OBJECTIVE: To assess the frequency of heart murmurs in overtly healthy cats. DESIGN: Prospective study. SAMPLE POPULATION: 103 healthy domestic cats. PROCEDURE: Background information and physical characteristics were assessed in cats that were candidates for blood donation during an 8-month period....

Background Predicting subaortic stenosis (SAS) in adult Golden Retriever dogs (GRs) by evaluating them as puppies is hampered by the progressive expression of the SAS phenotype in youth. In some children who develop SAS as adults, an abnormal aortoseptal angle (AoSA) precedes development of stenosis...

OBJECTIVE: To determine signalment, clinical signs, diagnostic findings, treatment, and outcome for cats with atrial fibrillation (AF). DESIGN: Retrospective study. ANIMALS: 50 cats. PROCEDURE: Medical records of cats that met criteria for a diagnosis of AF (ECG consisting of at least 2 leads, clear...

Blastomycosis was diagnosed in 6 dogs living in New York state. To our knowledge, blastomycosis has not been previously reported in dogs in this area, and maps that indicate the prevalence of blastomycosis in North America often partially or completely exclude the state of New York. Environmental ch...

A 1 year old intact female Labrador retriever dog presented for evaluation of syncope caused by severe bradycardia. Advanced atrioventricular block was diagnosed. A mass infiltrating the interventricular septum and the tricuspid annulus was identified with echocardiography. Histopathological evaluat...

Severe heart disease may cause hypotension and hypoperfusion, and ultimately circulation may cease altogether. These two clinical syndromes are cardiogenic shock and cardiac arrest, respectively. This review summarizes the causes and clinical features of each, and describes the treatment options ava...

L-Carnitine is an amino acid derivative required for the beta -oxidation of long-chain fatty acids, a process necessary for deriving energy from fat. Carnitine deficiency has been shown to cause dilated cardiomyopathy in a small population of dogs, and effects of carnitine deficiency on other tissue...

Objective- To evaluate the usefulness of Doppler-derived peak flow velocity through the left ventricular outflow tract (LVOT Vmax) and effective orifice area indexed to body surface area (EOAi) in puppies to predict development of subaortic stenosis (SAS) in the same dogs as adults. Design- Prospec...

Background A 10 week-old intact female German shepherd dog was examined because of a heart murmur.; Methods An echocardiogram revealed an extracardiac left-to-right shunt. An angiogram identified shunting between the aorta and the pulmonary artery in an unusual location.; Results Thoracotomy was per...

Because urinary bladder rupture can be life threatening, a simple, safe technique for evaluating patients is desirable. Current diagnostic protocols involve radiographic imaging, but ultrasound-based contrast techniques have not been methodically evaluated in veterinary patients with urologic trauma...

The asymmetric shape of the heart, small acoustic window, and range of interindividual variation in normal and abnormal states all can limit the extent of echocardiographic studies in small animal medicine. Beyond these uncontrollable variables, however, there are a number of additional potentially ...

BACKGROUND: The platelet function analyzer (PFA)-100 is a point-of-care instrument previously evaluated in humans and dogs. In both species, artificially prolonged platelet closure time (CT) occurs with anemia. Reliability of the analyzer in dogs becomes a concern when the HCT is between 0.25 and 0....

BACKGROUND Myocardial fibrosis is a hallmark of hypertrophic cardiomyopathy (HCM). Human patients with HCM have high serum concentrations of biomarkers of collagen synthesis, indicating a profibrotic state. This abnormality exists in sarcomere mutation carriers both with and without overt left ventr...
