Abstract Aims Veno‐arterial extracorporeal membrane oxygenation (VA‐ECMO) with profound left ventricular (LV) failure is associated with inadequate LV emptying. To unload the LV, VA‐ECMO can be combined with Impella CP (ECMELLA). We hypothesize

This paper presents a mathematical model of the cardiovascular system (CVS) designed to simulate both normal and pathological conditions within the systemic circulation. The model introduces a novel representation of the CVS through a change of coord

Pressure-volume (PV) loop analysis is a sophisticated invasive approach to quantifying load-dependent and independent measures of cardiac function. Biventricular (BV) PV loops allow left and right ventricular function to be quantified simultaneously

Abstract Animal models of cardiovascular disease are often evaluated by invasive instrumentation for phenotyping. As no consensus exists, both open‐ and closed‐chest approaches are used, which might compromise rigour and reproducibility in precli

Abstract Background Left ventricular (LV) contractility and compliance are derived from pressure–volume (PV) loops during dynamic preload reduction, but reliable simultaneous measurements of pressure and volume are challenging with current technolo

A 57-year-old man with end-stage heart failure presented with incessant ventricular tachycardia in the setting of cardiogenic shock, requiring support with a percutaneous left ventricular assist device. He underwent ablation of the ventricular tachyc

Background In patients after heart transplantation, systemic arterial hypertension and enhanced central aortic stiffness contribute to increased ventricular afterload, which might lead to graft dysfunction. The aim of our study was to characterize sy

Cardiac pressure-volume (PV) loop analysis is the reference standard for studying the cardiovascular implications of clinical perturbations (eg, heart failure, aortic occlusion, hypovolemia) and is a benchmark for comparisons with noninvasive alterna
