 Iotic stenosis is a common disease 2% of population above 60 years and around 5 to 8% of population above 80 years would actually have Iotic stenosis in which the valve which is Iotic valve becomes smaller. Now these patients typically presents with you know breathing difficulty while walking they have chest pain while walking and most of the time when the doctor puts his death he realizes there is a murmur which is now present and they pick up this Iotic stenosis by doing a echocardiogram. One of the therapeutic option for this procedure will be Tavi or trans-catheter Iotic valve implantation. In this there is no opening of the chest or no opening of the heart no bypass machine. It is done like angiogram that means you go from the leg most of the time you take a small catheter and balloon the old diseased valve and like deploying a stent you deploy a new valve. So the procedure takes around 30 to 40 minutes most of the time patient can sit up just after the procedure and they can be discharged in two days. So it's important that people know about Tavi and understand that there are options other than surgery for patients with Iotic stenosis.
