Peri-operative changes in echocardiographic measurements and plasma atrial and brain natriuretic peptide concentrations in 3 dogs with patent ductus arteriosus. (1/531)

Peri-operative changes in echocardiographic measurements and plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) were investigated for 1 month in 3 dogs with patent ductus arteriosus (PDA). Post-operative left ventricular end-diastolic dimention and fractional shortening decreased in all cases. Pre-operatively increased plasma ANP concentrations reduced dramatically after the operation. Peri-operative changes in plasma BNP levels had slightly S-shaped curves in all cases. These observations suggest that post-operative responsiveness of ANP and cardiac function are rapid in comparison with cardiac morphological changes, and BNP has a different pathophysiological significance from ANP in dogs with PDA.  (+info)

Follow-up results of transvenous occlusion of patent ductus arteriosus with the buttoned device. (2/531)

OBJECTIVES: The purpose of this presentation is to document results of buttoned device (BD) occlusion of patent ductus arteriosus (PDA) in a large number of patients with particular emphasis on long-term follow-up in an attempt to provide evidence for feasibility, safety and effectiveness of this method of PDA closure. BACKGROUND: Immediate and short-term results of BD occlusion of PDA have been documented in a limited number of children. METHODS: During a six-year period ending August 1996, transcatheter BD closure of PDA was attempted in 284 patients, ages 0.3 to 92 years (median 7) under a protocol approved by the local institutional review boards and FDA with an investigational device exemption in U.S. cases. RESULTS: The PDAs measured 1 to 15 mm (median 4) at the narrowest diameter; 20 were larger than 8 mm and 10 larger than 10 mm. They were occluded with devices measuring from 15 to 35 mm delivered via 7F (N = 140) or 8F (N = 144) sheaths. Successful implantation of the device was accomplished in 278 (98%) of 284 patients. The Qp:Qs decreased from 1.8+/-0.6 (mean+/-SD) to 1.09+/-0.19 (p < 0.001). Effective occlusion defined as no (N = 167 [60%]) or trivial (N = 79 [28%]) residual shunt was achieved in 246 (88%) patients. All types of PDAs, irrespective of the shape (conical, tubular or short), size (small or large) or length (short or long) of the PDA and previously implanted Rashkind devices, could be occluded. Follow-up data, 1 to 60 months (median 24) after device implantation, were available in 234 (84%) patients. Seven (3%) patients required reintervention to treat residual shunt with (N = 2) or without (N = 5) hemolysis. Actuarial reintervention-free rates were 95% at 1 and 5 years. There was gradual reduction of actuarial residual shunts and were 40%, 28%, 21%, 14%, 11%, 10%, 6% and 0% respectively at 1 day, 1, 6, 12, 24, 36, 48 and 60 months after device implantation. Incorporation of folding plug over the button loop in 10 additional patients produced immediate and complete occlusion of PDA. CONCLUSIONS: This large multiinstitutional experience confirms the feasibility, safety and effectiveness of buttoned device closure of PDAs. All types of PDAs irrespective of the shape, length and diameter can be effectively occluded. Incorporation of folding plug over the button loop produces complete PDA occlusion at the time of device implantation.  (+info)

Cardiac function and morphology studied by two-dimensional Doppler echocardiography in unsedated newborn pigs. (3/531)

The newborn pig is currently the most used species in animal neonatal research. Valid non-invasive monitoring is important in particular for long-term survival of unsedated animals. In the unsedated newborn pig (n = 35, median age 24 h, range 7-48 h) we standardized two-dimensional Doppler echocardiography and determined the normal ranges for cardiac function. Probe positioning had to be adjusted to the V-shaped thorax and the mid-line position of the heart. Six out of the sixteen animals < 20 h had a patent ductus arteriosus compared with one of the twenty animals > 20 h old. One atrial septal defect (5 mm) and one small ventricular septal defect were diagnosed. The average heart size was 0.7-0.9% of body weight which is similar to human infants of the same size. The mean aortic diameter was 6.0 +/- 0.5 mm (mean +/- S.D.) and cardiac output was 0.38 +/- 0.08 l min-1; both correlate with body weight (r = 0.80 and 0.73, respectively). Tricuspid regurgitation velocity was 3.0 +/- 0.4 m s-1 (mean +/- S.D.), giving an estimated pressure gradient across the tricuspid valve of 37 +/- 9.7 mmHg. The aortic diameter and the heart weight per kg body weight are comparable to those reported for preterm neonates. The cardiac output and velocities across the four valves are more comparable with term neonates.  (+info)

