Long term follow up after percutaneous closure of PFO in 357 patients with paradoxical embolism: Difference in occlusion systems and influence of atr…
2009
Abstract Background Percutaneous transcatheter closure of patent foramen ovale (PFO) in cryptogenic stroke or TIA is an alternative to medical therapy especially in patients with atrial septal aneurysm (ASA). The differences in time to complete occlusion for various closure devices in PFO alone and PFO plus ASA are of natural interest. Methods and results Between January, 1st 1998 and November, 30th 2006 percutaneous PFO closure was performed in 357 patients with a history of ≥1 paradoxical embolism using three different devices: Amplatzer PFO-( n =199), Starflex-( n =48) and Helex Occluder ( n =110). All patients were assigned to a post-interventional protocol with contrast-enhanced transe…
Iatrogenic pulmonary artery dissection in patient with ostium secundum interatrial septum defect
2020
Pulmonary artery dissection is a rare and lethal condition. Few cases are reported in the literature, and most are derived from autopsies. In most cases, pulmonary artery dissection is a complication of chronic pulmonary hypertension leading to pulmonary artery aneurysm but there are other causes. We describe a case of iatrogenic pulmonary artery dissection in an elderly patient with ostium secundum defect. In particular, we describe the role of cardiac magnetic resonance in making this diagnosis and guiding future therapeutic decisions.
Patent Foramen Ovale and Thromboembolic Complications
2010
The foramen ovale, an atrial septal defect which is essential in the fetal circulation, remains patent through adulthood in approximately 25% of the general population and so it represents the most common persistent abnormality of fetal origin. Patent foramen ovale (PFO) allows interatrial right-to-left blood shunting during those periods of the cardiac cycle in which the right atrial pressure exceeds the left one. An increasing number of pathological manifestations of PFO has been recently identified; among these, paradoxical systemic embolism, refractory hypoxemia in patients with right ventricular myocardium infarction or severe pulmonary disease, orthostatic oxygen desaturation in the r…
