Impact of Higher Versus Lower Blood Pressure Targets on Pulmonary Vascular Hemodynamics During Intensive Care After Out‐of‐Hospital Cardiac Arrest

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
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.

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.

Comparison of Intraoperative Doppler Flow Measurements and Algorithmic Flow Estimations in Patients Undergoing Durable Left Ventricular Assist Device Implantation

Artificial Organs, Volume 50, Issue 8, Page 1164-1169, August 2026.
Direct intraoperative HeartMate 3 LVAD flow measurements using an ultrasonic probe revealed consistently higher values by approximately 0.5 L/min compared to device‐estimated flows. This discrepancy remained stable across pump speed settings, highlighting the importance of distinguishing measured from estimated flow in HeartMate 3 patients.

Morphological changes in the arterial pressure waveform following hemodynamic therapies in critical care: A clinical proof‐of‐concept study in older adults

Physiological Reports, Volume 14, Issue 15, August 2026.
In 132 cardiac surgery patients, fluid bolus, norepinephrine, and dobutamine each produced a distinct, recognizable pattern in arterial waveform morphology (systolic area/downstroke time, diastolic area/time, augmented pressure), suggesting arterial waveform analysis is a promising tool for bedside hemodynamic decision support.

Clinical and Physiological Predictors of Acetylcholine‐Induced Coronary Spasm in ANOCA/INOCA Patients: A Retrospective Cohort Study

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 14-20, July 1, 2026.
ABSTRACT Background A substantial proportion of patients with angina and/or ischemia are found to have non‐obstructive coronary arteries (ANOCA/INOCA). Their symptoms can sometimes be explained by coronary microvascular dysfunction and/or vasospasm. Selecting patients for acetylcholine testing remains challenging, and the procedure is not trivial in ...

Simultaneous Assessment of Skeletal Muscle Energetics and Blood Flow During Dynamic Exercise by Interleaved 31P‐MRS/1H‐MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 13-26, July 2026.
ABSTRACT Purpose To simultaneously measure skeletal muscle energetics and blood flow (BF) before, during, and after dynamic plantar flexion exercise (PFE). Methods Non‐localized pulse‐acquire phosphorus‐31 magnetic resonance spectroscopy (31P MRS) and phase contrast flow magnetic resonance imaging (1H MRI) using golden‐angle rotated spiral readouts ...

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.

Invasive Hemodynamic Predictors of Outcomes in Rheumatic Heart Disease With Echocardiographic RV–PA Uncoupling: A Single‐Center Retrospective Cohort Study

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Rheumatic heart disease (RHD) is frequently complicated by pulmonary hypertension (PH) and right ventricular (RV) dysfunction. However, the prognostic significance of invasive hemodynamic parameters obtained at index right heart catheterization (RHC) in adults with RHD and echocardiographic RV–pulmonary artery (PA) uncoupling remains ...

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 ...
