متن کاملExperimental characterization of powered Fontan hemodynamics in an idealized total cavopulmonary connection model
A viscous impeller pump (VIP) based on the Von Karman viscous pump is specifically designed to provide cavopulmonary assist in a univentricular Fontan circulation. The technology will make it possible to biventricularize the univentricular Fontan circulation. Ideally, it will reduce the number of surgeries required for Fontan conversion from three to one early in life, while simultaneously impr...
متن کاملPulmonary vein flow pattern in patients with bidirectional cavopulmonary connection or Fontan circuit
Background Typical flow velocities in the extraparenchymal pulmonary veins demonstrate two major antegrade flow waves: a biphasic systolic wave (S1 and S2) and a monophasic early diastolic wave (D) (Figure 1). There is often flow reversal during atrial systole (a). There is agreement that the forward diastolic pulmonary vein flow wave is caused by left ventricular relaxation and opening of the ...
متن کاملEpics: Operating-system-independent Device/driver Support*
Originally EPICS input/output controllers (IOCs) were only supported on VME-based systems running the vxWorks operating system. Now IOCs are supported on many systems: vxWorks, RTEMS, Solaris, HPUX, Linux, WIN32, and Darwin. A challenge is to provide operatingsystem-independent device and driver support. This paper presents some techniques for providing such support.
متن کاملManagement of the failing Fontan circulation
The ‘Fontan circulation’ has evolved to include a variety of surgical procedures designed to overcome the absence of two distinct ventricular chambers. w1ew3 Inherent to this circulation is chronic elevation of right atrial and vena caval pressure, and absence of a dedicated power source to serve the pulmonary circulation, making low pulmonary vascular resistance and optimal systemic ventricula...
