Minimally Invasive Pericardiotomy as a New Treatment for Heart Failure With Preserved Ejection Fraction - The PeriCut Catheter System Early Feasibility Study (REIMAGINE HFpEF)
The PeriCut early feasibility study will evaluate the safety and feasibility of successfully performing a minimally invasive pericardiotomy in patients with heart failure with preserved ejection fraction using the PeriCut Catheter System.
• Age ≥ 30 years
• Symptoms of severe dyspnea (NYHA Class III-IV) without evidence of a non-cardiac or ischemic explanation for dyspnea
• Ejection fraction of ≥50%, determined on most recent imaging study within the preceding 2 years (730 days), with no change in clinical status, suggesting potential for deterioration in systolic function.
• Documentation history of at least one of the following:
⁃ Any previous hospitalization for HF (\>30 days prior to enrollment) with radiographic evidence of pulmonary congestion (pulmonary venous hypertension, vascular congestion, interstitial edema, pleural effusion) or Elevated NT-proBNP (\>300 pg/ml or \>600 pg/ml if in atrial fibrillation) or Echocardiographic evidence of diastolic dysfunction/elevated filling pressures manifested by medial E/e' ratio ≥15 and/or left atrial enlargement and chronic treatment with a diuretic for signs or symptoms of heart failure or Historical catheterization documented elevated filling pressures at rest (PCWP ≥15 or LVEDP ≥18) or with exercise (PCWP ≥25), prior to consent.
• Catheterization documented elevated filling pressures at rest (PCWP ≥15 or LVEDP ≥18) or with exercise (PCWP ≥25) during the screening/baseline visit (after consent)
• Ambulatory with ability to complete 6-minute walk and cardiopulmonary exercise test (not wheelchair / scooter dependent)
