1Service de Cardiologie, CHU Liège, Belgique.
Insights
Atrial septal defect (ASD) and patent foramen ovale (PFO) are common heart conditions. Percutaneous closure is a recommended therapy for ASD and increasingly for PFO to prevent stroke.
Area of Science:
- Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Atrial septal defect (ASD) is a common congenital heart disease leading to right heart volume overload and increased morbidity/mortality.
- Patent foramen ovale (PFO) persists in ~25% of adults, potentially causing paradoxical embolism and cryptogenic stroke.
Purpose of the Study:
- To discuss the indications and procedures for percutaneous closure of ASD secundum-type.
- To review the emerging role of percutaneous PFO closure for cryptogenic stroke prevention.
Main Methods:
- Percutaneous closure of secundum-type ASD as a first-line therapy.
- Percutaneous closure of PFO in patients with cryptogenic stroke.
Main Results:
- Percutaneous ASD closure is a recommended first-line therapy.
- Percutaneous PFO closure shows a modest but significant decrease in stroke recurrence risk.
Conclusions:
- Percutaneous closure is an effective treatment for ASD secundum-type.
- Percutaneous PFO closure is a beneficial option for select patients experiencing cryptogenic stroke.
Abstract:
Atria septal defect (ASD) is one of the most common congenital heart disease. ASD can be responsible for a volume overload of the right chambers associated with an increased morbi-mortality. In these circumstances, percutaneous closure of ASD secundum-type is recommended as a first line therapy. The persistence of a patent foramen ovale (PFO) is found in approximately 25 % of adults. This anomaly can be responsible for paradoxical embolism, especially cryptogenic stroke. Recent studies have shown a clinical benefit to the percutaneous closure of FOP in cryptogenic stroke, with a modest, but significant, decrease in the risk of recurrence. In this article, we discuss the indications and procedure for percutaneous closure of ASD and PFO.
