January 14, 2026 updated by: Occlutech International AB

A Multicenter, International, Follow-up Study to Monitor the Efficacy and Safety of the Occlutech® Perimembranous Ventricular Septal Defect (PmVSD) Occluder in Patients With Perimembranous Ventricular Septal Defects

The objective of this registry is to gain more insight on the clinical use of the Occlutech perimembranous VSD occluder.

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

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

There will be no pre-selection of patients for enrollment in this registry. The criteria provided in the Instructions For Use should be followed. The study cohort will thus consist of consecutively enrolled patients at the discretion of the treating physician

Description

Inclusion Criteria:

Patients with haemodynamically significant perimembranous defects which are located in the ventricular septum

Exclusion Criteria:

Occlutech® PmVSD Occluder is contraindicated for the following:

  • Patients with defects less than 2 mm aortic rim and/or interference with the aortic or atrioventricular valves
  • Patients less than 10.0 kg
  • Patients with sepsis (local or generalized)
  • Patients with left ventricle to right atrial shunting
  • Patients with right to left shunting through the defect
  • Patients with PmVSD with an aneurysm and multiple shunts that could not be successfully closed with one device
  • Patients with complex heart lesions such as tetralogy of fallot
  • History of repeated pulmonary infection
  • Any type of serious infection 1 month prior to procedure
  • Malignancy where life expectancy is less than 3 years
  • Demonstrated intracardiac thrombi on echocardiography
  • Patients with allergy to anti-platelet or anticoagulant therapy
  • Patients with allergy to nickel and/or titanium and/or nickel/titanium based materials
  • Patients with intolerance to contrast agents
  • Patients with active bacterial infections
  • Patients with very small vessels which are not suitable for recommended delivery sheath sizes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To confirm the efficacy of Occlutech PmVSD in patients requiring transcatheter occlusion (closure) of perimembranous ventricular septal defects.
Time Frame: 1 year following implantation
The primary efficacy endpoint is defined as successful implantation of the device with a proper closure of the pmVSD (defined as reduction in VSD shunt of more than one grade as assessed by TTE post implantation).
1 year following implantation
To confirm the safety of Occlutech PmVSD in patients requiring transcatheter occlusion (closure) of perimembranous ventricular septal defects.
Time Frame: 1 year following implantation
The primary safety endpoint is defined as absence of Serious Adverse Device Effects (SADEs) including procedure-related death, procedure-related stroke, systemic embolism, severe hemolysis, complete heart block requiring pacemaker implantation or device explantation, new-onset of severe tricuspid regurgitation (TR), new onset of severe aortic regurgitation (AR), device embolization, severe right-left ventricular outflow obstruction (RVOTO-LVOTO), cardiac tamponade, infective endocarditis or vascular complications requiring surgery.
1 year following implantation

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 7, 2019

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
June 1, 2026

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