Haemodynamic effects of altering arterial oxygen saturation in preterm infants with respiratory failure. (4/531)

AIMS: To examine the haemodynamic effects of brief alteration in arterial oxygenation in preterm infants with respiratory failure. METHODS: Eighteen preterm infants with respiratory failure, aged 9-76 hours, underwent detailed Doppler echocardiographic assessment at 86%, 96%, and 100% SaO2, achieved by altering the FIO2. Sixteen were receiving intermittent positive pressure ventilation, median FIO2 0.45 (0.20-0.65), median mean airway pressure 12 cm H2O (0-20). SaO2 was stable for 15 minutes at each stage. Four parameters of pulmonary arterial pressure were measured: peak velocity of tricuspid regurgitation and peak velocity of left to right ductal flow, TPV:RVET ratio and PEP:RVET ratio, measured at the pulmonary valve, along with flow velocity integrals at the aortic and pulmonary valves, and systemic arterial pressure. Ductal size was graded into closed, small, moderate, large with imaging, pulsed and continuous wave Doppler. RESULTS: Between 86% and 96% SaO2, there were no consistent changes, but in three of the 12 with a patent ductus arteriosus (PDA) there was ductal constriction, with complete closure in one. Between 96% and 100% SaO2, peak ductal flow velocity rose significantly in four of eight with a PDA. Ductal constriction occurred in four infants; in three this was associated with a significant fall in aortic flow integral and a rise in aortic pressure (4-6 mm Hg). Overall, 11 infants went from 86% to 100% SaO2 and pulmonary arterial pressure fell significantly in seven. CONCLUSION: A brief rise in SaO2 within the range maintained by most neonatal units can cause significant ductal constriction. The fall in pulmonary arterial pressure with 100% SaO2 seen in most infants was associated with a fall in pulmonary blood flow (or no change), rather than a rise, indicating that the dominant haemodynamic effect was ductal constriction rather than pulmonary vasodilation.  (+info)

Prostacyclin concentrations and transitional circulation in preterm infants requiring mechanical ventilation. (5/531)

AIM: To describe the association between early postnatal prostacyclin concentrations in preterm infants; echocardiographic measurements of ductal diameter and ventricular output and clinical outcomes of intraventricular haemorrhage (IVH) and patent ductus arteriosus (PDA). METHODS: Forty nine preterm infants born before 30 weeks of gestational age (median birthweight 980 g, median gestational age 27 weeks) underwent echocardiographic studies at 5, 12, 24 and 48 hours of postnatal age. Measurements included ventricular outputs and the ductal shunt diameter as a measure of the shunt size. Simultaneous measurements of blood pressures, mean airway pressure and inspired fraction of oxygen (FIO2) were recorded. A blood sample for the prostacyclin metabolite 6-ketoprostaglandin F1-alpha (6KPGF1 alpha) was taken at the 5 and 24 hour echocardiogram. RESULTS: The mean 6KPGF1 alpha concentrations were higher than adult concentrations at 5 (515 pg/ml) and 24 (255 pg/ml) hours. There was no association with gestational age. Raised 6KPGF1 alpha concentrations were related to increased need for mechanical ventilation and severity of respiratory disease. At 5 hours, increased 6KPGF1 alpha concentrations were associated with larger PDA and at 24 hours with larger PDA and higher left ventricular output. Infants with higher 6KPGF1 alpha concentrations were more likely to develop clinically significant PDA. There was no association between early measurements of 6KPGF1 alpha and IVH. CONCLUSIONS: Early postnatal prostacyclin concentrations are markedly raised in preterm infants, particularly in those with more severe lung disease. Raised 6KPGF1 alpha concentrations were associated with an increased ductal diameter and subsequent PDA, but not IVH.  (+info)

The snare-assisted technique for transcatheter coil occlusion of moderate to large patent ductus arteriosus: immediate and intermediate results. (6/531)

