January 2007 Dr Crisco implanted two Cordis chemical treated stents; one in a two old by-pass vein. Six months, June 2007 both stents failed and I live day to day with no recourse. One doctor asked why he did not re-0pen the vein and place a teflon stent. Another doctor axked whey Dr Crisco did not implant a teflon stent to begin with. I was told they almost never fail. Dr Crisco is no longer with Northside Cardiology, I am told.
