Why the study?
Is transcatheter closure of patent foramen ovale via the transfemoral approach feasible in patients with previously placed inferior vena cava filters?
Is transcatheter closure of patent foramen ovale via the transfemoral approach feasible in patients with previously placed inferior vena cava filters?
Transcatheter PFO closure via the transfemoral approach may be performed in patients with previously placed IVC filters despite initial concerns of filter dislodgment.
Answers are grounded in this paper and cite their sources.
Supports feasibility of transfemoral PFO closure despite IVC filters; hypothesis-generating and should not yet change practice.
We present three patients with cryptogenic stroke who underwent transcatheter closure of a patent foramen ovale. All patients have had history of deep venous thrombosis and pulmonary embolism with placement of inferior vena caval filters. The patients were not initially considered suitable candidates for the procedure because of risk of dislodgment of previously implanted inferior vena cava filter.
