Understanding the RV Pressure Volume Loop: Complete Guide for Clinicians and Engineers

by

Introduction to RV Pressure Volume Loops The RV pressure volume loop represents a crucial diagnostic and research tool in understanding right ventricular function, especially in patients with pulmonary or congenital heart diseases. Unlike the more commonly discussed left ventricular loop, the right ventricle poses unique anatomical and physiological complexities. Clinicians, biomedical engineers, and researchers rely … Read more

PV Loops Used for Determining Surgical Suitability: Baseline Hemodynamic Profiles in Congenitally Corrected Transposition of the Great Arteries (CCTGA)

by

Introduction Congenitally Corrected Transposition of the Great Arteries (CCTGA) is a rare congenital heart defect characterized by atrioventricular and ventriculoarterial discordance. The right ventricle (RV) assumes systemic circulation, which can lead to progressive dysfunction over time. Surgical intervention may be required, but assessing preoperative risk remains a challenge. Pressure-volume (PV loops) analysis has emerged as … Read more

PV loops in Congenital Heart Disease: Understanding the Left Ventricular Pressure-Volume Relationship

by

In congenital aortic stenosis (AS), the left ventricle faces a significant challenge due to the obstruction caused by a narrowed aortic valve. This condition imposes an increased afterload on the heart, which significantly alters the pressure-volume (PV) loops. These loops are graphical representations that depict the dynamic changes in left ventricular volume and pressure during … Read more
