In this video, Prof (Dr) Saumitra Ray, Joint Secretary, Cardiological Society of India, Kolkata, will talk about the interventional cardiology procedure rate of less than 200 per year and CSI guidelines on their treatment. He says that more than 200 cases per year should be registered in any hospital and an interventional cardiologist should monitor the cases properly. If it is less than 200, it should be supervised to ensure patient safety. He will further talk about how to choose stents. It should be 80% on evidence based science and 20% on socioeconomic grounds.
