This book consists of five tests on perioperative transesophageal echocardiography, in preparation for the National Boards in Echocardiography for cardiac anesthesiologists. Each test is divided into a video section and a written test section, with accompanying answers and brief explanations, as well as references to standard echo textbooks that provide some more in depth discussion of each topic. I thought that the written test questions were quite good, although too much reliance on Sidney Edelman's ultrasound physics book for my taste (lots of wrote memorization without good explanations or thinking required). Unfortunately, I cannot comment on the video half of this book, as the DVD does not work on a Mac, despite the publisher's claim that it will work on OS X 10.2 or above. This is a significant and misleading claim, as half of the benefit of this book is lost to Mac users. This omission could be dismissed if this were the year 2000, but in 2010 when everyone seems to have a Macbook, it is inexcusable.
