Device Closure for Patent Foramen Ovale
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two devices, the Amplatzer and NobleStitch EL, to determine which is more effective at closing a hole in the heart called a Patent Foramen Ovale (PFO). Closing a PFO can help prevent strokes caused by blood clots passing through this hole. The trial seeks individuals who have experienced a stroke or mini-stroke and have a PFO or similar heart conditions. Participants will assist researchers in comparing the effectiveness and safety of these two devices in closing the heart defect. As an unphased trial, this study provides participants the chance to contribute to important research that could enhance future heart treatments.
What prior data suggests that these devices are safe for PFO closure?
Research has shown that both the Amplatzer and NobleStitch EL devices are promising for safely closing a Patent Foramen Ovale (PFO), an opening in the heart that should close after birth.
For the Amplatzer device, studies indicate it is very safe, with only about a 1.5% chance of stroke recurrence over nine years post-procedure. Most people tolerate the device well, although those with nickel allergies might experience some issues.
The NobleStitch EL device also has a strong safety record. Recent data show no device-related problems, such as irregular heartbeat or repeated strokes, in a large group of patients, suggesting it is well-tolerated over time.
Both devices have been studied for their ability to safely close the PFO and prevent future strokes. The evidence so far supports their safety for those considering joining a trial.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the treatments Amplatzer and NobleStitch EL because they offer unique methods for closing patent foramen ovale (PFO), which is a hole in the heart that didn't close the way it should after birth. Unlike most standard treatments that involve more invasive surgical procedures, these devices provide a minimally invasive approach. The Amplatzer device acts like a tiny plug that seals the hole, while the NobleStitch EL uses a stitch-based technique to close the PFO. These innovative methods aim to improve patient outcomes by reducing recovery times and potentially lowering the risk of complications compared to traditional surgical options.
What evidence suggests that these devices are effective for closing Patent Foramen Ovale?
This trial will compare the effectiveness of two devices for closing a patent foramen ovale (PFO): the Amplatzer PFO Occluder and the NobleStitch EL. Research has shown that the Amplatzer PFO Occluder effectively closes PFOs in 98.9% of cases without major complications, reducing the risk of another stroke to 1.5% over nine years. Meanwhile, studies indicate that the NobleStitch EL closes PFOs in 94% of patients with good positioning, achieving a closure rate of 89% and complete closure in 75% of cases. Both devices show promise in preventing future strokes in patients with PFOs.12367

Are You a Good Fit for This Trial?
The STITCH trial is for adults aged 18-65 with specific heart conditions: small Atrial Septal Defect (ASD) or Patent Foramen Ovale (PFO). It's suitable for those who've had a stroke, transient ischemic attack (TIA), or certain decompression illnesses. People under 18, over 65, or not fluent in English can't participate.Inclusion Criteria

Experimental Treatment
Active Control
Evaluate closure rate of clinically relevant septal defects including PFO, ASD (less than 1 cm with redundant septal tissue), transseptal puncture sites, repair of ASA (when an appropriate PFO or small ASD defect is present), and rate of a recurrent neurologic embolic event in patients with cryptogenic stroke and PFO.
