Egyéb

• 6-minute walk distance less than 50 m or greater than 450 m performed during screening.
• Documented atrial fibrillation with ventricular rate greater than 100 BPM at screening.
• Presence of anatomic anomaly that precludes creation of interatrial shunt (including patent foramen ovale, atrial septal defect, target septal thickness greater than 3 mm)
• SBP greater than 170 mmHg at screening.
• Documented left ventricular end diastolic diameter greater than 6 cm.

• 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..
• LVEF (by Echo) > 40% as measured by the study-specific transthoracic echocardiography.
• Echocardiographic evidence of diastolic dysfunction documented by one or more of the following as measured by the study-specific transthoracic echocardiography protocol:
  • LA diameter > 4cm
  • LA volume index >28 mL
  • Lateral e' <10 cm/s
  • Septal e' <8 cm/s
  • Lateral E/e' >10
  • Septal E/e' >15
• As measured by the study-specific exercise hemodynamic right heart catheterization protocol performed during screening: 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.