OBJECTIVES: The purpose of this study was to evaluate the feasibility, safety and efficacy of using a snare-assisted technique to coil occlude the moderate to large size patent ductus arteriosus (PDA). BACKGROUND: Transcatheter occlusion of small PDAs using Gianturco coils is safe and effective. However, in larger size PDAs and/or those with short PDA length, the procedure still carries risks of coil embolization, incomplete occlusion and failure to implant the coil. METHODS: From January 1994 to June 1997, the records of 104 consecutive snare-assisted coil occlusions of moderate to large PDAs (minimum diameter >2.0 mm) were reviewed. Immediate and intermediate outcomes including complete and partial occlusion, failure to implant and complications were analyzed with respect to ductal type and size. RESULTS: Patient age ranged from 0.1 to 70.1 years (median 3.3 years). Minimum PDA diameter ranged from 2.1 to 6.8 mm (mean 3.0 +/- 0.9 mm). Angiographic types were A-62, B-13, C-6, D-14 and E-9. Using the snare-assisted technique, coil placement was successful in 104/104 patients (100%), irrespective of size or angiographic type. Immediate complete closure was observed in 73/104 (70.2%) and was related to smaller PDA size, but not to angiographic type. Complete closure was documented in 102/104 (98.1%) at 2- to 16-month follow-up. Successful closure was unrelated to PDA size or type. Coil embolization to the pulmonary artery occurred in 3/104 (2.9%) patients and was not related to PDA size or type. The need for multiple coils was found in 28/104 patients (26.9%), and was related to larger PDA size, but not to angiographic type. CONCLUSIONS: The snare-assisted delivery technique allows successful occlusion of moderate to large PDAs up to 6.8 mm, irrespective of angiographic type. This technique permits improved control and accuracy of coil placement, and facilitates delivery of multiple coils.  (+info)

Lung perfusion studies after detachable coil occlusion of persistent arterial duct. (7/531)

OBJECTIVE: To evaluate relative lung perfusion following complete occlusion of persistent arterial duct with detachable Cook coils. METHODS: Ductal occlusion using detachable coils was performed in 35 patients (median age 3.9 years, range 0.5 to 16; 32 native ducts, three patients with previous devices). If the duct could be crossed with a 0.035 inch guidewire and a 4 F catheter after coil implantation, a further coil was implanted. Between one and seven coils were used (median two). RESULTS: Complete ductal occlusion was confirmed by echocardiography 24 hours after the procedure in all patients. Lung perfusion scans were performed three months after the procedure in 33 of 35 patients (two older patients with a single coil each did not attend). Decreased perfusion to the left lung (defined as < 40% of total lung flow) was observed in only one patient, who had previously had a 17 mm Rashkind umbrella implanted. There was no correlation between left lung perfusion and peak left pulmonary artery Doppler velocities (r = 0.27 and p = 0.125 for the entire group; r = 0.29 and p = 0.124 after excluding patients with previous devices). CONCLUSIONS: Coil occlusion is effective in achieving complete closure of the duct. An aggressive approach using multiple coils did not compromise perfusion to the left lung.  (+info)

Critical pathways for postoperative care after simple congenital heart surgery. (8/531)

OBJECTIVE: To evaluate the clinical, financial, and parent/patient satisfaction impact of critical pathways on the postoperative care of pediatric cardiothoracic patients with simple congenital heart lesions. STUDY DESIGN: Critical pathways were developed by pediatric intensive care nurses and implemented under the direction of pediatric cardiothoracic surgeons. PATIENTS AND METHODS: Critical pathways were used during a 12-month study on 46 postoperative patients with simple repair of atrial septal defect (ASD), coarctation of the aorta (CoA), and patent ductus arteriosus (PDA). Using the study criteria, a control group of 58 patients was chosen from 1993. Prospective and control group data collected included postoperative intubation time, total laboratory tests, arterial blood gas utilization, morphine utilization, time in the pediatric intensive care unit, total hospital stay, total hospital charges, total hospital cost, and complications. Variances from the critical pathway and satisfaction data were also recorded for study patients. RESULTS: Resource utilization was reduced after implementation of critical pathways. Significant reductions were seen in total hours in the pediatric intensive care unit, total number of laboratory tests, postoperative intubation times, arterial blood gas utilization, morphine utilization, length of hospitalization (ASD, 4.9 to 3.1 days; CoA, 5.2 to 3.2 days; and PDA, 4.1 to 1.4 days; all P < 0.05), total hospital charges (ASD, $16,633 to $13,627; CoA, $14,292 to $8319; and PDA, $8249 to $4216; all P < 0.05), and total hospital costs. There was no increase in respiratory complications or other complications. Patients and families were generally satisfied with their hospital experience, including analgesia and length of hospitalization. CONCLUSIONS: Implementation of critical pathways reduced resource utilization and costs after repair of three simple congenital heart lesions, without obvious complications or patient dissatisfaction.  (+info)

