Anomalous voltage detected by ECG caused by ions in the blood influenced by the magnetic field.
Leads to ECG alterations on the T waves, which appears largest.
Major Aortopulmonary Collateral Arteries
MAPCAs: arteries originating from descending aorta and transverse aortic arch to vascularize the lungs.
Usually associated with pulmonary atresia and ventricular septal defect.
Describe origin caliber, course, relationship with airways, and pulmonary territories supplied.
Abrupt reduction in caliber of MAPCAs is protecting the pulmonary circulation from higher systemic pressure.
MAPCAs visualization: CT > MR.
Autosomal dominant mutations in fibrillin gene.
Cardiovascular anomalies: (1) ascending aorta dilatation with sinus of Valsalva involvement; (2) aortic dissection; (3) aortic valve regurgitation; (4) mitral valve prolapse and regurgitation; (4) main pulmonary artery dilatation; (5) mitral annulus calcification; (6)...
