title = "Semi-automated assessment of left ventricular performance from on-line pressure-area relations",
abstract = "A new method of assessing ventricular function was developed which utilizes left ventricular (LV) cross-sectional area as an index of ventricular volume. Echocardiographic automated border detection can measure LV cavity area and be combined with pressure to display pressure-area loops in real time. This methodology was applied to an open-chest dog model during inotropic modulation to test its feasibility to assess LV performance. Preload was varied by apneic inferior vena caval (IVC) occlusions before and after administration of dibutamine and propranolol as positive and negative inotropes, respectively. From these pressure-area loops, various indices describing ventricular contractile stat and pump performance were derived, including : end-systolic pressure area relationship, maximal elastance, and preload recruitable stroke force.",
