A pilot study evaluating cutting and high-pressure balloon valvuloplasty for dysplastic pulmonary valve stenosis in 7 dogs

Transpulmonary Stent Implantation for Dysplastic Pulmonary Valve Stenosis with a Single Left Coronary Ostium and Anomalous Prepulmonary Right Coronary Artery in an English Bulldog

“…A balloon/annulus ratio of 1.2 was chosen to mimic the effects of a transpulmonary stent implant, and not for BPV, for which the ratio used is typically 1.3 to 1.5. 8 The balloon diameter selected for compression testing should have a diameter of approximately the same size to slightly larger than the pulmonary annulus. Given that the Atlas Gold selected was 1.2 times the annulus, we did not inflate the balloon fully to rated burst pressure ( Figure 2D).…”

“…Novel transcatheter therapeutics for congenital heart disease have emerged, with significant advancement over the past few decades. [7][8][9] Although the cost of transcatheter pulmonary valve implantation is a major factor for its limited use in dogs, 10 rare cases of nonvalved stent implantation have been reported as palliative therapy for dogs with PS. [11][12][13] This report describes the process of transpulmonary stent implantation in a dog with severe PS and a coronary anomaly.…”
