Cardiac implanted electronic device-related infective endocarditis: clinical features, management, and outcomes of 80 consecutive patients.

Background: The use of cardiac implantable electronic devices (CIEDs) has expanded dramatically over the past decade, but net clinical benefit has been curtailed by increasing infectious complications. In particular, CIED-related infectious endocarditis (IE) is a serious condition with significant morbidity and mortality.

Methods: We performed a single-center, retrospective study between July 2006 and February 2011 with CIED-related IE, defined by either lead vegetations detected on echocardiography or by fulfilling Duke criteria for definite endocarditis.