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

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. MAIN OUTCOME MEASURES: In group A colour flow Doppler echocardiography showed that complete occlusion ...

S.. PY - 1985/1/1. Y1 - 1985/1/1. N2 - The effect of indomethacin on carbohydrate metabolism was studied in 6 premature infants with significant patent ductus arteriosus (mean ± S.D., birth weight 1,066 ± 244 gm, gestational age 30 ± 1.6 weeks). All infants were in a glucose steady state between 50 and 100 mg/dl over a 2-hour period before indomethacin administration. There was a significant fall in plasma glucose at 1, 6, 12, and 24 hours following intravenous indomethacin infusion. Since there was no significant change in insulin levels from the baseline, the mechanism of indomethacin-mediated lack of prostaglandin inhibition of insulin release was not substantiated. Based on this study, plasma glucose levels should be followed closely in the first 24 hours following intravenous indomethacin ...

|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

Background Data: Controversy exists regarding the best method of managing very low birth weight infants with PDA and whether to employ medical management using INDO or surgical ligation of the ductus. Methods: Two hundred fifty-two premature infants with symptomatic PDA were given intravenously INDO 0.2 mg/kg every 12 hours x 3 in an attempt to close the ductus. Patients were evaluated for sex, birth weight, gestational age, ductus closure, occurrence of NEC, bowel ...

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 ...
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. ...
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 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 ...
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.. ...

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 ...
Patent ductus arteriosus (PDA), where the ductus arteriosus fails to close after birth, is rare in healthy term newborns. As gestational age decreases, the incidence of PDA increases.
The ductus arteriosus is a blood vessel that connects two major arteries before birth and normally closes after a baby is born. If it stays open, the result is a condition called patent ductus arteriosus (PDA).

Clear-cut clinical evidence of a haemodynamically significant patent ductus arteriosus should be present, such as respiratory distress, a continuous murmur, a hyperactive precordium, cardiomegaly and pulmonary plethora on chest x-ray.
Patent ductus arteriosus (PDA) is a congenital heart defect that occurs when the patent ductus doesnt close. Learn about PDA, including how it affects children and how we perform PDA repair here.
Patent ductus arteriosus (PDA) is presented in 55 to 70% of the preterm infants with a gestational age lower than 30 weeks or a birth weight lower than 1000 grams. PDA has being associated to mortality or morbidity such as ischemic or hemorrhagic cerebral events, necrotising enterocolitis, renal disfunction or poor pulmonary outcome; however, it is not clear whether these are a consequence of the PDA presence, the treatment implemented for closing it, or the immaturity of these population. PDA standard treatment (ST) consists on three doses of indomethacin or ibuprofen (10-5-5mg/kg) given 24 hours apart, being the surgical closure a second line therapeutic option. In spite of ibuprofen has been pointed as the drug of choice for PDA treatment by the last version of the Cochrane review, side effects have been associated to both medication. Standard ibuprofen treatment is based on a clinical trial where the three-dose protocol seemed to be more effective than one-dose scheme for PDA closure; ...

Char syndrome is a condition that affects the development of the face, heart, and limbs. It is characterized by a combination of three major features: a distinctive facial appearance, a heart defect called patent ductus arteriosus, and hand abnormalities.. Most people with Char syndrome have a characteristic facial appearance that includes flattened cheek bones and a flat nasal bridge (the area of the nose between the eyes). The tip of the nose is also flat and broad. The eyes are wide-set with droopy eyelids (ptosis) and outside corners that point downward (down-slanting palpebral fissures). Additional facial differences include a shortened distance between the nose and upper lip (a short philtrum), a triangular-shaped mouth, and thick, prominent lips.. Patent ductus arteriosus is a common heart defect in newborns, and it occurs in most babies with Char syndrome. Before birth, the ductus arteriosus forms a connection between two major arteries (the aorta and the pulmonary artery). This ...

