There are numerous indications for ultrasonography. The information obtained during a comprehensive examination can help narrow the differential list and can often rule out disease processes. When ultrasound is used in combination with needle aspirate and/or biopsy techniques, a definitive diagnosis can often be obtained.

Pulmonary Arterial Hypertension
- 30-40% of ALL dogs with CVD develop Pulmonary Arterial Hypertension.
- Pulmonary Arterial Hypertension affects dogs with chronic airway and lung disease, chronic degenerative valve disease (CVD), heartworm disease, and other diseases such as Cushings that can lead to a hypercoagulable state and pulmonary thromboemboli.
- Symptoms such as coughing, exercise intolerance and collapse and can mimic other conditions. Symptoms may not occur until late into the disease progression
Chronic Degenerative Valvular Disease
- CVD remains the most common heart disease of small and medium sized dogs
- Using echocardiography to measure precise metrics allows for the determination of when to start pimobendan based on the 2016 EPIC study.
- Starting pimobendan too early is strongly associated with adverse myocardial and functional effects including myocardial hemorrhage and increased mitral regurgitation
- Starting pimobendan as indicated based on the criteria from the EPIC study (LA:AO ratio, normalized left ventricular internal diameter) is safe and well-tolerated and can significantly extend a patient’s life expectancy
