An atrial shunt is a septal shunt left heart decompression device that diverts pressure from the left atrium to the right atrium in heart failure patients, thus solving the problem of unilateral heart function in patients. Atrial shunt is an emerging technical direction in international heart failure device therapy in recent years, through ultrasound-guided femoral vein, by the guidewire to establish the track, the interventional minimally invasive way in the septum implantation of a shunt device, reduce the left heart displacement to increase the load of the right heart to alleviate the symptoms of heart failure. Compared with the traditional device treatment, it has the characteristics of wide indications, economic safety, easy to promote, etc. These products are also cheaper than the traditional heart failure devices. Atrial shunts are currently the only shunt devices that can be retrieved, i.e., they can still be retrieved through percutaneous intervention in a minimally invasive manner at any point in the postoperative period once adverse hemodynamic changes have been observed in the patient (assuming that the patient has occult right heart dysfunction that was not observed preoperatively). If required, it is recommended that this should be done under the formal guidance of a physician, choosing the appropriate treatment according to the needs of the patient’s condition.