There is great discussion about non-confluent pulmonary artery (PA) reconstruction, and several materials have been used. Autologous pericardium is considered feasible for infectious resistance, autoimmune response, extensibility, and growth potential. The patient was born at 39 weeks (body mass = 2550 g). He was diagnosed with tetralogy of Fallot, pulmonary atresia, non-confluent PA, and bilateral patent ductus arteriosus. Right and left Blalock-Taussig shunts with patent ductus arteriosus ligations were placed on day 27 and 3 months, respectively. At 19 months (8.8 kg), definitive repair was performed with tricuspid valved conduit concurrent with PA reconstruction using an autologous pericardium roll conduit. The autologous pericardium was treated with glutaraldehyde (autologous pericardium fixed with 0.4% glutaraldehyde for 7 min and rolled as conduit - 12 mm in diameter and 30 mm in length). Following an incision on the visceral side of the PAs before the 1st branch, the autologous pericardial roll
BackgroundPost-ligation cardiac syndrome (PLCS) is a common complication of patent ductus arteriosus (PDA) surgical closure in low birth weight infants. It has been associated with mortality, but there is a lack of information about the neurodevelopmental outcome of the survivors. We aimed to explore the prevalence of PLCS and to assess whether this clinical condition is a risk factor for adverse outcome, (moderate or severe neurodevelopmental disabilities).MethodsWe retrospectively reviewed the medical charts of all the infants | 30 weeks of gestation who underwent ductus arteriosus ligation at our unit between 2005 and 2009.ResultsDuring the study period, 39 preterm infants [mean gestational age 26.4 (2) weeks] underwent surgical closure of the PDA at a mean postnatal age of 25.3 (2.3) days. Twenty six percent of the study population developed PLCS. Five infants died and the follow-up was accomplished in 24 infants (70% of the survivors) at a mean age of 5.3 (1.5) years (range 2-9 years).
The prevalence rate for cardiovascular malformations in dogs presented to a large university veterinary clinic was 6.8 per 1000. Patent ductus arteriosus, as in man, was found predominantly in females. Breed-specific prevalence rates were significantly greater in purebred dogs than in mongrels, and the breed distributions of patent ductus arteriosus, pulmonic stenosis, subaortic stenosis, persistent right aortic arch, and tetralogy of Fallot were significantly different than would be expected if all breeds were equally susceptible to each type of malformation. On the basis of these observations, two hypotheses were made: (1) Genetic factors are determinants of certain types of congenital heart disease in the dog. (2) These genetic factors have specific effects on cardiac morphogenesis, resulting in specific types of cardiovascular malformations. Preliminary genetic studies confirmed the specific hereditary transmission of valvular pulmonic stenosis in beagles, persistent right aortic arch in ...
In patients where the patency is quite large and thus offers little resistance to blood flow, large volumes of blood can undergo left-right shunting from the aorta to the pulmonary artery. Because shunted blood must ultimately return to the left heart, over time the left heart undergoes volume overload and enters a spiral of left heart failure. Additionally, through poorly-understood processes chronically increased blood flow through the pulmonary circulation due to left-right shunting results in pulmonary hypertension which can increase the pulmonary vascular resistance beyond that of systemic vascular resistance] and ultimately lead to reversal of the shunt. This physiological scenario, termed Eisenmengers Syndrome, yields a right-left shunt can result in hypoxemia and symptomology of cyanosis at this late stage ...

