tetralogy of fallot | classified as a cyanotic heart defect because the condition causes low oxygen levels in the blood that usually includes a combination of 4 defects: pulmonary stenosis, ventricle septal defects, overiding aorta, hypertrophy of right ventricle |
largest chamber of the heart | left ventricle |
what is patent ductus arteriosus | abnormal persistence of an open ductus arteriosus after birth, resulting in recirculation of arterial blood thru the lungs |
radiographic appearance of coarctation of the aorta | two bulges of the aorta are demonstrated in the aortic arch region, one superior to and one inferior to the stenosis; rib notching- well defined bony erosions along the lower rib margins as a result of the enlargement of anastomotic vessels |
