nderwent aortic valvotomy by cardiopulmonary bypass. At three years of age
the aortic stenosis recurred and the child underwent a balloon aortic valvu
loplasty, but developed severe aortic insufficiency after the procedure. Th

ar and valve pulmonary autograft for substituing the aortic root (Ross-Konn
o technique). As for as we know this Is the first report on the Ross-Konno
procedure in Spanish journals.
