Abstract:
We conducted a single center observational study aimed to assess safety and efficacy of Balmed Memopart PFO occluder in treatment of complex PFO anatomies including at least one of the following: tunnel length ≥ 8 mm, atrial septal aneurysm, lipomatous hypertrophy of fossa ovalis rims (≥10 mm), cribriform or additional multiple small defects on the fossa ovalis, residual large Eustachian ridge or Chiari network. This analysis demonstrated Memopart PFO occluder device to be a safe and effective option for PFO closure, with good procedural success rate (100 %) and no significant safety issues (1 mild residual shunt at 24 h).
