... Heartmate II is an implantable, axial-flow Left Ventricular Assist Device capable of providing a cardiac output up to 10 l/min. Blood is directed from a cannula in the left ventricular apex to an impeller and then to the ascending aorta (Figure 1). The flow of the device is non-pulsatile and is typically adjusted to allow the aortic valve open intermittently [6]. ...

A new decay detection system with high detection efficiency and low detection threshold has been developed for charged-particle decay studies, including -delayed proton, decay or direct proton emission from proton-rich nuclei. The detection system was tested by using the -delayed proton emitter 24Si and was commissioned in the decay study of 22Si p...
Background: The atrial high-rate episodes (AHREs) are considered clinically correlated with atrial fibrillation (AF). Moreover, the stroke risk is increasing following the AHREs burden and/or CHA 2 DS 2-VASc score. However, the predisposing factors of the AHREs were not clearly known.
Objective: To investigate the predisposing factors of AHREs in...

We report the successful use of peripheral nerve blocks for provision of surgical anesthesia for knee surgery in a patient who had end-stage heart failure, who was supported by a HeartMate II left ventricular assist device, and who was anticoagulated. We discuss the anesthetic implications involved in the care of patients being anticoagulated and on left ventricular assist device.
A 38-year-old female, G2P0010, 12 weeks pregnant, presents with an open right radial fracture after falling on a muddy sidewalk. She has a history of left lower extremity deep venous thrombosis (DVT) after taking oral contraceptives. Because of this, she was placed on subcutaneous enoxaparin sodium (a low molecular weight heparin), which she has injected every 12 h for the last 3 months. She took her last dose 5 h prior to her arrival at the hospital and reported her last meal as 6 h before her admission. She received morphine in the emergency room to alleviate her pain.
