The Burden of Neonatal Referrals on a Pediatric Cardiology Service: A Local Center Experience.

BACKGROUND: Congenital heart disease (CHD) is a common occurrence in live births, with some exhibiting critical congenital heart disease; therefore, cardiology services should be available around the clock to ensure timely diagnosis and management. This study aims to describe the workload and the need for pediatric cardiac services in a maternity hospital for newborn referrals. Moreover, the study describes the indications for neonatal cardiology consultations. METHODS: The prospective cohort study was conducted over four months, from January to April 2022, in the Prince Sultan Cardiac Center Al Qassim region of Saudi Arabia. Prince Sultan Cardiac Center's pediatric cardiology department provides cardiac services to the Maternity and Children Hospital Buraidah Al Qassim. Out of the total 2,606 live births during the study period, the cardiology team evaluated 352 neonates. Neonates less than 30 days of age who were born in the maternity hospital were enrolled in the study. The outborn babies referred from other centers as suspected congenital heart disease for whom a cardiac evaluation was done were excluded. In addition, babies assessed in the emergency room and born elsewhere were excluded. Only new consultations have been considered, excluding follow-up consultations. STATISTICAL ANALYSIS: Data about patients' demographic, clinical and echocardiographic findings were recorded on Google Forms and converted to a Google spreadsheet. The Google spreadsheet's inbuilt statistical software was used for analysis. Categorical data were presented as percentages, and numerical data as median and range. RESULTS: The cardiology team evaluated 352 neonates from 2,606 live births over four months, accounting for 13.5 per 100 live births. The median weight was 2.8 kilograms, with a 0.5-4.3 kilogram range. Males comprised 187 (53%), and females comprised 165 (47%). Moreover, full-term, preterm, and post-term accounted for 236 (67%), 113 (32%), and 3 (0.8%) of patients, respectively. The common indications for neonatal cardiac referral were respiratory distress 60 (17%), infants born to diabetic mothers 50 (14%), abnormal fetal echocardiogram 49 (13.9%), family history of abortion or neonatal death 31 (8.8%), and congenital anomalies 30 (8.5%). Systolic murmur was the commonest clinical finding that prompted cardiology referrals 82 (23.2%), followed by desaturation 38 (10.7%) and dysmorphic features 31 (8.8%). Among the congenital cardiac defects, an isolated atrial septal defect (ASD) was seen in 66 (18.5%), isolated patent ductus arteriosus in 50 (14.2%), and ventricular septal defect in 21 (5.9%). Moreover, 13 (4.4%) lesions were critical CHDs. Finally, 27 (7.6%) had a diagnosis of pulmonary hypertension. CONCLUSION: Knowing the burden of neonatal cardiac assessment on pediatric cardiology services in any maternity center may help the healthcare authorities to allocate resources and optimize the delivery of cardiac services among the neonatal population. Properly allocating pediatric cardiologists to the needed centers may optimize neonatal cardiac services. Moreover, it may decide on the number of pediatric cardiologists that need to be trained each year to meet the requirements of neonatal cardiac services.

Comparison of Demographic, Clinical, and Echocardiographic Features Between Complete and Incomplete, and Early and Late Presenters of Kawasaki Disease: A 10-Year Single-Center Experience.

INTRODUCTION:  The diagnosis of Kawasaki disease (KD) is based mainly on clinical findings and supported by laboratory tests. Complete KD fulfills the main clinical criteria, while incomplete KD includes patients with fewer main criteria and compatible laboratory or echocardiographic findings. The study compares the demographic, clinical, laboratory, and echocardiographic parameters between the complete and incomplete KD and early and late presenters. Moreover, it describes the coronary manifestations of the study population. METHODOLOGY: A retrospective review of all patients admitted with a diagnosis of KD during the period from January 2010 to September 2020 was conducted. Clinical presentation, laboratory features, echocardiographic observations, and follow-up data were examined. Moreover, the patients were further classified as early presenters (presented within 10 days of fever onset) and late presenters (presented after 10 days of disease onset). A comparison between complete and incomplete KD and early and late presenters was performed for demographic, clinical, and echocardiographic features. RESULTS: A total of 76 patients were admitted with a diagnosis of KD. The median age of presentation was 28 months, with a range of five to 144 months, and the median timing was seven days, with a range of one to 30 days. The median follow-up period was six weeks, with a range of one to 192 weeks. Complete KD was present in 38 patients (50%), and 38 (50%) had incomplete KD. Skin manifestations, oral mucosal changes, skin desquamation, conjunctivitis, and lymphadenopathy were present more in patients with complete KD than incomplete ones. Complete and incomplete diseases did not differ regarding coronary artery lesions. Of the patients, 53 (70%) presented 10 days or less after the onset of fever, and 23 (30%) presented after the 10th day of disease onset. Comparison between early and late presenters revealed significantly greater mucus membrane changes and lymphadenopathy manifestations among the early presenters and coronary artery lesions among the late presenters. CONCLUSION: The clinical features of KD should prompt early referral for evaluation, echocardiography, and early administration of intravenous immunoglobulin to prevent coronary artery complications. The complete form of Kawasaki does not have more frequent coronary artery lesions than the incomplete form. Additionally, late presenters may be at increased risk for coronary artery abnormalities than early presenters.

