title: Accuracy of ventricular lumen volume measurement by intraventricular balloon method.
abstract: To assess the accuracy of left ventricular volume measured by the intraventricular balloon method, we measured the space between the endocardium and the gradually inflated balloon in six Formalin-fixed canine left ventricles. The space was as small as 1-1.5 ml for intraballoon pressure of 100-200 mmHg and tended to increase to 2 ml with decreases in pressure to 50 mmHg.
