Humans with a patent foramen ovale (PFO) have a higher esophageal temperature (Tesoph) than humans without a PFO (PFO-) . Thus, the presence of a PFO might also be associated with differences in thermal responsiveness to passive cooling and heating, such as shivering and hyperpnea, respectively. The purpose of this study was to determine if thermal responses to passive cooling and heating are different between PFO- subjects and subjects with a PFO (PFO+). We hypothesized that compared to PFO- subjects, PFO+ subjects would cool down more rapidly and heat up slower, and PFO+ subjects that experienced thermal hyperpnea would have a blunted increase in ventilation...

BACKGROUND: Cerebellar infarction is an uncommon but serious cause of isolated acute vestibular symptoms, particularly in young, healthy individuals, and can easily be overlooked. We present two cases of cerebellar infarction in U.S. Air Force pilots, one of which occurred during flight. CASE REPORTS: A 41-yr-old man developed acute vertigo, disequilibrium, nausea, and headache, with progressive slow symptomatic improvement, and presented to medical attention 4 d after symptom onset...

BACKGROUND: Platypnea-orthodeoxia syndrome (POS) is an uncommon disorder characterized by dyspnea (=platypnea) and desaturation (=orthodeoxia) in upright position and improvement of symptoms and blood oxygenation in supine position. Clinical presentation is heterogeneous and often confuses the clinician. OBJECTIVES: The present case report illustrates a complicated presentation of the underlying syndrome. METHODS: Description of a POS case in a 73-year-old female with thorough workup and tailored treatment...

PURPOSE: To present a novel endovascular management option that avoids open surgery in selected patients with subacute type A aortic dissection (DeBakey II). CASE REPORT: A 75-year-old woman with previous infrarenal abdominal aortic aneurysm repaired in 2006 and multiple comorbidities (EURO score II 20.5%) was admitted with chest pain; computed tomography angiography (CTA) showed a new dissection in the ascending aorta just above the right coronary ostium. As the patient was considered unfit to undergo surgery, an endovascular solution was suggested after multidisciplinary team discussion...

Paradoxical embolism is a known complication with intra-cardiac shunts. It should be considered in the differential as the pathophysiologic mechanism of simultaneous thromboembolism in the venous and systemic vasculature. We present a case of simultaneous deep venous thrombosis, pulmonary embolism and myocardial infarction in the presence of a confirmed patent foramen ovale on echocardiography. Thrombolytic therapy was administered. Subsequent concerns of intracranial hemorrhage on imaging of the brain complicated the management and added to the challenge of co-managing the clot burden in our patient...

Researchers have identified a subset of Holstein having a range of skeletal deformities, including vertebral anomalies, referred to as complex vertebral malformation due to mutations in the SLC35A3 gene. Here, we report the first case in humans of SLC35A3-related vertebral anomalies. Our patient had prenatally diagnosed anomalous vertebrae, including butterfly, and hemivertebrae throughout the spine, as well as cleft palate, micrognathia, patent foramen ovale, patent ductus arteriosus, posterior embryotoxon, short limbs, camptodactyly, talipes valgus, rocker bottom feet, and facial dysmorphism including proptosis, nevus flammeus, and a cupped left ear...

Patent foramen ovale has been associated with multiple pulmonary diseases, such as pulmonary hypertension, platypnea-orthodeoxia syndrome, and chronic obstructive pulmonary disease. A connection between patent foramen ovale and chronic pulmonary disease was first described more than 2 decades ago in case reports associating patent foramen ovale with more severe hypoxemia than that expected based on the severity of the primary pulmonary disease. It has been suggested that patients with both chronic pulmonary disease and patent foramen ovale are subject to severe hypoxemia because of the right-to-left shunt...

A ductus arteriosus aneurysm (DAA) was corrected with an 18 mm Amplatzer patent foramen ovale occluder. DAA is a rare finding, with sporadic cases reported (the vast majority in children and infants). In the elderly, it poses serious therapeutic challenges, as the risk of rupture is counterbalanced by the high risk of its correction, which requires surgery or placement of an endovascular prosthesis in a critical region such as the aortic arch.

Percutaneous transcatheter closure of a patent foramen ovale (PFO) remains challenging when femoral venous approach is not available. We describe the successful closure of a PFO using the right internal jugular venous approach and a catheter delivery system with a reshaped tip in a patient with a PFO, recurrent stroke, recurrent gastrointestinal bleeding, bilateral deep venous thrombosis and thrombosed bilateral inferior vena cava filter.

