Background: Infective endocarditis (IE) is an uncommon but a potentially life-threatening infectious disease in children. The epidemiology of IE has changed in the past three to four decades and its incidence has been increasing recently. This case with atypical present including culture-negative and no-cardiovascular diseases got cardiovascular structural damage that deteriorate in short time.
Case presentation: This case was an infant less than one year old without basic cardiovascular disease,and this case was admitted with Kawasaki disease early. His diagnosis was infective endocarditic aortic valve abscess with perforation. The patient received intravenous injection of cefotaxime for two days and piperacillin sulbactam and cefazolin for six days. On 9 th day, piperacillin sulbactam combining with vancomycin were used. On 10 th day, the patient was sent to cardiac surgery department to receive aortic valve repair. The operation is successful.The abscess cavity of the inferior aortic valve and the vegetations on the aortic valve were completely removed, the left coronary valve was removed, and the left coronary valve was locally widened by autologous pericardial patch.
Conclusions: Infective Endocarditis in children may be difficult to diagnosis and manage.and the treatment are becoming a new challenge for conventional antibiotic therapy. Some IE require serial follow-up to determine potential need for subsequent cardiovascular surgery (CVS) intervention despite microbiologic cure with antimicrobial therapy.
