From cyanosis to diagnosis: A case report on right atrial fibroma in a pediatric patient.

A 3-year-old female patient presented with symptoms of cyanosis and intermittent eyelid edema, leading to the discovery of a lobulated mass in the right atrium, obstructing the superior vena cava. Despite the inability to entirely remove the mass due to its origins in the right atrium myocardium and its extension towards the sinoatrial node, successful surgical intervention and subsequent histopathological evaluation identified the mass as a fibroma, and postoperative symptoms were significantly alleviated.

Cerebellar metastasis of colon cancer at diagnosis: A very rare case.

Colorectal cancer (CRC) is one of the leading causes of cancer deaths worldwide. Besides, brain metastasis from CRC is relatively rare. A 68-year-old male referred to the emergency clinic with headache, vertigo, nausea, and vomiting. A cerebellar mass lesion was determined and totally excised. Pathology revealed a metastatic adenocarcinoma. Colonoscopic biopsy obtained from the lesion in the colon was reported as adenocarcinoma. A cerebellar recurrent lesion occurred, and radiotherapy was initiated. After radiotherapy, FOLFOX-bevacizumab combination regimen was initiated as the first-line treatment of the patient with metastatic colon cancer. Significant improvements in the clinical outcomes of CRC were achieved in recent years. However, brain metastasis from CRC has a poor prognosis. We aimed to report a rare presentation of CRC with synchronous brain metastasis.

Biruni Index as a Novel Diagnostic Tool for the Early Prediction of Mortality in Critical Patients With COVID-19: A Cohort Study.

BACKGROUND: The aim of this study was to find out the potential risk factors associated with mortality in severe coronavirus disease 2019 (COVID-19) patients hospitalized due to viral bronchopneumonia, and to establish a novel COVID-19 mortality index for daily use. METHODS: The study included 431 quantitative real-time polymerase chain reaction (qRT-PCR)-confirmed COVID-19-positive patients admitted to the intensive care unit in a tertiary care hospital. Patients were divided into training and validation cohorts at random (n= 285 and n= 130, respectively). Biruni Index was developed by multivariate logistic regression analysis for predicting COVID-19-related mortality. RESULTS: In univariate logistic regression analysis, age, systolic and diastolic blood pressures, respiratory and pulse rates per minute, D-dimer, pH, urea, ferritin, and lactate dehydrogenase levels at first admission were statistically significant factors for the prediction of mortality in the training cohort. By using multivariate logistic regression analysis, all of these statistically significant parameters were used to produce Biruni Index. Statistically significant differences in Biruni Index were observed between ex and non-ex groups in both training and validation cohorts (P < 0.001 for both comparisons). Areas under receiver operating characteristic (ROC) curve for Biruni Index were 0.901 (95CI%: 0.864-0.938, P < 0.001) and 0.860 (95CI%: 0.795-0.926, P < 0.001) in training and validation cohorts, respectively. CONCLUSION: As a pioneering clinical study, Biruni Index may be a useful diagnostic tool for clinicians to predict the mortality in critically ill patients with COVID-19 hospitalized due to severe viral bronchopneumonia. However, Biruni Index should be validated with larger series of multicenter prospective clinical studies.

Comprehensive Genetic Analysis of RASopathy in the Era of Next-Generation Sequencing and Definition of a Novel Likely Pathogenic >KRAS Variation.

Introduction: Germline pathogenic variations of the genes encoding the components of the Ras-MAPK pathway are found to be responsible for RASopathies, a clinically and genetically heterogeneous group of diseases. In this study, we aimed to present the results of patients genetically investigated for RASopathy-related mutations in our Genetic Diagnosis Center. Methods: The results of 51 unrelated probands with RASopathy and 4 affected relatives (31 male, 24 female; mean age: 9.327 ± 8.214) were included in this study. Mutation screening was performed on DNA samples from peripheral blood of the patients either by Sanger sequencing of PTPN11 hotspot regions (10/51 probands), or by a targeted amplicon next-generation sequencing panel (41/51 probands) covering the exonic regions of BRAF, CBL, HRAS, KRAS, LZTR1, MAP2K1, MAP2K2, NF1, NRAS, PTPN11, RAF1, RASA2, RIT1, SHOC2, SOS1, SOS2, SPRED1, and KAT6B genes. Results: Pathogenic/likely pathogenic variations found in 22 out of 51 probands (43.13%) and their 4 affected family members were located in PTPN11, BRAF, KRAS, NF1, RAF1, SOS1, and SHOC2 genes. The c.148A>C (p.Thr50Pro) variation in the KRAS gene was a novel variant detected in a sibling in our patient cohort. We found supportive evidence for the pathogenicity of the NF1 gene c.5606G>T (p.Gly1869Val) variation which we defined in an affected boy who inherited the mutation from his affected father. Conclusion: Although PTPN11 is the most frequently mutated gene in our patient cohort, as in most previous reports, different mutation distribution among the other genes studied motivates the use of a next-generation sequencing gene panel including the possible responsible genes.

