  • Title: [Surgery for bacterial endocarditis. When?].
    Author: Acar J, Michel PL.
    Journal: Arch Mal Coeur Vaiss; 1993 Dec; 86(12 Suppl):1863-7. PubMed ID: 8024392.
    Abstract:
    In 1993, infectious endocarditis (IE) remains a common and serious condition. Surgery has become an essential feature of treatment in many cases. The choice and optimal timing depend on many factors: the tolerance of the underlying cardiac disease is an important feature, surgery being indicated not only in cases of necessity (refractory cardiac failure) but also as treatment of choice in cases of episodic decompensation even if temporary when related to valvular dysfunction. In these conditions, if the lesion is severe aortic incompetence, surgery can be programmed in two or three weeks after initiating antibiotic therapy; the bacteriological indications are less common: fungal endocarditis, prosthetic valve endocarditis due to gram-negative bacilli or staphylococcus aureus endocarditis, or IE on native valves with persistent signs of sepsis after one week of antibiotic therapy; the occurrence of some complications may require urgent surgery: high degree atrioventricular block, septal perforation, ring or perivalvular abscess detected at echocardiography, single or multiple systemic embolism with persistence of large, mobile vegetations at echocardiography. Conversely, tricuspid valve endocarditis usually respond well to medical treatment alone: surgery (valvuloplasty with excision of vegetations, valvulectomy or, preferably, bioprosthetic valve replacement) is sometimes indicated in septic states related to certain pathogenic organisms. The operative indications in 1993 have become more extensive and earlier: analysis of surgical results shows that operative mortality depends mainly on the haemodynamic status at the time of operation, but also on the severity of the anatomical lesions, the nature of surgery, the type of endocarditis, native or prosthetic valve, and the causal organism.(ABSTRACT TRUNCATED AT 250 WORDS)
