Tracking the right ventricle work in progress.

d i ( i a f r i v g ( Unraveling the mysteries of cardiac contraction has been a major preoccupation of the cardiac investigators. More recently, the right ventricle is in focus, especially the right ventricle in the systemic position. The differences between the right and the left ventricles in myocardial architecture, blood supply, metabolism, response to loading conditions, and embryological origin have been well documented (1). However, why the right ventricle in systemic position is compatible with long life only in some