Assessment of Cardiovascular Surgery Requirements in Children and Adolescents Admitted With Chest Pain To A Pediatric Emergency Clinic.

INTRODUCTION: Chest pain in children and adolescents is an important symptom in the pediatric emergency clinic. The aim of this study is to assess the characteristics of chest pain and cardiovascular surgery in the pediatric population. MATERIALS AND METHODS: There were 352 children who presented with chest pain to the pediatric emergency department between December 2007 and February 2017. These children were included in this study, which is a retrospective observational study. RESULTS: Among the 352 patients, six patients (1.7%) underwent cardiovascular surgery. Forty-eight patients (13.6%) were diagnosed with cardiac disease, and the most common cardiac causes were myocarditis and pericarditis. CONCLUSION: Only six patients (1.7%) who were admitted to the emergency department with chest pain needed cardiovascular surgery. The chest pain in children required less surgery, and mortality and morbidity were lower compared with adult cardiac chest pain.

Is there myocardial involvement in children with long-term follow-up for Kawasaki disease? A study based on two-dimensional speckle tracking echocardiography.

OBJECTIVE: This study aimed to determine the possibility of subclinical myocardial dysfunction detected by strain echocardiography in the late period of children with Kawasaki disease. MATERIAL AND METHODS: The study enrolled 30 patients with Kawasaki disease with a follow-up period of at least 12 months and 30 healthy age- and gender-matched children. During the follow-up period, standard echocardiography, pulsed and tissue Doppler, and strain echocardiography were recorded for both groups. RESULTS: The mean age at the time of the diagnosis was 2.6±2.3 years (2 months-11 years). The mean follow-up period after the diagnosis was 3.55±2.20 years. Conventional echocardiography, M mode, pulsed and tissue Doppler values, and myocard performance index did not reveal significant differences. Left ventricle strain and strain rate parameters obtained by apical four-, three-, and two-chamber views did not show statistical differences between patients and controls. There was a positive correlation between the duration of follow-up and global four- and three-chamber longitudinal strain and global longitudinal strain values (r=0.465, p=0.010; r=0.414, p=0.023; r=0.492, p=0.006, respectively), whereas global radial strain showed negative correlation (r=-0.517, p=0.003). CONCLUSION: The analysis of systolic strain and strain rate did not detect a subclinical myocardial dysfunction in the long-term follow-up of Kawasaki disease. However, strain values showed variability with the follow-up periods, which indicates that Kawasaki disease might cause left ventricular dysfunction in the later phases. Therefore, a follow-up of children with a diagnosis of Kawasaki disease is of capital importance.

Two Novel Pathogenic FBN1 Variations and Their Phenotypic Relationship of Marfan Syndrome.

Marfan syndrome is an autosomal dominant disease affecting connective tissue involving the ocular, skeletal systems with a prevalence of 1/5,000 to 1/10,000 cases. Especially cardiovascular system disorders (aortic root dilatation and enlargement of the pulmonary artery) may be life-threatening. We report here the genetic analysis results of three unrelated cases clinically diagnosed as Marfan syndrome. Deoxyribonucleic acid (DNA) was isolated from EDTA (ethylenediaminetetraacetic acid)-blood samples of the patients. A next-generation sequencing panel containing 15 genes including FBN1 was used to determine the underlying pathogenic variants of Marfan syndrome. Three different variations, NM_000138.4( FBN1 ):c.229G > A(p.Gly77Arg), NM_000138.4( FBN1 ):c.165-2A > G (novel), NM_000138.4( FBN1 ):c.399delC (p.Cys134ValfsTer8) (novel) were determined in our three cases referred with a prediagnosis of Marfan syndrome. Our study has confirmed the utility of molecular testing in Marfan syndrome to support clinical diagnosis. With an accurate diagnosis and genetic counseling for prognosis of patients and family testing, the prenatal diagnosis will be possible.