The Impact of Integration of a Genetic Clinic Into a Pediatric Cardiac Unit.

BACKGROUND: Previously published studies suggest that genetic or environmental causes can be observed in 20-30% of congenital heart disease (CHD) patients, which include aneuploidy, single gene defects, pathological copy number variations, and de novo autosomal dominant and recessive inheritance. Moreover, the genetic background of childhood cardiomyopathies (CMs) has not been elucidated well. OBJECTIVE: The study highlights the value of genetic assessment in diagnosing and family counseling for CHD and pediatric CM patients referred to the genetic clinic in a pediatric cardiology department. METHODS: The study involved patients less than 18 years of age attending the cardiogenetic clinic in the pediatric cardiology department between December 2010 and February 2019. The following patient categories who had genetic evaluation were included: CHD in the presence of a syndromic phenotype, patients with CHD having extracardiac congenital anomalies or delayed development, hypertrophic and dilated CM patients, patients with dilated aortic root and ascending aorta, significant CHD in siblings or first-degree relatives, suspected channelopathies; and interrupted aortic arch abnormalities. RESULTS: A total of 285 patients were evaluated in the cardiogenetic clinic. The mean age was 20.2 months, with a range of 0-168. Females and males constituted 153 (53.7%) and 132 (46.3%), respectively. The most common cause of referral to the genetic clinic was the presence of CM (N=134 (46.3%)): hypertrophic CM in 24% and dilated CM in 20% of cases. Seventy-six patients (26.7%) had positive genetic results. The most common genetic abnormality was familial infantile hypertrophic CM-causing gene ELAC2 in 19 (23.5%) cases. CONCLUSION: It may be beneficial for any pediatric cardiology unit to provide an established genetic clinic. Using a genetic clinic will enhance understanding of CHD pathophysiology, family education, and genetic counseling. Agreement on a well-written protocol and the way forward to specify what congenital heart conditions require genetic investigation should be clarified.

Radiation Dose Exposure to Patients During Transcatheter Patent Ductus Arteriosus Closure via the Arterial Route.

Objective This study aims to evaluate the radiation dose for transcatheter patent ductus arteriosus (PDA) via the arterial route and compare it with previously published benchmarks. Background Exposure to radiation in the catheterization lab can cause skin injury and cancer in the long run, especially in pediatric patients with complex heart conditions, which necessitate serial catheterizations. Therefore, measuring the patient radiation dose and establishing a benchmark for each cardiac interventional procedure is essential. Material and methods In this prospective study, 34 patients with transcatheter patent ductus arteriosus closure via an arterial route were included. Patients who had silent PDAs, no left heart dilatation and PDA size of less than 2mm had PDA closed via an arterial route. All the study group patients received an Amplatzer duct occluder II-additional size device (St. Jude Medical Corp, St. Paul, MN) using biplane flat-panel fluoroscopy equipment adjusted in accordance with the pediatric parameters. Patients' dose area product, air kerma and fluoroscopy time were recorded in the catheterization lab and finally compared with internationally published reference data. Results Of 73 patients who had transcatheter patent ductus arteriosus closure between April 2021 to December 2021, 34 patients who had a PDA closure via an arterial route were enrolled. The median age and weight were 11.5 (4-168) months and 10.5 (6-31) kg. Twenty-one (61.8%) were males, and 13 (38.2%) were males. The median radiation dose parameters were as follows: air kerma 11 (3-42) milliGray, dose area product 131 (33-443) microGray per m2, median dose area product indexed to weight 12 (1-48) microGray m2 per kg, fluoroscopy time 2 (2-4) min and frame rate 15 (7.5-15) frames per second. Due to many factors, our radiation dose parameters were less than internationally published reference values for transcatheter PDA closure. Conclusion Patient selection, detailed pre-catheterization echocardiography and procedure planning are essential for accomplishing device closure of PDA with a significant reduction in radiation dose. Hemodynamic assessment in the catheterization lab is unnecessary for most PDA patients. Additionally, a next-generation imaging platform equipped with flat-panel detectors and adjusted for pediatric settings and a fluoro recording option can be used to reduce radiation exposure.

