Patent foramen ovale and ascending aortic aneurysm causing the platypnea-orthodeoxia syndrome.

We describe a case of a 74-year-old woman who presented with new-onset hypoxia. A PFO and a dilated aorta causing POS were found on workup. Symptoms were resolved after undergoing percutaneous PFO closure. This case highlights the mechanism by which an ascending aortic aneurysm can alter hemodynamics through an existing PFO, leading to symptoms of a previously clinically insignificant PFO, and emphasizes how early recognition of POS allows for appropriate intervention.

This study investigated the interrelation between plasma D-dimer level, ILT volume, AAA size and progression.Main methodsThis was a retrospective observational study that involved 181 patients with infra-renal AAA. They were divided into small and large AAA groups according to AAA diameter. 24 of them had repeated abdominal computed tomography angiography (CTA) scan and were divided into slow-growing and fast-growing AAA groups according to the median value of AAA growth rate. Baseline and follow-up plasma D-dimer level, maximum diameter of AAA, total infra-renal aortic volume and ILT volume were analyzed.Key findingsPlasm...

AbstractBackgroundAbdominal aortic aneurysm (AAA) is a focal aortic dilatation progressing towards rupture. Non-invasive AAA-associated cell proliferation biomarkers are not yet established. We investigated the feasibility of the cell proliferation radiotracer, fluorine-18-fluorothymidine ([18F]FLT) with positron emission tomography/computed tomography (PET/CT) in a progressive pre-clinical AAA model (angiotensin II, AngII infusion).Methods and ResultsFourteen-week-old apolipoprotein E-knockout (ApoE−/−) mice received saline or AngII via osmotic mini-pumps for 14 (n  =  7 and 5, respectively) or 2...

Abstract Background: Atrial septal aneurysm (ASA) is a congenital deformity of the interatrial septum with a prevalence of 1-2% in the adult population. Although ASA has been supposed to be an incidental finding in echocardiographic examination, its structural and clinical associations have gained an increasing interest. Aim: To investigate and compare the clinical features and echocardiographic parameters between ASA patients and age- and gender-matched control group patients. Methods: 410 patients with ASA were enrolled in the study, prospectively. After the exclusion of 33 patients, the remaining 377 ...

W.L. Gore &Associates said today it won expanded FDA indications for its Cardioform septal occluder, now cleared for the closure of patent foramen ovale to reduce the risk of recurrent ischemic stroke in certain patients. The expanded application was supported by results from the Reduce study, which the Newark, Del.-based company said showed that closure of PFOs could significantly prevent recurrent ischemic stroke regardless of PFO anatomy. “With the FDA approval of the Gore Cardioform septal occluder for PFO closure, we can now provide physicians with one device that can be used for both ASDs and PFOs. The valu...

Conclusions These data confirm the aggressive aortopathy of LDS. Valve-sparing ARR should be performed when feasible to avoid the risks of prostheses. Serial imaging of the arterial tree is critical, given the rate of subsequent intervention.

We present a case of platypnea-orthodeoxia syndrome in a 85-year-old woman with patent foramen ovale, interauricular septal aneurysm and ascending aortic aneurysms who was admitted for an acute coronary syndrome which could be of embolic origin and was responsible for ventricular fibrillation during the transfer to the hospital. PFO closure was performed by percutaneous device and right coronary artery obstruction was treated by transluminal angioplasty and stenting. PMID: 26875900 [PubMed - in process]
