Introduction to Cardiac Mechanics Understanding how the heart functions goes beyond just knowing that it pumps blood. At its core, cardiac mechanics provides a detailed explanation of how the heart generates pressure, moves volumes of blood, and responds to physiological demands. Among the many tools used to evaluate cardiac function, the PV loop and Frank … Read more
Introduction to Myocardial Work and Cardiac Reserve The heart is an incredible muscle—relentlessly beating to pump blood and meet the body’s demands. But what happens when those demands increase? Whether you’re exercising, climbing stairs, or under physiological stress, your heart must rise to the occasion. This capacity is known as cardiac reserve, and it’s closely … Read more
Introduction to Real-Time PV Loop Monitoring In the evolving landscape of cardiac surgery, patient safety and outcome optimization are paramount. One of the most innovative tools supporting these goals is real-time PV loop monitoring. This advanced technique provides clinicians with a dynamic view of the heart’s mechanical function, allowing them to assess how well it … Read more
The RV PV loop is a powerful graphical representation that describes the pressure-volume relationship of the right ventricle. As a fundamental model, it plays a key role in understanding right ventricular mechanics. Unlike its left-sided counterpart, the right ventricle exhibits unique structural, functional, and hemodynamic features, making this loop crucial for both clinical assessment and … Read more
Introduction The assessment of intraventricular dyssynchrony is crucial in diagnosing and managing heart failure and other cardiac dysfunctions. Among the various measurement techniques, conductance catheterization has emerged as a powerful tool for real-time, high-fidelity intracardiac volume assessment. This article explores the fundamental principles and methodologies behind conductance catheter measures of intraventricular dyssynchrony, setting the foundation … Read more
