How are PV loop used to diagnose HFpEF? Before diving deep into the science, let’s clearly answer the key question: How are PV loop used to diagnose HFpEF? Pressure-volume (PV) loops provide direct, real-time measurements of ventricular pressure and volume, helping clinicians detect abnormal relaxation, increased stiffness, and elevated filling pressures—hallmarks of Heart Failure with … Read more
Introduction to Prosthetic Valve Mismatch Prosthetic heart valves save lives, but they are not without complications. One of the most clinically significant issues is prosthetic valve mismatch, a condition where the effective orifice area of a prosthetic valve is too small relative to the patient’s body size or cardiac demands. Among the most informative ways … Read more
Introduction to VA Coupling in Cardiovascular Physiology VA coupling and strategies to augment contractility or afterload when uncoupled are central concepts in modern cardiovascular physiology and critical care medicine. Ventriculo-arterial (VA) coupling describes the mechanical and energetic relationship between the heart and the arterial system it pumps against. When this relationship is balanced, the heart … Read more
Introduction to Single-Ventricle Congenital Heart Disease Congenital heart disease (CHD) represents the most common form of congenital malformation worldwide. Among its most complex forms are conditions in which only one functional ventricle supports systemic and pulmonary circulation. These patients, often referred to as having single-ventricle physiology, pose some of the most difficult diagnostic and management … Read more