A Study of Mortality in Cardiac Patients in a Pediatric Intensive Care Unit.

OBJECTIVE: One of the major causes of mortality in the pediatric intensive care unit (PICU) is heart disease. This study aimed to determine the causes of mortality in children with pre-existing cardiac abnormalities who were admitted into the PICU. METHODS: Data were collected through patient profile assessment and outcome and heart diseases affecting prognosis were analyzed. Medical records of children were reviewed retrospectively. The updated Pediatric Index of Mortality 2 (PIM2) scores were used. Exploratory data analysis was performed using descriptive measures. Kolmogorov-Smirnov tests were used to test the normality of data distribution. RESULTS: Out of 566 admissions into PICU, 76 (13.4%) had cardiac abnormalities. Median and range of PICU stay were 5.50 and 417.88 days. The mean PIM2 score on admission was found to be 31.05. The most common admission was due to atrioventricular septal defect (AVSD) (15.7%), cardiomyopathy (13.1%), ventricular septal defect (VSD) (11.8%), tetralogy of Fallot (10.5%) and others (48.9%). There were multiple cardiac anomalies in 3.9% of patients. The most important cause of cardiac mortality in PICU was septic shock (26.0%) followed by cardiogenic shock (20.6%), and cardiac failure (13.7%). The nosocomial infection rate of cardiac patients in PICU was 10.5%. CONCLUSIONS: Our study reconfirmed that the PIM2 score is a good indicator of cardiac diseases. Infections, nosocomial infections, pneumonia, and septic shock were the leading causes of mortality in cardiac patients. Better infection control in the PICU may have a significant impact on decreasing mortality rates.

Comparison between different first-line therapy protocols in eradicating Helicobacter pylori in a region with high clarithromycin resistance.

INTRODUCTION: Helicobacter pylori infection is encountered in more than 50% of the world population. A high rate of clarithromycin resistance is observed among Helicobacter pylori strains in some regions because clarithromycin is a drug commonly used for the treatment of other infections. AIM: To identify an efficient eradication protocol for patients infected with H. pylori and to suggest an alternative first-line therapy particularly in countries with high clarithromycin resistance. MATERIAL AND METHODS: Patients (18-75 years old) having dyspeptic complaints in a 1-year period and diagnosed with H. pylori infection by gastric biopsy were included and randomised to three groups, each receiving different sequential eradication therapy (LAM-B: lansoprazole, amoxicillin, metronidazole, bismuth: LAM-T: lansoprazole, amoxicillin, metronidazole, tetracycline; LAM-BT: lansoprazole, amoxicillin, metronidazole, bismuth, tetracycline). Eradication was evaluated via urea breath test. RESULTS: This study included 166 patients (mean age: 40 ±12 years; female, 68.7%) with H. pylori infection. Among them, 50 (30.1%) were in the LAM-B group, 59 (35.5%) were in the LAM-T group, and 57 (34.3%) were in the LAM-BT group. The non-steroidal anti-inflammatory drug use was the lowest in the LAM-BT group. Eradication rates were over 80% and similar in each group, with the highest rate in the LAM-BT group (93%). Adverse event rate was the highest in the LAM-T group. Helicobacter pylori eradication was achieved in 143 (86.1%) patients. CONCLUSIONS: The combination regimens without clarithromycin achieved an eradication rate over 80% in all groups. Knowing and monitoring the regional antibiotic resistance rates is important for successful treatment of H. pylori infections.

Early Effects of Renal Replacement Therapy on Cardiovascular Comorbidity in Children With End-Stage Kidney Disease: Findings From the 4C-T Study.

