“Most bleeding events occurred in women, aligning with prior evidence. These results highlight the importance of tailoring antithrombotic therapy duration to individual factors, such as age, sex and cardiovascular risk profile, balancing ischemic protection against bleeding risk.”
“Long-term data is always important, but I would say in this particular group of patients, which are young patients, it's even more important because this is a population that is going to live for many years after the initial event. I think that it was important to have that data beyond 10 years in terms of safety and efficacy of the implanted device and in fact, it seems to be quite clear. This extends the observations of the randomized trials beyond 10 years and up to 17 years of follow-up, showing that really the rates of recurrent ischemic events are extremely low.”
Transcatheter PFO closure demonstrates excellent 20-year efficacy for stroke prevention, though long-term bleeding risks highlight the need for tailored antithrombotic management.
The results of this cohort study with 20-year follow-up showed the sustained very long-term safety and efficacy of transcatheter PFO closure, with less than 1% rate of recurrent stroke events. However, bleeding events occurred in about 1 in 10 patients and were more frequent in women and in patients under long-term antithrombotic therapy. These findings underscore the need for tailored long-term antithrombotic strategies after PFO closure. Further studies are warranted.
Vidal-Calés et al. (2026) studied this question. Transcatheter PFO closure shows sustained 20-year efficacy with under 1% recurrent stroke but 10% bleeding risk, especially in women and those on long-term antithrombotics.
