[Complete heart block after percutaneous mitral valvotomy with Inoue balloon]. / Bloqueio atrioventricular completo após valvoplastia mitral percutânea com balão de Inoue.

ABSTRACT

We report a permanent complete heart block, in a 27 year-old female patient, developed during mitral percutaneous valvotomy using a single inflation of the Inoue balloon catheter. After one month, even using corticoids, a Mobitz II second-degree atrioventricular block persisted, the patient became symptomatic to moderate efforts and a cardiac pacemaker was implanted.
