 Dr. Ranjan Shetty, Interventional Cardiologist in Manipal Hospital, Bangalore. Iotic stenosis is one of the very common valve related problems. You know heart as muscle, heart as blood vessels, heart also has cardiac valves. So in elderly it is known these valves become smaller and that's called stenosis. And Iotic valve is one of the common valves which is involved. If you look at the population statistics around 5-10% of people above 60 would have some chain in Iotic valve and around 1% of them would have severe Iotic stenosis. And at age of 80 this number is likely to rise to 2-5% that means significant number of elderly would have Iotic stenosis. Now this reduces exertional problem that means when they walk they feel breathless and when they also feel chest pain and sometimes they also lose consciousness. In elderly these symptoms are neglected thinking that this is age related but some of them could actually be having a disease called Iotic stenosis.
