Occlutech AFR Fontan Study

The Occlutech AFR Fontan Study is a single arm, observational, multicenter clinical investigation of the Occlutech Atrial Flow Regulator investigational device. This is a retrospective, non-interventional, observational study that utilizes existing clinical data previously collected during standard patient care. No new procedures or treatments will be administered as part of this study. This study will comprise a case series of congenital patients with Fontan failure who have been treated with an Occlutech AFR. The scope of this study is to gain clinical experience on the Occlutech AFR in Fontan failure patients. Cases in this study will be assessed to evaluate the safety and effectiveness of the device in a real-life scenario. Sites will be selected in the U.S. that had previously attempted expanded access cases with the Occlutech AFR for Fontan failure. Data will be collected retrospectively up to a site-specific cut-off date, which will be either the date of IRB submission or IRB approval, per site IRB policy. The requirement for informed consent and HIPAA authorization will be determined by each IRB in accordance with applicable policies; waivers may be obtained where permissible. It is anticipated that 7 sites will be initiated for the study, and data from approximately 25 patients will be included. Data will be descriptively compared to those available in the literature describing interventions on Fontan to modulate fenestration size.
