Hello. Thank you for your question and welcome to HCM. I read your query and understood your concerns. Allow me to start my answer with an analogy. Stent placement in a coronary artery is a remedy to the artery, as it is taking antibiotics when you have sore throat. If there is a blockage greater than 60%, then placing a stent is reasonable. There are no drugs or therapeutic remedies that would cause regression ( growing down ) of the intracoronary atherosclerotic plaque. With the maximum of usage and dosage, they could stop it from building up, at best. Percutaneous coronary intervention (PCI: balloon + stent) is a safe and effective treatment of intracoronary plaques. It is accompanied with a great deal of symptom relief. With the right and proper care after the stent implantation, it should be successful. As about the fractional flow reserve, it is used by the operator when he has doubts whether to deploy a stent or not. In this term, I would only speculate if I gave you a precise answer, because I would had to see it myself. Summing up, my opinion and recommendation is that, if that plaque results over 70% in coronary angiogram, a stent should be implanted. At the end, the choice is always yours. I hope I was helpful. Take care and good luck!
