Right heart catheterisation is a frequently used procedure in cardiology and intensive care medicine, especially for the differential diagnosis of pulmonary hypertension, shunt diagnostics and accurate calculation of the important haemodynamic parameters. Various catheters are available for the examination; the most common and safest is the use of a Swan-Ganz catheter. The complete examination includes probing of the right atrium, right ventricle, pulmonary artery and pulmonary capillary bed. In this "step-by-step" article, the authors discuss the practical aspects of this method.

Determining the QRS axis: visual estimation is equal to calculation.
Herzschrittmacherther Elektrophysiol
January 2025
Hannover Heart Rhythm Center, Department of Cardiology & Angiology, Hannover Medical School, Carl-Neuberg Str. 1, 30625, Hannover, Germany.
Background: The QRS axis of the electrocardiogram (ECG) is often considered in clinical practice, but its determination is frequently limited to a rough estimation, such as "normal", with left or right deviation, and superior or inferior in the case of premature ventricular complexes (PVCs). However, a more exact determination of the QRS axis may be warranted in certain scenarios, such as to determine the origin of PVCs more precisely, and is attainable by visual estimation using the hexaxial reference system.
Objectives: The aim of this study was to determine how well such an estimation of the QRS axis would correlate with the axis calculated by formulas.
RNA-sequencing unveils FLT4 splice site variants in variable congenital heart disease.
Eur J Hum Genet

Center for Medical Genetics, Ghent University Hospital, Ghent, Belgium.
The etiology of congenital heart disease (CHD) is complex, comprising both genetic and environmental factors. Despite documented familial occurrences, the genetic etiology remains largely elusive. Trio exome sequencing identified a heterozygous FLT4 splice site variant in two families with respectively tetralogy of Fallot (TOF), and variable CHD comprising both the TOF spectrum and aortic coarctation.

Background: Little is known about the very long-term outcome in Tetralogy of Fallot (ToF) patients.
Objectives: To prospectively evaluate clinical outcome and quality-of-life after surgical repair of ToF.
Methods: Single-centre, longitudinal cohort-study evaluating every decade 144 ToF patients who underwent surgical repair <15 years of age between 1968 and 1980.
Targeted FTO knockout in endothelial cells Boosts adhesion and lowers inflammatory infiltration to alleviate pulmonary arterial hypertension.

January 2025
Department of Ultrasonography, Fuwai Yunnan Hospital, Chinese Academy of Medical, Sciences/Affiliated Cardiovascular Hospital of Kunming Medical University, Kunming, 650102, China. Electronic address:
Pulmonary arterial hypertension (PAH) is a syndrome characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, ultimately leading to right heart failure and even death. Increasing evidence implicates the fat mass and obesity-associated protein (FTO) in various metabolic and inflammatory pathways; however, its role in pulmonary endothelial function and PAH remains largely unexplored. In this study, we examined the effects of endothelial cell-specific FTO knockout on PAH development.

Background: Plasma exchange (PE) removes high-molecular-weight substances and is sometimes used for antineutrophil cytoplasmic antibody-associated vasculitis (AAV) with alveolar hemorrhage. Hypotension during PE is rare, except in allergic cases. We report a case of shock likely caused by increased pulmonary vascular resistance (PVR) during PE.
