Abstract
It is unclear if neonatal tetralogy of Fallot repair offers better outcomes compared to repair later in infancy. We therefore conducted a meta-analysis comparing outcomes of neonatal and non-neonatal repair. Manuscripts were identified and reviewed for quality and bias with favorably scored manuscripts being included in the final meta-analysis. Several perioperative and postoperative variables were compared. A total of 8 studies with 3858 patients were included in the analysis. Of these patients, 19% underwent neonatal repair. Neonatal repair was associated with increased mortality, longer intensive care unit stays, and longer total hospital length of stay.

Abstract
Acute pulmonary edema developed in 2 patients after a Blalock-Taussig shunt procedure. Both patients had a univentricular heart complex with pulmonary stenosis. One patient underwent a modified Blalock-Taussig shunt using a polytetrafluoroethylene tube and the other underwent a classic Blalock-Taussig anastomosis. Acute pulmonary edema after the Blalock-Taussig shunt is rare, but once it has occurred, immediate treatment is obligatory.

Abstract
Surgical treatment for congenital heart disease has become available over the last five decades. Palliative procedures have been designed to improve physiologic abnormalities, for example systemic artery (or venous) to pulmonary artery shunts of various types to increase the pulmonary blood flow, pulmonary artery constriction (banding) to decrease the pulmonary blood flow, and surgical or transcatheter atrial septostomy to augment intracardiac mixing. These can be performed with a low mortality. The majority of congenital heart defects can be corrected by open heart surgical techniques; some require prior palliation and others can be operated without prior palliative surgery. Recent surgical advances include early total surgical correction for tetralogy of Fallot, arterial switch procedure for transposition of the great arteries, Fontan operation and its modifications for tricuspid atresia and single ventricle, new operations for hypoplastic left heart syndrome, newer prosthetic valves, myocardial preservation and cardiac transplantation.

Abstract
An aorta-pulmonary artery shunt with an expanded polytetrafluoroethylene (Gore-Tex) tube graft (3 to 6 mm in diameter) was done in 33 cyanotic patients with complex congenital heart disease. The patients ranged from 14 days to 22 years old. In 28, the shunt flow (QB) was measured, and the optimal QB and graft size were determined. Nine patients had severe heart failure because of an excessively large shunt. Seven of these patients died, 5 early and 2 late after operation. The QBS in these 9 patients were extremely high; the QB index and the ratio of shunt flow to systemic flow (QB/QS) were 3.86 +/- 0.91 L/min/m2 (mean +/- standard deviation) and 52.4 +/- 9.7%, respectively. The QB index and the QB/QS of patients without severe cardiac failure were 1.49 +/- 0.92 L/min/m2 and 27.2 +/- 11.4%, respectively. In conclusion, the QB index, the QB/QS, or both should be maintained in the range of 1.6 to 2.4 L/min/m2 and 30 to 40%, respectively. In infants, however, it is advisable to control the flow at less than the range just given. Analysis of graft size in relation to body weight (BW, in kilograms) and body surface area (BSA, in square meters) showed that the optimal diameter (D, in millimeters) could be calculated by the following formulas: D = 1.88 In(BW) + 1.8 (r = .86) D = 0.87 In(BSA) + 5.3 (r = .73).

Abstract
Results obtained with Blalock-Taussig, Waterston, and polytetrafluoroethylene (PTFE) shunts were compared in 67 cyanotic infants less than 2 weeks of age. A different shunt was preferably used at each of three institutions. The incidences of early shunt failure (3 out of 21, 14%), mortality after revision of early shunt failure (0 out of 3), and overall hospital mortality (1 out of 21, 5%) were all lowest for the PTFE shunt. Incidence of congestive heart failure secondary to excessive flow was comparable for the Blalock-Taussig and PTFE shunts, both of which were lower than the Waterston shunt. Cumulative probabilities of late shunt adequacy were calculated for hospital survivors. At 1 year, all shunts provided comparable adequate palliation (greater than 80%). Probability of late shunt failure was significantly higher (p = 0.04) for the PTFE shunt at 3.5 years. Results suggest that the PTFE shunt may be the safest and most effective shunt in neonates, but that elective shunt replacement or total repair may be warranted in the first or second year of life.

