Safe and Novel Sonic Boom Technology to Open Hard Blocked Arteries at BM Birla Heart Research Centre

News Desk, News Nation 360 : Occurrence of coronary artery calcification is high among patients with advanced age, chronic kidney disease, and diabetes. The percutaneous coronary intervention of heavily calcified coronary artery remains a significant challenge for interventional cardiologists. A promising new addition to the armamentarium for treatment of severely calcified lesions in the coronary and peripheral vasculature is the adaptation of lithotripsy technology for vascular calcification. Dr Anil Mishra, Consultant, Interventional cardiologist, BM Birla Heart research centre explained that an 87 years old man was admitted to BM Birla with 90 per cent blocked the left Main artery. His left artery was densely calcified. Since rotablation was difficult and has a higher complication rate we tried a standard technique of non-compliant and cutting balloon angioplasty at first, with extremely high pressure but it became impossible to open such a blockage. These calcified blocks behave like hard rocks. Even if we put stents, they do not open up well causing a very high chance of re-blockages. Such blockages are found in nearly 20% of the patients especially those who are elderly diabetic or have chronic kidney disease or have long-standing blockages or previous bypass surgery. Hence, they decided to go ahead with the Shockwave Coronary Lithotripsy, which is a major advancement over the previous techniques and used for such hard blockages since ultra-high pressure balloons or rotatory drills are complex to use and carry the risk of rupturing the artery. Such blockages can now be opened with ease and safety to give patients the best results for the long term. The sonic pressure waves are produced when performing Intravascular Lithotripsy giving them a novel safe and proven treatment option to break up the calcified plaque with potentially least risk of injury to the artery compared to other treatments. The calcium hardened structure restricts normal artery movement and makes the rigid arterial tissue resistant to traditional balloon therapies that have been designed to compress the plaque within the artery wall to restore normal blood flow. The angioplasty was successfully conducted and the patient is doing well post the procedure. He has been discharged within a couple of days from the hospital. With a hospital stay of only two days and hardly any incision or blood loss, he is back to normal life. He is delighted, and the family is relieved.
