Percutaneous transcatheter closure of congenital interatrial communication (ie, Fontan fenestration, atrial septal defect) with implant

The procedure described by CPT® Code 93580 involves a percutaneous transcatheter closure of congenital interatrial communication, which refers to an abnormal connection between the left and right atria of the heart. This condition can manifest as an atrial septal defect (ASD), a common congenital heart defect where there is a hole in the wall (septum) that separates the two atria. Additionally, this procedure can be utilized for the closure of Fontan fenestrations, which are intentional openings created during previous surgical procedures to improve blood flow in patients with complex congenital heart defects. The closure of these defects is critical as they can lead to complications such as heart failure, arrhythmias, and increased risk of stroke. The procedure is performed using an implant, which is a device designed to occlude the defect effectively. The approach is minimally invasive, typically involving access through the femoral artery, allowing for a quicker recovery and reduced risk compared to traditional open-heart surgery. The use of imaging techniques, such as echocardiography and angiography, ensures accurate placement of the implant and assessment of the defect before and after closure.
