  • Immediately after surgery, all dogs were paraplegic with pelvic limb neurologic dysfunction consistent with myelopathy affecting the L4 through caudal spinal cord segments. (avma.org)
  • This blood is forced through the mitral valve into the lower-left chamber (the left ventricle)-with the mitral valve sealing off to stop the backflow of blood. (wikidoc.org)
  • Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation. (bvsalud.org)
