Conclusion
In conclusion superiorly located PFO patients have a greater risk for stroke and may face different neurological problems in their rest of life,
percutaneous closure of superiorly located PFOs when detected will provide a life-saving process.
In recent studies the percutaneous PFO closure is suggested for some patients but the indication of closure is controversial.
Some authors suggests for closure immediately when detected while others defend for closure unless complications appears.
As recent technological improvements chance us to image PFO and its location radiologically,
these incomes give us to solve this clinical problem.
According to our study,
superior located patent foramen ovale is strongly associated with moderate stroke.
While superior located PFO causes more stroke risk than inferior located PFO,
we based it on hemodynamic factors caused intracardiac pressure by contractions in terms of systolic phase.
Our hypothesis is; in systolic phase,
openness of inferior located PFO narrows partially by contractions of muscle fibers which are located nearby inferior location.
In systolic phase the superior part of cardiac lumen pressure outcomes more than inferior locations to provide a successful ejection.
As a result superior located PFO expands and causes a potential risk for emboli.
Further studies needed to support our hypothesis.
In conclusion superiorly located PFO patients have a greater risk for stroke and may face different neurological problems in their rest of life,
percutaneous closure of superiorly located PFOs when detected will provide a life-saving process.
