 In the last year, Bibi's team had a 0% stroke rate post-procedure. According to Qureshi, that is much lower than a national average of 5% to 7%. That puts Bibi in the top 10% nationally. Other risks outside of stroke include bleeding, which is a 5% to 10% national rate with Bibi at less than 3%. And another risk is the need for a pacemaker, which nationally is at 7% to 10%. But at Bibi, it's less than 3%. Joe Irzari, Delaware Public Media.
