Abstract:

We present a case report of successful transcatheter closure of patent foramen ovale (PFO) by transcatheter suturing device «Noblestitch EL».

Materials and methods: cryptogenic stroke may be the consequence of the PFO. Percutaneous PFO closure, being less invasive than surgical closure, is increasingly performed; there are, however, early and long-term risks including: device embolization, fracture, thrombosis, infection, erosions of free atrial wall, arrhythmias. Furthermore, device implantation may complicate future percutaneous access to the left atrium. Partially reabsorbable devices and tissue welding to close PFO have recently been introduced. We present a case report of 33-year-old woman with a history of cryptogenic stroke. Echocardiography imaging with bubble study demonstrated a right-to-left shunt through the PFO at rest. The right femoral vein was cannulated. A «Noblestitch EL» device was advanced across the PFO and thread was passed through the septum primum and secundum. Threads were exteriorized and a knot was advanced to the right atrial septum and cut.

Results: successful closing of PTO was confirmed by transesophageal echocardiogram. Later it was shown complete PFO closing, no right-to-left shunt, even during the Valsalva maneuver, no residual shunt was observed.
