A patent foramen ovale (PFO) is not to be considered a disease as it is present in about 25 % of people. Yet, it is the prime reason for paradoxical embolism that can cause serious problems, such as death, stroke, myocardial infarction, and peripheral ischemia. The frequency of such events is probably underestimated as other causes tend to be blamed for them. Device PFO closure can be easily accomplished as outpatient procedure with minimal discomfort and risk and it has been referred to as mechanical vaccination...

Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea-orthodeoxia syndrome in a young woman with acute atelectasis due to post-tuberculosis bronchial stricture. Imaging revealed complete middle and right lower lobe atelectasis with a partially aerated right upper lobe...

A 65-year-old woman with no significant prior medical history presented, in the postoperative course of a complicated cholecystectomy, several episodes of arterial desaturation. Pulmonary embolism was repeatedly suspected, but there was no evidence of pulmonary thrombus on the chest computed tomography angiographies obtained. As these episodes were mainly induced by postural changes, a platypnea-orthodeoxia syndrome was suspected. A transthoracic echocardiogram was performed and revealed a patent foramen ovale...

We report the case of a patient admitted to the Intensive Care Unit with dyspnea and refractory hypoxemia after surgical resection of a benign bronchogenic cyst. Etiological research approach excluded conventional postoperative hypoxemia causes. Thereafter a platypnea-orthodeoxia syndrome has been diagnosed. Additional tests will demonstrate the existence of a patent foramen ovale. This diagnosis was suitable with the patient's syndrome and was eligible for percutaneous closure procedure allowing immediate resolution of symptoms and confirming the diagnosis...

Hereditary hemorrhagic telangiectasia is a rare autosomal-dominant condition affecting visceral blood vessel development. Cerebral and most commonly pulmonary arteriovenous malformations are found in the majority of symptomatic patients. The most common complications include embolic strokes and cerebral abscesses, which have been attributed to abnormal vessel communications. Platypnea orthodeoxia is a rare condition that presents dyspnea and oxygen desaturation when adopting an upright position and is relieved on decubitus...

INTRODUCTION: Chilaiditi syndrome is a rare pathophysiology in which the colon or other organs are interposed between the diaphragm and liver, and respiratory or digestive symptoms sometimes manifest. Although there have been some cases of Chilaiditi syndrome complicating neuromuscular disorders, none have described resulting respiratory or digestive symptoms. CASE PRESENTATION: Our patient was a 20-year-old man with DMD who had been receiving noninvasive positive-pressure ventilation during the night...

Introduction Platypnea-orthodeoxia syndrome is a combination of positional dyspnoea and hypoxemia; it is caused by several cardiac, pulmonary and hepatic diseases. Case presentation In this study, we describe a 77-year-old female affected by unexplained dizziness and hypoxia that exacerbated in upright position. After diagnosing platypnea-orthodeoxia syndrome and excluding all possible causes (liver cirrhosis, acute and chronic pulmonary diseases and arteriovenous malformations), the origin of the syndrome was individuated in the presence of a patent foramen ovale with right-to-left shunt...

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...

An 83-year-old man was admitted with a chief complaint of exacerbation of dyspnea. His blood oxygen saturation was 90% in the recumbent position despite oxygen therapy, and it dropped to less than 80% when the patient attempted to sit upright. A computed tomography scan revealed a giant hepatic cyst compressing the right atrium and the inferior vena cava. After percutaneous drainage, the oxygen saturation improved and did not change with alteration of the patient's positions from recumbent to sitting or standing...

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...

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...

Platypnea-orthodeoxia syndrome (POS), the occurrence of dyspnea and arterial desaturation on changing from supine to sitting position, is a very rare phenomenon. Most case reports have been in association with an intra-atrial communication, and observation of this unusual physiological abnormality in pulmonary conditions has been extremely rare. We present a case of idiopathic pulmonary fibrosis where the patient developed characteristic symptoms of POS when it was complicated by Pneumocystis jiroveci pneumonia...

Background.: The presence of patent foramen ovale (PFO) has been linked to many illness, including cryptogenic stroke, transient ischemic attack, migraine, platypnea-orthodeoxia syndrome and decompression sickness in scuba divers. Transesophageal echocardiography is the gold standard technique for the visualization of atrial septal anatomy, but it is a secondary level exam, not always available, with additional associated costs and not completely free from procedural risks. Standard transthoracic echocardiography (TTE) has a too low sensitivity for PFO screening...

BACKGROUND: Platypnea-orthodeoxia syndrome is a rare syndrome characterized by dyspnea and hypoxia when the patient is sitting or standing. Here we report a case of platypnea-orthodeoxia syndrome caused by a right hemidiaphragmatic elevation with giant liver cyst that triggered a right-to-left shunt through the patent foramen ovale. This case report is the first presentation of a case secondary to hemidiaphragmatic elevation with giant liver cyst. In addition to this, a malposition of the pacemaker lead could be associated with platypnea-orthodeoxia syndrome in this case...

The plathypnea orthodeoxia syndrome is a rare condition that is characterized by dyspnea and hypoxia that occurs in the upright position and improves with recumbency. The diagnostic is often made tardively and requires the combination of two components: a mechanical one (for example a patent foramen ovale) and a kinetic one (for example COPD). This combination contributes to the blood flow through the communication. The treatment consists of closing the veno-arterial communication (in the case of a patent foramen ovale, the closing of the inter-atrial septum) (Knapper et al, 2014)...

A 77-year-old woman developed dyspnea over three years which occurred during sitting, standing or walking. Her physical examination, chest X-ray, ECG and cardiac catheterization results were all normal. A marked fall in arterial oxygen saturation was observed on sitting or standing. Transesophageal echocardiography showed an increase of right to left shunt flow on sitting. The patient was diagnosed with platypnea-orthodeoxia syndrome and underwent the surgical closure of an atrial septal defect of 19 mm in diameter...
