Echocardiography is basically defined as a sonogram of heart. This book is a compilation of research works by international researchers; some of them specializing in imaging science in their clinical orientation, and others, representatives from academic medical centers. The book has been structured and written with such simplicity that it will be understandable to readers with basic knowledge of echocardiography and will also be stimulating and informative to experts and researchers in the field of echocardiography. This book targets readers involved in cardiology during their basic echocardiography rotation, internal medicine, radiology and emergency medicine and also to specialists in echocardiography. Over the last few decades, the rate of technological developments has grown exceptionally, resulting in new techniques and improved echocardiographic imaging. The authors of this book have emphasized on presenting the most advanced techniques useful in today's research and in daily clinical practice. These advanced techniques are applied in the detection of different cardiac pathologies in patients contributing to their clinical decisions, follow-up and outcome predictions. Along with the advanced techniques, this book explicates several special pathologies with respect to the functions of echocardiography.
