WebcastsPulmonary artery sealing with ultrasonic energy in open lobectomy: A phase I clinical trial.
Pulmonary artery branch sealing in video-assisted thoracoscopic surgical lobectomy is usually achieved with vascular endostaplers. Iatrogenic pulmonary artery injury may be caused by endostaplers. We evaluated the safety of pulmonary artery sealing with an ultrasonic energy vessel-sealing device in a phase I clinical trial evaluating in vivo safety of the device during open lobectomy. ⋯ Pulmonary artery sealing for vessels with diameter ≤7 mm was safely achieved with an ultrasonic energy vessel-sealing device in open lobectomy. The use of ultrasonic energy vessel-sealing devices in video-assisted thoracoscopic surgical lobectomy may have the advantage of making small, short, pulmonary artery branch sealing safer than with vascular endostaplers. Further studies are necessary before widespread application in lobectomy, including video-assisted thoracoscopic surgical lobectomy.

Comparative StudyComparison of right ventricle-pulmonary artery shunt position in the Single Ventricle Reconstruction trial.
Placement of a right ventricle-pulmonary artery shunt to the left or right of the neoaorta may influence reinterventions, pulmonary artery development, and survival after the Norwood procedure because of differences in shunt and pulmonary artery geometry and blood flow. ⋯ In the Single Ventricle Reconstruction trial, right ventricle-pulmonary artery shunt placement to the right of the neoaorta was associated with fewer shunt revisions and may contribute to improved outcomes in select patients.

Antithrombin III is associated with acute liver failure in patients with end-stage heart failure undergoing mechanical circulatory support.
There are few data on the role of liver dysfunction in patients with end-stage heart failure supported by mechanical circulatory support. The aim of our study was to investigate predictors for acute liver failure in patients with end-stage heart failure undergoing mechanical circulatory support. ⋯ In addition to the Model for End-Stage Liver Disease score, decreased antithrombin III activity tends to be superior in predicting acute liver failure compared with traditionally thought predictors. Antithrombin III measurement may help to identify patients more precisely who are developing acute liver failure during mechanical circulatory support.
