Direct Fick (DF) and bolus thermodilution (TD) are endorsed by pulmonary hypertension (PH) guidelines to measure cardiac output. In contemporary practice, agreement between methods is unknown, as are the diagnostic consequences of disagreement. 

Epoprostenol is a prostaglandin that was first identified by investigators in 1976 and found to be a potent vasodilator and inhibiter of platelet aggregation, initially in animal studies and subsequently in humans.

Perspectives on Global Epidemiology Challenges is part of the Virtual Symposium series by the iPVD, a global education programme that highlights top-notch research on inflammation and infectious PVD.

Although right ventricle (RV) dysfunction drives clinical worsening in pulmonary hypertension (PH), information about RV function has not been well integrated in PH risk assessment. The gold standard for assessing RV function and ventriculo-arterial coupling is the construction of multi-beat pressure–volume (PV) loops.

In the study “Echocardiographic grading of right ventricular afterload in left heart disease: relation to right ventricular function, pulsatile and resistant load, and outcome,” Bech-Hanssen et al. addressed an interesting topic about severity gradation using right ventricular (RV) afterload echocardiographic assessment.

Presentations: Is there evidence for different phenotypes of PH in ILD? Treatment of pulmonary vascular disease in ILD: as early as possible or only in severe PH?

The history of advances in understanding pulmonary circulation is long, dating to the 13th century. Subsequent centuries produced halting progress until the 20th century when investigators applied right heart catheterization and light-microscopy to better understand the physiology and pathology of pulmonary hypertension (PH). The work of Paul Wood, Cornelis Wagenvoort, and others during the first seven decades of the 20th century set the stage for five decades of extraordinary progress.

Transcription factor TBX4 rare variants associate with pulmonary arterial hypertension (PAH), particularly in children, and are the second most common cause of heritable PAH. However, TBX4's down-stream targets and the molecular and cellular pathways these targets regulate remain largely unknown in PAH. 

Pulmonary hypertension (PH) in newborn babies is a relatively rare, heterogeneous condition that has high associated mortality in the neonatal period and beyond. There are limited evidence-based strategies to treat or prevent this condition.

Pulmonary hypertension (PH) constitutes a critical challenge in cardiopulmonary medicine with a pathogenesis that is multifaceted and intricate. Ion channels, crucial determinants of cellular electrochemical gradient modulation, have emerged as significant participants in the pathophysiological progression of PH.
