A Distinctive Strategy for Catheter Ablation in Patients With Bilateral Common Ostium in the Inferior Pulmonary Veins: A Case Report [PDF]

Clinical Case Reports
Pulmonary vein anatomical variations are frequently observed in atrial fibrillation patients undergoing catheter ablation. However, when it comes to patients with atrial fibrillation and bilateral common ostium in the inferior pulmonary veins, using a ...

Anatomic Study of Number of Pulmonary Veins Draining into the Left Atrium and Their Variations

Journal of Medical Sciences and Health, 2020
Introduction: Pulmonary veins originate from the alveolar capillary plexus and carry oxygenated blood to the left atrium. The fibrous pericardium is perforated by the pulmonary veins and they drain separately in the posterosuperior aspect of the left ...

Common pulmonary vein atresia [PDF]

Cardiology in the Young, 2021
AbstractA 4-hour-old infant with profound cyanosis on an alprostadil infusion was urgently transferred to Rady Children’s Hospital with suspected CHD. Upon arrival, urgent echocardiography was performed but could not confirm the presence of discrete pulmonary veins or pulmonary venous drainage. Given the difficulty in delineating the anatomy, a cardiac
