Electrophysiology of Pulmonary Veins
Journal of Cardiovascular Electrophysiology, 2005Pulmonary veins were found to be important foci for the genesis and maintenance of atrial fibrillation. Morphological studies have demonstrated the presence of complex anatomic structures and different types of cardiomyocytes in pulmonary veins. Numerous studies have suggested that the combination of reentrant and nonreentrant mechanisms (automaticity ...

Atrial fibrillation (AF) is a common cardiac rhythm disturbance and its incidence is increasing. Radiofrequency catheter ablation (RFCA) is a highly successful therapy for treating AF, and its use is becoming more widespread; however, with its increasing use and evolving technique, known complications are better understood and new complications are ...

Pulmonary Arteriography in Pulmonary Vein Stenosis
Journal of Invasive Cardiology, 2020A 43-year-old woman underwent radiofrequency pulmonary vein ablation for symptomatic paroxysmal atrial fibrillation. At 3 months, she developed worsening dyspnea and exercise intolerance; tests revealed severe stenosis in her right pulmonary veins at the venoatrial junction and an abnormally small left atrium.

Anomalies of the pulmonary veins∗
The American Journal of Cardiology, 1967Abstract Eighty pathologic specimens with anomalies of pulmonary veins were reviewed for the type of lesions encountered. These were classified on an anatomic basis into five groups, characterized by (1) stenotic lesions; (2) accessory veins; and (3) anomalous connection of pulmonary veins (a) either partial or total, to a systemic vein or right ...

Human Pathology, 1995
Pulmonary vein stenosis (PVS) is a rare disorder. Accurate diagnosis often requires anatomical examination. We report four children with pulmonary vein stenosis. Autopsy showed bilateral lesions in two patients who were thought clinically to have unilateral disease. A diagnosis of PVS was made at autopsy in the third case.

American Journal of Roentgenology, 1977
Chest injuries have become more common due to the increasing number of motor vehicle accidents. In such cases, it is necessary to exclude serious underlying visceral damage. When the lung is injured, minor lacerations heal spontaneously, while more severe injury produces persistent collapse and leakage of air and blood into the pleural cavity.

Abstract The literature now embodies 133 case reports of anomalous drainage of pulmonary veins. Of these patients, partial drainage into the right atrium occurred in 75, and complete drainage into this chamber or its tributaries occurred in 56. Additional cardiovascular anomalies were present in 23 of the latter group of patients. Partial drainage of

Pulmonary Vein Atresia with Severe Contralateral Pulmonary Vein Stenosis in a Child
Pediatric Cardiology, 2012Unilateral pulmonary vein atresia is a very rare congenital anomaly associated with high morbidity and mortality. Most cases present in infancy or childhood with recurrent respiratory infections or hemoptysis. Further, the diagnosis can often be difficult to make.

Congenital Narrowing of a Pulmonary Vein: Slit‐like Pulmonary Vein Ostium
Pacing and Clinical Electrophysiology, 2011We report the case of a 60‐year‐old female with a history of refractory paroxysmal atrial fibrillation. Preablation contrast enhanced pulmonary vein computed tomography (CT) scan demonstrated a slit‐like narrowing of the left inferior pulmonary vein ostium. The narrowing measured approximately 3 mm, with poststenotic dilation.

Cardiac Veins and Pulmonary Veins
2012In the field of noncoronary applications of cardiac CT the study of the cardiac and pulmonary veins is of great use for the cardiologist, the former particularly in patients with heart failure who require electrical resynchronization of the cardiac chambers (cardiac resynchronization therapy or biventricular pacing) and the latter in patients scheduled
