Penumbra Indigo® system to safely remove intracardiac thrombus in a 7-month-old infant with severe immunodeficiency disorder

We report on a 7-month-old boy (4.2 kg/60 cm) with severe immunodeficiency disorder and bacterial septicaemia who was referred for an infected atrial thrombus secondary to a jugular central line. The echocardiogram showed a teardrop-shaped thrombus with a wide base adherent to the interatrial wall and a flimsy tail moving freely in the right atrium. Chest CT scan showed multiple lesions in both lungs consistent with infected micro-thrombi. The thrombus increased in size despite 2 weeks of antibiotics and anticoagulation. We applied the Indigo® Lightning® 7 aspiration system from Penumbra® (Alameda, USA) and removed percutaneously the thrombus under transoesophageal ultrasound and biplane fluoroscopic guidance. At 6 weeks of follow-up, the patient is alive, under enoxaparin with no procedure-related complication.
