Patent Arterial Duct

Some patients with pulmonary atresia with an intact ventricular septum, mild to moderate right ventricular hypoplasia, and a patent infundibulum remain duct dependent on the flow of blood through the arterial duct despite adequate relief of the obstruction within the right ventricular outflow tract.The objective of our study was to review the risk factors for stenting of the patent arterial duct, or construction of a Blalock-Taussig shunt, in the patients with pulmonary atresia and an intact ventricular septum who remain duct-dependent following radiofrequency valvotomy and dilation of the imperforate pulmonary valve.We reviewed the data from 53 patients seen between November 1995 and December 2001. Of the 47 patients who survived, 6 required stenting of the patent arterial duct, while 4 needed construction of a modified Blalock-Taussig shunt to augment the flow of blood to the lungs at a mean of 7 plus or minus 5.7 days following the initial intervention. The remaining 37 patients required no additional procedures. We compared the findings in these two groups.The mean diameter of the tricuspid valve in the patients requiring early reintervention was 8.5 plus or minus 3.7 millimetres, giving a Z-score of −1.1 plus or minus 1.47, whilst those in the group without early reintervention had values of 10.7 plus or minus 2.2 millimetres, giving a Z-score of −0.58 plus or minus 1.18 (p equal to 0.003). No statistically significant differences were found in right ventricular morphology, McGoon ratio, or residual obstruction across the right ventricular outflow tract after decompression of the right ventricle.The diameter of the tricuspid valve, therefore, appears to be the only factor predicting the need for augmentation of flow of blood to the lungs. As just over one-fifth of our survivors required such augmentation, we hypothesize that stenting of the patent arterial duct may be performed as an integral part of primary transcatheter therapy in patients with pulmonary atresia and intact ventricular septum who have moderate right ventricular hypoplasia and a small tricuspid valve.

Patent Arterial Duct

We report a case of a 750 grams premature female who was scheduled for surgical ligation of a patent arterial duct. Intra-operative findings showed a patent arterial duct in association to a retro-esophageal aortic arch creating a complete vascular ring around the trachea, which was successfully divided. A vascular ring should be ruled-out in premature infants prior to ductal ligation at bidimensional echocardiography. Keywords: congenital heart disease; premature infant; surgery; vascular ring.

Patent Arterial Duct

Hemodynamically significant patent arterial duct in premature infants can be the reason of life-threatening complications. Thus it is topical to define the high risk of such complications and mortality in early neonatal period. We have reviewed researches results covering prognostic value of natriuretic peptides level in premature infants with hemodynamically significant patent arterial duct. The data on management planning of such patients according to the A-type and B-type natriuretic peptides levels is presented.

Transcatheter techniques for occlusion of the persistently patent arterial duct using coils have become standard therapy at many centers for pediatric cardiology, and in selected patients have demonstrated comparable efficacy to surgical ligation. Surgical ligation may still be required in many cases, including premature infants or those born with low weight, those with ducts of large diameter, those with associated structural heart disease, and in circumstances of unsuccessful occlusion subsequent to attempted closure using coils. We report on the successful surgical ligation of an arterial duct of moderate size that exhibited residual patency despite two separate attempts at occlusion using coils.

(1) Background: Transcatheter closure of the patent arterial duct (TCPDA) in preterm infants is an emerging procedure. Patent arterial duct (PDA) spontaneous closure after failed TCPDA attempts is seen but reasons and outcomes are not reported; (2) Methods: We retrospectively included all premature infants <2 kg with abandoned TCPDA procedures from our institutional database between September 2017 and August 2021. Patients’ data and outcomes were reviewed; (3) Results: The procedure was aborted in 14/130 patients referred for TCPDA. Two patients had spasmed PDA upon arrival in the catheterization laboratory and had no intervention. One patient had ductal spasm after guidewire cross. Four patients had unsuitable PDA size/shape for closure. In seven patients, device closure was not possible without causing obstruction on adjacent vessels. Among the 12 patients with attempted TCPDA, five had surgery on a median of 3 days after TCPDA and seven had a spontaneous PDA closure within a median of 3 days after the procedure. Only the shape of the PDA differed between the surgical ligation group (short and conical) and spontaneous closure group (F-type); (4) Conclusions: In the case of TCPDA failure, mechanically induced spontaneous closure may occur early after the procedure. Surgical ligation should be postponed when clinically tolerated.
