Fetal-to-Neonatal Transition of an Infant with Transposition of the Great Arteries and Intact Ventricular Septum: A Case Report.
Biomed Hub
December 2024
Division of Paediatric Cardiology, Department of Paediatrics, Willem-Alexander Children's Hospital, Leiden University Medical Centre (LUMC), Leiden, The Netherlands.
Introduction: Transposition of the great arteries (TGA), especially with intact ventricular septum (TGA-IVS), presents unique challenges during fetal-to-neonatal transition, which can contribute to developing persistent pulmonary hypertension of the newborn (PPHN).
Case Presentation: A male newborn with TGA-IVS, delivered via caesarean section, presented with hypoxemia and tachycardia immediately after birth (preductal SpO: 50-60%, post-ductal SpO: 70-75%). Echocardiography revealed a floppy interatrial septum and two interatrial connections with bidirectional shunting.

Background: The epicardial connections (ECs) via intercaval fibres connecting the right-sided pulmonary veins (PVs) and right atrium (RA) can preclude isolation of the right-sided PVs. Such ECs occasionally have a unidirectional conduction property.
Case Summary: A 62-year-old man was referred to our institution for catheter ablation of paroxysmal atrial fibrillation (PAF).

Morphological and Histological Studies of the Bronchial and Parabronchial System of the White Pekin Duck (Anas platyrhynchos).

Department of Anatomy and Embryology, Faculty of Veterinary Medicine, Damanhour University, Damanhour, Egypt.
The present study aimed to provide comprehensive morphological features of the bronchial and parabronchial systems using cast, histological, histochemical, and scanning electron microscopy techniques, with new insights into the parabronchial topographic distribution system on 22 white Pekin ducks. Casting illustrated that the medioventral secondary bronchi (MVSB) were the largest, but the posterior (POSB) ones were the smallest. The primary (PB) and secondary bronchi (SB) were lined with thin pseudostratified, ciliated columnar epithelium.

Division of Cardiology, Gunma Prefectural Cardiovascular Center, Maebashi, Gunma, Japan.
Background: Epicardial connections from surrounding structures to the right pulmonary vein (PV) antrum impede PV isolation.
Objective: This study aimed to evaluate the efficacy of an ablation approach targeting epicardial connections for right PV isolation.
Methods: We prospectively enrolled 124 patients with atrial fibrillation undergoing initial PV isolation.
