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 ...

Minimally Invasive Porcine Model for Chronic Thromboembolic Pulmonary Hypertension

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
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.

The Relationship Between Vortical Flow and Pressure Gradient Reversal in Pulmonary Hypertension—A 4D Analysis of Cardiovascular Magnetic Resonance Flow Imaging

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
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 ...

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 ...

Zero-Heat-Flux Thermometry for Non-Invasive Measurement of Core Body Temperature in Pigs.

PLoS ONE, 2016
Hypothermia is a severe, unpleasant side effect during general anesthesia. Thus, temperature surveillance is a prerequisite in general anesthesia settings during experimental surgeries.

Right Ventricular to Left Ventricular (RV/LV) Blood Pool T2 Ratio Is Associated With Invasive Hemodynamics Across Pulmonary Hypertension Subgroups

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Pulmonary hypertension (PH) is defined by elevated mean pulmonary arterial pressure (mPAP). Pulmonary vascular resistance (PVR) and SvO2 (mixed venous oxygenation), measured by right heart catheterization (RHC), are key determinants of disease severity and prognosis.

Paradoxical Rise in Pulmonary Artery Pressure Following Successful Mavacamten Therapy for Obstructive Hypertrophic Cardiomyopathy: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT A paradoxical rise in pulmonary artery pressure on follow‐up echocardiography after successful mavacamten therapy for obstructive hypertrophic cardiomyopathy (oHCM) prompted right heart catheterization, which demonstrated combined pre‐ and post‐capillary pulmonary hypertension and guided the decision to continue mavacamten while withholding ...

Animal models of chronic thromboembolic pulmonary hypertension

Animal Models and Experimental Medicine, Volume 9, Issue 5, Page 886-897, May 2026.
Current animal models of CTEPH. Created using BioRender.com. Abstract Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, yet life‐threatening disorder characterized by persistent pulmonary vascular obstruction and elevated pulmonary artery pressure, with progressive remodeling and subsequent right heart failure.
