Inflow Valve Regurgitation During Left Ventricular Assist Device Support May Interfere With Reverse Ventricular Remodeling Nader Moazami, Michael Argenziano, Takushi Kohomoto, Shahram Yazdani, Eric A Rose, Daniel Burkhoff, Mehmet C Oz The Annals of Thoracic Surgery Volume 65, Issue 3, Pages 628-631 (March 1998) DOI: 10.1016/S0003-4975(97)01294-0

Fig. 1 Experimental setup for determination of end-diastolic pressure–volume relation. A balloon placed inside the left ventricle is inflated at 25-mL increments and pressure is recorded simultaneously. The remnants of the aortic root are cross-clamped. This setup offers an accurate means of controlling preload and afterload in an ex vivo system. The Annals of Thoracic Surgery 1998 65, 628-631DOI: (10.1016/S0003-4975(97)01294-0)

Fig. 2 End-diastolic pressure–volume relationship determined at time of cardiac transplantation. Values are reported as mean ± standard deviation. (DCM = dilated cardiomyopathy; IR = inflow regurgitation; LVAD = left ventricular assist device; NL = normal.) The Annals of Thoracic Surgery 1998 65, 628-631DOI: (10.1016/S0003-4975(97)01294-0)
