Introduction The heart is a highly efficient mechanical pump, continuously adjusting to changes in vascular conditions to maintain optimal cardiac output. A critical tool for analyzing cardiac function is the pressure-volume (PV) loop, which provides real-time insight into how the heart adapts to various physiological and pathological conditions. Among the many factors influencing cardiac performance, … Read more
Introduction Catheter ablation is a widely used intervention for treating cardiac arrhythmias, particularly atrial fibrillation (AF) and ventricular tachycardia. This procedure directly alters myocardial tissue properties, impacting cardiac function and hemodynamics. One of the key methods to assess these changes is through pressure-volume (PV) loop hemodynamic in electrophysiology, which provides real-time insight into cardiac performance. … Read more
Introduction Echocardiography has long been a cornerstone of cardiovascular imaging, offering non-invasive insights into heart function. However, when it comes to pressure-volume (PV) loop analysis, echocardiographic data acquisition presents several technical challenges. While PV loops provide crucial information about cardiac mechanics, accurately capturing this data via echocardiography is complex due to imaging limitations, hemodynamic variability, … Read more
Introduction Heart failure is a complex clinical syndrome characterized by the heart’s inability to pump blood efficiently. It is broadly classified into two types: heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). A valuable diagnostic tool for differentiating these conditions is pressure-volume (PV) loop analysis, which provides insight … Read more
Understanding cardiac mechanics is pivotal in advancing diagnostic, therapeutic, and research methodologies for cardiovascular diseases. One of the most comprehensive ways to study the intricate workings of the heart is through pressure-volume (PV) loops, which illustrate the relationship between pressure and volume in the cardiac cycle. The advent of high-fidelity hemodynamics and computational modeling has … Read more
Afterload plays a crucial role in cardiovascular physiology, influencing how the heart functions under varying conditions. The pressure-volume (PV) loops provide a visual representation of cardiac dynamics, where afterload is a key determinant shaping the loop’s position and size. Understanding this relationship is vital for healthcare professionals, students, and researchers in the medical field. What … Read more
Introduction The heart is a complex, efficient pump that performs the vital task of circulating blood throughout the body. Its performance can be assessed using Pressure-Volume (PV) loops, which graphically represent the changes in pressure and volume within the left ventricle during a cardiac cycle. These loops provide a wealth of information about cardiac function, … Read more
The Fontan circulation represents a pivotal approach for managing single-ventricle physiology in congenital heart disease patients. However, the unique physiology of the Fontan system—characterized by the absence of a sub-pulmonary ventricle—has profound implications for cardiovascular dynamics. Pressure-volume (PV) loops provide a robust framework to analyze these hemodynamic alterations, offering insights into how preload, afterload, and … Read more
Understanding the diastolic function of the right ventricle (RV) is crucial in diagnosing and managing various cardiovascular diseases. This article delves into the relaxation and compliance properties of the RV, with an emphasis on the depiction of these properties in Right Ventricle PV Loop filling phases. By understanding the nuances of pressure-volume (PV) loops, clinicians … Read more
