Inclusion Criteria
  1. complex congenital muscular ventricular septal defects (VSD) of significant size to warrant closure. Subjects must meet at least one of the following:

    1. Large volume left to right shunt (Qp/Qs >2:1),
    2. Pulmonary hypertension (PA pressure >50% systemic) and/or
    3. Clinical symptoms of congestive heart failure
    4. Banding of the pulmonary artery(ies) and in the opinion of the treating investigator closure of the VSD is clinically warranted.
  2. Subjects must meet at least one of the following criteria to be considered high risk for standard transatrial or transarterial surgical closure based on anatomical conditions:

    1. Left ventriculotomy or an extensive right ventriculotomy,
    2. Failed previous VSD closure,
    3. Multiple apical and/or anterior muscular VSDs ("Swiss Cheese Septum"), and/or
    4. Posterior apical VSDs covered by trabeculae.
    5. Overall medical condition
  3. Subject/legally authorized representative has signed the informed consent

  4. Subject/legally authorized representative is willing to complete the follow-up requirements of this study

Exclusion Criteria
  1. Subjects with defects less than 4 mm distance from the semilunar (aortic and pulmonary) or atrioventricular valves (mitral and tricuspid)
  2. Subjects with severely increased pulmonary vascular resistance above 7 Wood units and a right-to-left shunt and documented irreversible pulmonary vascular disease
  3. Subjects with perimembranous (close to the aortic valve) VSD
  4. Subjects with post-infarction VSD
  5. Subjects who weigh < 5.2 kg
  6. Subjects with sepsis (local/generalized)
  7. Subjects with active bacterial infections
  8. Subjects with contraindications to anti-platelets

Primary Outcome Measures
NameTimeMethod
Primary Effectiveness End Point: Technical SuccessDuring the procedure

Technical success was defined as successful deployment of the device (Amplatzer™ Muscular VSD Occluder) in subjects with the ventricular septal defect (VSD).

Primary Effectiveness End Point: Acute Procedure SuccessAt the end of the procedure

Acute procedural success was defined as a defect with a ≤ 2mm residual shunt at the conclusion of the procedure, as reported by clinical sites.

Primary Effectiveness End Point: Shunt Closure Success1-year follow-up visit

Subjects in whom a defect has ≤ 2 mm residual shunt at the 1-year follow-up visit (as evaluated by the independent echocardiography board).

Primary Safety EndpointWithin 12 months of the procedure

The proportion of subjects who experienced a serious adverse event (SAE) within 12 months of the procedure.
