Detailed Description
PARADIGM is a prospective, international, multi-center, single arm study to demonstrate the safety and effectiveness of the AVP III for percutaneous, transcatheter closure of PVLs occurring after aortic or mitral valve replacement with a surgically-implanted mechanical or bioprosthetic valve.
The study will be conducted at up to 25 clinical sites in the US, EU and Canada, where a total of 200 subjects with a clinically significant PVL will undergo an AVP III implant procedure for PVL closure.
Pre-procedural Baseline and follow-up assessments at Discharge, 30 days, 6 months and 1 year will include echocardiography, physical examinations, lab measurements and questionnaires to assess PVL severity, prosthetic valve function, hemolytic anemia, heart failure symptoms, and quality of life.
Adverse events will be recorded throughout the study.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Subject is implanted with a mechanical or biological surgical valve in the aortic or mitral position
- Note: Subjects in European countries can only be implanted with a mechanical valve in the aortic or mitral position
- Subject has a clinically significant paravalvular leak with a severity grade of moderate or higher, associated with signs of heart failure and/or hemolysis necessitating recurring blood transfusions.
- Subject has one clinically significant PVL defect that can be closed with a single AVP III as assessed pre-procedurally
- Subject has provided written informed consent
- Subject is ≥18 years old
Exclusion Criteria:
- Subject has a rocking valve or extreme dehiscence of the prosthetic valve involving more than 40% of the sewing ring
- Subject's PVL(s) originates from a transcatheter aortic or mitral valve replacement, or from rapid deployment or sutureless surgical replacement valves
- Subject has a prosthetic aortic valve and prosthetic mitral valve which both have a clinically significant paravalvular leak.
- Subject who is hemodynamically unstable or who cannot undergo an elective procedure
- Subject with active endocarditis or other active infection
- Subject has within the last 6 months a previously documented intracardiac mass, vegetation, tumor, or thrombus which would interfere with placement of the AVP III
- Subject has inadequate vasculature for delivery of the AVP III
- Subject has unsuitable anatomy for PVL closure using the AVP III (such as a PVL associated with an abscess cavity or a pseudoaneurysmal sac) or anatomy where the AVP III would interfere with other intracardiac or intravascular structures (such coronary ostia)
- Subjects who are unable to receive intraprocedural anticoagulant therapy
- Pregnant or nursing subjects or subjects who plan pregnancy during the clinical investigation follow-up period.
- Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results.
- Life expectancy is less than 1 year in the opinion of the Investigator
- Incapacitated individuals, defined as persons with mental illnesses or handicaps that impair their ability to provide informed consent, or individuals without legal authority to provide informed consent.
- Individual who are currently participating in an investigational drug or device study that has not reached the primary endpoint or that may confound the results of this study
