Short And Moderate-term Follow-up After PFO Device Closure For PFO Complicated With Cryptogenic Stroke And/or Transient Ischemic Attack

Objective:To describe short and moderate-term follow-up of patients undergoing device closure of patent foramen ovale complicated with cryptogenic stroke and/or transient ischemic attack.Methods:We followed up 76 patients at Fuwai Hospital who successfully underwent device closure of PFO for secondary prevention of cryptogenic stroke/TIA from May 2009 to August 2016.All patients underwent transthoracic echocardiography(TTE),electrocardiogram,chest radiography at 24 hours,first month,third month,sixth month after closure and then received the phone call follow-up every half year.Results:For all of the 76 patients,71 were cryptogenic stroke and 5 were TIA.73 of the patients(96.1%)used an Occluder from STARWAY MEDICAL TECHNOLOGY.All of them took asprine after operation for six months.The mean follow-up was(35.34±23.46)months.No Recurrent stroke and/or TIA were reported.No right to left shunt was tested.Conclusion:Device closure of PFO can be performed safely with very good short and moderate-term secondary prevention from PFO related to cryptogenic stroke and/or TIA.
