25. Double-outlet left ventricle. Echocardiographic diagnosis
This is a case report of a double-outlet left ventricle associated with tricuspid atresia and hypoplasia of the right ventricle, diagnosed during echocardiography with color-flow imaging, in a three-month-old child who presented with fatigue and cyanosis. The child underwent palliative pulmonary arterial banding without an invasive procedure, and showed sust

26. Pregnancy outcome and Ebstein's anomaly.
BACKGROUND--Ebstein's anomaly is an uncommon congenital cardiac abnormality that may be associated with cyanosis and arrhythmias. For those female patients with the anomaly who survive to adult life there is little information available about pregnancy, maternal complications, and fetal outcome. This study was designed to address this issue so that these pat

27. Intrapulmonary shunting in the biliary atresia/polysplenia syndrome: reversal after liver transplantation.
One hundred and seventy three children, including 93 with biliary atresia, received liver grafts at Addenbrooke's Hospital between 1983 and 1993. Of these, only seven developed cyanosis due to intrapulmonary shunting as a complication of their liver disease, and all seven of these had the biliary atresia/polysplenia syndrome. Intrapulmonary shunting was conf

28. Cyanosis After Surgical Correction of Pulmonary Valve Stenosis: An Old Problem Revisited
The presence of cyanosis following repair of congenital cardiac defects may result from several different mechanisms. We report two patients in whom early postoperative arterial hypoxemia manifested by cyanosis was caused by right-to-left interatrial shunting. Two-dimensional contrast echocardiography correctly identified the site and direction of shunting,

29. Variations in clinical presentation of Fallot's tetralogy in infancy. Angiographic and pathogenetic implications.
Striking variability has been observed in the presenting features in infancy of patients subsequently shown to have tetralogy of Fallot. Some patients presented with severe cyanosis in the neonatal period while others had a systolic murmur and cyanosis only on crying. In these latter patients cyanosis became present at rest over the subsequent months. Yet ot

30. Notifications of industrial chemical cyanosis poisoning in the United Kingdom 1961-80.
In 325 cases of industrial chemical cyanosis notified to Her Majesty's Factory Inspectorate for 1961-80 the incidence of poisonings showed considerable seasonal variation with substantially greater numbers occurring in the summer months. A correlation between the number of poisonings in any one year and the hotness of that summer was also shown. The vast maj

31. Increasing cyanosis early after cavopulmonary connection caused by abnormal systemic venous channels.
OBJECTIVE--To show that abnormal systemic venous channels in patients who undergo cavopulmonary anastomoses can become manifest and haemodynamically important only after surgery despite detailed preoperative investigation. DESIGN--Descriptive study of patients fulfilling the above criteria selected from hospital records over the past three years. SETTING--A

32. Methemoglobinemia Diagnosed as a Consequence of Cardiopulmonary Bypass
Clinically significant methemoglobinemia is rare and difficult to diagnose when other causes of cyanosis are likely. We report a patient in whom unstable angina pectoris and chronic obstructive pulmonary disease were assumed to be responsible for preoperative cyanosis. The use of cardiopulmonary bypass for aortocoronary grafting enabled the clinical diagnosi

33. Massive pulmonary arteriovenous fistula in the newborn.
Although pulmonary arteriovenous fistula as a cause of cyanosis is well recognized, most of the reported cases occur in older children and adults, and its importance as a correctable lesion in the newborn is often overlooked. The details of two babies who presented with cyanosis in the first few days of life are presented to emphasize that this eminently tre

34. Periarterial abscess: another cause of cyanosis after pulmonary artery banding.
Twenty seven months after pulmonary artery banding a boy aged two and a half developed rapidly progressive cyanosis. A periarterial abscess was found at the site of the band. Repair of the pulmonary artery and closure of the ventricular septal defect were complicated by profoundly low cardiac output and prolonged dependence on a ventilator. This near fatal c

36. UNUSUAL CASE OF PULMONARY ARTERIOVENOUS FISTULA CONCEALED BY THE CARDIAC SILHOUETTE ON CHEST ROENTGENOGRAM
A large pulmonary arteriovenous fistula was discovered in a patient with long-standing cyanosis, clubbing and dyspnea, with no other cardiovascular signs or symptoms and a normal chest roentgenogram at the time of cardiac catheterization and pulmonary angiography. The fistula was overshadowed by the cardiac silhouette. Surgical resection was successful. Alth
