Epicardial pacemaker complicated by cardiac tamponade and constrictive pericarditis.
Following insertion of an epicardial pacemaker, our patient developed cardiac tamponade complicated by subacute constrictive pericarditis. Echocardiographic findings and intracardiac pressures were typical of constrictive pericarditis, which was confirmed at surgery. Although rare, these unusual complications should be considered in patients who develop evidence of reduced cardiac output following either transvenous or epicardial electrode placement.