N2 - This paper introduces a very general and flexible model for the study of hemodynamic changes in congenital heart disease. The generality of the model makes it possible to use the same computer program (which is included in an Appendix) to study both the fetal circulation and the adult circulation, as well as such diverse disease states as patent ductus arteriosus, ventricular septal defect, atrial septal defect, tetralogy of Fallot and transposition of the great arteries. In this paper, only patent ductus and ventricular or atrial septal defect are studied, with special emphasis on the influence of increasing pulmonary vascular resistance on the shunt flow. In the case of patent ductus and ventricular septal defect, the computed shunt flow is very time-dependent and the left-to-right shunt becomes first ...
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.
Results: Seventy dogs and 13 cats underwent lateral thoracotomy. Sixty-two per cent of cats and 91 per cent of dogs survived to discharge. Survival to discharge was significantly lower in cats than dogs, for neoplastic than non-neoplastic disease and in older animals. Survival to discharge was higher in animals undergoing patent ductus arteriosus ligation than in those undergoing lung lobectomy or oesophageal surgery. Survival to discharge was not related to surgeon experience. The incidence of complications was not related to species, age, disease, duration of surgery, surgeon experience or duration of thoracostomy tube placement. A low complication rate (5 per cent) was associated with thoracostomy tubes. ...

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.. ...
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 ...

B type natriuretic peptide (BNP) is mainly synthesized in the ventricles of the heart and released in response to volume and pressure loading and ventricular stress and, therefore, plays an important role in regulation of extracellular fluid volume. BNP causes diuresis, natriuresis, arterial and venous vasodilation and antagonizes the renin-angiotensin system resulting in a reduction in intravascular volume and decreased ventricular preload and afterload.. In adults, BNP levels have been routinely used to diagnose and measure the degree of congestive heart failure. In healthy term infants, BNP levels are initially elevated in the first few days of life but then decline over the ensuing week after birth to near adult levels by 3 months of age. However, in premature newborn infants there are still no normative values for BNP and, therefore, no agreed-upon cut off points to diagnose ventricular overload without confirmatory echocardiography. Patent ductus arteriosus (PDA) is the most common cause ...
Our case can be classified as complex coronary arteriovenous fistulas with termination in the pulmonary trunk with multiple vessels of origin (LCA, RCA and anomalous coronary artery). The dilated costobronchial vessel of origin can be thought of as an extracardiac systemic-to-pulmonary artery collateral vessel or isolated aortopulmonary collateral artery (IAPCA), the coronary supply from RCA & LAD fits the MAPCA definition as well, although intersegmental arteries (typical tortuous posterior hilar vessels) are absent, drainage this proximal in the pulmonary trunk is odd and most isolated MAPCAs would have regressed. [5] Since no cardiac abnormalities were noted indicating an aetiological factor, this persistent left-to-right shunt is probably congenital. The exact aetiology remains challenging, patients history was unremarkable for patent ductus arteriosus or chronic lung disease. [6 ...
The pattern of dye dilution curves and the cardiac output was studied in 29 healthy newborn infants during the first 26 hours of life by the method of Wood and his associates. Thirty-six per cent of all infants studied had curves of normal contour which occurred mostly in infants older than 15 hours. Infants younger than 15 hours tended to have curves of abnormal shape. These were either diphasic or had the appearance of curves associated with left-to-right shunts and were probably caused by a patent ductus arteriosus. The mean cardiac output was 540 cc. per minute.. ...
Congenital heart diseases occur in at least 10 per 1000 live-born children; the incidence is much higher in stillborn infants and in spontaneous abortuses. This figure excludes bicuspid aortic valves, patent ductus arteriosus in premature infants, and tiny muscular ventricular septal defects with respective incidences of 10 to 20, 4 to 5, and 30 to 40 per 1000 live-born children. The distributions of various common types of congenital heart diseases at birth are given in Table 484-1. ...

All infants required supplemental O2 (mean FIO2 35%) to maintain adequate systemic oxygenation (Pao2 greater than 50 mm Hg). None of the infants had evidence of a patent ductus arteriosus at the time of examination. Echocardiographic measurements of left and right ventricular systolic time intervals revealed normal systolic time interval ratios suggesting normal left ventricular systolic function as well as normal ...
A premature neonate with gestational age of 32 weeks and birth body weight of 1650 grams was diagnosed to have type A interrupted aortic arch, perimembranous type ventricular septal defect, atrial septal defect, and patent ductus arteriosus. One-stage complete reconstruction of aortic arch and concomitant repair of intracardiac defects was performed at age of 13 days with body weight of 1600 grams. Through innominant artery and retrocardiac descending aorta cannulation for continuous cerebral and lower body perfusion, deep hypothermic circulatory arrest was avoided. Postoperative renal function was excellent, and there were no neurological sequelae after 24 months follow-up.

