1. Introduction The pressure volume loop in mitral stenosis provides a visual and quantitative understanding of how a narrowed mitral valve affects cardiac dynamics. When systemic afterload rises, the left ventricle faces a double burden: reduced preload due to mitral obstruction and increased pressure to overcome peripheral resistance. This dual challenge leads to diminished stroke … Read more
The pressure-volume (PV) loop is a critical diagnostic tool for understanding cardiac mechanics, offering insights into the dynamic relationship between ventricular pressure and volume during a cardiac cycle. By comparing the mitral stenosis PV loop with that of a normal heart, we can observe profound alterations in the morphology that reflect the underlying pathophysiology. In … Read more
In cardiology, pressure-volume loops are critical tools for understanding the mechanical performance of the heart. These loops illustrate the relationship between left ventricular pressure and volume during a cardiac cycle, offering insights into how the heart fills with blood and pumps it into circulation. In cases of mitral stenosis, a narrowing of the mitral valve, … Read more
