Premature closure of foramen ovale

Last edited: 4/15/2026

Overview

Premature closure of the foramen ovale (PFO) refers to the incomplete closure of the fetal opening between the atria, which typically closes shortly after birth but may persist in some individuals, potentially leading to paradoxical embolism and other cardiovascular issues 1.

Diagnosis

  • Echocardiography is the primary diagnostic tool for identifying PFO 1.
  • Transesophageal echocardiography (TEE) offers higher resolution compared to transthoracic echocardiography (TTE) for detailed assessment 1.
  • Contrast echocardiography using agitated saline can demonstrate right-to-left shunt indicative of PFO 1.
  • Management

  • Closure of PFO is indicated in recurrent paradoxical embolism or cryptogenic stroke with high suspicion of paradoxical embolism 1.
  • Device closure using percutaneous transcatheter methods is a common approach, though specific drug treatments are not detailed in the provided abstracts 1.
  • Surgical closure may be considered in cases where transcatheter methods are not feasible 1.
  • Special Populations

  • No specific guidance provided for pregnancy, pediatrics, elderly, or comorbidities related to PFO management in the given abstracts 1.
  • Key Recommendations

  • Use echocardiography, particularly TEE, for definitive diagnosis of PFO 1.
  • Consider percutaneous transcatheter closure for patients with recurrent paradoxical embolism or high-risk cryptogenic stroke 1 (Evidence: Moderate).
  • Powder-free gloves facilitate proper application of skin closure tapes post-procedurally, enhancing wound management practices 1 (Evidence: Expert opinion).
