During procedures that use a transeptal approach, which chamber is accessed directly?

Explanation:
A transeptal approach directly targets the left atrium. It involves puncturing the interatrial septum, usually at the fossa ovalis, from the right atrium to create a direct path into the left atrium for catheter access. This is what makes the left atrium the chamber being accessed. The right atrium is where the procedure typically starts, but the goal of this technique is to reach the left atrium in one step. The right ventricle and pulmonary artery are not accessed directly by this method.
