Insights
Percutaneous closure of patent foramen ovale (PFO) using either the AMPLATZER or Figulla device is safe and effective. Both PFO closure devices demonstrated comparable long-term results for stroke patients.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Patent foramen ovale (PFO) is a potential cause of cryptogenic stroke.
- Percutaneous closure is a common treatment for PFO.
- Comparing different PFO occluder devices is crucial for clinical decision-making.
Purpose of the Study:
- To compare the acute and 12-month outcomes of percutaneous PFO closure using AMPLATZER and Figulla occluder devices.
- To evaluate the safety and efficacy of two distinct PFO closure devices.
Main Methods:
- An observational study involving 406 patients undergoing percutaneous PFO closure.
- Patients received either the AMPLATZER (n=179) or Figulla (n=227) device.
- Follow-up included clinical assessments and contrast transthoracic echocardiography at 24 hours, six months, and 12 months.
Main Results:
- High procedural success rates were observed for both devices.
- A comparable incidence of residual shunt (≥2 grade) at 12 months was noted (4.5%) regardless of the device used.
- The Figulla device showed a significantly lower rate of supraventricular arrhythmias (9% vs. 17%, p=0.02).
Conclusions:
- Percutaneous PFO closure with both AMPLATZER and Figulla devices is safe and effective.
- The choice of device may influence the rate of supraventricular arrhythmias post-procedure.
- Both devices offer comparable long-term efficacy in preventing residual shunts.
Aims:
The aim of this observational study was to compare acute and 12-month results of percutaneous closure of patent foramen ovale (PFO) with two occluder devices.
Methods And Results:
Between June 2007 and October 2014, 406 consecutive patients (48.1±13.3 years, 243 women) underwent percutaneous PFO closure with either the AMPLATZER (n=179) or the Figulla (n=227) device after a stroke or a transient ischaemic attack ascribed to the PFO. A right-to-left shunt grade >1 was previously detected in all patients and atrial septal aneurysm was present in 111 (27.5%) patients. Patients were followed up with a contrast transthoracic echocardiogram and clinically at 24 hours, six months, and 12 months after the procedure. A high procedural success was observed in both groups. Despite a trend towards a higher incidence of acute residual shunt immediately after device deployment among Figulla occluder patients, a residual grade ≥2 right-to-left shunt was observed in 4.5% of patients, independently of the device used for PFO closure. The only difference reported after Figulla device implantation was a lower rate of supraventricular arrhythmias (9% vs. 17%, p=0.02).
Conclusions:
According to this two-centre study, PFO closure appears safe and effective with the Figulla occluder as well as with the AMPLATZER device.
