1/56. Reversible platypnoea and orthodeoxia after surgical removal of an hydatid cyst from the liver.

    A patient with a large hydatid cyst of the liver developed a positionally symptomatic right to left shunting across a patent foramen ovale with both platypnoea and orthodeoxia, despite normal pulmonary arterial pressures and normal pulmonary function tests. When the patient was in the supine position the calculated right to left shunt was 15.1% and 29.5% when seated. The shunt was attributed to the compression of the right atrium and ventricle by the cyst. Surgical evacuation of the cyst relieved the symptoms and the positionally induced shunting.

2/56. Closure of patent foramen ovale in patients with orthodeoxia-platypnea using the amplatzer devices.

    We present a series of four patients with orthodeoxia-platypnea who underwent successful transcatheter closure of their patent foramen ovale using the Amplatzer devices (Amplatzer septal occluder/Amplatzer PFO occluder). The average saturation increased from 81% to 96% with complete resolution of symptoms. The Amplatzer devices are safe and effective treatment options for patients with orthodeoxia-platypnea.

3/56. Platypnea-orthodeoxia syndrome related to an aortic aneurysm combined with an aneurysm of the atrial septum.

    We report the case of a 71-year-old man bearing a severe right-to-left shunt through a patent foramen ovale in the absence of elevated right-sided heart or pulmonary artery pressures. He presented with platypnea-orthodeoxia syndrome, but he had no pulmonary or extracardiac diseases that are known to be associated with this syndrome. Chest radiography showed a bulky aneurysm of the thoracic aorta. A peripheral contrast transesophageal echocardiography demonstrated a large right-to-left shunt through a patent foramen ovale. In addition, the atrial septum was severely deformed by an aneurysm including this patent foramen ovale. We hypothesized that the opening of the foramen ovale was the result of a mechanical deformation of the atrial septum by two contributing factors: the aneurysm of the thoracic aorta and the aneurysm of the septum itself.

4/56. Re-opened foramen ovale--a rare cause of postoperative dyspnea following pneumonectomy.

    dyspnea and hypoxemia are common postoperative problems following pneumonectomy. Platypnea, the increased dyspnea in the erect position relieved by assuming a prone position, has been reported as a result of right to left inter-atrial shunt. We report here on our experience with a patient who had severe platypnea with remarkable positional arterial desaturation following right pneumonectomy. After establishing the diagnosis with contrast-enhanced transesophageal echocardiography of the preoperatively undetected interatrial right-left shunt, cardiac surgery led to clinical improvement and resumption of platypnea. Given the rarity of the diagnosis, we think interatrial shunt, based on an open foramen ovale, should be taken into consideration when platypnea occurs in patients as a postoperative complication following lung surgery. Transesophageal echocardiography may be helpful in detecting patients with "anatomical closed but functional open" foramen ovale or genuine inter-atrial septal defect prior to lung surgery.

5/56. Orthodeoxia and platypnea secondary to a patent foramen ovale despite normal right-sided cardiac pressures.

    Numerous cases of orthodeoxia and platypnea have been reported. Some have been found to be due to intracardiac shunts despite normal intracardiac pressures. In the case presented, a 79-year-old woman was noted to have orthodeoxia and platypnea secondary to a patent foramen ovale (PFO) despite normal intracardiac pressures. She recovered after closure of the PFO. The authors postulate that recent vertebral fractures and subsequent kyphosis, as well as a dilated thoracic aorta, altered intrathoracic relationships and may have led to a stream of venous return being directed across the PFO in the upright position, despite normal intracardiac pressures.

6/56. meige syndrome secondary to basal ganglia injury: a potential cause of acute respiratory distress.

    BACKGROUND: meige syndrome is a movement disorder that includes blepharospasm and oromandibular dystonias. Its etiology may be idiopathic (primary) or it may arise secondary to focal brain injury. Acute respiratory distress as a feature of such dystonias occurs infrequently. A review of the literature on meige syndrome and the relationship between dystonias and respiratory compromise is presented. methods: A 60-year-old woman suffered a cerebral anoxic event secondary to manual strangulation. She developed progressive blepharospasm combined with oromandibular and cervical dystonias. neuroimaging demonstrated bilateral damage localized to the globus pallidus. Years later, she presented to the emergency department in intermittent respiratory distress associated with facial and cervical muscle spasms. RESULTS: Increasing frequency and severity of the disorder was noted over years. The acute onset of respiratory involvement required intubation and eventual tracheotomy. A partial therapeutic benefit of tetrabenazine was demonstrated. CONCLUSION: This case highlights two interesting aspects of Meige's syndrome: (1) Focal bilateral basal ganglia lesions appear to be responsible for this patient's movement disorder which is consistent with relative overactivity of the direct pathway from striatum to globus pallidus internal and substantia nigra pars reticularis; (2) Respiratory involvement in a primarily craniofacial dystonia to the point of acute airway compromise.

7/56. Carcinomatous lymphangitis mimicking pulmonary thromboembolism.

    A 41-year-old woman was admitted with rapidly worsening dyspnea. echocardiography disclosed interventricular septal flattening and a markedly decreased left ventricle, although left ventricular contraction remained normal. Computed tomography of the chest demonstrated slightly dilated main pulmonary arteries and fine reticulonodular densities in the lung. Examination of a transbronchial lung biopsy specimen revealed carcinomatous lymphangitis, and the patient died 7 days after admission. The clinical presentation of this patient was difficult to discriminate from that seen with pulmonary thromboembolism.

8/56. Patent foramen ovale presenting as platypnea-orthodeoxia: diagnosis by transesophageal echocardiography.

    Platypnea-orthodeoxia is a rare syndrome that is often associated with interatrial shunting through a patent foramen ovale or atrial septal defect. We describe the case of a 65-year-old woman with progressive dyspnea and hypoxia when standing and walking, which was relieved by assuming the recumbent position. The diagnosis was confirmed by tilt-table transesophageal echocardiography demonstrating a large right-to-left shunt through a patent foramen ovale while the patient was in a semiupright position and no significant shunt while in a recumbent position. This case demonstrates that platypnea-orthodeoxia caused by a patent foramen ovale can be clearly demonstrated by the technique of contrast transesophageal echocardiography performed on a tilt table.

9/56. Patent foramen ovale causing position-dependent shunting in a patient, when laying down her corset.

    A 75-yr-old female presented with platypnoea and orthodeoxia, shortly after laying down an old and pinching corset. The injection of activated Haemaccel in the right cubital vene during transoesophageal echocardiography, in the upright position, revealed a direct blood flow from the superior caval vein at a patent foremen ovale, consequently opening it and causing a large right-to-left shunt which was calculated at 28.5%. In the supine position there was only a minimal opening of the patent foremen ovale with a calculated right-to-left shunt of 9.5%. The patent foremen ovale was successfully closed percutaneously with a CardioSEAL.

10/56. Congenitally corrected transposition of the great arteries in a 65-year-old woman.

    A 65-year-old Japanese woman was admitted to hospital because of exertional dyspnea. Transthoracic echocardiography showed diffuse hypokinesis of the left-sided ventricular wall, but was not clear enough to provide useful information because of the rotation of the cardiac apex and the presence of lung tissue. Systemic ventriculography showed that the left-sided ventricle with heavy trabeculations was morphologically similar to a normal right ventricle. Magnetic resonance imaging (MRI) clearly revealed corrected transposition of the great arteries. Because this patient had no severe associated cardiac anomalies, systemic ventricular dysfunction is thought to be the major cause of exertional dyspnea. MRI is a useful non-invasive method for the rapid evaluation of cardiac morphology.
