Streptococcus Agalactiae endocarditis is a rare clinical entity in newborns with a normal structured heart. It is generally characterized by acute onset, the presence of large vegetations, rapid valvular destruction and frequent complications, particularly embolization. Mortality is high with medical therapy alone. We are reporting a rare case of infective endocarditis (IE) with mitral valve vegetation in a 9 days old healthy newborn following Streptococcus Agalactiae sepsis, complicated by meningitis and micro-abscesses. Mitral valve (MV) vegetation was removed surgically; the patient received intravenous antibiotics for six weeks. Transthoracic echocardiography after surgery showed severe MV regurgitation and severe pulmonary hypertension which was successfully managed by conservative care with cardiac medications.