BACKGROUND: The early impact of renal transplantation on subclinical cardiovascular measures in pediatric patients has not been widely investigated. This analysis is performed for pediatric patients participating in the prospective cardiovascular comorbidity in children with chronic kidney disease study and focuses on the early effects of renal replacement therapy (RRT) modality on cardiovascular comorbidity in patients receiving a preemptive transplant or started on dialysis. METHODS: We compared measures indicating subclinical cardiovascular organ damage (aortal pulse wave velocity, carotid intima media thickness, left ventricular mass index) and evaluated cardiovascular risk factors in 166 pediatric patients before and 6 to 18 months after start of RRT (n = 76 transplantation, n = 90 dialysis). RESULTS: RRT modality had a significant impact on the change in arterial structure and function: compared to dialysis treatment, transplantation was independently associated with decreases in pulse wave velocity (ß = -0.67; P < 0.001) and intima media thickness (ß = -0.40; P = 0.008). Independent of RRT modality, an increase in pulse wave velocity was associated with an increase in diastolic blood pressure (ß = 0.31; P < 0.001). Increasing intima media thickness was associated with a larger increase in body mass index (ß = 0.26; P = 0.003) and the use of antihypertensive agents after RRT (ß = 0.41; P = 0.007). Changes in left ventricular mass index were associated with changes in systolic blood pressure (ß = 1.47; P = 0.01). CONCLUSIONS: In comparison with initiating dialysis, preemptive transplantation prevented further deterioration of the subclinical vascular organ damage early after transplantation. Classic cardiovascular risk factors, such as hypertension and obesity are of major importance for the development of cardiovascular organ damage after renal transplantation.

Subclinical anthracycline-induced cardiotoxicity in long-term follow-up of asymptomatic childhood cancer survivors: Assessment by speckle tracking echocardiography.

OBJECTIVE: Survivors of childhood cancer treated with anthracyclines carry the risk for developing late-onset cardiotoxicity. The purpose of this study was to evaluate left ventricular (LV) function in this patient group and compare it with healthy controls by means of conventional and speckle tracking echocardiography (STE) after exposure to chemotherapy. MATERIAL AND METHODS: Conventional and STE were performed in 45 childhood cancer survivors (mean age 11 ± 4.6; 26 male) treated with anthracyclines (median cumulative dosage 240 mg/m2 ; range, 100-460) and compared with age, gender and body surface area matched healthy controls. Follow-up period after chemotherapy was 21.9 ± 17.8 months. Blood samples were taken from survivors and controls to determine brain natriuretic peptide (BNP). RESULTS: Following anthracycline exposure, pediatric cancer survivors had lower longitudinal, radial anteroseptal, and radial anterior strain values compared to controls (P < .05). The calculated global longitudinal and global radial strain values were lower compared to the control group (P < .05). Both groups had normal ejection fraction (EF) and fractional shortening (FS). Brain natriuretic peptide (BNP) levels of both groups were in the normal range. CONCLUSION: Despite normal EF and FS, children exposed to anthracycline therapy may have late-onset subtle changes of LV strain values measured by STE. Whether these changes of strain can predict future risk of developing heart failure needs to be explored in further studies.

Effect of high-dose oral cholecalciferol on cardiac mechanics in children with chronic kidney disease.

Cardiovascular factors are an important cause of mortality in chronic kidney disease, and vitamin-D deficiency is common in this patient population. Therefore, we aimed to investigate the effect of oral cholecalciferol on cardiac mechanics in children with chronic kidney disease. A total of 41 children with chronic kidney disease - the patient group - and 24 healthy subjects - the control group - free of any underlying cardiac or renal disease with low 25-hydroxyvitamin-D3 levels were evaluated by conventional tissue Doppler imaging and two-dimensional speckle-tracking echocardiography, both at baseline and following Stoss vitamin-D supplementation. Left ventricular strain and strain rate values were compared between the study groups. Initial longitudinal and radial strain as well as strain rate values of the left ventricle were significantly lower in patients. After vitamin-D supplementation, these improved significantly in patients, whereas no significant change was observed in the control group. Our study showed that, although conventional and tissue Doppler imaging methods could not determine any effect, two-dimensional speckle-tracking echocardiography revealed the favourable effects of high-dose cholecalciferol on cardiac mechanics, implying the importance of vitamin-D supplementation in children with chronic kidney disease.

A rare cause of early repolarisation in an adolescent boy with chest pain: myocardial bridging.

Early repolarisation is a common electrocardiographic (ECG) finding characterised by J-point and ST segment elevation ≥ 0.1 mV in two or more adjacent leads. The ECG pattern of early repolarisation is relatively common in asymptomatic subjects. Early repolarisation pattern may be seen in secondary conditions such as hypothermia, autonomic nervous system disturbances, cocaine abuse, hypercalcaemia and myocardial ischaemia. We present a case of an adolescent boy with chest pain and concurrent ST-segment elevation. Early repolarisation pattern was observed in the inferior leads of the ECG with increased troponin levels. He was shown to have myocardial bridging of the left anterior descending artery. The coronary anomaly was not associated with left ventricular hypertrophy. He was asymptomatic and the ECG changes normalised on the third day after admission. The patient was restricted from strenuous exertion and metoprolol was prescribed for prophylaxis.

