Pulmonary vein isolation by transcatheter ablation can restore sinus rhythm. [4] As atrial fibrillation becomes more persistent, the junction between the pulmonary veins and the left atrium becomes less of an initiator and the left atrium becomes an independent source of arrhythmias. [6] Pulmonary vein isolation ablation technology has used ...
Scimitar syndrome, or congenital pulmonary venolobar syndrome, is a rare congenital heart defect characterized by anomalous venous return from the right lung (to the systemic venous drainage, rather than directly to the left atrium). [1] This anomalous pulmonary venous return can be either partial (PAPVR
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.
Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which the pulmonary veins drain into the right side of the heart instead of the left, as is usually seen. This can happen within the heart (intracardiac) where it drains into the coronary sinus or ...
In persistent left superior vena cava, the left brachiocephalic vein does not develop fully and the left upper limb and head and neck drain into the right atrium via the coronary sinus. [ 5 ] In isolation, the variation is considered benign, but is very frequently associated with cardiac abnormalities (e.g. ventricular septal defect ...
Factor V Leiden (rs6025 or F5 p.R506Q [1]) is a variant (mutated form) ... Having a first DVT (deep vein thrombosis) or PE (pulmonary embolism) before age 50.
The characteristic findings of misplaced pulmonary veins adjacent to pulmonary arteries, and abnormal alveolar and capillary development confirm the diagnosis. [1] FOXF1 genetic testing is also available, which can confirm the diagnosis without invasive testing. [2] There are no effective treatments for severe ACD.
