Plain-English summary
A 3-month-old male pit bull cross was brought in because he was collapsing. The vet found serious heart issues, including a significant heart murmur and a condition called pulmonic stenosis, which was causing the heart to work too hard. After a month of medication, the dog underwent a balloon procedure to help his heart, but the next day, tests showed a tear in a heart valve and a membrane in the pulmonary artery. Fortunately, follow-up exams showed that the condition didn't worsen, and the puppy is currently doing well without any symptoms.

Abstract
A 3-month-old, 9.9 kg, male pit bull cross was referred for evaluation of collapse. A left basilar systolic heart murmur graded V/VI and a grade IV/VI right basilar systolic heart murmur were ausculted. Echocardiography showed severe pulmonic stenosis characterized by annular hypoplasia, leaflet thickening, and leaflet fusion. After 1 month of atenolol therapy, a pulmonic valve balloon valvuloplasty procedure was performed, and the intra-operative right ventricular pressure was reduced by 43%. Echocardiography, performed the following day, showed apparent rupture of a pulmonary valve leaflet and a membranous structure within the pulmonary artery consistent with a dissecting membrane. Short-term follow-up has shown no apparent progression of the pulmonary artery dissection and the patient remains free of clinical signs.
