Introduction |
A diagnosis of ductal infective endocarditis (DIE) usually relies on the clinical histories of infectious syndrome, results of blood cultures and echocardiography. It remains a therapeutic challenge. The prognosis is still poor. Is the prevention of infective endarteritis a valid reason to always close the isolated silent PDA in childhood? The question is not yet eluded [1, 2, 3, 4].
We present the case of six years old girl with DIE developed after dental procedure. The patient was managed by combined medical and early surgery with favorable evolution.
Case report |
A six year old girl was admitted to our service with tachypnea, fatigue and fever lasting for seven days. The patient had dental procedures few days earlier. The physical examination revealed a temperature at 40°C and a left subclavian murmur. The acute phase marker levels were significantly elevated and β-hemolytic group A streptococcus was grown in his blood culture. Echocardiography revealed vegetations with the diameter of 10mm on the left side of the PDA (Fig. 1) with turbulent flow in the left pulmonary artery. Treatment with ceftriaxone 200mg/kg/day and gentamycin 5mg/kg/day was started then readapted according to antibiogram. The operation was performed on day 15 of antibiotherapy (Fig. 2a and b), whom was continued for 4 weeks. The fever did not return and the clinical course of the patient was stable; the final echocardiogram revealed the absence of left ventricular dilatation with a correct systolic function, normal pulmonary pressure. She was discharged four weeks after the surgical cardiac procedure.
Conclusions |
Infective endarteritis (IE) complicating PDA is very rare nowadays and the risk is very low especially in the industrialized world. Indeed, standardized management by a skilled multidisciplinary team with expertise in imaging, surgery and intensive care has proven to decrease mortality [3, 4, 5, 6, 7]. Primary prevention is vital. Even though it was not clear if the closure of a small PDA was beneficial, routine closure of any PDA in children and young adults appeared reasonable. The reasons for this recommendation included the risk of infective endocarditis and low-or-zero morbidity from closure, especially when using a transcatheter device [8, 9].
