"Echocardiography is the heart of clinical cardiology" was an appropriate theme for the 15th Scientific Sessions of the American Society of Echocardiography. Care of the cardiovascular patient is constantly changing, and this meeting showcased how echocardiographic and Doppler methods continue to be critically important to detect and quantify disease, determine response to therapy, and guide clinical decision making in contemporary medicine. This highly successful five-day educational event attracted a record number of attendees and focused on disease-based clinical applications of the latest technological advances in cardiac ultrasound, including advances in diagnosis and treatment of heart failure, valvular disease, coronary disease, and congenital disease.
