What is the difference between using CPT code 33340 and 93580?

"I advanced a JR4 catheter over a J-wire into the lower portion of the inferior systemic venous baffle and advanced a pigtail catheter retrograde into the body of the left ventricle and left the guidewire in it to act as an additional landmark to guide the direction of the transbaffle. I proceeded with closure of the atrial septal defect to eliminate the possibility of a paradoxical embolus given his transvenous pacer leads and atrial shunt. The Agilis sheath was still across the defect, and based on the size, I chose a 5 mm Amplatzer Septal Occluder. This was carefully prepared and de-aired and advanced through the Agilis sheath. The wire and dilator were removed and the sheath carefully flushed. I advanced the septal occluder through the delivery sheath and using intracardiac echo and fluoroscopic guidance, deployed the distal disk in the pulmonary venous side of the baffle, pulled everything back until there was good tension and then deployed the remainder of the device on the systemic venous side."
