The effect of myocardial anisotropy on volume measurement using conductance catheter techniques in the right ventricle

Chanchai Thaijiam, Timothy John Gale

Abstract


The effect of myocardial anisotropy on ventricular volume measurements, taken using conductance catheter techniques in the right ventricle, is investigated using finite element models of the isolated heart. The governing equation is Poisson's equation. Model results show calculated volumes are more accurate if anisotropy is included in the model, due to increased confinement of current within the ventricle. This can lead to more accurate blood volume measurements in the right ventricle.
