[Effect of calcium-free perfusion on the myocardium]

Authors studied the effect of the perfusion free of calcium on the myocardium. It was performed on the Langendorff cannula. Ultrastructural alterations were described in detail. The severity of the damage to the cells could be correlated with the duration of the perfusion. This study suggests that in the pathogenesis of these lesions lack of the membrane stabilizing effect of calcium ions may play a role.
