Fig. 1From: Sildenafil treatment attenuates ventricular remodeling in an experimental model of aortic regurgitationAortic regurgitation. Left panel shows left ventricle (LV) from a rat with aortic regurgitation with regurgitation indicated by arrows. Right panel shows pressure volume loops from a sham-operated (left) and untreated (AR) rat (right). The horizontal axis indicate relative volume unit (RVU) and the vertical axis indicate intraventricular pressureBack to article page
