An Early Feasibility Study Evaluation of an Implant Free Interatrial Shunt to Improve Heart Failure
The purpose of this early feasibility study is to evaluate the safety and feasibility of the device for percutaneous shunting of the interatrial septum and improvement of heart failure related symptoms. The primary goal is to determine if the device is safe to use. The findings from this study may be used to refine the intended patient population, the design of the device, or develop a subsequent randomized study.
• NYHA Class II at screening with a prior history of greater than NYHA Class II, OR NYHA Class III at screening, OR ambulatory Class IV at screening: with documented medical history of heart failure for at least 6 months prior to the screening visit.
• At least one hospitalization for heart failure OR treatment with IV diuretics for heart failure OR elevated BNP in the prior 12 months.
• Receiving maximally tolerated guideline directed medical therapy for Heart Failure management.
• LVEF ≥ 20% and ≤ 40% according to baseline echocardiography.
• Resting right heart catheterization demonstrates elevated PCWP compared to right atrial pressure.