BACKGROUND: The association between patent foramen ovale (PFO) and migraine with aura (MA) is well established. However, the benefits of PFO closure are less certain in patients with migraine without aura (MwoA). METHODS: We systematically searched Pubmed for pertinent clinical studies published from January 2000 to July 2015. The primary end-point was the elimination or significant improvement of migraine symptoms after PFO closure. RESULTS: Upon screening an initial list of 315 publications, we identified eight studies that included 546 patients...

A rare adverse event of a right-sided pneumectomy with an elevated hemidiaphragm is right-to-left shunting through a patent foramen ovale. In this case report we describe our experience with plication of the right hemidiaphragm with instantaneous hemodynamic results and pain relief, followed by secondary closure of the foramen ovale.

Cerebral embolism is typically caused by a cardiogenic thrombus. The patent foramen ovale is a well-known cause of paradoxical embolism. However, some idiopathic cases of stroke have been reported. Such strokes are designated as embolic stroke of undetermined sources. Among them, lung lobectomy may be a new embolic risk factor for cerebral embolism. The risk of thrombus formation is high at the pulmonary vein stump after lung lobectomy, especially in the left upper lobe. Interestingly, the risk remains several years after surgery...

Platypnea-Orthodeoxia syndrome (POS) is a rare clinical entity characterized by dyspnea and arterial desaturation while in the upright position. The various pathophysiologic mechanisms leading to POS has puzzled clinicians for years. The hypoxia in POS has been attributed to the mixing of the deoxygenated venous blood with the oxygenated arterial blood via a shunt. The primary mechanisms of POS in these patients can be broadly classified based on intracardiac abnormalities, extracardiac abnormalities and miscellaneous etiologies...

Atrial fibrillation (AF) is a really uncommon arrhythmia in newborns. Here, we report the case of a 1-day-old infant who was recovered in Neonatal Intensive Care Unit for a twin-to-twin transfusion. The appearance of an unexpected AF was registered at his continuous electrocardiographic monitoring. Both chest X-ray and echocardiographic examination revealed the anomalous insertion of the tip of a central venous catheter (CVC) into the heart ('umbilical artery → inferior vena cava → right atrium → patent foramen ovale → left atrium')...

J David Spence
Recent advances in secondary stroke prevention include new evidence in hypertension, nutrition, anticoagulation, antiplatelet therapy, intracranial stenosis, percutaneous closure of patent foramen ovale, and lipid-lowering therapy. Individualized therapy for hypertension based on phenotyping with plasma renin and aldosterone markedly improves blood pressure control in patients with resistant hypertension. A Mediterranean diet can reduce the risk of stroke by nearly half. The diagnosis and treatment of metabolic vitamin B12 deficiency, and B vitamins to lower homocysteine, can reduce the risk of stroke by approximately 30%...

Background The aim of this study was to compare the immediate and long-term clinical outcomes of medical therapy and percutaneous patent foramen ovale (PFO) closure as secondary prevention strategies in patients younger than 55 years of age presenting with cryptogenic stroke and PFO. Methods Between January 2006 and April 2015, all patients with the diagnosis of cryptogenic stroke and PFO were analysed and prospectively followed. Stroke was confirmed in 159 out of 309 patients (51%). In the remaining cases, other neurological conditions were found and therefore excluded from further analysis...

A 3-month-old female with ventricular septal defect underwent definitive repair. In the operation, a venting tube was inserted through the incised patent foramen ovale. The ventricular septal defect was closed using a patch and the incised patent foramen ovale was directly closed. A transesophageal echography showed no abnormal findings in the operating room. On 1st postoperative day, the patient's heart rate and pressure of the superior vena cava increased while blood pressure decreased. A transthoracic echocardiography revealed an atrial septal hematoma...

INTRODUCTION: A association between partial anomalous pulmonary venous connection (PAPVC) and systemic venous anomalies has been described in the literature, but the true incidence is yet to be elucidated. At our institution, we sought to find the incidence of a persistent left superior vena cava (PLSVC) in patients undergoing an operation for PAPVC. METHODS: A retrospective review of all pediatric and adult patients with PAPVC who underwent surgical repair from February 2006 to February 2016...
