    en.wikipedia.org/wiki/Catheter_ablation

    Catheter ablation may be recommended for a recurrent or persistent arrhythmia resulting in symptoms or other dysfunction. Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [1] Pulmonary vein isolation by transcatheter ablation can restore sinus ...

    en.wikipedia.org/wiki/Chronic_venous_insufficiency

    Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]

    Pulmonary vein isolation by transcatheter ablation can restore sinus rhythm. [15] The ganglionated plexi (autonomic ganglia of the heart atrium and ventricles) can also be a source of atrial fibrillation, and is sometimes also ablated for that reason. [16]

    Pulmonary vein stenosis can be congenital or acquired. [6]A rare abnormality that accounts for 0.4% of congenital heart diseases, congenital pulmonary vein stenosis results from the common right or left pulmonary vein failing to integrate into the left atrium (LA) during the vessel's embryonic development, obliterating the pulmonary veins partially or completely on one or both sides.

    CHIVA method is a type of surgery used to treat varicose veins that occur as a result of long term venous insufficiency. [1] The term is a French acronym for Conservatrice Hémodynamique de l'Insuffisance Veineuse en Ambulatoire (ambulatory conservative hemodynamic treatment venous insufficiency).

  7. Telangiectasia - Wikipedia

    en.wikipedia.org/wiki/Telangiectasia

    Varicose veins and reticular veins are often treated before treating telangiectasia, although treatment of these larger veins in advance of sclerotherapy for telangiectasia may not guarantee better results. [18] [19] [20] Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open
