Development of three-dimensional cardiac models from computed tomography angiography.

Three-dimensional (3D) modeling and printing is an emerging technology in veterinary cardiovascular medicine allowing the fabrication of anatomically correct patient-specific models. These patient-specific models can be used for a wide range of purposes including medical teaching, assessment of cardiac function and movement of valve leaflets, design and assessment of devices created for interventional procedures, and pre-surgical planning [1-3]. Additionally, these 3D models can facilitate communication between the clinical team and the patient's owner.

Comparison of echocardiographic measurements and cardiac biomarkers in healthy dogs eating nontraditional or traditional diets.

Background: There has been a recent association between nontraditional diets and development of diet-associated dilated cardiomyopathy (DCM) in dogs.

Hypothesis/objectives: To compare echocardiographic measurements and cardiac biomarkers between healthy dogs eating nontraditional vs traditional diets. We hypothesized that dogs eating nontraditional diets would have lower measures of systolic myocardial performance compared to dogs eating traditional diets.

Echocardiographic and electrocardiographic effects of atenolol versus sotalol in dogs with severe subaortic stenosis.

Background: Subaortic stenosis (SAS) is a commonly diagnosed canine congenital cardiac defect, with severe forms of carrying a poor long-term prognosis. To date, an effective treatment strategy has not been developed in veterinary medicine. This study sought to determine if sotalol, a class III antiarrhythmic, may have salient echocardiographic and antiarrhythmic benefits for medical management for dogs affected with severe SAS.

Retrospective evaluation of hypertrophic cardiomyopathy in 68 dogs.

Background: There is a lack of clinical data on hypertrophic cardiomyopathy (HCM) in dogs.

Hypothesis/objectives: To investigate signalment, clinical signs, diagnostic findings, and survival in dogs with HCM.

Animals: Sixty-eight client-owned dogs.

Dynamic Obstruction of an Anomalous Cavoazygos Vessel Associated with Interrupted Caudal Vena Cava in a Boxer Dog.

• A young boxer dog presented for intermittent weakness associated with exercise. • Dynamic physical exam findings and echocardiographic study were dependent on recumbency. • A diagnosis of interrupted caudal vena cava was made by computed tomography.
