We present a patient with pulmonary arterial hypertension requiring venovenous-extracorporeal membrane oxygenation for acute respiratory distress syndrome. Refractory hypoxemia secondary to right-to-left interatrial shunting via a patent foramen ovale was discovered. Right heart catheterization with invasive occlusion test heralded worsening right heart failure so closure was aborted. ().

Metabolomic Analysis of Patients With Patent Foramen Ovale and Migraine Using Liquid Chromatography-Mass Spectrometry Technology.

Objective: This study aims to examine the changes in metabolic profiles in patients with patent foramen ovale (PFO) and migraine, as well as in patients with isolated migraine, before and after surgical intervention using metabolomics.
Methods: Patients were categorized into four groups: the simple migraine (SM) group, the PFO with migraine preoperative group (PRE), the PFO with migraine postoperative Day 3 group (POST_3d), and the PFO with migraine postoperative Day 30 group (POST_30d). Untargeted metabolomics using liquid chromatography-mass spectrometry (LC-MS) were employed to identify differential metabolites across these groups.

A thrombus straddling a patent foramen ovale (TSPFO) is a rare condition that presents significant health risks, including stroke or myocardial infarction, and can be life-threatening if not promptly addressed. We report the case of a 42-year-old female with morbid obesity who presented with sudden shortness of breath due to a bilateral pulmonary embolism. Imaging revealed a thrombus extending from the right atrium to the left atrium through the patent foramen ovale (PFO).

The VACTERL (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities) association represents an enigmatic syndrome requiring further study. This report describes a full-term neonate born to a multiparous woman who was found, upon further examination, to have multiple congenital abnormalities, including a bicuspid aortic valve, patent foramen ovale, tracheoesophageal fistula (TEF), asymmetric crying facies, microphallus, and a single inguinal testis. The discussion explores environmental and genetic factors that may contribute to this association, as well as similar conditions, such as CHARGE (coloboma, heart defects, choanal atresia, growth retardation, genital abnormalities, and ear abnormalities) syndrome.

Background: About 30% of ischemic strokes do not have a clear cause, which is called cryptogenic stroke (CS). Increasing evidence suggests a potential link between CS and right-to-left shunt (RLS). RLS may lead to CS via paradoxical embolic mechanism.

Background: Ebstein's anomaly represents 40% of congenital tricuspid valve abnormalities. Studies about paediatric Ebstein's anomaly patients are limited.
Aim: To evaluate clinical characteristics, treatment (medical/arrhythmia ablation/surgical) results, and outcome of Ebstein's anomaly patients, and to determine factors affecting arrhythmia presence and mortality.
