AI Article Synopsis
- A 23-year-old man presented unconscious with low oxygen levels (hypoxemia) and was diagnosed with biventricular non-compaction cardiomyopathy, showing structural heart defects (VSD and ASD).
- Doppler echocardiography indicated abnormal blood flow patterns: a left-to-right shunt through the ventricular septal defect and a right-to-left shunt through the atrial septal defect.
- Cardiac catheterization showed high pressure in the right atrium but normal pulmonary pressure, suggesting that the right-to-left shunt from the ASD contributed to his hypoxemia primarily due to right ventricular dysfunction, rather than pulmonary hypertension.
Article Abstract
Echocardiography and magnetic resonance imaging revealed biventricular non-compaction cardiomyopathy with ventricular (VSD) and atrial (ASD) septal defects in an unconscious, 23-year-old hypoxemic man. Doppler echocardiography showed a left-to-right shunt across the VSD and a right-to-left shunt across the ASD. Cardiac catheterization revealed elevated right atrial pressure, although pulmonary pressure was normal. We considered that the atrial right-to-left shunt had induced the hypoxemia, which was related mainly to right ventricular dysfunction in this biventricular non-compaction cardiomyopathy, but it was not related to pulmonary hypertension.

Caval vein obstruction resulting in right to left shunt and desaturation post-endocardial pacing implantation in a 3-year old: a case report.
Eur Heart J Case Rep
January 2025
Echocardiography Department, Great Ormond Street Hospital for Children, Great Ormond Street, London WC1N 3JH, UK.
Background: Superior caval vein obstruction is a rare complication of endocardial pacing lead implantation that can result in a right to left shunt.
Case Summary: A 3-year-old child with type 2 Brugada syndrome presented with mild cyanosis post-endocardial pacing implantation due to evolutionary right superior caval vein obstruction. This obstruction resulted in a right to left shunt across a previously unrecognized patent levo-atrial cardinal vein associated with partial anomalous pulmonary venous drainage.
Patent foramen ovale: A variant of normal or a true congenital heart disease?

Foramen ovale plays a key role in foetal circulation, however it may remain patent after birth throughout the life. Its patency is so frequent in healthy people (27-35 %), such as to be considered a variant of normal. It is at risk of complications, like paradoxical embolism by right to left shunt with stroke, migraine, temporary blindness, as well as aneurysm, thrombosis and endocarditis of the fossa ovalis.

Division of Pulmonary and Critical Care Medicine, Department of Medicine, David Geffen School of Medicine at UCLA, Los Angeles, CA 90095, USA.
Hepatopulmonary syndrome (HPS), defined by the presence of pulmonary vascular dilatations that cause right-to-left transpulmonary shunting of venous blood with a consequential increase in the alveolar-arterial oxygen gradient, is a relatively frequent complication of chronic liver disease. While orthotopic liver transplantation (OLT) is indicated and often curative in HPS patients with end-stage liver disease (ESLD), little is known about the peri- and post-operative-period risks of CVA in OLT recipients with HPS. : We report a case series of five non-consecutive OLT recipients with HPS who developed ischemic and/or hemorrhagic CVAs during or shortly after OLT, raising concern that the risks of neurological complications remain increased even after OLT.

Pneumology Department, University Hospital Centre Amiens-Picardie, Amiens, France; AGIR Unit, University Picardie Jules Vernes, Amiens, France.
Background: SARS-CoV-2 virus which targets the lung vasculature is supposed to affect both pulmonary and bronchial arteries. This study evaluated the tracheobronchial vascularization density observed with narrow band imaging (NBI) in patients hospitalized for COVID-19 pneumonia. To determine if the observed changes were specific of COVID-19 patients, the procedure was also performed in non-COVID-19 patients.

Medicine (Baltimore)

Department of Center for Pulmonary Vascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Rationale: The transcatheter closure and atrioseptopexy are the main treatment methods for atrial septal defect (ASD). However, persistent hypoxemia due to iatrogenic diversion of inferior vena cava (IVC) to the left atrium (LA) is reported as a rare complication after ASD closure. Contrast echocardiology is a reliable and powerful tool to detect iatrogenic diversion and identify the etiology accurately.
