Itwas performed by Dr. P Lalin February, 1998 at Metro Heart Institute Noida (Delhi NCR) ona 48 years old patient who suffered heart attack and his main artery LAD was loaded with blood clot. A probe was attached to the ultrasound device through the guiding catheter. After the probe was brought up to the sight of the clot, ultrasound energy was delivered for 5 minutes and the blood clot was broken into fine particles which dissolved in the blood stream. It was thought to be helpful in patient having peptic ulcers and stroke where the blood thinner if given to resolve the blood clot can cause bleeding.
