What Does Dominant Left Coronary Artery System Mean?
Yes I failed a stress test and nuclear test in 2008, so cardiologist recommended going thru artery in the groin to check and see what the problem was. After this procedure he said my arteries were very clear and the reason I failed the two stress tests were this I have a left dominant system with small PDA and LAD which does not wrap around. Can someone explain this to me in simple terms and do I need to worry or are there things I can do to head off any problems from this? I am now 63 years old and my doctor says I am in very good health. I do take 10mg Lisonpril for hypertension. Thanks in advance

Hello
thank you for trusting HCM
Dear The posterior descending artery (PDA) supplies the inferior wall of the left ventricle and inferior part of the septum.
The coronary artery that supplies(means originates) the PDA determines coronary “dominance.”
In approximately 70% of the population, the PDA originates from the right coronary artery.
it is codominant in 20%, meaning both the right coronary artery and LCx feed the PDA.and 10% are left dominant, meaning the LCx alone supplies the PDA.
in your condition left circumflex artery supplies blood to your inferior wall of myocardium and interventricular septum through posterior depending artery.
i think i tried to clear your doubt if you have more query please ask.