Catheter Closure of Clinically Silent Patent Ductus Arteriosus Using the Amplatzer Duct Occluder II-Additional Size: A Single-Center Experience.

Objectives Transcatheter closure is the treatment of choice for most patent ductus arteriosus (PDA) in infants, children, and adults. However, there is a controversy regarding transcatheter closure of clinically silent PDAs. Some authors favor device closure to eliminate the lifelong risk of infective endarteritis while others recommend avoiding PDA closure in such patients. The study describes our experience of closing the silent PDAs using the Amplatzer duct occluder II-additional size (ADO II-AS) (St. Jude Medical Corp, St. Paul, MN). Materials and methods From April 2018 through March 2021, 52 consecutive pediatric patients aged 18 years and less with clinically silent PDA who had transcatheter closure at our center were enrolled. Patients were excluded if they had clinically detected PDAs; had surgical ligation of PDA with no residual shunt; had left heart dilatation on echocardiography; or moderate-sized PDAs closed with ADO II-AS. In addition, patients with an innocent murmur or murmur due to an associated lesion were included. This study was retrospective, and all of the 52 patients underwent PDA device closure using ADO II-AS. Results Fifty-two consecutive patients were enrolled with a median age of 17 months, range (97-2.5) 94.5 months. Mean weight was 11.29 kilogram, range (24.8-3.5) 21.3 kilogram, and mean follow-up was 13.5 months, range (29-0) 29 months. Thirty-one (59.6%) were females, and 21 (40.4%) were males. The mean procedure time was 30.6 min, range (60-10) 50 min, and mean fluoroscopic time was 5.5 min, range (28-1.7) 26.3 min. The mean volume of contrast given was 9.1 milliliter, range (30-4) 26 milliliter. Forty-five (45; 88.2%) patients had immediate closure of PDA. No patients had anesthetic or vascular complications; however, two patients had procedural complications. Device placement was unsuccessful in one patient with Downs syndrome. The mean follow-up for our patients was 13.5 months, range (29-0) 29 months; the patients were asymptomatic at the follow-up, and none of the patients had any residual leak. None of the patients showed coarctation or left pulmonary artery stenosis at the latest follow-up. Conclusion The usefulness of catheter-based therapy for silent PDA is less well-established by current evidence. Further studies are needed to justify the intervention solely based on the premise that the silent duct is a substrate for infective endarteritis; however, our reason to close silent PDA was to do so primarily because of social reasons. This study found that device closure of silent PDA is safe and effective using an ADO II-AS device with minimal risk of embolization and a low residual shunt rate. Coils have been used to close small PDAs, however, with higher rates of embolization and device malpositioning. We believe ADO-II AS offers an advantage of safety and efficacy over coils. In addition, the study highlights the advantage of using an ADO II-AS device, which can be delivered via a four French delivery system with no arterial complications.

Healthcare productivity, and its sociodemographic determinants, of Saudi female nurses: A cross-sectional survey, Al-Qassim, Saudi Arabia, 2017.

