“…There were no significant differences between left‐ and right‐sided shunts, origin and distal pulmonary artery growth, and the tetralogy of Fallot and pulmonary atresia with ventricular septal defect groups 34 . At a mean follow‐up of 45.29 months, the increase in diameter of the main, right, and left pulmonary arteries and pulmonary valve annulus was uniform and significant 35 . A modified B‐T shunt to the main pulmonary artery may promote more uniform growth of pulmonary artery branch 36 .…”

Background and aim of the study: Even though the Blalock-Taussig (B-T) shunt, either classic or modified, has been advocated and successfully employed in clinical practice for more than half a century, a systemic review on this procedure is still scanty. This warrants us a zest in making a comprehensive survey on this subject. Methods: Articles were extensively retrieved from the MEDLINE database of National Library of Medicine USA if the abstract contained information relevant to the B-T shunt in terms of the conduit options, modified surgical techniques, surgical indications, short-and long-term results, complications, and prognosis. Further retrieval was undertaken by manually searching the reference list of relevant papers. Results: Classical or modified B-T shunts, either on ipsilateral or contralateral side to the aortic arch, can be performed on patients of any age with minimum postoperative complications and low operative mortality. Expended polytetrafluoroethylene has gained satisfactory long-term patency rate in the construction of the modified B-T shunt. Excellent pulmonary artery growth was observed in the patients with a modified B-T shunt, and it has shown superb prognosis over the classic with regard to hemodynamics, patency rate, and survival. Conclusions: The modified B-T shunt that was developed on basis of the classic fashion remains the preferable palliative procedure aiming at enhancing pulmonary blood flow for neonates and infants with complicated cyanotic congenital heart defects. The modified B-T shunt is technically simpler with less dissection, and blood flow to the respective arm is not jeopardized. It has been proved to be of low risk, excellent palliation, and is associated with excellent pulmonary artery growth, has become the most effective palliative shunt procedure of today. doi: 10.1111/j.1540-8191.2008.00758.x (J Card Surg 2009;24:101-108) Complex cyanotic congenital heart disease may occasionally be unsuitable for surgical correction, but for palliative procedure only. 1 In 1945, prior

“…SAPAS's are used to 'grow' BPA's to facilitate total correction or optimal definitive palliation. In this regard, CS's have been shown to grow hypoplastic BPA's sufficiently in accordance with Nakata's recommendations (12). There appears to be conflicting evidence as to whether peripheral shunts (CBTS and MBTS) grow BPA's sufficiently (13,14); this may explain why surgical opinion and practice differ in regard to the most suitable shunt in a setting of hypoplastic BPA's.…”

Background: Congenital heart disease (CHD) is a significant cause of childhood morbidity and mortality worldwide. Treatment often involves systemic arterialto-pulmonary artery shunts (SAPAS); local data is sparse. Methods: A retrospective study was carried out at the Kenyatta National Hospital in Nairobi (Kenya) between January 1st 2006 and December the 31st 2012. All patients who received a SAPAS at the institution during the study period were included. Results: Twenty-four SAPAS were performed on 22 patients. Ten of 24 SAPAS's (41.7%) were central shunts and 14 of 24 SAPAS's (58.3%) were modified Blalock-Taussig shunts. The median age and median weight were 20 months (range 3-120) and 11.6 kilograms (range 4.7-23) respectively. The median pre-operative and postoperative arterial oxygen saturations were 68% (range:

“…Based on the patient group we studied, a right‐sided aortic arch with mirror imaging branching could be considered an anatomical variant associated with major cardiac disease. However, this anomalous arrangement of aortic arch and head and neck vessels may have an implication in the surgical management of these patients, especially when a Blalock Taussig shunt is necessary 8 . Although the diagnosis of conotruncal anomalies is made with echocardiography, CMR can add complimentary information to the evaluation of these patients, particularly in the 3D assessment of complex intracardiac anatomy, and is superior in visualizing the great vessel anatomy.…”
