Fig. 5From: Changes in overall ventricular myocardial architecture in the setting of a porcine animal model of right ventricular dilationSurface plots of helical, intrusion and unit angles in control heart (left) versus heart with pulmonary regurgitation and right ventricular dilation (right). The subdivision of the myocardium into smaller parts is obvious when calculating intrusion angles since this particular angle is highly sensitive to inhomogeneities in the epicardial surfaceBack to article page
