Same-day discharge after percutaneous closure of persistent foramen ovale using intracardiac echocardiography and the Gore Septal Occluder.

Aim: Periprocedural and postinterventional care of patients undergoing closure of patent foramen ovale (PFO) varies significantly across care providers. Same-day discharge (SDD) after transcatheter interventions is an evolving concept. This study aimed to assess the same-day discharge rate and incidence of complications in patients undergoing PFO closure with intracardiac echocardiography (ICE) using the Gore®Cardioform Septal Occluder (GSO) device. The secondary aim was to analyse the efficacy of femoral vein closure with Perclose ProGlide.
Methods: Patients who underwent PFO closure with the GSO device at a university hospital in Stockholm, Sweden, were retrospectively included between March 1, 2017, and June 30, 2020, all with cryptogenic stroke as the indication for the procedure. All patients underwent PFO closure with conscious sedation and local anaesthesia. The indication for all patients was a cryptogenic stroke. Periprocedural imaging was performed using ICE and fluoroscopy in all patients. Patient characteristics and periprocedural data were collected from patient charts. Patients were kept on bed rest for 4-6 h post-intervention. Transthoracic echocardiography and clinical examination, including groin status, were performed before discharge. No clinical routine follow-up was performed the day following the intervention. Clinical follow-up was done by phone call two weeks after the procedure, and echocardiographic follow-up was done after 12 months. Data were analysed using linear and logistic regression models.
Results: In total, 262 patients were included, of which 246 (94%) had SDD. 166 patients (63%) received the ProGlide™ system for femoral vein access closure. Post-procedural arrhythmias occurred in 17 (6%) patients, and vascular complications in 9 patients (3%). The overall closure rate at follow-up was 98.5%. 25 out of 264 patients (9.5%) had to be readmitted within the first eight weeks after PFO closure, 16 due to atrial fibrillation warranting electric cardioversion, one due to an arteriovenous fistula that was operated, four due to chest pain/pain at the access site, and four patients developed fever. There was no difference in SDD among patients who received ProGlide™ vs. patients who did not receive ProGlide™.
Conclusion: SDD appears safe after transcatheter PFO closure with the GSO device with high procedural success rates. Low rates of complications and readmissions make the intervention suitable for this patient-friendly and cost-effective concept.
