A small number of dogs with patent ductus arteriosus (PDA) have right-to-left flow of blood through the ductus, leading to polycythemia and clinical signs associated with hyperviscosity. Three dogs with right-to-left-shunting PDA are described. Treatment consisted solely of phlebotomy, performed on ...

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...

Lupines (Lupinus albus) collected at Ile D'Orleans and Emil Lods Seed Farm of Macdonald College in southern Quebec showed reddish brown lesions on the lower stems. Lesions originated from petiole scars and contained concentric rings of brown-black pycnidia. Similar lesions were observed on mature po...

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...

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...

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...

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....

An 11-month-old, female Scottish terrier was presented with a history of a heart murmur. The electrocardiogram showed signs of left ventricular enlargement, and radiography confirmed generalized cardiomegaly. Echocardiography revealed four equally sized aortic valve cusps. A ventricular septal defec...

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: Ventricular tachyarrhythmias occur in association with cardiac and extracardiac disorders in many species of animals, but information identifying concurrent disorders in cats with such arrhythmias is scarce.Methods: We investigated coexisting diseases by retrospectively evaluating medica...

The well recognized cardiac effects of severe hyperkalemia include progressive rhythm and conduction disturbances such as bradycardia, spiked and narrow T waves, widening QRS complex, widening and flattening P wave, disappearance of the P wave, and cardiac arrest. Paradoxically, a heart rate greater...

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...

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...

Objective—To determine the prevalence of various radiographic findings for dogs with cardiac tamponade (CT) attributable to pericardial effusion (PE) and to determine the sensitivity and specificity of such findings for identification of affected dogs. Design—Retrospective, randomized, blinded,...

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...

BACKGROUND: Cardiac disease has the potential to alter platelet function in dogs. Evaluation of platelet function using the PFA-100 analyzer in dogs of multiple breeds and with a broad range of cardiac conditions would help clarify the effect of cardiac disease on platelets. OBJECTIVES: The objectiv...

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....
