Following a cryptogenic stroke, many patients are nowadays treated with the percutaneous closure of a patent foramen ovale (PFO), assuming that the aetiology of the stroke is secondary to a paradoxical embolism. After the PFO closure procedure a dual antiplatelet regimen is often prescribed for 3-6 months and several cardiologic and neurologic follow-up exams are scheduled in the first 12 months of follow-up. Usually a transthoracic +/- transoesophageal echocardiography (TTE +/- TEE) are performed at 6 months, however this kind of control is not systematically performed. In order to improve the clinical outcomes in this young patients' population, the investigators prospectively perform a complete cardiologic and neurologic follow-up program to all patients undergoing a successful percutaneous closure of a PFO.
The aim of these controls is to confirm the good position of the PFO-device, to confirm the absence of any residual right to left shunt or any significant atrial arrhythmias Furthermore this prospective follow-up will analyze the possible mechanisms leading to a cerebral stroke recurrence (e.g. size of the PFO, presence of an atrial septal aneurysm, presence of a residual shunt, size of the utilized closure device, ....).
At follow-up the following exams will be performed:
- at hospital discharge: chest X-ray +/- TTE + 7-days event loop record (ELR)
- at 6 months: clinical cardiologic and neurologic examination + TTE + TEE + 7-days ELR + trans-cranial doppler (TCD) with micro bubbles detection.
- at 1 year: clinical cardiologic and neurologic examination + TTE +/- TEE + 7-days ELR + trans-cranial doppler (TCD) with micro bubbles detection +/- cerebral MRI

Restoration of functions to the maximum degree possible in a person or persons suffering from a stroke.
Stroke caused by lacunar infarction or other small vessel diseases of the brain. It features hemiparesis (see PARESIS), hemisensory, or hemisensory motor loss.
A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)
A condition caused by the failure of body to dissipate heat in an excessively hot environment or during PHYSICAL EXERTION in a hot environment. Contrast to HEAT EXHAUSTION, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by DELUSIONS; CONVULSIONS; or COMA. It can be a life-threatening emergency and is most common in infants and the elderly.
