Bristol Vet Specialists has reported on the first year of its mitral transcatheter edge-to-edge repair (mTEER) programme, developed in collaboration with the Royal Veterinary College. According to the practice announcement, the teams had operated on 30 dogs since September 2025—22 at Bristol Vet Specialists and eight at the Royal Veterinary College.
The minimally invasive procedure is intended for selected dogs with severe mitral regurgitation associated with mitral valve disease. The report says almost all treated patients experienced reduced regurgitation severity, with many also showing lower diuretic requirements and improvements in owner-assessed quality of life.
The announcement cites two-year survival of 80–100% following mTEER, compared with a generally poor prognosis once congestive heart failure develops. These figures should be interpreted cautiously: they are reported in the context of a specialist clinical programme, and the announcement does not provide a full comparative trial design, case-mix adjustment or independent outcome analysis.
Industry implications
-
Advanced veterinary cardiology is expanding beyond conventional medical management
-
Specialist imaging, interventional devices and multidisciplinary surgical teams become increasingly important as procedures develop
-
Referral networks and early diagnosis of cardiac enlargement may influence whether eligible patients reach specialist centres in time
