Numerical simulation of the blood flow through the coronary artery stenosis: Effects of varying eccentricity

Mariia Timofeeva et al.

Summary: Stenoses in coronary arteries are often asymmetric, which has significant effects on blood flow behavior downstream of the stenosis. Eccentricity causes the flow to deflect away from the model's centerline, leading to the development of secondary flow. The consideration of both the degree of eccentricity and the degree of stenosis could improve patient stratification.

Haemodynamic performance of 16-20-mm extracardiac Goretex conduits in adolescent Fontan patients at rest and during simulated exercise

Friso M. Rijnberg et al.

Summary: This study investigated the relationship between conduit size and haemodynamics in adolescent Fontan patients. The results showed that most patients had relatively undersized conduits, leading to suboptimal haemodynamics.

The Influence of Respiration on Blood Flow in the Fontan Circulation Insights for Imaging-Based Clinical Evaluation of the Total Cavopulmonary Connection

Seline F. S. van der Woude et al.

Summary: Congenital heart disease is the most common type of birth defect, with functionally univentricular heart defects being the most severe form. The Fontan circulation offers a unique solution for single ventricle patients, relying on increased systemic venous pressure to drive blood towards the lungs.

Estimation of pulsatile energy dissipation in intersecting pipe junctions using inflow pulsatility indices

Reza Rasooli et al.

Summary: This study characterizes the effect of inflow pulsatility on hydrodynamic power loss inside intersecting DIPI with cross-flow mixing using CFD simulations. Three easy-to-calculate pulsatility indices were proposed to predict pulsatile flow performance, and results showed strong correlations between inflow pulsatility, total inflow pulsatility, inflow frequency content, and power loss. The analytical expression provided by the study can predict pulsatile power loss inside DIPI geometry with high accuracy and is a valuable predictive tool for estimating energy dissipation in complex junctions with minimal CFD computations.

The Influence of Respiration on Blood Flow in the Fontan Circulation: Insights for Imaging-Based Clinical Evaluation of the Total Cavopulmonary Connection

Seline F. S. van der Woude et al.

Summary: Congenital heart disease is a common birth defect, with univentricular heart defects being the most severe. The Fontan circulation is a unique solution for single ventricle patients. Recent studies show that while respiration influences pulsatility in blood flow, it has limited effect on net forward flow in the Fontan circulation.
