Why did my father's angioplasty fail?
My father was going to have an angioplasty, but it actually failed and the surgeons changed the procedure to a bypass. What are the possible reasons for the surgery failing?

If the blockages are at too many locations or are very long and tight , stents are not effective and bypass surgery is the best option.

Not sure what you meant by failed angioplasty. The cardiologist usually places stents not due to isolated angioplasty. If it failed, then usually emergency surgery is required by a cardiac surgeon who does bypass.
Probably catheter perforated the artery. Or could not pass beyond the blockage. Or developed hemodynamic problems.
