摘要: Combined cutting balloon and high-pressure dilation was performed in a dog with double-chambered right ventricle severe infundibular stenosis of the ventricular outflow tract. The peak systolic pressure gradient across decreased by 65% after (from 187 mmHg before to 66 mmHg after) affirming intervention as successful. However, early re-stenosis occurred within 3 months leading exercise intolerance, exercise-induced syncope, right-sided congestive heart failure. Cutting followed provided temporary but not long-term relief obstruction this dog.