BACKGROUND: In Saudi Arabia, cultural and language differences between expatriate nurses and patients affect the quality of nursing care. Hence, the Kingdom is eying Saudization in this field. The productivity of nurses can affect the productivity of the whole health system. The aim of this study was to investigate the health-care productivity of Saudi female nurses and socio-demographic determinants of their productivity. METHODS: We conducted a cross-sectional survey of 256 randomly selected Saudi female nurses in the Qassim region. The nurses who were not working in public hospitals; not giving direct patient care or had <1-year patient-care experience were excluded from the study. The nurses' work productivity was measured using a 17-item index. RESULTS: The mean age of the nurses was 30.2 ± 5.6 years. Among the nurses, 62.6% were currently married, 33% were never married, and 4.4% were divorced/widowed. Most of the nurses were not willing to serve male patients (70.3%); they wanted to work only in female units (66.1%) and did not prefer night shifts (50.8%). Over the past 1 year, most of them demonstrated tendency of taking emergency leave (64.2%) and sick leave (56.4%), while 27.3% had unexcused absences and 19.5% had unplanned but excused absences. In addition, 20.3% demonstrated a tendency of taking frequent breaks during duty hours and 18.9% demonstrated tendency of being late on duty. Multivariable linear regression analysis revealed that being married was associated with 1.66 points decrease in the productivity index score when compared to never married nurses. Having one more child under 5 years of age was associated with 0.75 points increase in the productivity index score. In addition, nurses who employed household workers at home scored 1.04 points less than those who did not. CONCLUSIONS: Healthcare productivity index score was lower among married Saudi female nurses than never married nurses. However, aspects of married life commonly believed to cause home work-life conflicts, such as number of children, living with or without family, having disabled children in household and personal factors such as age did not have statistically significant influence on the productivity index score. It is possible that unexplained cultural issues associated with being married may be responsible for a lower productivity index score among married female nurses in Saudi Arabia.

Two-dimensional echocardiographic predictors of coarctation of the aorta.

BACKGROUND: Coarctation of the aorta is a very common congenital heart malformation. It is frequently associated with other abnormalities. Echocardiography is the diagnostic modality for congenital heart disease. The carotid-subclavian artery index and the isthmus/descending aorta index were proposed for establishing the diagnosis of coarctation of the aorta. OBJECTIVES: The objectives were to evaluate such indexes and to look for other echocardiographic predictors of coarctation of the aorta. METHOD: Echocardiography was reviewed for infants with coarctation of the aorta, as well as a control group, using the Echo PAC Dimension. Standard measurements were obtained from different sites of the aortic arch. RESULTS: A total of 31 infants 3 months or less with coarctation of the aorta and 50 infants with no coarctation of the aorta were reviewed. Abnormal aortic valve was present in 65% of those with coarctation of the aorta. The diameters of the proximal and the distal transverse aortic arch were smaller in the coarctation of the aorta group. The distance between the aortic arch branches was longer in the coarctation of the aorta group. Apart from the ratio between distance 2 and the ascending aorta, other ratios/indexes were smaller in the coarctation of the aorta group than in the control group. CONCLUSION: The presence of abnormal aortic valve, a carotid subclavian index <1.1, I/AAo ratio <0.53, and DTA/AAo ratio <0.6 suggest the presence of coarctation of the aorta. Neonates with large patent ductus arteriosus and any of these findings need close observation until the patent ductus arteriosus closes. If the arch is difficult to assess by two-dimensional echocardiography, the patient may need further imaging to rule out coarctation of the aorta.

Efficacy of implementation of a 5 scale pediatric triage and acuity scale in pediatric emergency, Saudi Arabia.

OBJECTIVES: To evaluate the effectiveness of implementation of the pediatric Canadian Triage and Acuity Scale (Ped-CTAS) for children visiting the pediatric emergency department (ED). METHODS: This cross-sectional study evaluated all children presented to the ED during a 9-day period in March 2010. The Ped-CTAS triage system was used. Triage performance was analyzed on the basis of quality indicators, rate of admissions, rate of referral, observation duration, and relationship between investigations requested and CTAS level. RESULTS: During the study period, 3,337 patients were triaged. Overall, 4 patients (0.1%) were in triage level 1, 356 (12%) were level 2, 655 (22%) were level 3, 1810 (60%) were level 4, and 189 (6%) were level 5. The left without being seen rate was 6.25%. A triage duration of 5 minutes or less was carried out for 97% of cases. Within the CTAS time objectives, the waiting time to nurse and physician was 100% for cases triaged to level 1. The proportion of cases who needed observation was 100% for level 1, 85% for level 2, 53% for level 3, 33% for level 4, and 26% for level 5. The proportion of patients admitted to the hospital was 100% for level 1. The lower the level (more acute and emergent the condition) the more use of the laboratory and radiological investigations. CONCLUSION: The pediatric CTAS triage system is a good tool for categorizing pediatric patients attending the ED. Stratified by triage level, triage indicators can be used as indicators of ED performance.

