Plain-English summary
Two cats with severe breathing problems due to a narrowed pulmonary valve (pulmonic stenosis) underwent a special procedure called transvalvular pulmonary stent angioplasty to help improve their condition. One cat had some immediate issues after surgery, including fluid in the lungs, but the other cat recovered without complications. Both cats showed good results in the weeks following the procedure. This treatment offers a new option for cats that can't have the usual balloon procedure to relieve the blockage.

Abstract
Transvalvular pulmonic stent angioplasty has been described in dogs with severe pulmonic stenosis, when balloon valvuloplasty is not indicated or possible. We report two cats that underwent stent placement across the stenotic pulmonary valve for similar indications. Both cases had good short- to medium-term outcomes. One cat experienced immediate postoperative complications in the form of pulmonary edema, while the other cat had no observed complications. Pulmonic stent angioplasty has not been previously reported in cats. This report demonstrates a possible alternative intervention in cats with severe pulmonic stenosis where balloon valvuloplasty is not indicated or inadequate for palliation of the obstruction.
