“…The need for early surgery, especially in cases with indication of univentricular repair is mandatory and advocated by several centers around the world [6,7,9,14]. The main objective is to restore adequate flow to both pulmonary arteries.…”

“…Surgical correction with enlargement of the coarctation area using autologous pericardium is performed by several groups [6,7,9]. The surgery is usually performed with cardiopulmonary bypass, which leads to an exacerbation of the inflammatory response with increased hospital stay and complications [10].…”

“…The completion of correction of coarctation of the pulmonary artery allows proper development of the pulmonary tree, favoring the vascularization and maintenance of low resistance in the pulmonary arteries [7]. With the delay of surgical treatment, future procedures may be more complex and with less favorable outcomes due to the underdevelopment of the lung, which receives less blood flow [8].…”

“…Currently, the treatment of coarctation of the pulmonary artery has been accomplished even in the neonatal period and with use of cardiopulmonary bypass in several centers around the world [6,7,9]. The use of cardiopulmonary bypass in the neonatal period causes to the child a large inflammatory stimulation and can double its intravascular blood volume [10].…”

Tática para cirurgia de correção da coarctação da artéria pulmonar sem uso de circulação extracorpóreaApproach for surgical correction of pulmonary artery coarctation without cardiopulmonary bypass Abstract Pulmonary artery coarctation often happens in patients with pulmonary atresia. The correction is usualy on bypass and in the neonatal period, influencing pulmonary artery development and patient prognosis. Three patients with pulmonary atresia depending of PDA where corrected using median sternotomy without cardiopulmonary bypass. The PDA maintained the arterial saturation during Blalock Taussig anastomoses upon the other pulmonary artery. Pulmonary arterioplasty was performed using an autologous pericardium with 7-0 PDS running suture and saturation maintained by Blalock shunt. All patients had good follow up and where discharged with good enlargement of coarctation area.Descriptors: Pulmonary artery. Pulmonary atresia. Heart defects, congenital. Cardiopulmonary bypass.

“…This anomaly is present in ~67% of patients with pulmonary atresia and in ~10% of cases with pulmonary stenosis [35]. It is important to identify this anomaly prior to any planned aortopulmonary shunt, as early correction (ideally at the time of aortopulmonary shunt placement) has a great impact on future PA development [36].…”

The ductus arteriosus is a normal vascular structure in mammalian embryos that connects the main pulmonary artery (MPA) with the descending aorta or a subclavian artery. In left aortic arch the ductus arteriosus inserts into the proximal descending aorta at its junction with the aortic isthmus, distal to the origin of the left subclavian artery. In right aortic arch the ductus arteriosus can connect the right descending aorta with the MPA (right-sided ductus arteriosus), the proximal left subclavian artery with the MPA (left-sided ductus arteriosus), or both (bilateral ductus arteriosus). In the fetus, the ductus arteriosus carries blood from the right ventricle (RV) to the aorta, bypassing the high-resistance pulmonary vascular bed. Normally, the ductus arteriosus closes during the first day of life. Persistent ductal blood flow beyond the newborn period is termed patent ductus arteriosus (PDA). IncidenceThe incidence of PDA varies considerably depending on the postnatal age of subjects and their degree of prematurity. PDA is common in preterm infants and is considered a functional abnormality as opposed to a structural congenital cardiac anomaly. In term infants the normal ductus arteriosus may stay open for several days after birth. Echo-Doppler studies in healthy newborns have shown functional closure of the ductus arteriosus in almost all subjects by 4-7 days after birth [1,2]. Based on analysis of 40 published articles spanning several decades, Hoffman and Kaplan estimated the median incidence of PDA in term infants at 56.7 per 100 000 live births [3]. EtiologyThe etiology of isolated PDA in full-term infants older than 1 week is not known. Recent investigations have identified the genes affecting the development of the fourth and sixth pharyngeal arches, and noted their association with cardiovascular defects similar to those observed in DiGeorge syndrome [4]. Morphology Developmental considerationsThe normal anatomy and congenital malformations of the ductus arteriosus and branch pulmonary arteries are rooted in the development of the embryonic sixth aortic arches (see Chapter 30). The embryo has two dorsal aortas, which communicate with the ventrally located aortic sac via several pairs of branchial arch arteries. During development, there is an orderly appearance and regression of six pairs of primitive aortic arches. The fate of the fourth and sixth arches is most important to the topics covered in this chapter. The left fourth arch persists as the distal left aortic arch between the left common carotid and left subclavian arteries, and the left dorsal aorta persists to become the segment that extends between the left subclavian artery and the site of the entrance of the ductus arteriosus. The right fourth arch becomes the brachiocephalic trunk and proximal right subclavian artery, whereas the right dorsal aorta largely involutes. The proximal portions of the right and left sixth arches form the proximal right and left pulmonary arteries, respectively. The distal right sixth arch regresses, whereas the...
