Patent Foramen Ovale Closure: British Cardiovascular Intervention Society Position Statement

Area of Science:

• Cardiovascular Science
• Medical Interventions
• Congenital Heart Conditions

Background:

• The foramen ovale is a fetal structure allowing placental blood flow to the systemic circulation.
• In 25% of individuals, the foramen ovale (specifically the primum septal flap) does not fully seal after birth, resulting in a patent foramen ovale (PFO).
• Most PFOs are small, with shunting occurring primarily during Valsalva maneuvers; resting right-to-left shunts are less common (5% of individuals).

Purpose of the Study:

• To provide a position statement on the diagnosis of patent foramen ovale (PFO).
• To outline the indications for PFO closure.
• To describe the procedural aspects of PFO closure.

Main Methods:

• This document represents a position statement from the British Cardiovascular Intervention Society.
• It synthesizes current knowledge and expert opinion on PFO management.
• The statement details diagnostic modalities and interventional techniques for PFO closure.

Main Results:

• The document addresses the prevalence and functional significance of PFO.
• It delineates specific clinical scenarios warranting PFO closure.
• Guidance is provided on the technical aspects and best practices for PFO closure procedures.

Conclusions:

• Patent foramen ovale is a common condition with varying degrees of clinical relevance.
• Timely diagnosis and appropriate patient selection are crucial for successful PFO closure.
• This position statement serves as a guide for clinicians managing patients with PFO.
