Outline of Final Research Achievements |
This study aimed to evaluate the efficacy of saline contrast transthoracic echocardiography (TTE) for identifying PFO associated with cryptogenic stroke(CS). Contrast TTE showed that right-to-left shunt of Grade 4 was more frequently observed in patients with CS. Right-to-left shunt of Grade 4 was associated with multiple anatomical characteristics of high-risk PFO. These findings suggest that contrast TTE can be effective to stratify patients for transcatheter PFO closure.

Academic Significance and Societal Importance of the Research Achievements |
PFOは多くの健常人にも認めるため、奇異性脳塞栓症を発症し得るPFOであるか否か、判断することが重要である。本研究は、汎用性が高い経胸壁心エコー図で、奇異性脳塞栓症に関連するPFOを特定する方法を明らかにした。本研究の結果は、PFOカテーテル閉鎖術を考慮する患者選択において、非常に重要なエビデンスになり得ると考える。
