简要总结
Patients with heart failure and reduced left ventricular ejection fraction (HFrEF, EF ≤ 40%) with mild to moderate functional limitation will be evaluated for treatment via creation of a no-implant interatrial shunt using clinical, echocardiographic, and invasive hemodynamic data.

入选标准
- •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.
- •Medical history within the past 12 months of at least one hospitalization with heart failure as the primary or secondary diagnosis OR treatment with IV diuretics for heart failure.
- •Calculated LVEF (by Echo) ≤ 40% as measured by the study-specific transthoracic echocardiography.
- •Elevated left atrial pressure WITH a gradient compared to right atrial pressure (RAP) documented by: (1) end-expiratory PCWP at peak supine cycle ergometer exercise ≥ 25mmHg AND (2) PCWP greater than RAP by ≥ 5 mmHg, OR (1) ≥ 10 mmHg increase of end-expiratory PCWP at peak supine cycle ergometer exercise compared to resting PCWP AND (2) PCWP greater than RAP by ≥ 5 mmHg. Patients must also have PCWP greater than RAP by ≥ 5 mmHg at rest.