Maternal knowledge and use of folic acid among Saudi females.

OBJECTIVE: To explore and find out the level of awareness regarding folic acid's (FAs) importance, current use, and timing of administration among pregnant Saudi females. METHODS: This is a cross-sectional study conducted randomly among women aged 18-45 years old, attending the Antenatal and Gynecology Clinics at the Maternity and Children's Hospital, Al-Qassim, Kingdom of Saudi Arabia from January to November 2012. A total of 1250 subjects were approached, and 1000 women expressed their verbal consent to participate. The questionnaire consisted of 17 items, and results were analyzed using univariate and multivariate analysis. RESULTS: A total of 88.4% of women were aware of FA. However, only 4.4% of them took FA before pregnancy. Compared to highly educated women (20.4%), only 5% of illiterate women use FA during the first trimester of their pregnancy. Univariate and multivariate analysis showed that educational level had a significant association with FA awareness and use (p=0.001; odds ratio: 0.000; 95% confidence interval: 1.001 to 1.080). Most women recall hearing of FA from their doctors. Only 48 women reported a history of a previous child with congenital anomalies, and 4 of them (8.3%) of them used FA before pregnancy. CONCLUSION: We found that only 4.4% of the studied women use FA in their preconceptional period. The higher the educational level, the more the knowledge, and frequent use of FA. Poor level of awareness among lower educated woman requires medical authorities to broadcast the importance of FA, and there may be a need to fortify food with FA.

Amplatzer septal occluder and atrioventricular block: A case report and literature review.

Transcatheter closure of secondum atrial septal defect (ASD) is an alternative option to open heart surgery with good short and long-term outcomes. For this purpose, the Amplatzer septal occluder (ASO) device is widely used. Arrhythmias are known complications of ASD device closure including atrial ectopy and heart block. We report a seven-year-old female patient who developed second degree atrioventricular block (AVB) within few hours after ASD device closure using ASO device. At the seventh post-procedure day; while under close observation; patient regained sinus rhythm which was maintained thereafter. A 3-day course of prednisolone was given.

Social impact on families of children with complex congenital heart disease.

BACKGROUND AND OBJECTIVES: The care of children with complex congenital heart disease creates emo.tional and financial hardships for their families. We evaluated the social impact on families of patients with complex congenital heart disease (CHD) who underwent single ventricle repair. DESIGN AND SETTING: Cross-sectional survey conducted at the pediatric cardiology outpatient department at Prince Sultan Cardiac Center-Qassim (PSCC-Q). PATIENTS AND METHODS: All patients diagnosed and treated for complex CHD of single ventricle patho.physiology and seen in the pediatric cardiology at PSCC-Q were eligible for the study. Families of these patients completed a questionnaire conducted by one interviewer. The Impact on Family Scale (IFS) questionnaire of Stein and Riessman was instituted. Patients were divided into two groups according to the cardiac diagnosis and the requirement for medical or surgical management. The first group included patients with CHD who do not need any medical or surgical intervention, .e.g. tiny VSD or small ASD. The second group included patients with complex CHD with single ventricle pathophysiology who underwent Glenn and/or Fontan procedures. The mean impact on family scores was compared among the different groups by two sample t test analysis. RESULTS: Families of 41 children with CHD were interrogated during the study period from September 2011 to February 2012. Patients were divided into two groups. Group one (20 patients, 49%) with simple CHD and group two (21 patients, 51%) with complex CHD who are managed in the univentricular tract. Families of chil.dren who underwent single ventricle repair had significantly higher IFS (mean and standard deviation of 62 [7]) than families with minor heart disease (mean of 51 [4]) (P=.005). CONCLUSION: Families of patients who underwent single ventricle repair have significant social impact be.cause of their child illness. A supporting public group should be initiated and encouraged.

Safety and usefulness of outreach clinic conducted by pediatric echosonographers.

