Pump thrombus is dreaded complication of CF LVAD technology [1] that can require repeat surgery to replace the pump or lead to death. [2] In suspected pump thrombus, the clinical patient condition or pump parameters suggest thrombus on any of the blood-contacting surfaces of the pump (inflow cannula, pump itself, or outflow graft).
The first left ventricular assist device (LVAD) system was created by Domingo Liotta at Baylor College of Medicine in Houston in 1962. The first LVAD was implanted in 1963 by Liotta and E. Stanley Crawford. The first successful implantation of an LVAD was completed in 1966 by Liotta along with Dr. Michael E. DeBakey.
LVAD may stand for: Left ventricular assist device, see Ventricular assist device; Low-Velocity Airdrop, see HALO/HAHO This page was last edited on 28 ...
Berlin Heart manufactures two types of VADs: implantable and paracorporeal. INCOR is an axial-flow pump for support of the left ventricle.In this system, the pump is implanted directly next to the heart and is connected to the heart by cannula.
Increased left ventricular hypertrophy with increased EDV and SV is seen with athletes [1] and in healthy normal elderly individuals. [2] Moderate hypertrophy allows for a lower heart rate, increased diastolic volume, and thus higher stroke volume.
At this stage the majority of the flow can be described with velocity vectors normal to the entrance, but in plane velocities tangent to the flow are present. [3] As the path starts to curve in the ascending aorta, the blood towards the outside of the arch tends to rotate towards the inner wall, causing a helical pattern that is observed in ...
This normal ventricular impulse is often an average of a multiple of normal beats of the patient acquired in the recent past and known as a template. The integration of these various parameters is very complex, and clinically, the occurrence of inappropriate therapy is still occasionally seen and a challenge for future software advancements.
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
