Several major diseases are associated with alterations of microstructure, for instance hypertrophy, infarction and ischemia. We will describe methods to construct three-dimensional spatial models of cells, cell segments and cell clusters'2,3', which are suitable for computational simulations and quantitative characterization. We will present a novel approach for in vivo imaging of tissue microstructure using catheter-based confocal imaging systems and a method to locally introduce fluorescent dyes3. |
The second part of the talk will cover approaches for computational modeling of function of cardiac cells and tissues. We will present results from our studies on ion channel mutations and their effects on electrophysiology of cardiac cells4, multi-domain modeling of electrical conduction in cardiac tissue5, and cardiac electro-mechanics1. | The second part of the talk will cover approaches for computational modeling of function of cardiac cells and tissues.

We conclude that the presented approaches for imaging and modeling not only provide insights into physiology and structure of normal cells and tissues, but also in their pathophysiology and disease associated structural remodeling. We suggest that these approaches will allow for prediction of courses of diseases and devising therapies for their treatment. | We conclude that the presented approaches for imaging and modeling not only provide insights into physiology and structure of normal cells and tissues, but also in their pathophysiology and disease associated structural remodeling.
