Atrial septal defect device closure

This procedure is called as Atrial septal defect (ASD) device closure.


Transesophageal echocardiography (TEE) is must before procedure for:
1) actual sizing of the defect
2) defining the rims - to hold device in place
3) ruling out anomalous pulmonary venous drainage
4) ruling out significant mitral regurgitation (MR).
Intraprocedural TEE is not mandatory.


N.B How to distinguish between an ASD device and a patent foramen ovale (PFO) device? Left atrial (LA) disk (green arrow) is larger than Right atrial (RA) disk (yellow arrow), thus it is an ASD device.For a PFO device, RA disk will be larger than LA disk.
