Lung ultrasound for serial monitoring of Congestive Heart Failure in dogs

Area of Study: 

Purpose of Study: 

The purpose of this study is to determine whether and how lung ultrasound can be used in the diagnostic monitoring of dogs with congestive heart failure. Lung ultrasound is a new and noninvasive imaging modality that can help identify fluid in the lungs (pulmonary edema). We are attempting to determine how quickly this fluid resolves during treatment of congestive heart failure and how often lung ultrasound should be performed when monitoring patients with this disease. Lung ultrasound is faster, less stressful, and less expensive than the other tests commonly used for this purpose (chest X-rays, cardiac biomarkers).


Client Responsibilities: 

If you agree to have your animal participate in this study, the participation will occur during the current visit only (no follow-up required). For the purposes of the study, lung ultrasound and lung auscultation (listening with a stethoscope) will be performed at several timepoints during your dog’s hospitalization (within 2 hours of diagnosis; repeated every 1-3 hours for the first 6 hours of hospitalization; and then repeated every 3-6 hours until hospital discharge).

To perform lung ultrasound, your dog will be gently restrained (either standing or lying down). Some of the hair on your dog’s chest will be wetted with alcohol (no hair will be shaved) and the veterinarian will hold an ultrasound transducer up to the side of his/her chest to obtain images of your dog’s lungs. The lung ultrasound examination lasts approximately 2 minutes.

Client Benefits: 

By participating in this study, several aspects of your dog’s medical care and treatment will be provided at no cost to you. This includes your dog’s Cardiology examination fee at this visit (normally $126.00) and all lung ultrasounds performed during hospitalization (normally $46.50 for each day of hospitalization). You will continue to be responsible for all other costs associated with the normal course of treatment (including echocardiography, X-rays, bloodwork, hospitalization fees, and medication costs), the treatment of any complications that may arise, and unrelated medical conditions.
