Abstract Background: Patent ductus arteriosus (PDA) is highly prevalent in extremely low
birth weight (ELBW), preterm infants. There are diverse management approaches for
the PDA in ELBW infants. The objectives of this research were to identify current
PDA management practices among cardiologists and neonatologists in the United
States, describe any significant differences in management, and describe areas where
practices align.
Methods: A survey of 10 questions based on the management of PDA in ELBW infants was conducted among 100 prominent neonatologists from 74 centers and 103
prominent cardiologists from 75 centers. Among the cardiologists, approximately
50% were interventionists who perform transcatheter… More >

Abstract Regulation of the ductus arteriosus, an essential fetal vessel connecting the pulmo‐
nary artery and aorta, is complex. Failure of this vessel to close after birth may result
in a persistent left‐to‐right shunt through the patent ductus arteriosus, a condition
associated with significant morbidities. Numerous factors contribute to the shift from
fetal ductus patency to postnatal closure, requiring precise coordination of molecular
cues with biomechanical forces and underlying genetic influences. Despite significant
advances, questions remain regarding signaling dynamics and the natural time course
of ductus closure, particularly in preterm neonates. This review highlights the contri‐
butions of early investigators and… More >

Abstract Objective: There is no consensus on the definition of a hemodynamically significant
patent ductus arteriosus (hsPDA). In this review article, our objective is to discuss the
main variables that one should consider when determining the hemodynamic signifi‐
cance of a PDA.
Results: We describe the various approaches that have been utilized over time to
define an hsPDA and discuss the strengths and weaknesses of each echocardio‐
graphic index. Finally, we propose a comprehensive and individualized approach in
determining the hemodynamic significance of the PDA.
Conclusion: There are several PDA‐related clinical, echocardiographic, and other ob‐
jective variables to take into consideration… More >

Abstract Patent ductus arteriosus (PDA) is prevalent in premature newborns and has been
linked to the development of bronchopulmonary dysplasia (BPD), a serious pulmonary complication of premature birth. Although a causal relationship has not been
proven, the link is greatest among infants born at lower gestational age who are
treated with mechanical ventilation in the presence of a large ductal shunt. Despite
strong association in epidemiological studies, treatment of a patent ductus arteriosus
has not been shown to prevent BPD, and some therapies may increase the risk of
BPD. We describe preclinical and clinical data demonstrating the association of a
PDA… More >

Abstract Management of the patent ductus arteriosus (PDA) in the premature infant has been
a point of controversy for decades as smaller and earlier gestational age infants have
been surviving. Increasing experience with catheter‐based device closure has gener‐
ated a new wave of interest in this subject. In this era, echocardiography plays a cen‐
tral role for collaboration within a multispecialty team. Reliability of echocardiography
is improved by applying an institutionally derived standard approach to imaging, data
collection, and reporting. The key aspects of both the physiology and anatomy of the
PDA to distinguish infants that may benefit from intervention are… More >

Abstract Management of patent ductus arteriosus in extremely preterm infants remains a
topic of debate. Treatment to produce ductal closure was widely practiced until the
past decade, despite lack of evidence that it decreases morbidities or mortality.
Meta‐analyses of trials using nonsteroidal anti‐inflammatory drugs have shown ef‐
fectiveness in accelerating ductal closure, but no reduction in neonatal morbidities,
regardless of agent used, indication, timing, gestational age, or route of administra‐
tion. Surgical ligation closes the ductus but is associated with adverse effects.
Recent experience with conservative approaches to treatment suggest improved
neonatal outcomes and a high rate of spontaneous ductal closure… More >

Abstract Even though up to 60% of premature infants less than 28 weeks gestation develop
persistent patent ductus arteriosus (PDA), there remains controversy regarding if,
when, and how to close the PDA. Failure to close the PDA has been associated with
significant morbidity but no cause‐and‐effect has been proven for short‐term or
long‐term outcomes in modern times. Surgical closure has the advantage of eliminating the PDA, but short‐term complications and long‐term adverse outcomes are worrisome. Intravenous indomethacin has been the “gold standard” for pharmacologic
treatment over the past 40 years with high closure rates and decreased incidence of
severe intraventricular hemorrhage… More >

