Clinical Trials

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

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
