Abstract:
Patient with subaortic stenosis due to the insertion of anomalous chordae tendineae of the mitral valve in the interventricular septum (mitral web) associated with mitral stenosis with diagnosis made by bidimensional echocardiographic study with Doppler and confirmed by hemodynamic study. The patient was submitted to surgical treatment. The anomalous cords were resected and the mitral valve with severe malformation was replaced by a bioprosthesis. The patient had a uneventful recovery and echocardiographic evaluation showed an outflow tract without obstruction, with no gradient, with remnants of the papillary muscles and normo-functioning bioprosthesis.
