Impact of Preoperative Hemodynamic Values on Development of Reperfusion Edema After Pulmonary Endarterectomy

Pulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT Reperfusion pulmonary edema (RPE) is a severe complication after pulmonary endarterectomy (PEA) and is associated with prolonged mechanical ventilation, organ dysfunction, and worse outcome. While residual pulmonary hypertension after PEA is associated with RPE, studies on preoperative risk factors for RPE after PEA are scarce. We investigated

Ivabradine Preserves Cardiac Structure and Reduces Cell Death in Four Dogs With Preclinical Mitral Valve Disease

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Reduces cardiac remodelling and apoptosis in dogs with MMVD stage B2: Long‐term treatment with ivabradine in dogs with asymptomatic myxomatous mitral valve disease (MMVD) stage B2 reduced heart rate without impairing cardiac function. ABSTRACT Background Ivabradine, a specific funny channel blocker, has shown cardiovascular benefits in humans and ...

Ultrasound guided pulmonary artery catheter insertion: An alternative to fluoroscopic guidance

Respiratory Medicine Case Reports, 2022
Pulmonary artery catheters (PACs) can provide extremely valuable objective data in select patients. They are usually advanced by floatation of balloon tip along the normal blood flow and their placement is confirmed under pressure waveform guidance ...

Loop Diuretic Therapy in Severe Aortic Stenosis: Marker of Organ Congestion, Unfavorable Hemodynamics, and Increased Post‐Valve Replacement Mortality

Clinical Cardiology, Volume 48, Issue 12, December 2025.
Aortic stenosis patients on loop diuretic therapy have more evidence of congestion, higher filling pressures, and lower cardiac index, worse functional status several months after aortic valve replacement, and higher long‐term mortality after valve replacement than those without.

First evaluation of a novel pulsatile LVAD: Feasibility and haemodynamic impact in acute heart failure

ESC Heart Failure, Volume 12, Issue 6, Page 4171-4183, December 2025.
The pulsatile ventricular assist platform (pVAP) was connected to a membrane pump in six large swine models. The system, driven by a conventional intra‐aortic balloon pump console (IABP), was utilized to drain left atrial blood during systole and to eject the collected blood back into the ascending aorta during diastole.

Exercise‐induced out‐of‐proportion increase in afterload and impaired right ventricular contractile reserve in HFpEF

ESC Heart Failure, Volume 12, Issue 6, Page 4391-4400, December 2025.
Non‐cardiac dyspnoea (n = 34, NCD) and heart failure with preserved ejection fraction (n = 34, HFpEF) patients were classified according to right heart catheterisation. Cardiovascular magnetic resonance derived right ventricular (RV) haemodynamic indices for afterload (Ea), contractility (Ees) and RV/pulmonary artery coupling (Ea/Ees) were evaluated ...

Echocardiography versus right heart catheterization in class I pulmonary hypertension

Egyptian Journal of Chest Disease and Tuberculosis, 2014
It has been agreed that pulmonary hypertension should be determined by right heart catheterization. However, being invasive and refused by many patients, echocardiography was thought to be a reasonable substitute to determine a solid diagnosis of ...

Biplanar Angiography through Swan-Ganz Catheters [PDF]

Anaesthesia and Intensive Care, 1980
Twenty-eight patients had biplanar angiography performed through wedged Swan-Ganz Catheters. In only five cases were the catheter tips symmetrically placed within the vessels in both AP and lateral views. The value of performing angiography immediately after placement of a Swan-Ganz catheter is discussed.

Exercise haemodynamics in pulmonary hypertension – a prospective pressure–volume loop study on right ventricular adaptation and prognosis

European Journal of Heart Failure, Volume 27, Issue 12, Page 3180-3192, December 2025.
Multimodal assessment during exercise distinguishes clinically relevant right ventricular (RV) adaptation patterns (homeometric and heterometric adaptation) in pulmonary hypertension. Disease controls are patients with invasive exclusion of pulmonary hypertension.
