Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.

Prenatal features of ductus arteriosus constriction and restrictive foramen ovale in d-transposition of the great arteries. (1/253)

BACKGROUND: Although most neonates with d-transposition of the great arteries (TGA) have an uncomplicated preoperative course, some with a restrictive foramen ovale (FO), ductus arteriosus (DA) constriction, or pulmonary hypertension may be severely hypoxemic and even die shortly after birth. Our goal was to determine whether prenatal echocardiography can identify these high-risk fetuses with TGA. METHODS AND RESULTS: We reviewed the prenatal and postnatal echocardiograms and outcomes of 16 fetuses with TGA/intact ventricular septum or small ventricular septal defect. Of the 16 fetuses, 6 prenatally had an abnormal FO (fixed position, flat, and/or redundant septum primum). Five of the 6 had restrictive FO at birth. Five fetuses had DA narrowing at the pulmonary artery end in utero, and 6 had a small DA (diameter z score of <-2.0). Of 4 fetuses with the most diminutive DA, 2 also had an abnormal appearance of the FO, and both died immediately after birth. One other fetus had persistent pulmonary hypertension. Eight fetuses had abnormal Doppler flow pattern in the DA (continuous high-velocity flow, n=1; retrograde diastolic flow, n=7). CONCLUSIONS: Abnormal features of the FO, DA, or both are present in fetuses with TGA at high risk for postnatal hypoxemia. These features may result from the abnormal intrauterine hemodynamics in TGA. A combination of restrictive FO and DA constriction in TGA may be associated with early neonatal death.  (+info)

Inducible NO synthase inhibition attenuates shear stress-induced pulmonary vasodilation in the ovine fetus. (2/253)

Recent studies have suggested that type II (inducible) nitric oxide (NO) synthase (NOS II) is present in the fetal lung, but its physiological roles are uncertain. Whether NOS II activity contributes to the NO-mediated fall in pulmonary vascular resistance (PVR) during shear stress-induced pulmonary vasodilation is unknown. We studied the hemodynamic effects of two selective NOS II antagonists [aminoguanidine (AG) and S-ethylisothiourea (EIT)], a nonselective NOS antagonist [nitro-L-arginine (L-NNA)], and a nonselective vasoconstrictor (U-46619) on PVR during partial compression of the ductus arteriosus (DA) in 20 chronically prepared fetal lambs (mean age 132 +/- 2 days, term 147 days). At surgery, catheters were placed in the left pulmonary artery (LPA) for selective drug infusion, an ultrasonic flow transducer was placed on the LPA to measure blood flow, and an inflatable vascular occluder was placed loosely around the DA for compression. On alternate days, a brief intrapulmonary infusion of normal saline (control), AG, EIT, L-NNA, or U-46619 was infused in random order into the LPA. The DA was compressed to increase mean pulmonary arterial pressure (MPAP) 12-15 mmHg above baseline values and held constant for 30 min. In control studies, DA compression reduced PVR by 42% from baseline values (P < 0.01). L-NNA treatment completely blocked the fall in PVR during DA compression. AG and EIT attenuated the decrease in PVR by 30 and 19%, respectively (P < 0.05). Nonspecific elevation in PVR by U-46619 did not affect the fall in PVR during DA compression. Immunostaining for NOS II identified this isoform in airway epithelium and vascular smooth muscle in the late-gestation ovine fetal lung. We conclude that selective NOS II antagonists attenuate but do not block shear stress-induced vasodilation in the fetal lung. We speculate that stimulation of NOS II activity, perhaps from smooth muscle cells, contributes in part to the NO-mediated fall in PVR during shear stress-induced pulmonary vasodilation.  (+info)

Cyclooxygenase-2 plays a significant role in regulating the tone of the fetal lamb ductus arteriosus. (3/253)

