As the child matures, the partially reconstructed pulmonary conduit increases in diameter, while the size of the reconstructed valve remains the same. As a result, follow up surgery is required to replace the undersized valve. Thus, in this project, we evaluated the in-vitro performance of a bi-leaflet valve design in terms of percentage regurgitation with increasing artery (conduit) diameters. Results revealed percentage regurgitations ranging from 13% to 34% for conduits tested. It was observed that percentage of regurgitation increased exponentially with increasing diameters. While the amount of regurgitation may seem severe, it is deemed acceptable, and this valve could potentially reduce the frequency of re-operation in the lifetime of pediatric patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20heart%20valve" title="pulmonary heart valve">pulmonary heart valve</a>, <a href="https://publications.waset.org/abstracts/search?q=tetralogy%20of%20fallot" title=" tetralogy of fallot"> tetralogy of fallot</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20polytetrafluoroethylene%20valve" title=" expanded polytetrafluoroethylene valve"> expanded polytetrafluoroethylene valve</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20heart%20valve%20replacement" title=" pediatric heart valve replacement"> pediatric heart valve replacement</a> </p> <a href="https://publications.waset.org/abstracts/86145/design-and-development-of-an-expanded-polytetrafluoroethylene-valved-conduit-with-sinus-of-valsalva" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86145.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Design and Development of a Bi-Leaflet Pulmonary Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munirah%20Ismail">Munirah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon%20Hock%20Yeo"> Joon Hock Yeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paediatric patients who require ventricular outflow tract reconstruction usually need valve construction to prevent valvular regurgitation. They would face problems like lack of suitable, affordable conduits and the need to undergo several operations in their lifetime due to the short lifespan of existing valves. Their natural growth and development are also of concern, even if they manage to receive suitable conduits. Current prosthesis including homografts, bioprosthetic valves, mechanical valves, and bovine jugular veins either do not have the long-term durability or the ability to adapt to the growth of such patients. We have developed a new design of bi-leaflet valve. This new technique accommodates patients’ annular size growth while maintaining valvular patency. A mock circulatory system was set up to assess the hemodynamic performance of the bi-leaflet pulmonary valve. It was found that the percentage regurgitation was acceptable and thus, validates this novel concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi-leaflet%20pulmonary%20valve" title="bi-leaflet pulmonary valve">bi-leaflet pulmonary valve</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20heart%20valve" title=" pulmonary heart valve"> pulmonary heart valve</a>, <a href="https://publications.waset.org/abstracts/search?q=tetralogy%20of%20fallot" title=" tetralogy of fallot"> tetralogy of fallot</a>, <a href="https://publications.waset.org/abstracts/search?q=mock%20circulatory%20system" title=" mock circulatory system"> mock circulatory system</a> </p> <a href="https://publications.waset.org/abstracts/86147/design-and-development-of-a-bi-leaflet-pulmonary-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86147.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Incidence, Pattern and Risk Factors of Congenial Heart Diseases in Neonates in a Tertiary Care Hospital, Egyptian Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gehan%20Hussein">Gehan Hussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Hams%20Ahmad"> Hams Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Baher%20Matta"> Baher Matta</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasmeen%20Mansi"> Yasmeen Mansi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Fawzi"> Mohamad Fawzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Congenital heart disease (CHD) is a common problem worldwide with variable incidence in different countries. The exact etiology is unknown, suggested to be multifactorial. We aimed to study the incidence of various CHD in a neonatal intensive care unit (NICU) in a tertiary care hospital in Egypt and the possible associations with variable risk factors. Methods: Prospective study was conducted over a period of one year (2013 /2014) at NICU KasrAlAini School of Medicine, Cairo University. Questionnaire about possible maternal and/or paternal risk factors for CHD, clinical examination, bedside echocardiography were done. Cases were classified into groups: group 1 without CHD and group 2 with CHD. Results: from 723 neonates admitted to NICU, 180 cases were proved to have CHD, 58 % of them were males. patent ductus arteriosus(PDA) was the most common CHD (70%), followed by an atrial septal defect (ASD8%), while Fallot tetralogy and single ventricle were the least common (0.45 %) for each. CHD was found in 30 % of consanguineous parents Maternal age ≥ 35 years at the time of conception was associated with increased incidence of PDA (p= 0.45 %). Maternal diabetes and insulin intake were significantly associated with cases of CHD (p=0.02 &0.001 respectively), maternal hypertension and hypothyroidism were both associated with VSD, but the difference did not reach statistical significance (P=0.36 &0.44respectively). Maternal passive smoking was significantly associated with PDA (p=0.03). Conclusion: The most frequent CHD in the studied population was PDA, followed by ASD. Maternal conditions as diabetes was associated with VSD occurrence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NICU" title="NICU">NICU</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20heart%20disease" title=" congenital heart disease"> congenital heart disease</a>, <a href="https://publications.waset.org/abstracts/search?q=echocardiography" title=" echocardiography"> echocardiography</a> </p> <a href="https://publications.waset.org/abstracts/143362/incidence-pattern-and-risk-factors-of-congenial-heart-diseases-in-neonates-in-a-tertiary-care-hospital-egyptian-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Congenital Heart Defect(CHD) “The Silent Crises”; The Need for New Innovative Ways to Save the Ghanaian Child - A Retrospective Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priscilla%20Akua%20Agyapong">Priscilla Akua Agyapong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In a country of nearly 34 million people, Ghana suffers from rapidly growing pediatric CHD cases and not enough pediatric specialists to attend to the burgeoning needs of these children. Most of the cases are either missed or diagnosed late, resulting in increased mortality. According to the National Cardiothoracic Centre, 1 in every 100,000 births in Ghana has CHD; however, there is limited data on the clinical presentation and its management, one of the many reasons I decided to do this case study coupled with the loss my 2 month old niece to multiple Ventricular Septal Defect 3 years ago due late diagnoses. Method: A retrospective cohort study was performed at the child health clinic of one of Ghana’s public tertiary Institutions using data from their electronic health record (EHR) from February 2021 to April 2022. All suspected or provisionally diagnosed cases were included in the analysis. Results: Records of over 3000 children were reviewed with an approximate male to female ratio of 1:1.53 cases diagnosed during the period of study, most of whom were less than 5 years of age. 25 cases had complete clinical records, with acyanotic septal defects being the most diagnosed. 62.5% of the cases were ventricular septal defects, followed by Patent Ductus Arteriosus (23%) and Atrial Septal Defects (4.5%). Tetralogy of Fallot was the most predominant and complex cyanotic CHD with 10%. Conclusion: The indeterminate coronary anatomy of infants makes it difficult to use only echocardiography and other conventional clinical methods in screening for CHDs. There are rising modernizations and new innovative ways that can be employed in Ghana for early detection, hence preventing the delay of a potential surgical repair. It is, therefore, imperative to create the needed awareness about these “SILENT CRISES” and help save the Ghanaian child’s life. <p class="card-text"><strong>Keywords:</strong> <a
