For more than 50 years, Feigenbaum’s Echocardiography has been a trusted resource for echocardiographers, fellows, clinicians, and sonographers, offering authoritative guidance on pertinent physics, technology, clinical applications, and new developments in the field. The fully revised Ninth Edition, by Drs. Troy M. LaBounty and Melissa A. Daubert, continues the tradition of excellence as a must-have text for practitioners who use echocardiographic methods to care for and manage patients, with a focus on evidence-based applications, emerging technologies, and the rapidly growing field of interventional echocardiography.
