Aims Surgery in patients with infective endocarditis (IE) can be elective (upon completion of antibiotic treatment) or urgent (before antibiotic treatment has ended) when the clinical course is unfavourable. However, urgent surgery for left-sided endocarditis is associated with high mortality. The aims of this study were to describe the profile of patients with left-sided endocarditis who underwent urgent surgery and to analyse the factors that predicted mortality.
Methods and results Among 508 consecutive episodes of IE, 391 were left-sided and 89 required urgent surgery. The main reasons for urgent surgery were heart failure that did not respond to medication (72%) and persistent infection despite appropriate antibiotic treatment (31%). Thirty-two patients (36%) died during their hospital stay. Univariate analysis identified renal failure, septic shock, Gram-negative bacteria, persistent infection, and surgery for persistent infection as factors associated with mortality. Multivariate analysis confirmed only persistent infection and renal insufficiency as factors independently associated with a poor prognosis.
Conclusion Patients with IE who need urgent surgery have a poor clinical course. Heart failure, the main cause of urgent surgery, was not associated with higher mortality. However, persistent infection and renal failure were factors associated with higher post-surgical mortality.
