Abstract

Abstract: Pulmonary artery stenosis and pulmonic stenosis are rare congenital heart diseases in domestic cats. This case describes the incidental finding of pulmonary artery stenosis in an asymptomatic cat that was originally described as pulmonic stenosis; it highlights the criteria for differentiation of the two conditions. This cat was initially diagnosed at 1.5 years with pulmonic stenosis. During a recheck at 13 years of age, the stenotic lesion was determined to be anatomically supravalvular rather than at the level of the valve. There was debate as to whether the lesion should be classified as supravalvular pulmonic stenosis, but ultimately, pulmonary artery stenosis was considered more appropriate. There are discrepancies in the literature regarding what the qualifications for these conditions are, and if supravalvular pulmonic stenosis is the appropriate terminology. The purpose of this case report is to further explore these qualifications to justify the diagnosis of pulmonary artery stenosis in this patient.
