• Veterinary Echocardiography, Second Edition is a fully revised version of the classic reference for ultrasound of the heart, covering two-dimensional, M-mode, and Doppler examinations for both small and large animal domestic species. Written by a leading authority in veterinary echocardiography, the book offers detailed guidelines for obtaining and interpreting diagnostic echocardiograms in domestic species. Now thoroughly updated to address advances in technology, including better transducers, tissue harmonic imaging, better color flow mapping, and color and spectral tissue Doppler imaging, this second edition provides an authoritative, comprehensive resource for echocardiographers of all levels of experience.

    The Second Edition has been restructured to be more user-friendly, with chapters on acquired and congenital heart diseases broken down into shorter disease-specific chapters. Key changes include the addition of normal tissue Doppler technique, as well as five new appendices, covering topics such as normal reference ranges and an exam checklist. Veterinary Echocardiography, Second Edition builds on the success of the previous edition to provide complete information on obtaining echocardiograms in veterinary medicine.