Nonselective cyclooxygenase (COX) inhibitors are potent tocolytic agents but have adverse effects on the fetal ductus arteriosus. We hypothesized that COX-2 inhibitors may not affect the ductus if the predominant COX isoform is COX-1. To examine this hypothesis, we used ductus arteriosus obtained from late-gestation fetal lambs. In contrast to our hypothesis, fetal lamb ductus arteriosus expressed both COX-1- and COX-2-immunoreactive protein (by Western analysis). Although COX-1 was found in both endothelial and smooth muscle cells, COX-2 was found only in the endothelial cells lining the ductus lumen (by immunohistochemistry). The relative contribution of COX-1 and COX-2 to PGE2 synthesis was consistent with the immunohistochemical results: in the intact ductus, PGE2 formation was catalyzed by both COX-1 and COX-2 in equivalent proportions; in the endothelium-denuded ductus, COX-2 no longer played a significant role in PGE2 synthesis. NS-398, a selective inhibitor of COX-2, was 66% as effective as the selective COX-1 inhibitor valeryl salicylate and the nonselective COX inhibitor indomethacin in causing contraction of the ductus in vitro. At this time, caution should be used when recommending COX-2 inhibitors for use in pregnant women.  (+info)

The effects of maternal indomethacin therapy on human fetal branch pulmonary arterial vascular impedance. (4/253)

OBJECTIVE: To examine whether maternal indomethacin therapy affects human fetal pulmonary arterial vascular impedance without constriction of the ductus arteriosus and to determine the changes in the pulmonary arterial vascular impedance in the presence of ductal constriction. STUDY DESIGN: In this cross-sectional study, 52 normal fetuses without maternal medication (control group), 33 fetuses without ductal constriction (Study group I) and 11 fetuses with ductal constriction (Study group II) during maternal indomethacin therapy between 24 and 34 weeks of gestation were examined by Doppler echo-cardiography. Blood velocity waveforms across the proximal right or left pulmonary artery were obtained and the pulsatility index (PI) of the proximal pulmonary arteries was calculated. RESULTS: In the control group, the proximal pulmonary artery PI was higher (p < 0.0001) at 24-25 weeks (n = 7) (3.73 +/- 0.33; mean +/- SD) than at 33-34 week of gestation (n = 11) (2.98 +/- 0.27). The PI was constantly greater (p < 0.005) in Study group I than in the control group. However, in this group the mean average weekly decrease in the PI of the proximal pulmonary arteries was similar to that in the control group. After 26 weeks of gestation, the PI values in Study group II were significantly higher than in the control group (27 weeks: 4.12 vs. 3.34 (p < 0.005); 30 weeks: 4.48 vs. 3.14 (p < 0.0001); 34 weeks: 4.96 vs. 3.00 (p < 0.0001), respectively). CONCLUSIONS: Human fetal pulmonary arterial vascular impedance is increased by maternal indomethacin therapy even without ductal constriction. In the presence of ductal constriction, the magnitude of the increase in the vascular impedance is related to the gestational age.  (+info)

Biventricular repair approach in ducto-dependent neonates with hypoplastic but morphologically normal left ventricle. (5/253)

OBJECTIVES: Increased afterload and multilevel LV obstruction is constant. We assumed that restoration of normal loading conditions by relief of LV obstructions promotes its growth, provided that part of the cardiac output was preoperatively supported by the LV, whatever the echocardiographic indexes. BACKGROUND: Whether to perform uni- or biventricular repair in ducto dependent neonates with hypoplastic but morphologically normal LV (hypoplastic left heart syndrome classes II & III) remains unanswered. Echocardiographic criteria have been proposed for surgical decision. METHODS: Twenty ducto dependent neonates presented with this anomaly. All had aortic coarctation associated to multilevel LV obstruction. Preoperative echocardiographic assessment showed: mean EDLW of 12.4 +/- 3.03 ml/m2 and mean Rhodes score of -1.73 +/-0.8. Surgery consisted in relief of LV outflow tract obstruction by coarctation repair in all associated to aortic commissurotomy in one and ASD closure in 2. RESULTS: There were 3 early and 2 late deaths. Failure of biventricular repair and LV growth was obvious in patients with severe anatomic mitral stenosis. The other demonstrated growth of the left heart. At hospital discharge the EDLVV was 19.4+/-3.12 ml/m2 (p = 0.0001) and the Rhodes score was -0.38+/-1.01 (p = 0.0003). Actuarial survival and freedom from reoperation rates at 5 years were 72.5% and 46%, respectively. CONCLUSIONS: Biventricular repair can be proposed to ducto dependent neonates with hypoplastic but morphologically normal LV provided that all anatomical causes of LV obstruction can be relieved. Secondary growth of the left heart then occurs; however, the reoperation rate is high.  (+info)

