Platypnoea Orthodeoxia syndrome is defined by dyspnoea and hypoxaemia exacerbated by orthostatic positioning and alleviated in recumbency. This condition has been reported in association with pulmonary, hepatic and cardiac disease. We describe a case herein of a 79 year old female who developed severe hypoxaemia and dyspnoea post laparoscopic cholecystectomy. A difference in arterial blood gas oxygen tension was demonstrated in the supine and erect positions on arterial blood gas analysis. A Patent Foramen Ovale (PFO) with a right to left shunt was evident on echocardiogram employing colour doppler and agitated normal saline studies...

An 81-year-old female developed dyspnea only upon assuming a sitting position. Trans-esophageal echocardiography demonstrated left-to-right shunt flow across the atrial septum when the patient was sitting, and right-to-left shunt flow when she was supine, along with severe aortic insufficiency. She was diagnosed as having platypnea-orthodeoxia syndrome and her symptoms were completely resolved following aortic valve replacement, closure of a patent foramen ovale, and shortening of an elongated ascending aorta...

Patent foramen ovale (PFO), an embryonic remnant of the fetal circulation, is present in 20-25% of adults. While recent observational studies and clinical trials have established the link between PFO-mediated right-to-left shunting with cryptogenic stroke and migraine with aura, the role of a PFO in exacerbating hypoxemic medical conditions (i.e., sleep apnea, chronic obstructive pulmonary disease, pulmonary hypertension, platypnea-orthodeoxia, pulmonary arteriovenous malformation, high altitude pulmonary edema, and exercise desaturation) remains poorly evaluated...

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...
