Pulmonary arterial hypertension (PAH) is a severe, progressive and fatal disease. The creation of an interatrial right-to-left shunt in patients with PAH may enhance systemic ventricular output at the expense of desaturation. However, creating sustainable restricted interatrial communication is challenging. We describe the successful use of an atrial flow regulator, a novel implantable atrial communication device, in a 54-year-old female with severe irreversible PAH.
