This may seem a little late, but I was reviewing for the 2018 CCVTC with the 2016 version of the study guide (I bought it years ago with intent on taking test sooner). I noticed a mistake with the case regarding mitral valve reconstruction. The answer given for the question regarding CPT code selection clearly is incorrect. I was wondering if this was corrected in later editions and/or is this something I should pay attention to on the exam (as the authors of the exam wrote the study guide).