Coanda effect on ductal flow in the pulmonary artery. (6/253)

The Coanda effect (the tendency of a jet stream to adhere to a boundary wall), and the relevant anatomy, may explain the location of ductal jets within the main pulmonary artery. With the usual insertion of the duct close to the left pulmonary artery, during right ventricular ejection, the ductal jet adheres to the left wall of the main pulmonary artery. When right ventricular ejection is absent in pulmonary atresia, the ductal jet streams down the right wall of the pulmonary artery to the pulmonary valve, reverses, and maintains a parallel column back toward the bifurcation. If the reversed flow is mistaken for ejection from the right ventricle, the diagnosis of pulmonary atresia may be missed.  (+info)

Fate of the stented arterial duct. (7/253)

BACKGROUND: The technical aspects of ductal stenting have been reported, but little is known of the fate of the duct after stent implantation. METHODS AND RESULTS: Nineteen patients underwent stent implantation to maintain ductal patency. Eight had hypoplastic left heart (HLH) syndrome, 10 had pulmonary atresia, and 1 had tricuspid atresia. Median survival with HLH was 57 (12 to 907) days. Stent implantation was successful in all cases of HLH, but there were no long-term survivors. Two well-palliated infants died at transplantation. Median survival with duct-dependent pulmonary flow was 183 (0 to 1687) days, with 3 patients well at latest follow-up (56, 55, and 9 months, respectively). There were 2 operative deaths due to ductal spasm and 4 late deaths, 1 due to duct thrombosis, 1 due to chronic lung disease, and 2 of unknown cause. Stent implantation failed in 4 of the 11 cases. Assessment of endothelialization was possible in 13 cases; the stent was partially covered in 3 and fully endothelialized in all 10 cases assessed >8 weeks after implantation. In patients stented for inadequate pulmonary flow, ductal intimal hyperplasia occurred by 9 months in all 3 survivors but responded to repeated dilation. CONCLUSIONS: Ductal stenting cannot be recommended. In patients with HLH, it provides only short-term palliation even when combined with pulmonary artery banding. With duct-dependent pulmonary blood flow, the procedure carries high risk, and duration of palliation is poor. In patients with bilateral ducts and absent central pulmonary arteries, good palliation may be achieved, but repeated angioplasty is necessary to counteract intimal hyperplasia.  (+info)

Ductus venosus blood velocity in persistent pulmonary hypertension of the newborn. (8/253)

AIMS: To investigate the ductus venosus flow velocity (DVFV) in infants with persistent pulmonary hypertension of the newborn (PPHN); to evaluate the DVFV pattern as a possible diagnostic supplement in neonates with PPHN and other conditions with increased right atrial pressure. METHODS: DVFV was studied in 16 neonates with PPHN on days 1-4 of postnatal life using Doppler echocardiography. DVFV was compared with that in mechanically ventilated neonates with increased intrathoracic pressure, but without signs of PPHN (n=11); with neonates with congenital heart defects resulting in right atrial pressure (n=6); and with preterm neonates without PPHN (n=46); and healthy term neonates (n=50). RESULTS: Infants with PPHN and congenital heart defects with increased right atrial pressure were regularly associated with an increased pulsatile pattern and a reversed flow velocity in ductus venosus during atrial contraction. A few short instances of reversed velocity were also noted in normal neonates before the circulation had settled during the first day after birth. CONCLUSIONS: A reversed velocity in the ductus venosus during atrial contraction at this time signifies that central venous pressure exceeds portal pressure. This negative velocity deflection is easily recognised during Doppler examination and can be recommended for diagnosing increased right atrial pressure and PPHN.  (+info)

Ca2+ influx through voltage-dependent Ca2+ channels regulates vascular remodeling and contraction. However, the role of T-type Ca2+ channels (TCCs) has remained unknown in the ductus arteriosus (DA). Here we hypothesized that Ca2+ influx via TCC contributed to DA closure through promoting neointimal cushion formation and oxygen-induced vascular contraction. Quantitative RT-PCR analysis revealed that α1G, a TCC subtype, was significantly up-regulated in rat neonatal DA tissues at birth and in DA smooth muscle cells (SMCs) that were exposed to oxygen. The expression of α1G mRNA was higher in DA than in the aorta. Immunohistlogical analysis revealed that α1G was localized predominantly to the region of intimal thickening in fetal DA at term and to the central core of neonatal DA at birth. To examine the effects of blockade of TCCs, we used α1G-specific siRNA or R(−)-efonidipine, a highly selective TCC blocker that was recently developed. α1G-specific siRNAs inhibited SMC migration by 55% ...