Abstract
Many Blalock-Taussig shunts (subclavian to pulmonary artery anastomoses) have been created and a significant number are still being done. Two cases of aneurysmal degeneration of a Blalock-Taussig shunt and their management are described. Development of this rare complication may be related to large shunt flow and long duration. Large, symptomatic or enlarging aneurysms should be repaired and smaller ones studied by serial computed axial tomography. A simple and safe approach to correct this lesion is division and oversewing of the proximal subclavian artery through an anterior approach, assuming adequate pulmonary blood flow is already present or can be established concomitantly.

Abstract
Thirty infants with various types of cyanotic congenitl heart disease underwent systemic-pulmonary artery shunts with a microporous polytetrafluoroethylene (PTFE) graft between May, 1976, and July, 1979. Sixteen of them were less than 1 month old, and the average age of the neonates was 5.3 days. There were no operative deaths and 5 hospital deaths, 2 related directly to the shunt. Five patients required early revision of the shunt. Relief from cyanosis was achieved in each patient. Twenty-five patients have been followed up to three and one-half years. There have been 2 late deaths and one late occlusion of the shunt. One patient outgrew the shunt and required secondary shunting procedures. Three of 30 patients have evidenced mild congestive heart failure, which has responded to digitalis. Because of the reliability and excellent late patency of the PTFE prosthesis, we consider it to be superior to a central or Potts shunt for relief from cyanosis in the neonate and infant, and as reliable as a Blalock-Taussig shunt.

Abstract
Fifteen of 194 patients (7.7%) with tetralogy of Fallot operated upon since January 1, 1972 under a protocol of routine primary repair despite young age died in-hospital. Most deaths were from low cardiac output. Young age and smallness of size increased the risk of operation. No deaths occurred among patients older than 4 years. High hematocrit was also a risk factor. Transannular patching has an independent effect in increasing risk. The post-repair ratio of peak pressure in the right ventricle to that in the left did not exert an independent effect. To project current risks of a two-stage approach, we determined that five of 158 patients (3.2%) died in-hospital after secondary intracardiac repair after a previous Blalock-Taussig or Waterston anastomosis between 1967--1978. Using these data and those we have published on the risk of shunting, we project that except in very small babies, the risks of hospital death of a two-stage approach are not less than those of primary repair done without a transannular patch, except when body surface area is less than about 0.35 m2. When a transannular patch is used in the primary repair, the two-stage approach is projected to be safer when the child has a body surface area of about 0.48 m2 or smaller.

Abstract
One hundred forty-nine consecutive patients with tetralogy of Fallot, with or without pulmonary atresia, underwent Blalock-Taussig or Waterston operation for initial palliation. Of these patients, 45 were less than 6 months old, and 63 were less than 1 year old. The type of shunt, and the presence or absence of pulmonary atresia did not have a significant effect (p greater than 0.2) on hospital mortality. Parametric analysis showed a significant effect of age (p = 0.03), the risk of hospital death being 6% at 1 month of age, 4% at 3 months, 3% at 6 months, and 2.5% at 12 months. No late deaths occurred before the age of 3 years. Six patients (4.2% of the hospital survivors) required another operation before they were 3 years old. Severe arm ischemia occurred after a Blalock-Taussig shunt in 1 infant with Down's syndrome.

