Infective endocarditis in intravenous drug abusers: patterns of presentation and long-term outcomes of surgical treatment.

Abstract

A new pattern of IE in IVDA is emerging, characterized by more frequent left heart involvement (61.5%), a severe clinical course, and a need for surgery in the active phase. Staph. epidermidis and streptococci are emerging pathogens. Drug abuse does not affect postoperative prognosis when an aggressive surgical attitude is combined with prolonged medical therapy. Higher rates of early recurrence are expected during the follow up period.
