Key result
Intraoperative TEE guides successful surgical retrieval of embolized ASO devices in two cases.
Why the study?
Embolisation of atrial septal occluder devices into the pulmonary artery is a known complication requiring surgical retrieval, but detailed pathophysiology and intraoperative imaging roles are not well described.
Case Report (n=2)
Surgical retrieval guided by intraoperative transoesophageal echocardiography is an effective management strategy for ASO devices that embolise into the pulmonary artery.
Atrial septal defect is usually closed in the cardiac catheterisation laboratory using atrial septal occluder (ASO) device. One of the complications associated with the procedure is embolisation of the device into the pulmonary artery. We are reporting two cases wherein the pulmonary embolisation of ASO device occurred during the procedure in one patient and in the early post-procedure period in another; both were retrieved surgically. We are also describing the haemodynamic consequences of this complication and the role of intraoperative transoesophageal echocardiography during surgical retrieval of the device.

Gadhinglajkar et al. (2009) conducted a case report in Atrial septal defect with embolised atrial septal occluder device (n=2). Surgical retrieval and intraoperative transoesophageal echocardiography was evaluated. Surgical retrieval guided by intraoperative transoesophageal echocardiography was used to manage two cases of pulmonary embolisation of an atrial septal occluder device.