Abstract Surgical ligation of patent ductus arteriosus can be performed safely by following
standard steps of operation. Familiarity of the anatomical landmarks and simple pre‐
cautions result in high degree of safety. The technique of surgical ligation varies with
the age of the patient. Surgical ligation of ductus is associated with well‐recognized
complications, although they occur only in a small number of patients. More >

Abstract Clinically significant patent ductus arteriosus (PDA) has been associated with signifi‐
cant morbidity in extremely low birth weight (ELBW) infants. Current management of
ELBW infants with hemodynamically significant PDA includes supportive treatment,
pharmacological therapy, and surgical ligation. All of these therapeutic options have
their advantages and limitations. More recently, transcatheter PDA closure has been
described as a viable option in this population. In this paper, we provide a compre‐
hensive review of this emerging procedure. More >

Abstract The ductus arteriosus is a lifeline for the developing fetus prior to delivery, allowing
the circulation of oxygen‐rich blood from the placenta to bypass the lungs and per‐
fuse the body. However, when the ductus fails to close after birth, the pressures can
cause blood to shunt from the aorta back into the lungs, causing pulmonary edema.
This is called a left‐to‐right shunt. The patent ductus arteriosus (PDA) can also shunt
blood from the pulmonary arteries to the aorta, bypassing the lungs and causing oxy‐
gen‐poor blood to mix with the oxygen‐rich blood circulating to the body. This is
called… More >

Abstract The optimal treatment method for infants with a patent ductus arteriosus (PDA) necessitating closure remains a subject of controversy and debate. While the risks associated with surgical PDA ligation are well described, the available evidence base for
alternative management strategies during infancy, including percutaneous closure or
conservative (nonintervention) management, are not well explored. Among infants,
the goals of this review are to: (a) use rigorous systematic review methodology to assess the quality and quantity of published reports on percutaneous closure vs surgical ligation; (b) compare outcomes of percutaneous closure vs conservative
management; and (c) based on recommendations from the International… More >

Abstract The ductus arteriosus (DA) has been studied since Galen. Initially after birth in neo‐
nates with obstruction to pulmonary blood flow, DA patency is integral to ensure out‐
put and oxygenation. While DA stenting dates back 25 years, there is emerging interest
in better understanding how and when to utilize this strategy as an alternative to surgi‐
cal shunt placement or ongoing prostaglandin administration. Understanding the nor‐
mal fetal circulation and the perturbations that affect flow and oxygenation is integral
to comprehending how normal DA anatomy and morphology may change and how this
may influence technical and clinical considerations. In… More >

Abstract Background: Infants with ductal-dependent pulmonary blood flow (PBF) often undergo a palliative procedure to provide a stable source of PBF prior to definitive palliation or repair. In the current era, a surgical shunt or ductal stent is used to provide
PBF. We aimed to review the current literature comparing ductal stents to surgical
shunts.
Methods and Results: Four small, single-center studies and two larger multicenter
studies were identified comparing ductal stent to surgical shunt. Combined, these
studies showed ductal stent resulted in similar or improved pulmonary artery growth,
fewer complications, shorter length of stay, less diuretic use, and improved survival… More >

Abstract The use of prostaglandin‐E1 immediately after birth and subsequent surgical crea‐
tion of the modified Blalock‐Taussig shunt (BTS) shunt have remarkably improved the
prognosis and survival of children with congenital heart disease and ductal‐depend‐
ent pulmonary blood flow (PBF). Despite the advancement in surgical techniques,
bypass strategies, and postoperative management, significant morbidity and mortal‐
ity after BTS still remain. Patent ductus arteriosus stenting has been shown to be as
an acceptable alternative to BTS placement in select infants with ductal‐dependent
PBF. Newer procedural techniques and equipment, along with operator experience
have all contributed to procedural refinement associated with improved outcomes… More >
