We report a case of infective endocarditis caused by A. defectiva involving the mitral valve in a 12-year-old girl. She received antibiotic treatment for 8 weeks and was symptom-free 6 months after discharge. We also reviewed the pediatric cases of nutritionally variant streptococcal endocarditis published in the English literature since 1971.[SDGs]SDG2[SDGs]SDG3aminoglycoside antibiotic agent; amoxicillin; ampicillin; antibiotic agent; beta lactam antibiotic; cefotaxime; ceftriaxone; clindamycin; dalfopristin plus quinupristin; digitalis; diuretic agent; gentamicin; levofloxacin; meropenem; oxacillin; oxytetracycline; penicillin derivative; rifampicin; streptomycin; teicoplanin; vancomycin; antiinfective agent; Abiotrophia defectiva; antibiotic therapy; article; bacterial endocarditis; case report; childhood disease; drug fever; female; human; medical literature; mitral valve disease; mouth flora; priority journal; publication; school child; Streptococcus; bacterial endocarditis; child; classification; drug combination; follow up; microbiology; mitral valve; review; Streptococcus; Streptococcus infection; Taiwan; treatment outcome; valvular heart disease; Antibiotics, Combined; Case Report; Child; Endocarditis, Bacterial; Female; Follow-Up Studies; Heart Valve Diseases; Human; Mitral Valve; Streptococcal Infections; Streptococcus; Taiwan; Treatment Outcome; Anti-Bacterial Agents; Child; Drug Therapy, Combination; Female; Follow-Up Studies; Humans; Mitral Valve; Taiwan; Treatment Outcomejournal article10.1097/00006454-200207000-00018122376062-s2.0-0036020212
