As the left ventricle dilates during chronic volume overloading, it assumes a more spherical configuration, suggesting a nonuniform regional myocardial response. Accordingly, we studied early alterations in left ventricular geometry and regional function induced by chronic volume overloading in the canine heart subjected to an aortocaval fistula. Nine mongrel dogs were instrumented with ultraso...
