Chapter 3: Cardiovascular Flashcards
Acyanotic: ASD, VSD and PDA
Left to right shunts
Cyanotic: Tetralogy of Fallot, transposition of great vessels
Right to left shunts
Pulmonary stenosis, right ventricular hypertrophy, overriding aorta, VSD
Fallot’s tetralogy
Formed by the edge of the septum secundum
Limbus of fossa ovale
Right atrium, right ventricle, 30% of the left atrium, posterior 1/3 of IV septum
Right coronary artery
Left ventricle, 70% of left atrium and anterior 2/3 of the IV septum
Left coronary artery
Upper part of the right atrium, near the opening of the superior vena cava
Sinoatrial node
Lower part of the right atrium, near the opening of the coronary sinus
Atrioventricular node
Brachiocephalic trunk, left common carotid and left subclavian arteries
Arch of the aorta branches
Bronchial, esophageal, and 3rd-11th posterior intercostal arteries
Thoracic aorta branches
4 unpaired visceral, 4 paired visceral and 4 paired parietal branches
Abdominal aorta branches

4 paired visceral branches
Four lumbar arteries
4 parietal branches
Posterior division: illiolumbar, lateral sacral, and superior gluteal arteries
Internal iliac branches
Cremasteric, inferior epigastric, and deep circumflex arteries
External iliac branches

Deep palmar arch
From medial dorsum of foot, in front of ankle, behind the knee to the groin
Great saphenous vein
A branch of the femoral nerve that accompanies the great saphenous vein below the knee
Saphenous nerve
Joining of common iliac veins at L5, to the right of the abdominal aorta
Inferior vena cava origin
Lumbar, renal, right adrenal, inferior phrenic and hepatic veins
IVC tributaries
Accompanies superior thyroid artery and vein
