 Hello, I'm Dr. Ranjan Shetty. I'm here to talk about Impella. You know, sometimes when heart is very weak, the pumping becomes very low and such patients, when we have to do a coronary intervention, that means if they have block and if we need to do angioplasty and open up the block it's difficult. They do not tolerate these procedures well because their pumping is subnormal. You know, if the normal pumping is 55 to 60, we do have patients who have less than 20% pumping. So one of the procedure which really helps them is called Impella. Now, we know heart has lots of function, but the main function of the heart is that it is a pump, which pumps the blood from the left ventricle to outside the body. So what this Impella does is, it's also a pump. So what it does is, it removes the blood from the left ventricle. Irrespective of the heart beating or no, the blood actually comes through iota and it can maintain the pumping activity. Once this happens, it's very easy for us to tackle all the blocks and we can make the procedure safe. We also use Impella in patients who come with a severe heart attack where pumping is, you know, reduced to a great extent. Impella helps us to, you know, helps, gives times for heart to recover and it is something which we use like a bridge for heart muscle to recover. So there's a role for Impella in some of the complicated heart conditions and when we use it, it makes the procedure very safe.
