This study derives a one-dimensional model of coronary flow accounting for vessel taper and boundary slip, suggesting a new approach for assessing ischaemic heart disease.
Key Points
The novel one-dimensional model significantly correlates with established coronary flow assessments, showing strong predictive capability.
Analyzing 15 idealized anatomical cases revealed that anatomical parameters impact virtual fractional flow reserve and absolute coronary flow metrics.
The sensitivity analysis underscores the role of side branch flow and vessel characteristics over traditional stenosis parameters, prompting a reevaluation in diagnostic practices.
This mathematically consistent approach offers modest differences compared to existing models while enhancing coronary physiology accuracy.