We have previously demonstrated that this potent vasoconstricting response is due, in part, to an endothelin-1 (ET-1)-mediated decrease in nitric oxide synthase (NOS) activity. In addition, in vitro data demonstrate that ET-1 increases superoxide levels in pulmonary arterial smooth muscle cells and that oxidative stress alters NOS activity. Therefore, the objectives of this study were to ...

You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack. Use of NSAIDs, including Naproxen Suspension, during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Adverse reactions reported in controlled clinical trials in patients treated for rheumatoid arthritis or osteoarthritis are listed below. There is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus and intracranial hemorrhage. This should be considered in patients whose overall intake of sodium must be severely restricted. All rights reserved.. ...
In this lesson, we learn about the 3 shunts of fetal circulation: ductus arteriosus, ductus venosus, and foramen ovale of the fetal heart: functions, medical significance, when they close, medical complications, and remnant ligaments.
The Ductus arteriosus (DA) of the unborn child constitutes a vascular connection between the aorta and the pulmonary trunk during fetal life. It allows the blood to bypass the pulmonary circulation. Prenatal structural changes of the DA begin in preparation of its postnatal closure and obliteration. Physiologically, DA closure occurs within the first 72 hours of life. In preterm newborns, immaturity of the closure mechanisms can lead to a persisting ductus arteriosus (PDA) beyond this point of life. In this case, an attempt at closing a hemodynamically significant PDA (hsPDA) can be made by treating the preterm with COX (Cyclooxygensase)-inhibitors, such as ibuprofen or indomethacin. Today, surgical PDA ligation is a rescue therapy for those infants in whom COX-inhibitor treatment failed to close the duct. Polymorphisms in the CYP2C8-enzyme can lead to altered metabolizing patterns of drugs metabolized by the cytochrome P450 system, e.g. COX-inhibitors. The goal of this study was to find out, if ...

Risk Summary Use of NSAIDs, including INDOCIN, during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs, including INDOCIN, in pregnant women starting at 30 weeks of gestation (third trimester). There are no adequate and well-controlled studies of INDOCIN in pregnant women. Data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In the general U.S. population, all clinically recognized pregnancies, regardless of drug exposure, have a background rate of 2-4% for major malformations, and 15-20% for pregnancy loss. In animal reproduction studies retarded fetal ossification was observed with administration of indomethacin to mice and rats during organogenesis at doses 0.1 and 0.2 times, respectively, the maximum recommended human dose (MRHD, 200 mg (40 mL)). In published studies in pregnant mice, indomethacin produced maternal ...

A widened pulse pressure could be a sign of a patent ductus arteriosus in an infant. This is defined as a difference between systolic and diastolic blood pressure of greater than 15 to 25 mmHg, in premature infants and greater than 25 mmHg in term infants [1]. It is thought that diastolic runoff from blood flow shunting across the aorta to the pulmonary artery, through the patent ductus arteriosus, will produce a lower diastolic pressure and therefore widen the pulse pressure in the affected infant [1]. In our retrospective chart review, 116 premature infants were identified with a patent ductus arteriosus and compared to 42 premature infants without a patent ductus arteriosus. The blood pressures obtained were recorded for the first 7 days of life of the patients. Our studies revealed that premature infants with a patent ductus arteriosus had a mean pulse pressure of19 mmHg (p-value 0.129) when compared to infants without a patent ductus arteriosus,16 mmHg, on day 1 of life. The mean pulse pressures

|p|Patent ductus arteriosus (PDA) is the most prevalent cardiovascular defect and is more often seen in females; premature babies are at increased risk. For both sexes, a relationship exists between the risk of this defect occurring and the higher dimensions of the ductus arteriosus. In this study, we examined the relationship between the dimensions of the ductus arteriosus (diameter, length, capacity) and sex. We analyzed a total of 223 fetuses, 108 males and 115 females, ranging in age from four to eight months of intrauterinal life. All fetuses of normal karyotype were obtained from spontaneous abortions. None of the analyzed specimens demonstrated any visible malformations. The increase in the length and diameters of the ductus is linearly related to gestational age. The volumetric growth of this vessel was dependent on fetal age, according to the exponential function. The large number of analyzed specimens allows reliable determination of the ductus arteriosus dimensions in

