Surgical treatment of active infective endocarditis: A single center experience
Abstract
Objective: This study was undertaken to examine the outcomes of surgery for active infective endocarditis.
Methods: Fifty consecutive patients underwent surgery for active infective endocarditis in a tertiary care center between January 2000 and June 2003. Modified Duke Criteria was used to include the patients in the study.
Results: Mean age of the patients was 55.72 years (range 18-89 years). Underlying heart disease was the most common cause of acute infection, accounting for 30 % of all the cases. 16 % patients had a recent dental procedure and 10 % had a recent surgical procedure. The most common infective organism was staphylococcus aureus (24%), followed by streptococcus viridians (20%). The most common indications for surgery were congestive heart failure (CHF) (52%), embolic phenomenon (18%) and septic shock (10%). Most common postoperative complication was respiratory failure (30%) followed by renal failure (24%) pacemaker implantation 22%; stroke 18%, bleeding 16% and GI bleeding 2 %. Seven out of 50 patients died during hospital course that accounts for 14% of the motility rate.
Conclusion: Surgery for endocarditis continues to be challenging and associated with high operative mortality and morbidity. Age, shock, prosthetic valve endocarditis, impaired ventricular function, and recurrent infections adversely affect long-term survival.
