ABSTRACT
Percutaneous patent foramen ovale (PFO) closure is a treatment for cryptogenic stroke and migraine headache. The goal of this study was to assess long-term outcomes of patients treated with percutaneous PFO closure. Records of patients with percutaneous PFO closure at Emory University Hospital from February 2002 to July 2009 were reviewed. Follow-up telephone questionnaire and chart review assessed recurrent stroke, migraine, and complications. Data was reviewed on 414 consecutive patients. Long-term follow-up was obtained in 207 of patients, and mean follow up was 4.6 ± 2.0 years. Cryptogenic stroke was the primary indication for intervention in 193 (93%) patients. Thirteen (7%) patients had a recurrent neurologic event post closure. In patients with multiple neurological events at baseline, 17% (n = 11) had a recurrent event, compared with 2% (n = 2) of patients with a single neurological event prior to PFO-closure (P < 0.002). Post closure, migraine frequency and severity declined from 4.5 to 1.1 migraine/month (P < 0.01) and 7.2 to 3.6 out of 10 (P < 0.01) in patients with history of migraine (n = 60). Thirty-day mortality was 1% (n = 2). One patient had device erosion 5 years post-procedure requiring emergent surgery. Atrial fibrillation was newly diagnosed in 8 (4%) patients within 6 months. In conclusion, the long-term rate of recurrent stroke after PFO closure is low in patients with a single neurological event at baseline. Serious long-term complications after PFO closure are rare. PFO closure may decrease the frequency and severity of migraine.

An 80-year-old woman was referred for transcatheter aortic valve implantation for correction of aortic stenosis. An echocardiogram at the author's institution revealed severe hypertrophy of the left ventricle with deep recesses into the myocardium and hypokinesis involving the left ventricular apex. In addition, there was subaortic stenosis secondary to a muscular ridge. The aortic valve was only mildly stenotic. In this Cardiology Grand Rounds, the authors present a rare case of ventricular noncompaction and review the literature on this subject and its association with other cardiac abnormalities.
