The invention discloses a three-dimensional atrial septal puncture method including positioning the heart from a body surface by a three-dimensional projection positioning method and displaying interventional instruments by the three-dimensional system and guiding the same into a heart cavity. The method also includes constructing a right atrium three-dimensional model by delivering a catheter with a positioning device to the right atrium and reconstructing and fusing pre-operative image data by the three-dimensional system. The method also includes setting parameters, connecting an interventional operating device with a pressure sensor tail wire and an electrode tail wire, and displaying a guidewire or a puncture needle. The method includes delivering and positioning the long sheath, analyzing and marking the fossa ovalis position by a structure and potential method. The method also includes analyzing the pressure difference between the left atrium and the right atrium, and judging whether the puncture is successful.
