Balloon valvuloplasty for severe subaortic stenosis in a Pomeranian dog

Abstract

A nine-month-old Pomeranian dog with exercise intolerance and syncope was presented. The dog was depressed with grade 4 systolic murmur on cardiac auscultation. Based on cardiac examination, the dog was diagnosed with severe subaortic stenosis with involvement of the anterior mitral valve. β-blocker administration was initiated and clinical signs were improved, but not fully resolved. Balloon valvuloplasty was performed and the dog survived for nearly one year without clinical sign and the cardiac troponin I level was normalized. This case describes successful management of severe subaortic stenosis in a small breed dog through balloon valvuloplasty.

Aortic Stenosis in Dogs and Cats: Past, Present and Future

“…Balloon valvuloplasty, although with an average 50% reduction in PG after ballooning, has not proved to be a long-term solution, because in most dogs restenosis occured [53]; however, in some cases, it may reduce clinical signs [54].…”
