Get to Know our CVCA Louisville Doctor, Team Leader and Support Staff 

 

CVCA Cardiac Care for Pets, along with Dr. Sarah Bell, opened our Louisville, KY location inside of  BluePearl Veterinary Hospital in December 2017.

When our company started in 1987, we wanted to build the best business model to support our clients, patients and referring veterinarians.  Today, all of CVCA’s locations are located inside different 24 hour emergency and referral practices, allowing our clients easy access to emergency and specialty care. We enjoy collaborating with all of the different groups that we share a hospital with to provide comprehensive care for our clients.

Our team is committed to providing the best client service, experience and the highest level of patient care for each and every patient. We hope you enjoy getting to know a little more about  our CVCA Louisville staff!

Sarah E. Bell, DVM, MS, Diplomate, ACVIM (Cardiology) 

Board-certified veterinary cardiologist

Dr. Sarah Bell has family roots in the Lexington area.  She graduated from the University of Georgia College of Veterinary Medicine and completed a rotating internship at North Carolina State University the following year.  She then decided to head North to Pittsburgh, PA to practice emergency medicine before deciding to pursue a residency in Cardiology. Dr. Bell completed her residency at the University of Missouri and achieved Diplomate status with the American College of Veterinary Internal Medicine (Cardiology). 

During her free time, Dr. Bell enjoys cooking and visiting great restaurants, reading and traveling with her husband.  She also enjoys spending time with her two dogs, two cats, and her husband.

  • Alissa, Team LeaderAlissa calls Louisville home for the past 5+ years.  She began her career in the veterinary field in 2012 working in a primary care veterinarian office as a veterinary assistant and in a few years worked her way up to a practice manager within the field.
  • Jennifer, Veterinary AssistantJennifer is a Louisville native. She has over 13+ years of experience in the veterinary field. Outside of work, she enjoys dancing, crafts, spending time with her three dogs and her family.

The Vertebral Heart Scale

By: Gina Pasieka, DVM, Diplomate, ACVIM (Cardiology)

CVCA Leesburg, VA location 

 

The Vertebral Heart Scale (VHS) system was developed as a means of evaluating radiographic cardiac silhouette size by indexing heart size to body size using thoracic vertebrae as units of measure. Originally described by Dr. Buchanan, et al in 1991 for the use in dogs, it has since been substantiated in cats, ferrets and other exotic species. It is a quick diagnostic measurement that can be easily added to your daily practice.

How Can We Use VHS?

-VHS can be a useful tool when combined with history and physical exam findings to increase suspicion for the presence of heart disease or to monitor for progression over time. We know that Cavaliers with a VHS >12, with a sudden increased VHS rate of change, were diagnosed with CHF within a 9 month period.

-A VHS >9.3 was found to be highly specific for the presence of CHF in cats with dyspnea. The same study also determined that dyspneic cats with a VHS <8.0 were unlikely to be in heart failure.

-Both the PROTECT (treatment of preclinical DCM) and EPIC (treatment of preclinical MR disease) studies utilized an increased VHS as part of the criteria in determining the appropriate time to start Pimobendan.

Calculating Vertebral Heart Scale

  1. Preferentially use a right lateral thoracic radiograph with T4-T12 vertebra clearly visible
  2. Take the long axis measurement measuring from the carina of the mainstem bronchus to the apex of the cardiac silhouette
  3. Take the short axis measurement at the widest part of the cardiac silhouette perpendicular to the long axis measurement.  For serial radiographic VHS comparison, it is often prudent to select an anatomic landmark for repeatability.  The approximate ventral aspect of the caudal vena cava is often chosen as this specific landmark.
  4. Transfer both the long and short axis measurements separately starting at the cranial edge of T4 and count the number of vertebrae that fall within the caliper points
  5. Add the two measurements: VHS = W + L

Known Breed Normals

While the initial study determined normal VHS in dogs to be 8.5-10.7, other studies have shown some breed variations.  You will note that some breed normals lie well outside the originally documented “normal” VHS.

Other Factors Affecting VHS  

  • Some studies have shown a very mild increase in VHS when measuring from the right vs. left lateral radiographs. Consider using the same projection when doing serial monitoring.
  • Hemivertebrae could alter the measurement resulting in Bulldogs having higher VHS.
  • There is an association between higher VHS and increased body condition scores
  • Pericardial effusion in dogs was associated with VHS > 12, but it should also be associated with an increase in sphericity.
  • Chronic moderate to severe anemia in both dogs and cats results in compensatory volume overload with an associated increase in VHS.
  • Studies have shown normal VHS in puppies over 3 months of age while kittens maintain a higher VHS until 9 months of age.
