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.
