POLYCYTHEMIA, CARDIAC OUTPUT AND CORONARY BLOOD FLOW [PDF]
Pediatric Research, 1977 Decreased cardiac output (CO) and systemic oxygen transport (SOT) in polycythemia (P) are attributed to increased blood viscosity and regarded as potentially harmful. Since P is common in cyanotic heart disease, we studied its effects on CO, SOT and left ventricular coronary blood flow (CBF) and oxygen transport (LVOT) in dogs with acute isovolumlc P ...

Performance evaluation of a pulsatile ventricular assist device under non physiologic pumping frequencies by means FEM and 2D approach [PDF]
, 2017 A ventricular assist device (VAD) is a blood pump that works in parallel with heart. It is used as a mechanical assistance for patients that suffer cardiac insufficiency: as a therapy, as a bridge to transplant or to extend life.

Including Aortic Valve Morphology in Computational Fluid Dynamics Simulations: Initial Findings and Application to Aortic Coarctation [PDF]
, 2012 Computational fluid dynamics (CFD) simulations quantifying thoracic aortic flow patterns have not included disturbances from the aortic valve (AoV). 80% of patients with aortic coarctation (CoA) have a bicuspid aortic valve (BAV) which may cause adverse ...

The Flow of Blood Supplying the Cardiac Atria
Experimental Biology and Medicine, 1946 SummaryThe flow of blood into the left anterior auricular artery was measured phasically and quantitatively in the heart-lung preparation. The curves indicate that forward flow into the auricular artery occurs during ventricular systole and diastole, with abrupt, momentary interruptions of inflow at the onset of ventricular systole and diastole ...
