Introduction:
Aortoventriculoplasty (known as Konno procedure) was first described by
both Konno and colleagues (1), and Rastan and Koncz (2) for the
treatment of tunnel-type subaortic stenosis. It is considered the final
option for relief of complex left ventricular outflow obstruction
(LVOTO) (3). Originally, it involved patch enlargement of both
ventricles’ outflow tracts along with the insertion of a mechanical
aortic valve prosthesis (1, 2). Later, it became the procedure of choice
for multilevel LVOTO, especially in those with a small aortic annulus
(4, 5). Herein, we present a case of recurrent subvalvar and valvar
aortic stenosis in a 10-year-old boy with associated dextrocardia who
underwent Konno procedure.
