Acute functional consequences of left ventriculotomy Louis R DiBernardo, MD, Paul M Kirshbom, MD, Lynne A Skaryak, MD, Renee L Quarterman, MD, Ronald L Johnson, Mark J Davies, J.William Gaynor, MD, Ross M Ungerleider, MD The Annals of Thoracic Surgery Volume 66, Issue 1, Pages 159-165 (July 1998) DOI: 10.1016/S0003-4975(98)00376-2

Fig 1 Preload recruitable stroke work (PRSW) is the global stroke work–end-diastolic volume relation. A representative linear relationship obtained during the course of a single vena caval occlusion is shown. The equation of the regression line is presented. (Lw = x-intercept; Mw = slope of the stroke work–end-diastolic volume relation; R2 = correlation coefficient of the line.) The Annals of Thoracic Surgery 1998 66, 159-165DOI: (10.1016/S0003-4975(98)00376-2)

Fig 2 Intrinsic myocardial function relationship. A representative linear relationship between myocardial power output (a derivation of unit myocardial power based on stress-strain relations) and end-diastolic circumferential strain is shown. Data were obtained during a single vena caval occlusion. (Lmp = x-intercept; Mmp = slope of the relationship; MPO = myocardial power output; R2 = correlation coefficient of the line.) The Annals of Thoracic Surgery 1998 66, 159-165DOI: (10.1016/S0003-4975(98)00376-2)
