Shock wave lithotripsy reduces risk of stent retraction by up to 90 percent
PUNE: In our country more than half a million heart patients undergo angioplasty every year. Of these, the blockages found in the coronary artery of 90 percent of men over the age of 70 and 67 percent of women are calcium. Till now, stenting was extremely difficult to perform in these blockages and bypass surgery was the only option available to the patient, but now intravascular lithotripsy or shock wave lithotripsy technique has come up. With the help of this technique,angioplasty can be easily done in the patients who do not have the capacity to undergo bypass surgery.
What is shock wave lithotripsy?
Dr. Abhijeet Palashikar, Senior Intervention Cardiologist of Sahyadri Hospital, Pune, said that that till now it was very difficult to get stenting from the intervention in the artery with the calcified blockage because even after the stenting, there is a risk of 30 to 50 percent of its closure or the rupture of the artery. It is examined with optical coherence tomography (OCT). In this investigation, the artery can be seen with 10 times higher resolution than sonography and it can also be determined that how much calcium is broken by shock wave lithotripsy, whether the stent is open well or not. is shock wave lithotripsy?
How does technology work ?
Shock wave lithotripsy is a sonographic technique. In this, calcium is broken through a sonographic wave and a stent is inserted. This causes no damage to the artery and fine particles of calcium become part of the artery. Dr. Abhijeet explains that angioplasty with this technique takes 45 minutes to an hour and the probability of recurring blockage is only five to seven percent.
OCT test clears the condition of stenting-
Optical coherence tomography (OCT) examination makes it possible to examine in depth the amount of blockage that is coagulated in the coronary artery and how much coagulation it has in the artery. Dr. Abhijeet Palshikar stated that OCT Guided Angioplasty also reduces the chances of possible mess in stent.
