Long-term follow-up outcomes in a real-world study cohort after percutaneous patent foramen ovale closure Ahmet Hakan Ateş 1, Hikmet Yorgun 1, Uğur Canpolat 1, Yusuf Ziya Şener 1, Metin Okşul 1, Ergun Barış Kaya 1, Mehmet Levent Şahiner 1, Mehmet Akif Topcuoğlu 2, Ethem Murat Arsava 2, Kudret Aytemir 1 The aim of this report is to guide the optimal choice of treatment for TSFO in different clinical contexts.
