Dr. Conni Wehausen, DACVECC, has been a wonderful addition to AERC. I have worked with her on many mutual patients and have nothing but positive things to say. She is always available for consultation on any case whether I end up referring the patient to her or not. She is an excellent clinician and highly skilled veterinarian, but more importantly she is compassionate and treats our patients and their owners with respect. The feedback I have received from clients has been very positive and I will continue to refer my critical and highly complex cases to her.
Dr. Michelle Rose, DVM, DACVIM (Cardiology), is a board-certified veterinary cardiologist who is dedicated to diagnosing, managing, and treating disorders of the heart and cardiovascular system.
Dr. Rose sees dogs, cats, and exotic pets that are referred to her because their primary veterinarians either suspect that these pets might have heart disease, or have already confirmed that they have heart disease and are seeking to optimize their therapy.
Dr. Rose’s number one priority is that her patients have a good quality of life at home, for as long as possible.
Another common reason that pets are referred to Dr. Rose is that their primary veterinarians detected a heart murmur (“whooshing” sound) or an arrhythmia (irregular heart rhythm) on their physical exam prior to having anesthesia performed for a dental or surgery. Understandably, both the pet owner and veterinarian will wish to know what the animal’s risk of experiencing heart complications is during the anesthesia. While there is no test that will always answer this question with 100% accuracy, the many tools available to cardiologists – echocardiography, electrocardiography, Holter monitors, and blood tests (see below) – will reveal an enormous amount of information about how safe it is to go ahead with the planned procedure.
Sometimes no medications are needed, and careful planning and extra vigilance during anesthesia are all that is required. Other times, the pet may need to be treated first to improve the cardiovascular system and help it become strong enough to withstand anesthesia. Infrequently, the advice given will be to not place the pet under anesthesia, as the risk is not worth the potential benefit.
Acquired heart disease (middle-age to late-onset) is one of the most common disorders affecting companion animals, but most pet owners are unaware that there is a problem early on. Dogs and cats with leaking heart valves, weak or abnormal heart muscle, or irregular heartbeats often act completely normal for months to years before they start to show clinical signs. The only abnormality detected might be on the pet’s physical exam by its primary veterinarian. Early detection can make a huge and important difference in the pet’s prognosis.
Some of the clinical signs of advanced heart disease are as follows:
• Labored breathing
• Rapid breathing
• Exercise intolerance, weakness
• Poor appetite
• Weight loss
• Swollen abdomen
Dr. Rose performs the following specialized procedures:
• Echocardiography – A complete ultrasound study of the heart, evaluating the four heart valves; strength and thickness of the heart muscle; the pericardium; the great veins and arteries; and the diastolic (filling) and systolic (pumping) function of the heart. An echocardiogram can also identify cardiac tumors, as well as both congenital and acquired heart disease. Dr. Rose performs 98% of her echocardiograms with the pet awake (i.e. not sedated), as this is a noninvasive and painless test. If your pet is extremely anxious and you would prefer mild sedation, this is easily accommodated for.
• Electrocardiography (ECG) – The electrical activity of the heart is evaluated from 6-12 different angles to determine whether an arrhythmia (irregularity of the heart’s rhythm) exists, and how benign or malignant the arrhythmia is.
• Holter monitors – These special monitors record the heart’s electrical activity for up to 96 hours at a time, storing every single heart beat digitally so that the heart rhythms can be evaluated closely at the conclusion of the study. Holter monitors are considered a “walking ECG” – the pet’s heart rate can be evaluated while sleeping, running, barking, eating, etc. A button can be pushed by the pet owner to mark when an unusual activity occurs, such as fainting.
• Blood tests – Various blood tests are available (NT-proBNP, cardiac troponin I) to help stage and prognosticate heart disease. Other tests, such as taurine, can document a nutritional deficiency within the heart muscle.
• Blood pressure – Cardiology technicians are often the best in the business at obtaining accurate blood pressures. Blood pressure is known to vary based on the stress level of the patient, time elapsed since medications were administered, and method used to obtain the blood pressure.
What is the difference between a board-certified cardiologist and a traveling ultrasonographer?
Board-certified cardiologists have completed four years of veterinary school, a one-year internship, and three years of a cardiology residency under the supervision of other boarded cardiologists. They are required to pass two national board exams at the end of their second and third years of residency training. They also receive specialized training in the management of cardiac disease, and are familiar and comfortable with multimodal treatment protocols that optimize the patient’s quality of life. They are highly proficient in echocardiography, and use advanced imaging modalities such as color-flow Doppler, spectral Doppler, and tissue Doppler to best diagnose a pet’s type and stage of heart disease.
Because cardiologists only see and treat heart disease all day long, they are required to be familiar with the most current veterinary literature and treatment protocols.
Dr. Rose is available for consultation on Mondays and Thursdays. She works out of the Oakdale location, and is also able to come to your veterinary clinic with her portable echocardiogram.