OBJECTIVES. Congenital cardiac defects (CCD) are the most common heart diseases in dogs of less than 1 year of age. The exact prevalence of CCD is uncertain as there are both national and regional differences for certain cardiovascular malformations. Because multiple congenital anomalies may be present in the same dog the chosen method of reporting defects will alter frequency data. The three most common CCD reported in dogs in USA and UK have been patent ductus arteriosus (PDA), (sub)aortic stenosis and pulmonic stenosis (PS). However, most recent reports indicate that subaortic stenosis (SAS) is the most common CCD in dogs in many regions of the world. The aim of this report is to characterize the prevalence of different types of CCD in a population of dogs in the south east of Spain. MATERIALS. This retrospective study was performed in 80 dogs presented between 1994 and 2001 to Veterinary Teaching Hospital of University of Murcia (Spain) and diagnosed with CCD. A complete information about ...
Background Although several different types of natural surfactants are available, including Alveofact, Curosurf, and Survanta, the preferred type and the magnitude of their effects are unknown.Objectives This study was designed to compare the effects of these three surfactants on the gas exchange and clinical outcomes of neonates with respiratory distress syndrome (RDS).Methods This triple-blind randomized clinical trial studied all preterm neonates ≤ 37 weeks with RDS who were admitted to the neonatal intensive care unit (NICU) of Taleghani hospital (Tabriz, Iran) between 2012 and 2013. The patients were divided into three groups, each of which received one of these surfactants. The incidences of ventilator dependency, patent ductus arteriosus (PDA), broncho-pulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), hospital-stay length, and continuous positive airway pressure (CPAP) failure, as well as blood gas levels, were recorded as endpoint measurements and
Patients suffering from pulmonary overcirculation and any type of congestive heart failure should undergo preoperative treatments. The objective of PDA Disetion is to minimize left to right shunting, reduce systematic overload and enhance cardiac function. To ensure adequate ventilation along with oxygenation, mechanical ventilator support is required. This is required for setting of pulmonary edema.. By maintaining lower fraction of oxygen and higher carbon dioxide levels during ventilation, it is possible to reduce pulmonary blood flow and even pulmonary edema. If a patient has patent ductus arteriosus, then surgery should be done to close it. This can also be done through medications.. ...

