Abstract:
Abstract Objectives: Determine whether valve morphology, pulmonary annulus
diameter, aortic/pulmonic annulus ratio, balloon-to-annulus ratio (BAR), prepulmonary
balloon valvuloplasty (PBV), Doppler gradient, and residual Doppler
gradient are independent predictors of immediate and long-term results after
PBV in dogs as in humans.
Animals, materials and methods: Retrospective study. Medical records of dogs that
underwent PBV, from January 1999 to December 2008 were reviewed. All dogs with
pre- and immediate (24 h) post-PBV echocardiographic examination were included.
126 dogs were selected. Immediate outcome was optimal when the dog survived
the PBV and Doppler gradient was 50 mmHg. Long-term outcome (1 year) was
optimal when the dog survived at least 1-year follow-up without symptoms and
Doppler gradient was 50 mmHg.
Results: Only pre-PBV Doppler gradient was identified as a significant independent
predictor of immediate results (P < 0.001; OR 0.97, CI 0.96e0.98). Pre-PBV Doppler
gradient and residual Doppler gradient were the only independent predictors of
long-term results (P ¼ 0.036; OR 0.98, CI 0.96e0.99 and P ¼ 0.005; OR 0.95, CI
0.92e0.98, respectively).
