Magnetohydrodynamic Effect

  • 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.

Marfan Syndrome

  • Autosomal dominant mutations in fibrillin gene.

  • Incidence: 1/5,000–10,000.

  • 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)...
