This case centers on a one year old, fe1nale spayed, Newfoundland that was diagnosed with pulmonic stenosis. Based on her overall size and diameter of the stenotic lesion, a double balloon valvuloplasty was considered her best treatment option. The procedure consisted of performing measurements of the diameter of the stenotic lesion, venous cut-downs for catheter placements, and balloon inflations to tear the fused pulmonic valve leaflets. Measurements and location of the stenotic lesion vvere performed via transthoracic echocardiography, transcsophageal echocardiography and angiogram. Pressure and angiographic catheters were advanced via the jugular vein and balloon catheters ,were advanced simultaneously via both femoral veins. Fluoroscopy was used to aid the visualization of the balloon inflation. Once the pulmonic leaflets were torn, the pressure gradient across the stenotic lesion was re-measured. Intraoperative success was defined as >50􀇰{, decrease in the pressure gradient across the stenotic lesion