Aim: To describe the spectrum of heart disease in a large genotypically- and phenotypically-defined cohort of patients with Noonan syndrome.. Method: An international research database of patients with Noonan syndrome was combined with the medical records of all clinically-defined Noonan syndrome patients at Childrens Hospital Boston and reviewed for structural heart disease. Noonan syndrome gene mutations in PTPN11, RAF1, SOS1, SHOC2, KRAS and/or BRAF were screened for in 74.5% of the cohort.. Results: A total of 294 patients were identified with Noonan syndrome. Cardiac lesions noted included pulmonary stenosis (56.8%) atrial septal defect (32.3%), hypertrophic cardiomyopathy (16.7%), ventricular septal defect (11.9%), patent ductus arteriosus (8.8%), aortic root dilation (4.8%), aortic coarctation (2.4%) and tetralogy of fallot (1.7%). No structural heart disease was seen in 19% of patients. Of those with pulmonary stenosis, 25.7% had the valve balloon dilated in the cardiac catheterization ...
Click picture to show/hide bloodflows). Pathophysiology. In the absence of a fully functional left ventricle and/or aortic valve, preservation of systemic circulation and survival is dependent on a patent ductus arteriosus. In this case, the right ventricle takes over for the left to supply the pulmonary and systemic circuits as well as the coronary arteries and brachiocephalic veins (in a retrograde direction). The amount of blood flow to the pulmonary and systemic circulation is a function of the vascular resistance which, in turn, is influenced by the size of the interatrial orifice. Arterial defects that restrict movement cause pressure in the left atrium and pulmonary circuit to increase, and thus restrict pulmonary blood flow. Increased pulmonary blood flow brings a larger volume of oxygenated blood back to the left atrium, which then mixes with the systemic venous return in the right via the foramen ovale.. During the prenatal period all blood, aside from a small volume of pulmonary ...
My research in perinatal epidemiology focuses on cardiovascular disease in relation to preterm birth and other pregnancy complications, in both the mother and the child. Presently, I investigate how the diagnostics of patent ductus arteriosus (PDA) could be improved and how treatment of of PDA is associated to short term morbidity and complications in very preterm infants. Moreover, I am an investigator in the EPICE-project, a European FP7-financed project that studies implementation of evidence based practices in European neonatal intensive care (http://www.epiceproject.eu/en/). Another research interest is the future cardiovascular health of women that delivered preterm or had other pregnancy complications, which I currently investigate in collaboration with researchers from Umeå University, Sweden and the University of California San Francisco, USA.. ...
November is Prematurity Awareness Month. In honor of this, some parents who have had babies prematurely have offered to tell their stories to create awareness about his important cause. Our second preemie profile is an amazing little boy named Johann. Johann was born on October 23rd 2004 at only 24 weeks and 3 days, weighing a mere 698 grams(1lb 9ozs). Mom Adrienne, believes that an amniotic infection may have caused her to go into premature labor.. Adrienne says that while Johann was never the sickest child in the NICU, he did go through every preemie complication on the list. It was one thing after another and it seemed like forever for things to resolve.. Johann had a PDA(Patent Ductus Arteriosus) that resolved after receiving three drug treatments. He also had metabolic imbalances, hypoglycemia, stage 1 ROP(Retinopathy of prematurity) of his eyes, suspected NEC (Necrotizing enterocolitis), chronic lung disease, jaundice and leaky kidneys.. After 221 long days in the NICU, Johann ended up ...
Holes in the heart. Holes can form in the walls between heart chambers or between major blood vessels leaving the heart.. In certain situations, these holes allow oxygen-poor blood to mix with oxygen-rich blood, resulting in less oxygen being carried to your childs body. Depending on the size of the hole, this lack of sufficient oxygen can cause your childs skin or fingernails to appear blue or possibly lead to congestive heart failure.. A ventricular septal defect is a hole in the wall between the right and left chambers on the lower half of the heart (ventricles). An atrial septal defect occurs when theres a hole between the upper heart chambers (atria).. Patent ductus arteriosus (PAY-tunt DUK-tus ahr-teer-e-O-sus) is a connection between the pulmonary artery (containing deoxygenated blood) and the aorta (containing oxygenated blood). A complete atrioventricular canal defect is a condition that causes a hole in the center of the heart.. ...
In addition to incorporating the results from implementation studies, several other aspects of the revision deserve emphasis. First, the revised document combines TTE, TEE, and stress echocardiography, whereas the initial TTE and TEE AUC (1) were published separately from the stress echocardiography AUC (2). The indication tables still focus on each modality separately, for example, TTE (or TEE as an adjunct if TTE nondiagnostic), TEE as an initial test, and stress echocardiography. The exception is the final table (Table 18, Indications 201 and 202), which covers contrast use and is applicable to all of the echocardiographic modalities. Second, a new table was created to cover indications related to patients with adult congenital heart disease, as this patient population is being encountered with greater frequency by adult cardiologists (Table 7, Indications 92 to 98) (37). It should be noted that, with the exception of some adults with ligated or occluded patent ductus arteriosus (covered in ...

For the first time ever, veterinarians at Oklahoma State Universitys Center for Veterinary Health Sciences performed surgery on Yoda, a 15-month-old sheep, to correct a congenital heart problem called a patent ductus arteriosus or PDA.. Argyle-based Ranch Hand Rescue Counseling Center and Animal Sanctuary owns Yoda, one of several therapy animals at the center.. A PDA is a blood vessel that allows blood to bypass the lungs. At birth it should close off and now 15 months later, it is still open, explains Baumwart, a board certified veterinary cardiologist. With Dr. Robert Streeters assistance, we first tried to correct the problem by going in through a blood vessel in Yodas leg with a catheter. However, the blood vessel we wanted to close off was too large.. Baumwart handed the case over to his colleague, Dr. Danielle Dugat, a small animal surgeon.. My role was to take Yoda to surgery and open his chest where we could see his heart, the normal blood vessels and the shunting vessel, says ...
