With 62 chapters provided by 78 authors, Cardiology Secrets is subdivided into seven sections, including “General Examination,” “Diagnostic Procedures,” “Valvular Heart Disease,” and so on. Using a consistent question-and-answer format, the breadth of clinical cardiology is presented. The bibliographies at the end of each chapter clearly do not aim to be complete, but are adequate. The tables and figures are excellent and are reminiscent of the differential diagnostic algorithms taught at clinical rounds and used in everyday practice. The illustrations are well reproduced, focused on the subject at hand, and enhance the teaching points being made. %As in any multiauthored text, there can be some variation in the quality and consistency in the information presented. Chapter 42, “Preoperative Evaluation for Cardiac Risk,” makes a common, and all-too-often difficult, clinical decision making process both understandable and rational. On the other hand, the algorithm for supraventricular tachycardia in the chapter of the same name is needlessly incomplete. The classic logic tree published by Bar and colleagues in 1984 in the American Journal of Cardiology for the ECG diagnosis of supraventricular tachycardia would have been a better choice. %Cardiology Secrets is a text that all who are interested in cardiovascular disease, regardless of training level, will want to own. The format allows for quick referral, stimulation of lively discussion and, ultimately, learning.
