Obstruçäo da via de saída do ventrículo esquerdo após plastia valvar mitral com implante do anel de Gregori / Obstruction of the left ventricular outflow tract after mitral valvuloplasty with implantation of Gregori's ring

ABSTRACT

Mitral valvuloplasty is efficient for repairing mitral valve disease with few complications. In some cases, obstruction of the left ventricular outflow tract may occur due to systolic anterior motion of the mitral valve. We report the case of a patient with this complication and a pressure gradient between the left ventricle and the aorta of 130 mm Hg after mitral valvuloplasty with implantation of a Gregori's ring. The management was clinical with suspension of the vasoactive drugs and introduction of a beta-blocker. Two years after the surgery, the patient is asymptomatic and has a normal life
