Trepopnea due to interatrial shunt following lung resection.
Dyspnea and platypnea following pneumonectomy have been reported as a result of right-to-left interatrial shunt. We report on a case of trepopnea with marked positional arterial oxygen desaturation following right middle and lower lobectomy. A similar mechanism was found, with right-to-left interatrial shunting occurring predominantly in the right lateral position. Surgical repair corrected the...
متن کاملDyspnoea and hypoxaemia after lung surgery: the role of interatrial right-to-left shunt.
After lung surgery, some patients complain of unexplained increased dyspnoea associated with hypoxaemia. This clinical presentation may be due to an interatrial right-to-left shunt despite normal right heart pressure. Some of these patients show postural dependency of hypoxaemia, whereas others do not. In this article, the pathogenesis and mechanisms involved in this post-surgical complication ...
متن کاملRight to left shunt through interatrial septal defects in patients with congenital heart disease: results of interventional closure.
OBJECTIVE To study the effects of closure of interatrial communications associated with a right to left shunt in patients with congenital heart disease (CHD) who had a biventricular repair. DESIGN Retrospective study. SETTING Tertiary referral centre. PATIENTS 15 patients with CHD with right to left shunt through an interatrial communication: three had repaired tetralogy of Fallot, five h...
متن کاملHypoxemia secondary to right-to-left interatrial shunt through a patent foramen ovale in a patient with an elevated right hemidiaphragm.
Though uncommon, right-to-left shunt through a patent foramen ovale with normal right-side pressure and with a normal interatrial pressure gradient has been reported. The speculated pathophysiology is attributed to directional blood flow streaming from the vena cava to the left atrium. Hypoxemia secondary to right-to-left shunt with normal pulmonary artery pressure has been extensively document...
متن کاملDynamics of interatrial shunting in children with obstruction of the tricuspid and pulmonic valves.
The interatrial pressure-flow dynamics in patients with right-to-left shunting at the atrial level in the presence of right heart obstruction were studied. In tricuspid atresia most of the right-to-left gradient occurred during right atrial systole. This gradient, as well as the cineangiocardiograms, indicated that almost all systemic venous return was transferred from the right to the left atr...
