Intracardiac fungal masses in high-risk neonates: clinical observations

Four cases of intracardiac fungal masses occurred over 2 y amongst 7 cases of systemic candidiasis in a neonatal referral unit. The gestations and birthweights were 25, 23, 24 and 30 wk and 805, 605, 640 and 1395 g, respectively. The pedunculated, solitary right atrial masses were detected 2-17 d after diagnosing candidemia in 3 cases, whereas it was the presenting feature in the 4th. All had indwelling right atrial catheters and received multiple courses of broad-spectrum antibiotics. The masses were removed successfully in two cases fit for surgery. None survived despite antifungal therapy, including liposomal amphotericin B at 6 mg/kg/d. Early introduction of enteral feeds, minimization of prolonged exposure to broad-spectrum antibiotics and judicious use of central catheters may reduce the incidence of systemic candidiasis in high-risk neonates. Surveillance echocardiography and timely surgical intervention may reduce the mortality and/or morbidity related to intracardiac fungal masses.