BACKGROUND: Outreach echocardiographic services led by cardiac sonographers may help district level hospitals in the management of patients suspected to have cardiac anomalies. However, the safety and utility of such an approach is not tested. METHODS: We retrospectively reviewed our experience of patients seen in the outreach visits by the echocardiographers alone and subsequently reviewed in the pediatric cardiology clinic. Comparison between the diagnosis made by the echocardiographer and the consultant pediatric cardiologist were done. We defined safety as no change in patient management plan between the outreach evaluation and the pediatric cardiology clinic evaluation, and we defined usefulness as being beneficial, serviceable and of practical use. RESULTS: Two senior echocardiographic technicians did 41 clinic visits and over a period of 17 months, 623 patients were seen. Patients less than 3 months of age constitute 63% of the total patients seen. Normal echocardiographic examinations were found in 342 (55%) of patients. These patients were not seen in our cardiology clinic. Abnormal echocardiographic examinations were found in 281 (45%) of patients. Among the 281 patients with abnormal echos in the outreach visits, 251 patients (89.3%) were seen in the pediatric cardiology clinic. Comparing the results of the outreach clinic evaluation to that of the pediatric cardiology clinic, 73 patients (29%) diagnosed to have a minor CHD turned to have normal echocardiographic examinations. In all patients seen in both the outreach clinics and the pediatric tertiary cardiac clinics there was no change in patient's management plan. CONCLUSIONS: Outreach clinic conducted by pediatric echo sonographers could be useful and safe. It may help in reducing unnecessary visits to pediatric cardiology clinics, provide parental reassurance, and help in narrowing the differential diagnosis in critically ill patient unable to be transferred to tertiary cardiac centers provided it is done by experienced echosonographers.

Incidence of severe congenital heart disease at the province of Al-Qassim, Saudi Arabia.

UNLABELLED: Worldwide, congenital heart defects (CHD) are the leading cause of infant deaths owing to congenital anomalies. Knowing the actual incidence of severe CHD is important for defining the requirement for resources and the burden of disease within the total population. OBJECTIVES: The aim of the study is to estimate the incidence of severe CHD at the province of Al-Qassim as a reflection of that in the Kingdom of Saudi Arabia. STUDY DESIGN: A retrospective database review of all cases diagnosed to have severe CHD at Prince Sultan Cardiac Center-Qassim during a 3-year period from January 2008 to December 2010. RESULTS: During the study period, 316 patients were diagnosed to have severe CHD. During the 3-year study period, the total live birth at the province of Al-Qassim was 58,908. The incidence of severe CHD is 5.4/1000 live birth/year. Sixty-five percent of cases were diagnosed at less than 2 months of age, with a median age at diagnosis of 45 days (range of 1 day to 1 year). Ventricular septal defect was the most common lesion diagnosed (22.5%). Collectively, prostaglandin-dependent lesions constitute 38% of cases. Fifteen percent of patients were proved to have a syndrome. The most common syndrome was Down syndrome. CONCLUSION: . Severe CHD is a major health problem at the Kingdom of Saudi Arabia and worldwide. The incidence of severe CHD likely to require intervention in infancy, in the province of Al-Qassim, Saudi Arabia, is 5.4 per 1000 live births.

Waiting time for transfer of patients with prostaglandin dependant congenital heart defects to tertiary cardiac centers.

UNLABELLED: Worldwide congenital heart defects (CHD) are the leading cause of infant deaths owing to congenital anomalies. Delay in diagnosing and operating in neonates with prostaglandin dependant CHD may lead to significant morbidity and mortality. OBJECTIVES: To assess the time interval needed for acceptance and transfer of patients with critical CHD to a tertiary cardiac center and the impact on the patient's survival. STUDY DESIGN: Retrospective database reviews of all cases diagnosed to have prostaglandin dependant (PG) CHD at Prince Sultan Cardiac Center-Qassim during a 43 months period (from May 2007 to December 2010). RESULTS: During the study period 104 patients were diagnosed to have PG dependant CHD. Patients with PG dependant systemic circulation constitute 60% of patients. Patients with ventricular septal defect (VSD) associated with coarctation of the aorta constituted 16% of patients. The mean waiting time for transfer to a tertiary cardiac center was 10 ± 10 days. Twenty-two (21%) patients died while waiting for acceptance and transfer. Eleven patients were diagnosed with hypoplastic left heart syndrome (HLHS). There was no significant difference in the waiting time for those with or without HLHS, with a mean of 9 days for both. Six of our patients had infections with positive blood cultures. The mean waiting period for those with proved infection was 25 days compared with 8 days for those with no proved infection (p value < 0.005). CONCLUSION: There are a significant number of patients with severe CHD who die while waiting for acceptance and transfer to a tertiary cardiac center. The causes for delay could be the presence of infection, prematurity and low birth weight. The limited numbers of tertiary cardiac centers in Saudi Arabia as well as cardiac ICU beds are among the factors delaying the acceptance of patients requiring cardiac surgery.

