Our goal was to review the effectiveness of the transseptal and tunnel techniques of patent foramen ovale (PFO) closure. Percutaneous PFO closure is an increasingly common treatment for prevention of paradoxical embolism and is typically performed by passing the device through the defect tunnel itself. The transseptal technique, in which the septum primum is punctured to create a hole through which the device is passed, has been proposed for patients with long-tunnel PFO. From May 2001 to December 2003, 120 patients underwent PFO closure at our institution and were included in this analysis. Defect closure was assessed by transesophageal echocardiography (TEE) with bubble study. Clinical follow-up data were obtained by clinic visits or standardized telephone interviews. Device closure was successfully completed in all patients, with 12 (10%) undergoing transseptal closure and 108 (90%) undergoing tunnel closure. Immediately following the procedure, complete closure occurred in 6 of 12 (50%) of the transseptal group and 88 of 108 (81.5%) of the tunnel group (P = 0.0120). Of the 89 patients (74.2%) who returned for 6-month TEE, complete closure was demonstrated in 4 out of 10 (40%) of the transseptal group and 58 out of 79 (73.4%) of the tunnel group (P = 0.0303). There have been four transient ischemic attacks during a mean follow-up of 11 months. The transseptal technique of PFO closure results in a higher proportion of patients with persistent interatrial shunting when compared with the tunnel technique. Whether this is due to a difference in technique, device, or patient anatomy is unclear. (c) 2005 Wiley-Liss, Inc.