Left ventricular mechanics are affected in children with celiac disease: A study based on two-dimensional speckle tracking echocardiography.

BACKGROUND: An association between cardiomyopathy and celiac disease has been reported, but not frequently. We examined the effects on cardiac mechanics in children with celiac disease (CD) by two-dimensional speckle tracking echocardiography (2DSTE). METHODS: Eighty-one children with CD were compared with a control group comprising 51 healthy children by echocardiographic examination. Children with CD who had been on gluten-free diet for more than 6 months were divided into two different groups: group 1 was positive for serum antitissue transglutaminase antibody (n=48), and group 2 was negative for serum antitissue transglutaminase antibody (n=33). Cardiac functions were evaluated in all children using conventional echocardiography, tissue Doppler imaging (TDI), and 2DSTE methods. RESULTS: For children with CD, the mean age and male:female ratio were 10.1±4.0 years and 26/55 (67% female), respectively, which did not differ from the controls. Patients were diagnosed at a mean age of 7.9±4.1 years, and the mean follow-up time was 2.37±2.98 years. Conventional echocardiography and TDI measurements did not differ between groups. The left ventricular longitudinal and radial strains, and strain rate values were significantly lower in patients with CD, particularly in those with positive antitissue transglutaminase antibody compared with the control group. CONCLUSIONS: Our results suggest that 2DSTE is superior to conventional and TDI echocardiography for evaluating subclinical carditis in children with CD.

The Role of M30 in Predicting the Severity of Liver Fibrosis and Inflammation in Chronic Hepatitis B Patients.

BACKGROUND: Liver biopsy is an invasive procedure that is currently still necessary for predicting underlying hepatic injury related to chronic viral hepatitis B (CVHB). To date, none of the studied non-invasive methods have been able to replace liver biopsy. An apoptotic serum marker, M30, which has been reported to indicate ongoing liver fibrosis, has been popular in recent years. OBJECTIVES: We aimed to investigate the possible role of M30 in predicting CVHB-associated hepatic injury and its severity. METHODS: Forty-eight patients undergoing liver biopsy for evaluation of the severity of CVHB-related liver injury and 40 healthy controls were included in this cross-sectional study. M30 levels were determined for all CVHB patients and controls, and other laboratory parameters and demographic features were obtained from our hospital's database. RESULTS: The mean ages of patients and controls were 39.7 and 45.7 years, respectively, and 35% of the controls and 52% of the patients were male. In contrast to lower platelet counts, transaminase and M30 levels were both higher in the patient group than in the controls. Among the investigated parameters, only transaminase increased as the fibrosis stage changed from mild to moderate; however, none of the laboratory parameters, including M30, differed as the histological activity index (HAI) score increased. CONCLUSIONS: M30 levels were higher in CVHB patients compared to healthy controls. However, M30 levels were similar in the mild and moderate stages of fibrosis, so they did not indicate the severity of underlying fibrotic or inflammatory processes in CVHB patients.

Cardiovascular functional and structural changes in children with primary hypertension.

BACKGROUND: Primary hypertension in children is not a benign condition because of end-organ damage. Early investigations of cardiovascular effects rely on vascular structural and functional changes. We aimed to determine presence of early cardiovascular involvement in children with primary hypertension. For this purposes, we investigated functional and morphological changes in vascular system. METHODS: Seventy-five consecutive patients with primary hypertension and 35 healthy children comparable for age and gender were studied. Patients were classified according to the stages of blood pressure. Intima-media thickness of the carotid arteries (cIMT), carotid-femoral pulse wave velocity (PWVcf) and Pulse Wave Augmentation Index (AIx) and Left Ventricular Mass Index (LVMi) were investigated. RESULTS: PWVcf and AIx were higher in patients (5.87±0.87 m/s vs. 5.29±0.67 m/s, P=0.02; 9.41±8.54% vs. 8.36±3.59%, P=0.04, respectively) than in controls. cIMT was evaluated significantly higher in study group than controls (0.46±0.06 mm vs. 0.35±0.12 mm, respectively, P=0.01). The mean LVMi was higher in patients (32.9±11.5 vs. 28.8±1.55, P=0.01). CONCLUSION: Our results demonstrated that vascular findings were more sensitive for target organ changes than the more frequently utilized LVMi in patients with pre-hypertension.

