Patrick Sullivan Aortic regurgitation is a condition where the aortic valve fails to close completely during diastole, allowing blood to flow back into the left ventricle (LV) from the aorta. This backward flow creates unique challenges for the cardiovascular system, particularly concerning hemodynamics—the study of blood flow. One of the most insightful tools for understanding these hemodynamic … Read more
Introduction Pressure-volume (PV) loops have become an essential tool in cardiovascular research and clinical trials. These sophisticated graphical representations of the relationship between pressure and volume in the heart during a cardiac cycle offer deep insights into the mechanics of heart function. Researchers and clinicians have leveraged PV loops to advance the understanding of heart … Read more
The circulatory system is an intricate network where the heart and blood vessels work together to maintain the body’s blood flow. Central to this system is the pressure-volume relationship in blood vessels, a critical factor in determining vascular health and understanding various cardiovascular diseases. The elasticity, or stiffness, of arteries plays a significant role in … Read more
Introduction The human heart is a marvel of biological engineering, tirelessly working to pump blood throughout the body. One of the most insightful ways to understand and evaluate cardiac function is through the use of Pressure-Volume (PV) loops. These loops offer a visual representation of the relationship between the pressure inside the heart’s chambers and … Read more
