Russian Registry of Endovascular Closure of Patent Foramen Ovale

Observational National Medical Research Center for Cardiology, Ministry of Health of Russian Federation · NCT06156670

This study is looking at how closing a small hole in the heart called a patent foramen ovale (PFO) affects people over 18 who have had unexplained strokes, to see if it can help improve their health.

What this trial studies

This observational study involves patients over 18 years old who have undergone endovascular closure of a patent foramen ovale (PFO) across 29 medical centers in the Russian Federation. It aims to gather data on the relationship between PFO and cryptogenic strokes, which are strokes of undetermined origin. Participants will provide informed consent and personal data as part of their inpatient medical care. The study seeks to enhance understanding of PFO's role in ischemic events and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 who have experienced ischemic events linked to a PFO and can provide informed consent.

Not a fit: Patients who cannot receive antiplatelet therapy or have acute inflammatory diseases will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better management and treatment strategies for patients with cryptogenic strokes associated with PFO.

How similar studies have performed: Other studies have indicated a significant association between PFO and cryptogenic strokes, suggesting that this approach is supported by existing literature.
