Ever since the second edition of Echo Made Easy was published
five years back, there have been tremendous advancements
in the field of echocardiography. To name a few, three-
dimensional technique, tissue-Doppler study and myocardial-
contrast imaging have gained considerable popularity.
Nevertheless, there remains an unmet need for a simplistic
book on basic echocardiography for the uninitiated reader. It
gives me immense pleasure to present to cardiology students,
resident doctors, nurses and technicians working in cardiology
units, this vastly improved third edition of Echo Made Easy.
The initial chapters will help the readers to understand the
principles of conventional echo and color-Doppler imaging, the
various echo-windows and the normal views of cardiac
structures. The abnormalities observed in different forms of
heart disease including congenital, valvular, coronary,
hypertensive, myocardial, endocardial and pericardial diseases
have been discussed under separate sections. Due emphasis
has been laid on diagnostic pitfalls, differential diagnosis,
causative factors and clinical significance.
Those who have read the previous editions of Echo Made
Easy will definitely notice a remarkable improvement in the
layout of the book. Readers will appreciate a bewildering array
of striking figures and impressive tables. For this, I am extremely
grateful to Dr Rakesh Gupta, an expert in echocardiography of
international repute. He has been very kind and generous in
providing me with real-time images from his vast and valuable
viii Echo Made Easy
collection. I am also very thankful to M/s Jaypee Brothers
Medical Publishers (P) Ltd, New Delhi, India, who infuse life
into subsequent editions of all my books, by virtue of their
typesetting and artwork expertise. Do keep pouring with your
comments and criticism. Bouquets and brickbats are both
welcome. Bon voyage through Echo Made Easy, third edition.

Ultrasound has revolutionized clinical practice by providing the
fifth dimension to physical examination after inspection,
palpation, percussion and auscultation. Echocardiography is the
application of ultrasound for examining the heart. It is a practi-
cally useful, widely available, cost-effective and noninvasive
diagnostic tool. Usage of echo is rapidly expanding with more
and more clinicians requesting for and interpreting it to solve
vexing clinical dilemmas.
While I was preparing the manuscript of this book, many a
time two questions crossed my mind. First, is such a book really
required? And second, am I the right person to write it? At the
end of the day, I, somehow, managed to convince myself that
a precise and practical account of echocardiography is indeed
required and that an academic Physician like myself can do
justice to this highly technical subject.
The book begins with the basic principles of ultrasound and
Doppler and the clinical applications of various echo-modalities
including 2-D echo, M-mode scan, Doppler echo and color-
flow mapping. This is followed by an account of different echo-
windows and normal echo-views along with normal values and
dimensions. The echo features of various forms of heart disease
such as congenital, valvular, coronary and hypertensive
disorders are individually discussed. Due emphasis has been
laid on pitfalls in diagnosis, differentiation between seemingly
similar findings, their causation and clinical relevance. Under-
standably, figures and diagrams can never create the impact
of dynamic echo display on the video-screen. Nevertheless,
they have been especially created to leave a long-lasting visual
x Echo Made Easy
impression on the mind. In keeping with the spirit of simplicity,
difficult topics like complex congenital cardiac disease,
prosthetic heart valves and transesophageal echocardiography
have been purposely excluded.
The book is particularly meant for students of cardiology as
well as keen established clinicians wanting to know more about
echo. If I can coax some Physicians like myself to integrate
echocardiography into their day-to-day clinical practice, I will
feel genuinely elated for a mission successfully accomplished.
