Key result
Echocardiographic-guided aspiration thrombectomy through an umbilical venous catheter successfully resolved a right atrial thrombus in an extremely premature infant.
Why the study?
Intracardiac thrombi in preterm infants are uncommon but can lead to fatal outcomes.

No
Aspiration thrombectomy can be a successful treatment option for catheter-related right atrial thrombus in preterm infants.
May support aspiration thrombectomy for select neonatal atrial thrombi; hypothesis-generating and requires prospective validation before broader use.
Intracardiac thrombi in preterm infants are not common but may lead to fatal outcomes. Predisposing and risk factors include small vessel size, hemodynamic instability, immaturity of the fibrinolytic system, indwelling central catheters and sepsis. In this paper, we present our own experience with a case of a catheter-related right atrial thrombus in a preterm infant, which was successfully treated with an aspiration thrombectomy. Then, we review the literature on intracardiac thrombosis in preterm infants: epidemiology, pathophysiology, clinical signs, echocardiographic diagnostic features and treatment options are discussed.

Gover et al. (2023) conducted a case report in Intracardiac thrombus (n=1). Aspiration thrombectomy was evaluated on Resolution of right atrial thrombus. Echocardiographic-guided aspiration thrombectomy through an umbilical venous catheter successfully resolved a right atrial thrombus in an extremely premature infant.