Will a second biopsy sample affect treatment decisions in patients with chronic hepatitis B?

BACKGROUND AND AIM: Liver biopsy is the gold standard for assessment of fibrosis in patients with hepatitis B. However, it has some disadvantages, including inter-observer and intra-observer variability in biopsy interpretation and specimen variation. A standard biopsy specimen represents only about 0.0002 % of the whole liver. It has been shown that two biopsy samples collected during a procedure have significant influence on the diagnostic performance of interpretation in patients with hepatitis C or non-alcoholic steatohepatitis. Therefore, we aimed to assess the influence of collecting two liver biopsy samples during a single procedure for staging and grading chronic hepatitis B. PATIENTS AND METHODS: 27 patients were included in the study. The median age of the patients was 43.51 ± 11.69. Fifteen patients were female, 12 patients were male. In the biopsy procedure, two samples of liver lobes were obtained. Grade and stage scores were compared between the two samples. Fibrosis staging and grading were assessed according to the Ishak scoring system. RESULTS: Numbers of portal tract and biopsy size were equal in the two samples. There was a significant difference between the samples in terms of histological activity index (p value = 0.04). However, the difference was not enough to distinguish the mild and moderate stages. On the other hand, no significant difference in fibrosis staging between the two samples was found. CONCLUSIONS: With this relatively small size of patients, in this study, we showed that a proper liver biopsy size is sufficient to predict treatment decisions in chronic hepatitis B patients. However, further studies are needed to show the association of sampling variability in patients with hepatitis B.

Effect of cholecalciferol on local arterial stiffness and endothelial dysfunction in children with chronic kidney disease.

BACKGROUND: As cardiovascular factors are the leading cause of mortality in chronic kidney disease (CKD) and as vitamin D deficiency is prevalent in this population, we aimed to examine the effect of oral cholecalciferol on cardiac parameters and biomarkers for endothelial cell activation in children with CKD. METHODS: Forty-one children with CKD and 24 healthy subjects free of any underlying cardiac or renal disease with low 25-hydroxyvitamin D3 (25OHD) levels were evaluated using echocardiography basally and following Stoss vitamin D supplementation. The local vascular stiffness and endothelial dysfunction markers were compared among the groups. RESULTS: Initial flow-mediated dilatation (FMD) measurements were lower and local arterial stiffness was significantly higher in patients. After vitamin D supplementation, these improved significantly in patients, while no significant change was observed for the healthy group. Homocysteine showed inverse correlation with baseline vitamin D level in CKD children and von Willebrand factor emerged as an independent risk factor for FMD impairment. CONCLUSIONS: Our interventional study revealed the favorable effects of high-dose cholecalciferol on cardiovascular and endothelial parameters, implying the importance of vitamin D supplementation in children with CKD.

Early signs that predict later haemodynamically significant patent ductus arteriosus.

OBJECTIVE: Our aim was to determine the optimal cut-off values, sensitivity, specificity, and diagnostic power of 12 echocardiographic parameters on the second day of life to predict subsequent ductal patency. METHODS: We evaluated preterm infants, born at ⩽32 weeks of gestation, starting on their second day of life, and they were evaluated every other day until ductal closure or until there were clinical signs of re-opening. We measured transductal diameter; pulmonary arterial diastolic flow; retrograde aortic diastolic flow; pulsatility index of the left pulmonary artery and descending aorta; left atrium and ventricle/aortic root ratio; left ventricular output; left ventricular flow velocity time integral; mitral early/late diastolic flow; and superior caval vein diameter and flow as well as performed receiver operating curve analysis. RESULTS: Transductal diameter (>1.5 mm); pulmonary arterial diastolic flow (>25.6 cm/second); presence of retrograde aortic diastolic flow; ductal diameter by body weight (>1.07 mm/kg); left pulmonary arterial pulsatility index (⩽0.71); and left ventricle to aortic root ratio (>2.2) displayed high sensitivity and specificity (p0.9). Parameters with moderate sensitivity and specificity were as follows: left atrial to aortic root ratio; left ventricular output; left ventricular flow velocity time integral; and mitral early/late diastolic flow ratio (p0.05) had low diagnostic value. CONCLUSION: Left pulmonary arterial pulsatility index, left ventricle/aortic root ratio, and ductal diameter by body weight are useful adjuncts offering a broader outlook for predicting ductal patency.
