Migration of PFO closure device and entrapment within tricuspid valve
leading to tricuspid regurgitation: Surgical correction of an extremely
rare complication after transcutaneous PFO closure
Abstract
A 41-year-old lady was referred to tertiary cardiothoracic surgery
centre following embolisation of patent foramen ovale (PFO) closure
device to septal leaflet of tricuspid valve with reopening of PFO. Two
years earlier, she presented with thalamic stroke, and she was found to
have a PFO following investigations. The following year she underwent
transcatheter closure. Six months after the percutaneous closure, she
presented again with significant periods of shortness of breath. Imaging
studies revealed the migration and embolisation of PFO closure device to
the septal leaflet of tricuspid valve with reopening of the foramen and
significant tricuspid valve regurgitation. She underwent open heart
surgery using cardiopulmonary bypass for retrieval of the device,
closure of the foramen and repair of the tricuspid valve. The patient
recovered well without any significant issues following surgery.