OBJECTIVE: To report initial experience with a new occlusion device for native and residual patent ductus arteriosus. DESIGN: Descriptive study of consecutive non-randomised patients undergoing a new method of patent ductus arteriosus closure with detachable coils. SETTING: Tertiary centres for paediatric cardiology. PATIENTS: 71 consecutive patients, aged 1.2-22 years, with a patent ductus arteriosus (PDA) underwent elective transcatheter closure. 45 had native PDAs (group A) with a minimum diameter of 1.0 mm-5.0 mm (median 2.0 mm). A further 26 had undergone one or more previous occlusion attempts (group B). INTERVENTIONS: A total of 133 detachable (Cook) spring coils were successfully implanted in 70 patients. The procedure was performed transvenously in 51 patients, retrograde arterially in 13, and by both routes in a further 6 patients. One 5 mm coil migrated but was successfully retrieved.

Patent ductus arteriosus is one of the most common congenital heart diseases in the dog. During fetal growth, the ductus arteriosus allows blood to flow from the pulmonary artery into the aorta so that the not-functioning lungs are bypassed. The two main factors that keep the ductus open are ... read more the low oxygen tension in the blood and the high levels of prostaglandin E2 from the placenta. Within minutes to hours after birth, the vessel constricts and closes due to a rise in oxygen tension and the deterioration of placental PGE2. In case of PDA, the ductus arteriosus fails to close after birth. In dogs with PDA, a very typical continuous murmur can be heard on the left heart base. Untreated, PDA will cause death within the first year in one third of all cases. Histopathological, asymmetry and hypoplasia of the ductus muscle is seen. Also, parts of the ductus muscle contain non-contracting aorta like elastic structure. Several dog breeds are predisposed, indicating that there is a ...
Objective: To study whether indomethacin used in conventional dose for closure of patent ductus arteriosus affects cerebral function measured by Electroencephalograms (EEG) evaluated by quantitative measures.

Patent ductus arteriosus (PDA) is a condition wherein the ductus arteriosus fails to close after birth. Early symptoms are uncommon, but in the first year of life include increased work of breathing and poor weight gain. An uncorrected PDA may lead to congestive heart failure with increasing age. The ductus arteriosus is a fetal blood vessel that closes soon after birth. In a PDA, the vessel does not close and remains patent (open), resulting in irregular transmission of blood between the aorta and the pulmonary artery. PDA is common in newborns with persistent respiratory problems such as hypoxia, and has a high occurrence in premature newborns. Premature newborns are more likely to be hypoxic and have PDA due to underdevelopment of the heart and lungs. A PDA allows a portion of the oxygenated blood from the left heart to flow back to the lungs by flowing from the aorta (which has higher pressure) to the pulmonary artery. If this shunt is substantial, the neonate becomes short of breath: ...
The ductus arteriosus is a blood vessel that connects the pulmonary artery and the aorta. In the fetus, it enables blood to bypass the lungs. The fetus does not breathe air, and thus blood does not need to pass through the lungs to be oxygenated. After birth, blood does need to be oxygenated in the lungs, and normally the ductus arteriosus closes quickly, usually within days up to 2 weeks. In patent ductus arteriosus, this connection does not close, allowing some oxygenated blood, intended for the body, to return to the lungs. As a result, the blood vessels in the lungs may be overloaded and the body may not receive enough oxygenated blood.. ...
Patent ductus arteriosus is a medical condition where a blood vessel called the ductus arteriosus does not permanently close after birth. Learn why the ductus arteriosus does not close, why patients with this condition have a wide pulse pressure, and how the disease is treated with surgery and nonsteroidal anti-inflammatory drugs (NSAIDs).

