In this episode, host Alyssa Watson, DVM, talks with Amara Estrada, DVM, DACVIM (Cardiology), about her recent Clinician’s Brief article, “Measuring Vertebral Left Atrial Size in Dogs.” Dr. Estrada reviews the 2019 consensus guidelines in sharing the history of this new measuring tool. She then explains how to use it, along with the VHS, to screen for cardiomegaly and determine which dogs should be on pimobendan and which really shouldn’t.

Key Takeaways

  • Left atrial (LA) enlargement is often the first structural change in dogs with MMVD.
  • Structural changes are what distinguish stage B1 from stage B2 cases.
  • B2 cases benefit from pimobendan therapy; B1 cases do not.
  • The VLAS screens for LA enlargement in assessing cases as B1 vs. B2.
  • It is performed on a right lateral radiograph in a similar fashion to a VHS.
  • Both VLAS and VHS should be used to screen for cardiomegaly.
