The Cardiology Service at the Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania was established in 1958 and is considered the birthplace of specialty veterinary medicine. Today, the service continues this tradition by offering state-of-the-art diagnostic and treatment services aimed at improving the health and well-being of animal companions. The service offers comprehensive diagnostic services, including echocardiography, electrocardiography, radiography, angiography, and 24hr ambulatory ECG (Holter) monitoring.
The service also offers the latest minimally-invasive surgical and interventional therapies, including correction of congenital heart defects and artificial pacemaker implantation. The Cardiology Service also offers access to numerous clinical trials involving new therapies and diagnostics that are not available anywhere else in the state.
Each year, the service sees over 1,500 patients. We will work in collaboration with your family veterinarian to provide compassionate and expert healthcare for your pet.
