Despite remarkable advances in drug therapy for chronic heart failure (CHF), the related morbidity, mortality and hospitalizations remain substantial. Novel device-based interventions have emerged as potential therapies for CHF. Recently, interatrial shunt device (IASD), baroreflex activation therapy (BAT), and phrenic nerve stimulation (PNS) have shown promise in treating patients with CHF. This article summarizes the working principles and clinical research outcomes of these innovative therapeutic devices, and analyzes their advantages and disadvantages, potential risks, and future application prospects, aiming to provide new insights and references for clinical treatment.
