title: Measurement of biventricular septal-to-free wall diameters using sonomicrocrystals.
abstract: An ultrasonic system for the measurement of biventricular septal-to-free wall internal diameters in the dog was described. The ventricular endocardial ultrasonic microcrystals were implanted via the left and right atrial appendages and arranged in a straight line, with minimal invasion of the myocardium and pericardium. Reliable signals were obtained during right ventricular pressure overload and septal myocardial ischemia.
