Details and patient eligibility

About

To ascertain the potential symptom improvement assessed by Cardiopulmonary Exercise Testing (CPET) in subjects with heart failure with preserved ejection fraction (HFpEF) and nonthrombotic iliofemoral venous lesions and/or iliocaval obstruction defined by MR or CT venography AND CEAP Clinical Category ≥3 prior to venous stenting.

Full description

Primary Objective:

Evaluate potential improvement in metrics of functional capacity assessed by Cardiopulmonary Exercise Testing performed before and after venous stenting of an ≥50% iliofemoral venous obstruction by MR or CT venography and confirmed by intra-procedural IVUS in a prospective patient cohort presenting with heart failure with preserved ejection fraction with a H2FpEF score of ≥4 AND a CEAP Category ≥3.

Secondary Objectives:

Identify patient demographic, baseline laboratory, imaging, procedural and Cardiopulmonary Exercise Testing variables and the FDA-approved Minnesota Living with Heart Failure Questionnaire as a Medical Device Development Tool (MDDT) in patients with and without functional improvement as assessed by Cardiopulmonary Exercise Testing VO2max after successful venous stenting of iliofemoral/iliocaval venous obstructions.

Enrollment: 3 patients

• Subject has an allergy to contrast media that cannot be adequately pre-treated prior to the required diagnostic and/or endovascular procedures.
• Subject has an active peptic ulcer or active gastrointestinal (GI) bleeding.

• Subject is currently participating in another investigational drug or device study.
• Subject intends to participate in another investigational drug or device study within 30 days after the index procedure.
• Subject has moderate or severe pulmonary disease (i.e., COPD) considered by Investigator to be a major contributing factor to the subject's exertional dyspnea
