<s>[INST] I have an 87 yr old dad. He went into emergency with a diagnosis of heart disease. He recently had a tube ran through his thigh area to see if there was any additinal issues. There has been a leaky valve detected.could he have been miss diagnosed with heart disease and the on.y issue a leaky valve. I guess my question is; can a leaky valve have the same symptoms as heart disease and maybe he doesn’t have heart disease? [/INST] Hello After going through your medical details, I understand your concern about your father’s health and I would like to tell you that all heart diseases can have resembling symptoms and leaky valve is in itself a cardiac disease. Angiogram would have been done to diagnose coronary artery disease so that if he has to get his valve replaced then coronary artery disease should also get managed at the same time. Hope I have answered your query. Let me know if I can assist you further. </s>
