I am not generally a fan of case-based discussion books, since it often seems forced and necessarily limited to only certain aspects of a given disease. This, however, is an exception to that generality. The chapters begin with one or two clinical vignettes, and then proceed to a general overview of the given topic, ending with tying the high points of the case into the preceding discussion. What is done well here is that the discussion is broader than the initial case requires, and the cases are well chosen to reflect classic findings.
The chapters cover:
1 Secundum atrial septal defect
2 Atrioventricular septal defect
3 Pulmonary stenosis/RVOT obstruction
4 Ventricular septal defect
5 Pulmonary arterial hypertension in Eisenmenger syndrome
6 Congenitally corrected transposition of the great arteries
7 Left ventricular outflow tract obstruction
8 Coarctation of the aorta and aortic disease
9 Transposition of the great arteries after a Mustard atrial switch procedure
10 Tetrology of Fallot
11 Single ventricle physiology
12 Ebstein's anomaly
13 Imaging in adult congenital heart disease
14 The chest x-ray in adult congenital heart disease
15 Arrhythmias in congenital heart disease
16 Pregnancy and contraception
Each chapter has a different author, and a slightly different writing style, but overall Dr. Warnes has done a good job as editor in keeping things uniform. I bought this book after hearing her lectures at the Mayo Board Review Course, and this is an excellent expansion of those, and includes a lot of information that was not covered in-depth in the Mayo review book. Compared to Braunwald, this is probably only slightly more information, and all the pictures here are in black and white, so it lacks color Doppler echo frames. But I found this easier to read than Braunwald.
For the general cardiology boards, this is more than you need to know. For clinical practice I have found it immensely helpful as I start to see these patients more. While probably not necessary if you have Braunwald, it is certainly easier to read and the case-based format means that salient points on imaging and physical exam are organized under the topic at hand, which makes it easier to use a a quick reference.
Highly recommended.
