Larger pulmonary artery to ascending aorta ratios are associated with decreased survival of patients undergoing pulmonary endarterectomyCentral MessagePerspective

JTCVS Open, 2022
Objectives: The ratio of pulmonary artery (PA) and ascending aorta (AA) diameters has recently been shown to be a useful indicator for disease severity and predictor of outcome in patients with pulmonary hypertension and heart failure.

Myocardial oxygen consumption, myocardial efficiency, and mechanical efficiency: A review across pathologic and physiologic states

Physiological Reports, Volume 14, Issue 10, May 2026.
Abstract Myocardial work and oxygen consumption (MVO2) are tightly coupled. The patient's physiological state, presence of disease, heart rate, and microvascular control of oxygen delivery all combine to maintain this relationship. The myocardial efficiency (MyoEff) of the heart is determined by the ratio of stroke‐work (SW) divided by MVO2, whereas ...

Cardiac power output accurately reflects external cardiac work over a wide range of inotropic states in pigs [PDF]

, 2019
BACKGROUND: Cardiac power output (CPO), derived from the product of cardiac output and mean aortic pressure, is an important yet underexploited parameter for hemodynamic monitoring of critically ill patients in the intensive-care unit (ICU).

Verification of a Fluid–Structure Interaction Model for Aortic Stenosis Through Comparison With In Vitro Experiments

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.
A patient‐specific Fluid–structure Interaction (FSI) model of aortic stenosis was verified against in vitro experiments using a mock‐loop circulatory system with patient‐specific calcified and non‐calcified valve models under varying flow conditions. The in vitro experiments were replicated in the FSI model.
