OBJECTIVE: Cryptogenic stroke (CS) is considered to be the most common stroke subtype in young patients. The Risk of Paradoxical Embolism (RoPE) score is a tool that stratifies patients with CS according to the probability of patent foramen ovale (PFO). The aim of this retrospective study is to determine the prevalence of PFO in young patients with transesophageal echocardi- ography (TEE) and to evaluate the role of RoPE score in PFO-related strokes.
METHODS: The medical records of patients with acute arterial ischemic stroke, who underwent TEE between 2016 and 2020, were reviewed. Patients aged 18-55 years were included in the study. Presence of PFO, PFO characteristics, presence of atrial septal aneurysm (ASA) were detected by examining the image records of the patients from the archive system. RoPE score was calculated for all patients as determined in the literature.
RESULTS: Totally, 50 CS patients were included in the study (mean age: 39.6±9.4 years). PFO was detected in 19 (38%) patients and it was the most common cardiac abnormality in CS patients. ASA was detected in 7 (14%) patients. The mean RoPE score in patients with PFO was higher than patients without PFO, although it did not reach statistical significance (7.68±1.1 versus 6.77±1.9 P = .07). Eighteen of 19 patients with PFO had a RoPE score ≥7.
CONCLUSION: In our study, PFO prevalence in the CS patients was higher than normal popula- tion. In patients with cryptogenic stroke, the RoPE score can help determine the probability of PFO related stroke and which patients should undergo TEE.
