Question
Fat Albert is having heart trouble. His doctor suspects that he has a blocked coronary artery. The doctor decides to do a cardiac catheterization.
If the cardiologist inserted the catheter into the patient’s right radial artery (a relatively new technique for this procedure), which arteries would the tube have to pass through in order to reach the entrance of the left coronary artery?
Beginning with the Right Radial Artery: (Be specific when necessary: Use right or left and artery or vein)
From the artery in question 4, the tube would move through the ______ _______.
From the artery in question 5, the tube would move through the _____ ______ _____.
The results of Fat Albert’s cardiac catheterization show 90% blockage of the Left Main Coronary Artery just before the Anterior Interventricular Artery begins.
2 What two arteries does the left main coronary artery split into? Use complete names of the arteries?
3. Will the blockage affect blood flow through both of these arteries, yes or no?
4 . Which parts of the heart, be specific as to location and chamber, will be affected by the blood flow blockage?
Explanation / Answer
Beginning with the radial artery the catheter travels from right radial artery to right brachial artery then right subclavian artery and the acsending aorta to left coronary artery.
2. The left main coronary artery splits into circumflex artery and left anterior descending artery (LAD).
3. According to the position of blockage in left coronary artery the flow through the two branches will be affected. If blockage is found in left coronary artery the blood flow will be less.
4. Left coronary artery supplies blood to the front side of the heart especially left ventricle and left auricle.
