Left atrial (LA) enlargement is a marker of LA cardiopathy and, in patients with patent
foramen ovale (PFO), is associated with an increased risk of ischemic stroke. The primary …

Background and Purpose Left atrial dysfunction has been reported in patients with patent
foramen ovale (PFO). Here we investigated the role of left atrial dysfunction in the …

Objectives: We postulate that, in patients with large patent foramen ovales (PFO) and atrial
septal aneurysms (ASA), left atrial (LA) dysfunction simulating “atrial fibrillation (AF)-like” …

Introduction Certain patent foramen ovale (PFO) characteristics, such as a large right‐to‐left
shunt (RLS) or atrial septal aneurysm, identify patients who may receive the highest clinical …

Background In patients with patent foramen ovale (PFO)–associated stroke, the presence of
large shunt or atrial septal aneurysm (ASA) has been suggested to convey a high risk of …

Background Τhe influence of atrial septal occluders in left atrial (LA) function after
percutaneous closure of patent foramen ovale (PFO) has not been thoroughly studied …

Background Patent foramen ovale (PFO) is implicated in the pathogenesis of clinical
conditions such as cryptogenic stroke and migraine with aura. This study evaluated the …

This study investigated anatomic and pathophysiologic variables that may determine which
patent foramen ovale (PFO) are associated with cerebrovascular accidents (CVAs) …

Background: Large patent foramen ovale (PFO), spontaneous right‐to‐left shunt, large atrial
septal aneurysm (ASA), coagulation abnormalities, and prominent eustachian valve (EV) …

Objective The clinical and echocardiographic parameters associated with the risk predictors
of cryptogenic stroke (CS) in patients with patent foramen ovale (PFO) still diverse and with a …