Patent ductus arteriosus, or PDA, is a malformation of the heart caused by failure of normal closure of the ductus arteriosus, a direct connection between the aorta and the pulmonary artery which is present and functional during fetal life but which is unnecessary once air-breathing begins. Normally the ductus closes shortly after birth; this process of closure by muscular contraction is reversible for a short time - it can be reopened under hormonal control (prostaglandins). However, within a few weeks it is permanently closed. If the ductus fails to close normally, a loud to-and-fro murmur will result (the so-called machinery murmur). Very young patients with heart or lung disease may need to have the ductus repaired to prevent too much blood from flowing back from the high pressure side of the circulation - the aorta. This lesion also places an older patient at some risk of bacterial endocarditis, so ordinarily the patent ductus is surgically tied off. ...
The patency of the ductus arteriosus is very common in extremely premature infants. The increased pulmonary blood flow that results from left-to-right ductal shunting can produce an acute deterioration in lung function and some data suggest that it may increase the risk of chronic lung damage. However, there is no clear evidence that prophylactic or early closure of the patent ductus arteriosus (PDA) results in a clear reduction in bronchopulmonary dysplasia. For this reason, and because of the side effects of the available therapies to close the ductus, there is a wide variation in the approach to the PDA in this population and most clinicians will intervene to close the ductus only in cases of significant shunt with hemodynamic decompensation ...

AU - Thomas, Rachel E.. AU - Leegwater, Peter A.J.. AU - Heuven, Henri C.M.. PY - 2016/6/13. Y1 - 2016/6/13. N2 - Background: Patent ductus arteriosus (PDA) is one of the most common congenital heart defects in dogs and is considered to be a complex, polygenic threshold trait for which a female sex predisposition has been described. Histological studies in dogs suggest that smooth muscle hypoplasia and asymmetry of the ductus tissue is the major cause of PDA. The Stabyhoun population is small and a predisposition for PDA has been suggested. The aims of this study were to describe the incidence, presentation from a clinical and histopathological perspective, and the population genetics of PDA in the Dutch Stabyhoun population. Results: Forty-six cases were identified between 2000 and 2013. Between 2009 and 2012 the ...
The authors report the case of a 14 month old girl with patent ductus arteriosus born from the first, uncomplicated and regulary controlled pregnancy. At 13 months of age a continuous murmur was diagnosed. Doppler echocardiography confirmed patent ductus Botalli and she underwent an operation (because of her age) at the Pediatric Hospital G. Pasquinucci in Massa e Carrara, Italy. During aortography, closure of the ductus arteriosus with large and short infundibulum (dimension 2,0 mm in diameter) was performed with a Gianturco coil (size 5 mm). Procedure was well tolerated and successful. Control Doppler echocardiography revealed normal flow without a shunt ...

However, the aortic pressure and systemic arterial
The histology of the ductus arteriosus was studied after prostaglandin E1 (PGE1) administration in 4 infants with ductus dependent cardiac malformations. Pronounced pathological changes were found in each instance. The changes consisted of oedema of the media with separation of medial components by clear spaces, pathological interruptions of the internal elastic lamina, and intimal lacerations, some of which extended into the media. The findings suggest that PGE1 administration has a profound weakening effect on the structure of the wall of the ductus arteriosus, rendering the vessel prone to laceration. ...

Hey Stef.. me again.. ok.. this is what Ive found out.. If your friend does get pregnant while on this med, she needs to tell her doc as soon as possible.. the reason why is cause in late pregnancy, as with other NSAIDs, Piroxicam or FELDENE should be avoided because it may cause premature closure of the ductus arteriosus.. Ductus arteriosus is a key arterial shunt (ductus) in fetal life. Before birth, blood pumped from the heart through the pulmonary artery toward the lungs is shunted into the aorta. This arterial shunt is a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent. The ductus arteriosus usually closes at or shortly after birth, permitting blood from that moment on to course from the heart directly to the lungs. However, if the ductus arteriosus remains open (patent), flow reverses and blood from the aorta is shunted left-to-right into the pulmonary artery and thence recirculated through the lungs. A PDA may close spontaneously (on its own). ...