Outcome of tracheostomy after pediatric cardiac surgery.

OBJECTIVE: To investigate the incidence, timing indications and outcome of tracheotomy in children who underwent cardiac surgeries. METHODS: All pediatric cardiac patients (under 14 years of age) who underwent cardiac surgeries and required tracheotomy from November 2000 to November 2010 were reviewed. The data were collected and reviewed retrospectively. RESULTS: Sixteen children underwent tracheotomy after cardiac surgery. Fifteen of these cases had surgery for congenital heart disease, and one had surgery for an acquired rheumatic mitral valve disease. The mean ± SEMs of the durations of ventilation before and after tracheotomy were 60.4 ± 9.8 and 14.5 ± 4.79 days respectively (P value 0.0002). The means ± SEM of the lengths of ICU stay before and after tracheotomy were 63.31 ± 10.15 and 22 ± 5.4 days respectively (P value 0.0012). After the tracheotomy 12/16 patients (75%) were weaned from their ventilators and 10/16 were discharged from the PCICU. Six patients were discharged from the hospital and 3 were successfully decannulated. The overall survival rate was 9/16 (56%). CONCLUSION: Tracheostomy shortens the duration of mechanical ventilation and facilitates discharge from the ICU. The mortality of tracheotomy patients is still significant but is mainly related to the primary cardiac disease.

Transcatheter closure of patent ductus arteriosus in infantile form of Scimitar syndrome with a type II Amplatzer Ductal Occluder.

We report a unique case of infantile form of Scimitar syndrome with a patent ductus arteriosus and pulmonary hypertension. The PDA was closed percutaneously using the new Amplatzer Ductal Occluder device type II.

Outcome of Norwood and Damus-Kaye-Stansel procedures for univentricular congenital heart anomalies.

OBJECTIVES: To review the experience with Norwood and Damus-Kaye-Stansel (DKS) staged repair in the management of hypoplastic left heart syndrome (HLHS), or functional single ventricle (FSV) with systemic outflow tract obstruction (SOTO). METHODS: A retrospective study was conducted from a single center from January 2001 to September 2007 at the Cardiac Sciences Department, King Abdulaziz Cardiac Center, National Guard Health Affairs, Riyadh, Kingdom of Saudi Arabia. The cardiac departmental database was reviewed, together with the echocardiographic findings. Demographic data representing age and weight at operation, gender, cardiac anatomy, non-cardiac abnormalities, and operative details were collected. RESULTS: Twenty-eight patients with a diagnosis of HLHS were included in the study. The mean +/- SD for weight was 3.4 +/- 0.85kg and 32 +/- 37 days for age. All infants at our institution who underwent a Norwood or DKS surgery for HLHS, or other forms of FSV with SOTO were included. All included patients underwent first stage palliation consisting of either a classical Norwood procedure in 6/23 (21%) patients, or a modified Norwood with right ventricle to pulmonary artery (RV-PA) conduit in 22/28 (79%) patients. After first stage palliation, 23 patients (82%) survived, and all but one underwent second stage palliation with bidirectional cavopulmonary anastomosis (BCPA). The survival rate after second stage repair was 91%. Subsequently, 4 patients completed a third stage Fontan with 100% survival. All deceased patients had HLHS. CONCLUSION: The Norwood procedure is applied to a heterogeneous group of patients with variable outcomes in certain subgroups. Patients with HLHS palliated with the Norwood procedure are at a greater risk for morbidity and mortality compared to those with other forms of FSV with SOTO.

Persistent fifth aortic arch diagnosed by echocardiography and confirmed by angiography: Case report and literature review.

Persistent fifth aortic arch is a rare congenital anomaly that can be discovered incidentally or at postmortem exam. It can be associated with major congenital heart malformations involving the systemic or the pulmonary circuits. It usually has no clinical significance but can be either, beneficial as in systemic outflow tract obstructions or cause hemodynamic compromise when associated with a significant left to right shunt. We report an infant with persistent fifth aortic arch associated with Shone's complex diagnosed accurately by transthoracic echocardiography and confirmed by cardiac catheterization and computed tomography.
