Measurement of cardiac index by transpulmonary thermodilution using an implanted central venous access port: a prospective study in patients scheduled for oncologic high-risk surgery. [PDF]

PLoS ONE, 2014
BACKGROUND:Transpulmonary thermodilution allows the measurement of cardiac index for high risk surgical patients. Oncologic patients often have a central venous access (port-a-catheter) for chronic treatment.

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.

Therapeutic Galectin‐3 Apheresis Improves Sepsis Outcomes Through Coordinated Neutrophil Modulation and Endothelial Barrier Preservation: A Translational Study

MedComm, Volume 7, Issue 4, April 2026.
Gal‐3 apheresis reduces neutrophil hyperactivation (CXCL2/CXCL8, MPO, NETs), preserves endothelial barrier function (tight junctions, vWF/VCAM‐1/ICAM‐1), and attenuates PI3K/AKT/HIF‐1α signaling. These coordinated effects significantly improve hemodynamics, reduce pulmonary edema (ELWI), lower vasopressor and fluid requirements, and increase survival ...

Post lung-transplant predictive value of thermodilution vs estimated Fick cardiac output measurement

JHLT Open
Background: Comparison of thermodilution (TD) and indirect Fick (iFick) methods of cardiac output (CO) measurement has not been well described in patients with World Health Organization (WHO) group 3 pulmonary hypertension (PH).

Male Sex Is Associated With Severe Pulmonary Hypertension and Worse Outcome in Chronic Obstructive Pulmonary Disease Patients Referred for Right Heart Catheterization

Pulmonary Circulation, Volume 16, Issue 2, June 2026.
ABSTRACT Sex differences in COPD patients with concomitant pulmonary hypertension remain unexplored. Analyzing 171 patients from the GRAPHIC registry in Graz, Austria, we found that male sex was independently associated with increased mortality risk, despite comparable comorbidities and airflow obstruction, which may be explained by the increased rate ...

Correction of Hemodynamic Disorders in the Complex Surgical Correction of Acquired Cardiac Valvular Defects

Общая реаниматология, 2011
Objective: to compare the efficiency of using the values of transpulmonary (PiCCO) and prepulmonary (Swan-Ganz catheter) thermodilution as guides to targeted therapy for hemodynamic disorders in the surgical correction of mixed cardiac valvular defects ...

Chronic Thromboembolic Pulmonary Disease Phenotypes Using Upright Invasive Cardiopulmonary Exercise Testing

Pulmonary Circulation, Volume 16, Issue 2, June 2026.
ABSTRACT Patients with chronic thromboembolic pulmonary disease (CTEPD) without resting pulmonary hypertension (PH) frequently experience dyspnea which is not explained by stationary assessment and therefore requires cardiopulmonary exercise testing for further diagnostic insight.

Aortic volume determines global end-diastolic volume measured by transpulmonary thermodilution

Intensive Care Medicine Experimental, 2020
Background Global end-diastolic volume (GEDV) measured by transpulmonary thermodilution is regarded as indicator of cardiac preload. A bolus of cold saline injected in a central vein travels through the heart and lung, but also the aorta until detection ...

Stima della portata della fistola artero-venosa mediante termodiluizione nei pazienti in emodialisi cronica: esperienza monocentrica.

Giornale di Clinica Nefrologia e Dialisi, 2020
Purpose: Vascular access surveillance in hemodialysis is today an important challenge for nephrologist.  Low blood flow is a risk factor for development of thrombosis of native fistula or graft.

Feasibility and Improved Diagnostic Yield of Intracoronary Adenosine to Assess Microvascular Dysfunction With Bolus Thermodilution

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Bolus thermodilution and intravenous adenosine are established methods for coronary microcirculatory assessment. Yet, its adoption remains low, partly due to procedural time and patient discomfort associated with intravenous adenosine.
