question: Hi doctor, I am a 32 year old male weighing 60 kg and my height is 5'9". I had undergone open heart surgery 7 years back for aortic stenosis valve replacement. One day my eye got swollen and felt some dizziness. So, I went to the doctor for checkup. He told me that I had calcium deposit on aortic valve, which is already replaced valve. Now I want to know that, Is there is any option for replacement of valve again other than open heart surgery? My whole report was good in terms of cholesterol and other things the only problem was calcium deposit. If valve can be replaced through TAVR, where can I get the best treatment? Earlier I had valve replacement open heart surgery in a reputed hospital. Please provide me all information regarding this. Is there any risk in another open heart surgery or in TAVR?
