Article Synopsis
- A seven-year-old Labrador Retriever, previously fitted with a transvenous pacemaker for atrial issues, was brought in for emergency treatment due to suspected pacemaker failure after five years.
- Upon examination, the dog exhibited a very low heart rate and tests revealed no normal or paced heart activity, confirming a malfunction in the pacemaker's lead.
- After finding a fractured and excessively coiled lead via X-rays, the veterinarians opted to install a new epicardial pacing system, and while the dog had no immediate complications post-surgery, it eventually needed increased cardiac treatment and was euthanized two years later.
Background: Pimobendan is an important therapy for dogs with myxomatous mitral valve disease (MMVD). The pharmacokinetics are reported in healthy dogs but not in dogs with heart disease.
Hypothesis/objectives: To determine if dog characteristics such as age, breed, body condition score, ACVIM stage of heart disease or biochemical laboratory value alter the pharmacokinetics of orally administered pimobendan and its metabolite in a cohort of dogs with naturally occurring MMVD.
Background: Echocardiographic indices of the inferior vena cava have been associated with elevated right atrial pressures in humans.
Hypothesis/objectives: Describe caudal vena caval (CVC) sonographic dimensions in healthy cats compared to cats with cardiogenic cavitary effusion (CCE), cardiogenic pulmonary edema (CPE), or non-cardiac causes of cavitary effusion (NCE).
Animals: 30 healthy control cats and 52 client-owned cats with CCE, CPE, or NCE examined at two university hospitals.
Introduction: Dilated cardiomyopathy (DCM) in dogs has been associated with feeding of grain-free (GF), legume-rich diets. Some dogs with presumed diet-associated DCM have shown improved myocardial function and clinical outcomes following a change in diet and standard medical therapy.
Hypothesis: Prior GF (pGF) diet influences reverse cardiac remodeling and clinical outcomes in dogs with DCM and congestive heart failure (CHF).
