Echocardiography has been one of the most significant advances in
cardiology in the past two decades. It can provide anatomic,
functional hemodynamic, and blood flow information. Conventional
transtho- racic echocardiography has limitations, particularly in
certain patients such as those with obesity, chronic lung disease,
or chest wall defor- mity, or in those where a transthoracic
approach is difficult for reasons including trauma, life support
apparat uses, and surgical dressings. There are also certain
disease states or conditions in which transtho- racic
echocardiography expectedly gives incomplete or inadequate in-
formation. Transesophageal echo cardiography has opened a unique
"new window to the heart." The immediate proximity of the esophagus
and the posterior heart permits exceptionally high resolution
images, par- ticularly of the left atrium, mitral valve, and
intraatrial septum. Addi- tionally, from the stomach (trans gastric
views), the ventricles can be dependably imaged. Transesophageal
echo cardiography presently is utilized in two environments:
intraoperatively and for outpatient examinations. Intraoperatively,
TEE is utilized to monitor cardiac function and de- tect
intracardiac air or debris, to diagnose or quantitate cardiac path-
ology, and to access operative results.
Preoperative and intraoperative echocardiography has become an
indispensable tool for guiding mitral valve surgery and has
fostered the development of many innovative surgical techniques.
Mitral valvuloplasty is now an established surgical method for the
treatment of mitral insufficiency but the success is largely
dependent on the extent of the underlying disease of the mitral
valve. The book by Dr. Ng and coauthors is an extraordinary
presentation of the relation between echocardiographic display of
mitral valve pathology and reconstructive mitral valve surgery. The
atlas provides an excellent illustrative guide to teach
echocardiographic-anatomic correlations and educates the reader on
the techniques of mitral valve repair. The quality of the
illustrations, particularly the surgical photographs is exquisite.
The book will be helpful for cardiologists and cardiac surgeons.
