Insights

A middle-aged cat with hypertrophic cardiomyopathy (HCM) developed acute mesenteric ischemia, leading to vomiting, diarrhea, and limb weakness. CT scans revealed widespread thrombi and necrotic bowel, highlighting a severe complication of HCM in felines.

Area of Science:

  • Veterinary Medicine
  • Cardiology
  • Diagnostic Imaging

Background:

  • Hypertrophic cardiomyopathy (HCM) is a common cardiac disease in cats.
  • Thromboembolic events are a known, severe complication of feline HCM.
  • Mesenteric ischemia, though less common, can occur secondary to thromboembolism.

Observation:

  • A middle-aged cat presented with acute gastrointestinal signs and pelvic limb paresis.
  • Radiography revealed cardiomegaly, pulmonary infiltration, and portal venous gas.
  • Computed Tomography (CT) identified extensive thrombi and signs of necrotic bowel.

Findings:

  • Hypertrophic cardiomyopathy (HCM) was confirmed as the underlying cardiac condition.
  • CT imaging demonstrated thrombi in the aorta, mesenteric, renal arteries, and caudal vena cava.
  • Characteristic CT findings of dilated, gas-filled bowel with thin walls indicated acute mesenteric ischemia.

Implications:

  • This case highlights the critical link between feline hypertrophic cardiomyopathy and acute mesenteric ischemia.
  • CT imaging is crucial for diagnosing thromboembolic complications and associated visceral ischemia.
  • Early recognition and understanding of these complications are vital for feline patient management and prognosis.

Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
