Services For Breeders

Dr. Kienle is a Diplomate of the American College of Veterinary Internal Medicine, sub-specialty of Cardiology (board certified) and is qualified to perform advanced pre-breeding screening exams. Pre-breeding screening exams can be scheduled as individual screenings (either at your local clinic or at one of our locations), as health clinics at breed shows or as private group clinics. There are minimum number requirements for breed shows and group clinics.


All certifications are carried out using the standards established by the ACVIM and and the Orthopedic Foundation for Animals(OFA). Two programs are available - The Congenital Cardiac Exam and the Advanced Cardiac exam. Which exam is appropriate is determined by breed organizations and the Canine Health Information Center (CHIC). Recommendations for selected breeds can be found here.

Congenital Cardiac Database: This program allows any veterinarian to perform the exam. The certification number will designate whether the exam was done by a cardiologist, a non-cardiologist specialist, or a general practitioner. Based on the current OFA standards, breed standards, and individual patient findings, either a physical examination alone or a physical examination and a focused echocardiogram will be performed. The dog must be older than 12 months of age for certification. Prelimenary certifications can be done in younger dogs.

Advanced Cardiac Database: This exam can be used to screen for congenital heart disease or adult-onset heart disease. This exam requires an auscultation and a focused echocadiogram in all patients and can only be performed by a board certified cardiologist. Holter monitoring is also required in selected breeds. Screening for congenital heart disease requires only one examination after 12 months of age. Screening for acquired cardiac disease requires annual exams. In selected breeds an annual Holter monitor, performed within 3 months of the echocardiogram, will also be required.

Pre-breeding screenings are also available for cats. Screening exams in cats will require a focused echocardiogram to evaluate for occult hypertrophic cardiomyopathy (HCM). Screening exams in cats are not (yet) registered through the OFA. Many breed groups use unique non-standardized forms without a formal registration process. There are currently two registries available for HCM in cats. PawPeds is a European registry and the Veterinary Cardiovascular Society is a UK registry. There are currently no official US registries for HCM or other cardiovascular disease in cats. The ACVIM and the OFA are currently in a collaborative effort to provide a US registry for HCM screening in cats.

Screening Forms

UPDATE 04/01/2016- New forms are required for the OFA Advanced Cardiac Database. These are only available on-site as they are triplicate carbon-copy forms. The Congenital Cardiac Database forms are no longer valid for board-certified cardiologist clearances. The legacy forms will be accepted for non-cardiologist clearances. Dr. Kienle will have the new OFA ACA forms available at screening events.
