The Medtronic Reveal LINQTM ICM is a viable option for cutaneous cardiac monitoring in dogs for up to 5 days. Veterinary parameters for auto-activation of the device should be programmed at the upper and lower limits of the auto-activated parameters to reduce the number of incorrectly labelled recordings and all recordings should be reviewed by a veterinarian familiar with normal cardiac rhythms. Subaortic stenosis (SAS) is the most common congenital cardiac defect identified in dogs. While it is not difficult to diagnose severe forms of this disease, treatment and decisions on when to consider interventional therapy remain a challenge. It has been suggested that SAS, in some breeds, may be related to an abnormally steep aortoseptal angle (AoSA) -a quality which may limit efficacy of ballooning methods. If an abnormally steep AoSA contributes to SAS and is not remedied by ballooning, it is possible that the magnitude of the AoSA may serve as a useful criterion for determining which dogs will respond better to balloon valvuloplasty and are therefore better candidates for the procedure.
