Insights
Transcatheter closure is standard for atrial septal defects (ASDs). This case report details using two GORE Septal Occluders (GSO) to successfully close multiple ASDs, a challenging scenario.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Transcatheter closure is the standard of care for secundum atrial septal defects (ASDs).
- Multiple or fenestrated ASDs present challenges for device closure.
- Limited data exists on using multiple devices for complex ASDs.
Observation:
- This case report details the first clinical use of two GORE Septal Occluders (GSO) in a patient with multiple ASDs.
- The patient had a complex anatomy with multiple and fenestrated atrial septal defects.
- The GSO device offers enhanced conformability and closure performance.
Findings:
- Successful closure of multiple ASDs was achieved using two GSO devices.
- The implantation demonstrated the feasibility of using multiple GSO devices in complex cases.
- The GSO devices provided satisfactory apposition and closure performance.
Implications:
- This approach may offer a viable solution for patients with multiple or fenestrated ASDs.
- Further research is warranted to evaluate the long-term outcomes of using multiple GSO devices.
- This case expands the understanding of transcatheter closure options for complex congenital heart disease.
Abstract:
Transcatheter closure of an atrial septal defect (ASD) is considered the standard of care for most of the patients with secundum ASD. The existence of multiple or fenestrated ASD may constitute a challenge to achieve a satisfactory result. Data on the usage of multiple devices for closing multiple defects are limited. The GORE Septal Occluder (GSO) represents a new generation of transcatheter ASD occluders with a design that provides superior conformability, apposition, and closure performance compared with the previous GORE HELEX device. The present case report describes the first clinical experience with the implantation of two GSO devices in a patient with multiple ASDs and fenestrated septum.
