Oh yes, definitely seeing a cardiologist--the one who performed the angiogram (and whom I've been seeing for at least 3 yrs) and most likely another, to get a second opinion. I have been researching, and my PCP and a doctor friend both have told me that failures like this are not unusual, tho the bypasses may have been put in places that are more difficult to find. I'm just shocked to find that possible all 5 have failed in 3.5 years.
