My father had gone through Angiography angioplasty last saturday.Doctor MrRastogi told that it is only 30 minutes process. he took 3 hours and finally after 10 hours he surrendered and My Dear father was died that place.I would never suggest anyone to go to that hospital in future atleast for heart disease.He had made mistake and did not treated well to patient and the patient(Person having fourth Artery could servive without any angioplasty) died on the spot.try to consult other doctors before going any heart treatment because life is so important.For doctors patients are like vegetables so its ur wish whether you want to live or want to be a victim.
