Pressure monitoring predicts pulmonary vein occlusion in cryoballoon ablation
Journal of Interventional Cardiac Electrophysiology, 2018Pulmonary venography is routinely used to confirm pulmonary vein (PV) occlusion during cryoballoon ablation. However, this technique is significantly limited by the risks associated with contrast media, such as renal injury and contrast allergy. We hypothesized that PV occlusion can be predicted by elevation of the balloon catheter tip pressure ...

Thoracoscopic Radiofrequency Pulmonary Vein Isolation and Atrial Appendage Occlusion
The Annals of Thoracic Surgery, 2007A 46-year-old woman with a 7-year history of profoundly symptomatic daily paroxysmal atrial fibrillation had undergone two percutaneous catheter ablations and multiple medication trials. With informed consent, bilateral pulmonary vein isolation and left atrial appendage occlusion as well as ablation of ganglionated plexi were performed by a totally ...

Non‐Occlusive Separate Freezing for Cryoballoon Pulmonary Vein Isolation to the Large Pulmonary Vein
Pacing and Clinical ElectrophysiologyAbstractBackgroundCryoballoon pulmonary vein (PV) isolation (PVI) requires PV occlusion, which can be challenging to the large PV. The non‐occlusive separate freezing, which involves freezing the superior and inferior portions of the PV ostium without complete occlusion, is often useful in these situations. This study aimed to evaluate the efficacy and

Fibrosing Mediastinitis and Occlusion of Pulmonary Veins After Radiofrequency Ablation
The Annals of Thoracic Surgery, 2009Pulmonary vein stenosis is a known complication of radiofrequency ablation; its incidence ranges from 8% to 50%. However, complete occlusion of unilateral pulmonary veins is uncommon. We report a case with radiofrequency ablation that was complicated by complete occlusion of pulmonary veins along with fibrosing mediastinitis, which we believe has not ...

Fifteen Micrometer Microspheres Reflux Up the Pulmonary Veins during Pulmonary Artery Occlusion
Microvascular Research, 1993The systemic arterial blood supply to the lung (bronchial blood flow, Qbr) is commonly measured using the reference flow technique by injecting radiolabeled microspheres into the left atrium (LA) and simultaneously collecting a reference blood sample from a large artery such as the aorta.

Pulmonary Vein Occlusion Successfully Treated by Stenting with Intravascular Ultrasound Guidance
Heart, Lung and Circulation, 2015Pulmonary vein (PV) stenosis (PVS) is a known complication of PV isolation procedures for AF (atrial fibrillation). PV angioplasty and stenting have been used as an effective therapy for PVS, yet high rates of restenosis are common. Experience with intravascular ultrasound (IVUS) in evaluating the PVS morphological characteristics and appropriate stent

Right Pulmonary Vein Occlusion Detected by Ventilation -Perfusion Lung Scanning
Clinical Nuclear Medicine, 1985Absence of perfusion of a right lung was initially misinterpreted as pulmonary embolic disease. Pulmonary angiography revised this diagnosis to obstruction of the right pulmonary vein.

Catheterization and Cardiovascular Interventions, 2011
AbstractAcquired pulmonary vein occlusion is a rare complication of surgical correction of complex congenital heart diseases. Associated vascular remodeling of arterial and venous vessels includes medial thickening, intimal fibrosis, and progressive development of aorto‐pulmonary collaterals.

Catheterization and Cardiovascular Interventions, 2015
We describe a case of a scimitar syndrome “variant” where dual drainage existed from the right upper and middle pulmonary veins to the inferior vena cava and left atrium. Device closure of the anomalous vein at the level of the connection to the IVC was successful in achieving diversion of pulmonary venous flow to the left atrium. Vigilance during work‐
