title: [Current status of endocarditis prevention].
abstract: There are currently no randomized and carefully controlled human trials to definitively prove that endocarditis prophylaxis is efficient. Furthermore, most cases of endocarditis are not attributable to a medical procedure. Thus, even with a high level of application of endocarditis prophylaxis only a minority of cases could be prevented. Endocarditis is a rare disease. On the other hand, its morbidity is increasing! In addition, infective endocarditis remains still a major medical concern because of its mortality between 5% and 76%. In addition, in up to 40% of all patients suffering from endocarditis one or more heart valves have to be replaced in the following 5 to 8 years. Without treatment endocarditis has a lethality of 100%. Therefore, there is worldwide agreement that endocarditis prophylaxis is necessary. Combining the recommendations of the German and the American Heart Association, as well as the results of the European consensus conferences, with newer insights into the pathophysiology of endocarditis the following aspects are elucidated: depending on their risk of endocarditis patients are allocated into 3 groups. In the first group there are patients with prosthetic cardiac valves, patients who suffered from previous endocarditis and patients with complex cyanotic congenital heart disease and surgically constructed shunts or conduits of the aorta and/or pulmonary circulation. In these high-risk patients the prophylactic regimen for dental, oral, respiratory tract procedures is oral amoxycillin. In genitourinary and gastrointestinal procedures ampicillin and gentamicin i.v. is recommended. In patients with mostly congenital cardiac malformations, acquired valvular dysfunction, hypertrophic obstructive cardiomyopathy and mitral valve prolapse or thickened leaflets and valvular regurgitation oral amoxycillin is recommended for all medical procedures (second group). The third group consists of patients with isolated secundum atrial defect, previous coronary bypass graft surgery, patients with cardiac pacemakers or defibrillators. In this patient cohort the individual risk of endocarditis is not higher than in the general population. Therefore, endocardits prophylaxis is not recommended.
