An interatrial shunt device includes an opening main body. The opening main body includes an opening component for penetrating the atrial septum and expanding the atrial septal tissue to form an opening. An ablation mechanism that may damage the tissue activity at the opening of the atrial septum is disposed where the opening component contacts the atrial septal tissue. An interatrial shunt system includes the interatrial shunt device, a control mechanism of the interatrial shunt device, and an ablation power source.