Abstract
Six unselected neonates with cyanotic congenital heart disease and life-threatening degrees of arterial oxygen desaturation have been managed by a protocol that includes administration of prostaglandin E1 (PGE1) and early Blalock-Taussig shunting. In 5 patients (seven paired observations) partial pressure of arterial oxygen (PaO2) rose from 19 mm Hg to a mean of 32.9 mm Hg within 20 minutes of initiation of PGE1 (0.1 to 0.2 microgram/kg/hr), infused intravenously or through an aortic catheter placed at ductal level or with both methods. The nonresponsive patient was older than the patients showing a positive response (1 month versus 24 to 96 hours). Following catheterization, immediate palliative operation including a Blalock-Taussig shunt was carried out. Although all had a satisfactory PaO2 (mean, 49 mm Hg) postoperatively, the PGE1-nonresponsive patient experienced serious intraoperative bradycardia, hypotension, and acidosis in contrast to the PGE1-responsive group. In this study, the use of PGE1 was not associated with any apparent serious side effects.

Abstract
A cohort of 61 consecutive patients 24 months of age of younger had palliative shunts for symptoms of tetralogy of Fallot during a 12-year period. Thirty-six of these patients have been followed through definitive intracardiac repair or to death. For analysis palliative operations were separated into two six-year periods, 1965--1970. During the first period seven of 30 infants operated on died; all 31 infants operated on during the second period survived. The Waterston anastomosis was performed most frequently (67%) during the first period; the Blalock-Taussig anastomosis was performed in 68% of infants during the second period. Of 54 hospital survivors, three died before definitive intracardiac repair. Two of the three interim deaths were related to heart disease. Twenty-six of the remaining 51 patients have had definitive intracardiac repair with two deaths (8%). Twenty-four in this group had intracardiac repair since 1973 with one hospital death (4%). The cumulative mortality for the entire cohort is 25%, but more recent experience (1971--77) indicates a cumulative mortality near 5%. The recent mortality rate for staged management is less than the 14% rate reported by others for primary intracardiac repair of tetralogy of Fallot in 205 infants. We conclude that primary intracardiac repair has important advantages for infants with tetralogy of Fallot who have favorable anatomic features and no other associated cardiac lesions or medical problems. Staged management of tetralogy of Fallot is still recommended for infants with unfavorable anatomy, additional lesions or associated medical problems.

Abstract
Many surgeons have been reluctant to perform Blalock shunts in patients who are in infancy or early childhood (less than 24 months old) and have done instead direct aortopulmonary anastomoses. Recently, others have advocated complete repair of tetralogy of Fallot in early infancy because of the high mortality of direct aortopulmonary shunts. We believe the Blalock-Taussig anastomosis is a safe and effective palliative procedure for all infants with inadequate pulmonary blood flow regardless of size. During the past nine years, 24 babies less than 2 years old who were followed had construction of Blalock-Taussig anastomosis for inadequate pulmonary blood flow. There were no operative deaths and no shunt-related late deaths. Of the 24 babies, 12 were less than 12 months old. Eighteen of the 24 had tetralogy of Fallot. The remaining 6 had a variety of lesions with inadequate pulmonary blood flow. The mean weight of the entire group was 7.3 +/- 1.6 kg. Of those infants less than 12 months old, the mean weight was 6.8 +/- 2.0 kg. More than 6 months following construction of the shunt, 2 babies died from sepsis unrelated to cardiovascular status. All infants had adequate but not excessive pulmonary blood flow after shunting. There were no late shunt failures.

Abstract
In the last decade, 14 patients underwent an aorticpulmonary shunt for cyanotic heart disease, at which time the subclavian artery was either deemed too small or too short to function satisfactorily as a Blalock shunt. In each case a rectangular piece of pericardium was excised, rolled into a tube, and sutured down one edge to create a tube graft. One end of the graft was sutured to the stump of the subclavian artery near its takeoff and the other end was sutured end-to-side to the corresponding pulmonary artery. During the same period, 5 children had azygos vein grafts and 2 had Teflon grafts inserted to create a modified Blalock shunt. This article will discuss the indications, techniques, and long term results of aorticpulmonary shunts of all types, and more specifically the complications and long term results in patients where these grafts were used.
