My father-in-law (72 yrs old) recently underwent an angiography, where 80% blockage in one artery and 70% blockage in another artery was detected. We were advised to go for an angioplasty in the arterty with 80% blockage. We are now evaluating three stents - Resolute Integrity, Xience Prime and Promus Element. Can you please help us decide which one to go for? Our cardiologist says all of them are good. But I have noted that the Promus Element is not bio-degradable. Should that affect our decision?
