On the History of Hepatic Vein Catheterization
ABSTRACT Hepatic vein catheterization (HVC) in man was first performed 80 years ago in the wake of right‐sided heart catheterization. Several new methods, recognitions and concepts followed, especially the indirect Fick‐method for determination of splanchnic blood flow. Five years passed before pressure measurements were performed and routine HVCs were

Assessment of Pulmonary Vascular Impedance in Patients With Severe Pulmonary Arterial Hypertension
Pulmonary vascular impedance (PVZ) was calculated from clinical PA pressure and RVOT flow velocity profiles. Participants with increased pulmonary vascular resistance have increased PVZ, afterload, and diastolic stiffness. The characteristic impedance (ZC) to mean PA pressure relationship models the effect of proximal vasculature remodeling on ZC for a

Objective: to study the prognostic value and correlations of hemodynamic parameters during operations under extracorporeal circulation (EC), as well as the possibilities of mathematically predicting the time that takes to recover the normal function of ...

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.

ABSTRACT Background Intensive care following resuscitation from out‐of‐hospital cardiac arrest (OHCA) is based on a set of interventions, all of which are intended to reduce anoxic brain injury and improve outcomes, including sedation, mechanical ventilation, circulatory optimization, and temperature control protocols.

ABSTRACT Background Hemodynamic management after out‐of‐hospital cardiac arrest (OHCA) is critical, yet the impact of vasopressor‐driven mean arterial pressure (MAP) targets on pulmonary circulation and right ventricular (RV) function remains unclear.

Displays bar graphs showing outcome rates stratified by clinical and hemodynamic variables. Asterisks (*) denote statistically significant differences (p ≤ 0.05). “NS” indicates non‐significant comparisons. Percentages are shown above each bar. The top panel corresponds to acute kidney injury (blue bars), and the bottom panel corresponds to acute ...

Minimally Invasive Porcine Model for Chronic Thromboembolic Pulmonary Hypertension
ABSTRACT To elucidate the complex pathophysiology of chronic thromboembolic pulmonary hypertension (CTEPH), a disease associated with bilateral fibrotic obstructions of the pulmonary arteries (PA) and microvascular changes, research relies on animal models, which often depend on invasive techniques, including open surgery.

ABSTRACT Diagnosing pulmonary hypertension (PH) requires invasive right heart catheterization (RHC). However, mean pulmonary artery pressure (mPAP) can be non‐invasively estimated using 4D analysis of cardiovascular magnetic resonance (CMR) flow imaging to assess the duration of pathological vortex flow (Tvortex) in the main pulmonary artery (MPA ...
