Pulmonary vein stenosis and the pathophysiology of “upstream” pulmonary veins

The Journal of Thoracic and Cardiovascular Surgery, 2014
Surgical and catheter-based interventions on pulmonary veins are associated with pulmonary vein stenosis (PVS), which can progress diffusely through the "upstream" pulmonary veins. The mechanism has been rarely studied. We used a porcine model of PVS to assess disease progression with emphasis on the potential role of endothelial-mesenchymal transition

Cardiovascular agents affect the tone of pulmonary arteries and veins in precision-cut lung slices.

PLoS ONE, 2011
IntroductionCardiovascular agents are pivotal in the therapy of heart failure. Apart from their action on ventricular contractility and systemic afterload, they affect pulmonary arteries and veins. Although these effects are crucial in heart failure with

Pulmonary Vein in a Pinch

Methodist DeBakey Cardiovascular Journal
The pulmonary veins normally drain into the left atrium, with the superior pulmonary veins typically situated anterior and inferior to the right pulmonary arteries. However, anomalies can happen.

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 ...

Cryoballoon Pulmonary Vein Isolation with Real‐Time Recordings from the Pulmonary Veins [PDF]

Journal of Cardiovascular Electrophysiology, 2009
Introduction: Cryoballoon (CB) ablation represents a novel technology for pulmonary vein isolation (PVI). We investigated feasibility and safety of CB‐PVI, utilizing a novel spiral catheter (SC), thereby obtaining real‐time PV potential registration.

Variations in the Pulmonary Venous Ostium in the Left Atrium and Its Clinical Importance [PDF]

Journal of Clinical and Diagnostic Research, 2014
Introduction: During early embryonic development, absorption of pulmonary venous network by the left primitive atrial chamber results in opening of four pulmonary veins which drain independently into its chamber.
