Atrial septectomy or septostomy is a specialized palliative surgical procedure aimed at enhancing oxygen saturation in patients diagnosed with complete transposition of the great arteries, a congenital heart defect. This procedure is critical for improving the patient's overall oxygenation and is performed using two distinct methods: the balloon method and the blade method. The balloon method, known as Rashkind balloon septostomy, involves the use of a balloon catheter to create an opening in the atrial septum, allowing blood to flow between the left and right atria. In contrast, the blade method, referred to as Park septostomy, utilizes a blade-tipped catheter to incise the atrial septum directly, thereby enlarging the interatrial communication. Both methods are initiated through a small incision made in the groin, where the femoral vein is accessed. The procedure includes cardiac catheterization, which is essential for guiding the catheter to the heart's atria. The choice between the two methods depends on the specific clinical scenario and the desired outcome for the patient.
