Hello, Thanks for writing to Health Care Magic, I am Dr Muhammd Ahmad, I have closely read your question and I understand your concerns, I will hereby guide you regarding your health related problem. Surgery is usually considered after considering the pros and cons of the surgery , a surgeon would generaly weigh benefits over risks to see if he wants to do a surgery or not. A calcified valve only becomes an indication for surgery if it gets narrow enough that function of heart is compromised, patient faces black outs, heart failure shortness of breathe episodes, chest pain, arrhythmias BP drop episodes. If there is no such problem and the valve is wide enough to let enough blood flow through it then it is not needed. Medicine can only help a patient till a limit i would recommend you to visit her cardiologist and discuss with him about possibility of preferring a medical treatment over surgery, as the cardiologist would be having access to her records and reports, he can give you a better idea about the problem. I hope this answered your question, if you have more feel free to ask. Regards. Dr.Muhammad Ahmad. General and Family Physician..
