Abstract

The mechanism by which the heart fills with blood (diastolic function) has remained a topic of permanent controversy since William Harvey (1628) characterized the circulatory system. Because technology (echocardiography, MRI, CT, electronic catheters) allows superb data acquisition of anatomy, structure, motion and hemodynamics – new insights into filling can be achieved by application of engineering principles (Newton’s laws, volume conservation, incompressibility, causality, …). I will describe selected aspects of how the heart works from the perspective of a cardiologist/physiologist – and then show that by invoking basic engineering and physical principles, selected aspects of diastolic function become apparent. The ability of kinematic modeling to explain previously observed – but heretofore unexplained – physiology, and even to predict ‘new’ physiology will be included. Some clinical examples will highlight its translational potential in the real world of cardiology.
