PERSUADE: HFpEF and Symptomatic Obstructive Iliofemoral Venous Disease Study
Study Details
Study Description
Brief Summary
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.

Detailed 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.

Outcome Measures
Primary Outcome Measures
- Evaluate potential change in metrics of functional capacity assessed by Cardiopulmonary Exercise Testing performed before and after venous stenting [180 days]
The primary focus of the study is to estimate the change in functional capacity in patients of heart failure with preserved ejection fraction (HFpEF) of varying severities and chronic peripheral venous disease associated with pelvic venous obstruction after resolution via IVUS-guided venous stenting. Key estimate will be the change in functional capacity (i.e., VO2max or 6MWD) as assessed by the percentage change in pre- and post-venous stenting. No formal hypothesis tests are pre-specified.
Secondary Outcome Measures
- Identify patient functional change utilizing the FDA-approved Minnesota Living with Heart Failure Questionnaire as a Medical Device Development Tool (MDDT) post treatment versus pre treatment [180 days]
The secondary outcome measure of the study is to estimate the change in functional capacity in patients of heart failure with preserved ejection fraction (HFpEF) of varying severities and chronic peripheral venous disease associated with pelvic venous obstruction after resolution via IVUS-guided venous stenting. Key estimate will be the change in functional capacity as assessed by the percentage change in pre- and post-venous stenting utilizing the Minnesota Living with Heart Failure Questionnaire (MLHFQ). No formal hypothesis tests are pre-specified.
