About this trial

This study will demonstrate the safety and effectiveness of the Edwards Lifesciences SAPIEN 3/SAPIEN 3 Ultra RESILIA Transcatheter Heart Valve (THV) Systems in subjects with a dysfunctional right ventricular outflow tract (RVOT) conduit or previously implanted valve in the pulmonic position with a clinical indication for intervention.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Weight ≥ 20 kg (44 lbs.)

Dysfunctional RVOT conduit or previously implanted valve in the pulmonic position with a clinical indication for intervention and with a landing zone diameter ≥ 16.5 mm and ≤ 29 mm immediately prior to study device insertion as per the Instructions for Use

Subject presents with at least moderate PR and/or mean RVOT gradient ≥ 35 mmHg.

The subject/subject's legally authorized representative has been informed of the nature of the study, agrees to its provisions and has provided written informed consent.

Disqualifiers

Active infection requiring current antibiotic therapy (if temporary illness, subject may be a candidate 2 weeks after discontinuation of antibiotics)

History of or active endocarditis (active treatment with antibiotics) within the past 180 days

Leukopenia, anemia, thrombocytopenia or any known blood clotting disorder

Inappropriate anatomy for femoral introduction and delivery of the study valve

Trial outcomes

Primary outcomes

1

THV dysfunction

Defined as a non-hierarchical composite of: RVOT reintervention, Moderate or greater total pulmonary regurgitation (PR) via Transthoracic Echocardiography (TTE), Mean RVOT gradient \> 40 mmHg via TTE
