Canadian Adult Congenital Heart Disease Intervention Registry

An observational study in Atrial Septal Defect, Patent Foramen Ovale and Tetralogy of Fallot, sponsored by University Health Network, Toronto. Not yet recruiting at 1 site in Canada. Open to participants aged 18 Years to 110 Years. Per ClinicalTrials.gov, last updated 2020-02-28.

  1. The study's listed conditions name Foramen Ovale, Patent, a narrower term within Heart Septal Defects, Atrial.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The ACHDi Registry study will create a foundational database for adult congenital heart disease interventions. This Pan-Canadian Registry will collect clinical and patient-reported information that will enable the evaluation of care processes and outcomes in five most common ACHDi interventions by enabling prospective and retrospective registry-based studies to answer important clinical practice and policy-relevant questions.

Read the detailed description

The goal of this study is to establish a rigorously developed registry to enable an impactful research agenda in adults with congenital heart disease interventions (ACHDi). The clinical and patient-reported information captured in the Registry will allow researchers to evaluate care processes and outcomes in five most common ACHDi interventions including transcatheter closure of atrial septal defects, closure of patent foramen ovale, coarctation of aorta stenting, percutaneous pulmonary valve implantation, and complex catheterization.

In 2019, we established the Canadian Research Network for ACHD Interventions (CRN-ACHDi), a national ACHD research network bringing together researchers, providers, patients, and policymakers from 4 provinces (Alberta, British Columbia, Ontario and Quebec) to improve patient experiences and outcomes through i) a national registry with modern data platform; ii) a rigorously established national research priorities agenda; and iii) a strong collaborative and multidisciplinary research environment.

The C-ACHDi Registry will provide opportunities for researchers to ask clinical practice and policy-relevant research questions that are supported by high quality data. In addition, it will provide an opportunity for patients to contribute data for meaningful and high quality clinical and translational research. The C-ACHDi Registry will provide a base for conducting registry-based studies (e.g., prospective experimental, prospective and retrospective observational) in the future as well as a foundation for benchmark and quality improvement activities.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 28, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
