Afterload independent, inotropic state sensitive indices of regional function were sought in 31 canine hearts instrumented with piezoelectric crystals to depict trapezoidal areas in the left anterior descending and circumflex arterial beds. Control and postinterventional end-systolic pressure versus regional length and area relationships and regional stroke work versus end-diastolic length and area relationships were inscribed during incremental volume loading on right heart bypass. Hearts were… CONTINUE READING
