Case Sharing | Long-Tunnel PFO Closure with MemoSorb Biodegradable Occluder

30-Year Migraine Relief & 1-Year Follow-Up: Long-Tunnel PFO Closure with MemoSorb Biodegradable Occluder

Today, we share a remarkable case highlighting 1-year post-op outcomes of MemoSorb in treating a complex long-tunnel PFO (12mm length, 1.4mm width), with a focus on serial echocardiographic evidence of device degradation and clinical symptom resolution.

Case Highlights

Patient Profile: 53F, 30-year history of migraines (often unilateral, lasting hours to days), 2 syncopal episodes.

Diagnosis: Positive bubble study.

Implant: 2424 MemoSorb® biodegradable PFO occluder deployed under echo and DSA guidance.

Key Follow-Up Imaging Findings

Day 1 to 9 Months:

No residual shunt observed.

Gradual reduction in device echogenicity.

1-Year Echo:

No visible disc structures – replaced by 8mm tissue thickening at the septal implant site.

Zero residual shunt (rest or post-Valsalva).

Complete device absorption confirmed.
