Late diagnosis of pericardial constriction associated with defibrillator patches and deformation of the left ventricle.

Abstract

We report a case of pericardial constriction associated with defibrillator patches developing 4.5 years after implantation. This constriction was related to the presence of a large pericardial mass that had developed above the defibrillator patch. This mass, which had a calcified superior border, suggested former hematoma associated with pericardial fibrosis. It induced significant compression of the right ventricle and a dumb-bell deformity of the left ventricle. The hemodynamic picture was of elastic-form constrictive pericarditis. Because of previous cerebral stroke during cardiac surgery, the patient was discharged on pharmacologic treatment after improvement of his functional status. Since removal of epicardial patches is an effective treatment of constriction, constrictive pericarditis should be systematically considered in patients with epicardial patch electrodes and impairment of functional status.
