Comparative StudyTranscatheter closure of patent foramen ovale in patients with paradoxical embolism: intermediate-term risk of recurrent neurological events.
Closure of patent foramen ovale (PFO) has been proposed as an alternative to anticoagulation in patients with presumed paradoxical emboli. We report our preliminary intermediate results of patients who underwent transcatheter PFO closure for paradoxical embolism using DAS-Angel Wings occluder or Amplatzer devices. Eighteen patients (8 male/10 female) underwent catheter closure of their PFOs at a median age of 42 years. ⋯ No complications were encountered either during or after the closure procedure. In conclusion, transcatheter closure of PFO seems to be an effective alternative therapy in the prevention of presumed paradoxical emboli. Further study is needed to identify patients most likely to benefit from this intervention.

Case ReportsIntracoronary retrieval of the dehisced radiopaque ring of a guiding catheter: an unusual complication of coronary angioplasty.
The guiding catheter used in coronary intervention may be damaged or some parts could be dehisced during the procedure, producing adverse effects in the vascular tree. So much so that immediate surgery is usually indicated. We report a case with a dehisced radiopaque ring of the catheter during the procedure. It was retrieved percutaneously without thoracotomy.
