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 ...

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 ...

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.

Magnetocardiography combined with machine learning for pulmonary hypertension detection and improved short‐term risk assessment

Interdisciplinary Medicine, Volume 4, Issue 3, May 2026.
Magnetocardiography (MCG) enables non‐invasive mapping of cardiac magnetic fields. In this study, an MCG‐based machine learning model detects pulmonary hypertension with robust performance. Furthermore, MCG features may improve the accuracy of short‐term risk assessment.

From research lab to routine procedure: A case study of the Swan-Ganz catheter, 1965-1980 [PDF]

, 2001
This study analyzes the process by which the Swan-Ganz catheter (flow-directed pulmonary artery catheter) was adopted into routine care of critically ill patients in the U.S. between 1965 and 1980.

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 ...

Myocardial oxygen consumption, myocardial efficiency, and mechanical efficiency: A review across pathologic and physiologic states

Physiological Reports, Volume 14, Issue 10, May 2026.
Abstract Myocardial work and oxygen consumption (MVO2) are tightly coupled. The patient's physiological state, presence of disease, heart rate, and microvascular control of oxygen delivery all combine to maintain this relationship. The myocardial efficiency (MyoEff) of the heart is determined by the ratio of stroke‐work (SW) divided by MVO2, whereas ...
