Abstract

Interatrial shunts are described herein that are designed to benefit both the left side of the heart and the right side of the heart. The interatrial shunt is anchored in the atrial septum to permit blood to flow between atrial heart chambers across the atrial septum. In accordance with some aspects, the lumen of the shunt has an effective orifice area selected to permit blood flow across the atrial septum to unload the patient's left ventricle with beneficial effects on the patient's right ventricle. The shunts are structured to be suitably anchored at the atrial septum for long-term implantation. Further, the shunts preferably have insignificant late lumen loss. The interatrial shunts are expected to treat pathologies such as heart failure and pulmonary hypertension.
