Acute severe mitral regurgitation as an early complication of pacemaker implantation

Abstract

A 70-year-old man developed drug refractory acute pulmonary oedema secondary to acute severe mitral regurgitation (MR) immediately after implantation of a dual-chamber pacemaker for complete heart block. Clinical improvement occurred after allowing the patient to resume his native rhythm. A new lead was positioned within the right ventricular outflow tract (RVOT). The echocardiogram during pacing at RVOT showed minimal MR. Published on behalf of the European Society of Cardiology. © 2010 The Author.
