Question:
Does Tetralogy of Fallot have anything to do with coronary artery?
Since TOF is congenital, why does it realte to coronary artery?
My cardiologist suggested me have a cardiac catheterization test in order to make sure of my coronary artery is ok. I’d never smoked, seldom drink. What signs dose a patient with abnormal coronary artery have?
Answers:
TOF has nothing to do with your coronary arteries. But getting a cath is still a good idea.
TOF consists of 4 parts ("tetralogy")
1. Ventricular Septal Defect
2. Pulmonic Stenosis
3. Overriding Aorta
4. Right Ventricular Hypertrophy.
In english, what does that mean? Basically, the pulmonary artery that carries blood to your lungs is rather tight. In addition, you have a small hole between the right and left ventricle (the septal defect). Because the pulmonary artery is so tight, blood that would have gone through the artery instead gets shunted across the septal defect into the left heart, bypassing the lungs. As a result, your oxygen levels can drop because some blood that never got oxygen is going into your systemic circulation.
A catheterization involves the placement of long flexible catheters into your heart. If they point the catheters into your coronary arteries and shoot dye, they can see how tight those arteries are. But, even when they don't, they can still take blood pressure measurements and oxygen measurements in the heart that let you know exactly how much blood is bypassing the lungs and going into the circulation.
