Echocardiography (ECHO) is an advanced, non-invasive imaging technique that uses ultrasound waves to visualize the heart’s structure and function in real time. It allows veterinarians to assess heart valves, chambers, wall motion, and detect congenital defects or fluid accumulation. ECHO is critical for diagnosing heart diseases like cardiomyopathy, valve disorders, and pericardial effusion. It’s a vital diagnostic step for pets showing signs of cough, breathing difficulty, or fatigue, offering precise information for tailored cardiac treatment plans.
