Interventional Cardiology in Dogs and Cats

  Interventional cardiology is an advanced field of cardiology that uses sophisticated procedures and imaging techniques to provide minimally invasive therapy for a variety of cardiovascular problems.  The heart is connected to the blood vessels/vasculature of the body, pumping blood through these vessels.  When needed, these vessels allow for direct access to the heart and vasculature.  Larger vessels in the legs or neck are chosen as entry points for interventional cardiology procedures, with access aided…

Feline Hypertrophic Cardiomyopathy (HCM)

Hypertrophic Cardiomyopathy (HCM) is the most common form of heart disease in cats that results in thickening of the heart muscle, specifically the main pumping chamber of the heart (left ventricle). This thickening (called hypertrophy) can impair the relaxation of the heart and cause secondary enlargement of the top chamber on the left side of the heart (left atrium). This can lead to congestive heart failure, clot formation and even sudden death in severely affected…

Heart Murmurs in Dogs

The normal heartbeat makes a sound that corresponds to the closing of heart valves during the heart cycle.  A heart murmur, caused by turbulent blood flow within the heart or large vessels that arise from it, sounds like an abnormal whooshing or swishing sound during the heart beat cycle. This can be heard with a stethoscope and, if loud enough, can be felt as a buzzing or vibration over the heart. Careful listening with a…

Arrhythmias (Abnormal Heart Rhythms) in Dogs and Cats

  The normal pacemaker of the heart lies in the heart’s right upper chamber. This structure, known as the sinus node, normally generates the heart’s electrical impulse. This impulse is then carried through the upper chambers and reaches a structure known as the AV node. Normally, the AV node is the only electrical connection between the upper and lower chambers of the heart, so it conducts the impulse down to the pumping chambers, which then…
