Transvalvular pulmonary stent angioplasty for palliation of severe pulmonic stenosis in two cats.

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.
