2016 ACVIM Forum Research Abstract Program

Medical records were reviewed for French and English Bulldogs presented to Oregon State University for heart murmur evaluation or imaging prior to balloon valvuloplasty (BVP). Dogs were included if they had severe PS (pressure gradient >80 mmHg estimated via echocardiography) and confirmation of their coronary artery anatomy by either angiography or computed tomography (CT). Echocardiographic, angiographic, and CT images were reviewed. The pulmonic annulus (PA), aortic annulus (Ao), PA:Ao ratio, valvular anatomy, and coronary anatomy were assessed on each imaging modality by three observers (CS, KS, DDS) and averaged. Tricuspid regurgitation (TR) was assessed on echocardiographic and angiographic studies. Breed medians or means were compared by Mann-Whitney U test or unpaired t-tests as indicated. In the dogs that had both CT and angiographic studies, values were compared by paired t-tests.
