Interventional cardiology
PFO Closure
Minimally invasive closure of a patent foramen ovale with a catheter-delivered device.
Overview
A PFO is a flap-like opening between the atria that persists after birth. Closure may be considered in carefully selected patients, particularly after an otherwise unexplained embolic stroke.
Who may be considered?
The decision requires neurological and cardiological evaluation to exclude other stroke causes and to assess whether the PFO is likely to be clinically relevant.
How is the procedure performed?
Through a femoral vein, a device is positioned on both sides of the opening and released under imaging guidance. Tissue gradually grows over the device.
Recovery and follow-up
Discharge is often possible the same or next day. Antiplatelet medication and follow-up imaging are prescribed; strenuous activity may be limited briefly.
Risks and safety
Bleeding, transient atrial arrhythmias, device-related clot, device displacement and residual passage are possible; the individual benefit must be weighed against these risks.
