title: Ross-Konno procedure for the surgical treatment of prosthesis-patient mismatch after prosthetic aortic valve replacement.
abstract: The Ross-Konno procedure has become a widely recognized surgical method for the treatment of complex left ventricular outflow tract obstruction (LVOTO) in patients of younger age. We applied this method in two young females who presented following mechanical aortic valve replacement with severe prosthesis-patient mismatch (PPM) resulting in significant gradient across the left ventricular outflow tract and congestive heart failure. In both cases the postoperative course was uneventful with immediate improvement in clinical symptoms. Both patients remain in excellent clinical and hemodynamic condition four and six years after the Ross-Konno procedure.
