When a bypass or angioplasty is recommended?

At IPC we give honest medical opinion, depending on the physical condition of the patient various diagnostic test reports and angiography we do patient selection for our non-surgical treatment. However in certain critical cases if bypass or angioplasty is essential we definitely give patients our opinion for the same. However as per our practice in last ten years with over 15000 consultations 90% of the patients can be treated without surgeries.
