse arch aorta using PHCA.

Comparative Study
Delayed management of blunt traumatic aortic injury: open surgical versus endovascular repair.
A growing body of evidence has shown that delayed management of traumatic injury of the thoracic aorta determines survival benefits as compared with immediate treatment. However, few data exist comparing outcomes after delayed open surgical or endovascular management. Accordingly, we reviewed our experience with delayed management, stratifying the data according to type of repair; open surgical versus endovascular. ⋯ Delayed management of traumatic aortic injury was associated with satisfactory short- and long-term results without significant differences between open surgical and endovascular repair. However, the reduced invasiveness of endovascular repair can optimize operative timing allowing prompt aortic repair in unstable patients, earlier repair in stable patients, and, when indicated, easier concomitant non-aortic surgery.

The role of surgical resection for stage IIIA non-small cell lung cancer (NSCLC) is unclear. We sought to examine outcomes after pneumonectomy for patients with stage IIIA disease. ⋯ Long-term survival after pneumonectomy for stage IIIA NSCLC is within an acceptable range, but pneumonectomy may not be appropriate after induction therapy or in patients with renal insufficiency. Patient selection and operative technique that limit perioperative morbidity and facilitate the use of adjuvant chemotherapy are critical to optimizing outcomes.
