Event Description

Received e-mail dated 31 aug 2016 from a patient: hello, my name is (b)(6) and i had an aortic heart valve replaced with one of yours on (b)(6) 2011 at (b)(6).It only lasted 4 years, i was in terrible shape last year.You see my doctor used on that was under sized, my bsa is 2.2 and he used a size 23.It leaked from the very first day, but they mislead and assured me that it was fine.So like i said last year the pressure got to it and i damn near died.They were hacks and tried to plug it cover up their mistake.Those blew out too.And i opted to go to (b)(6), they too noted the valve size was too small.They used an on-x 27-29, 4-6 sizes bigger i believe than yours.I hope it was not your chart that confused them, i am very unhappy with what happened.And paying for 3 surgeries when 1 should have been all i needed.Info from patient tracking as of 07 sep 2016: our record shows that the patient has a s5-023 sn # (b)(4) implanted on (b)(6) 2011 at (b)(6).Patient male dob (b)(6).
