Tissue Doppler imaging (TDI) can detect myocardial dysfunction related to iron load in patients with beta-thalassemia major (TM). We aimed to assess the efficacy of pulsed-wave TDI (PW-TDI) in predicting myocardial iron load in patients with TM using T2* magnetic resonance (MR) as the gold-standard non-invasive diagnostic test. 33 asymptomatic TM patients, mean aged 18 +/- 6 years (6-31) with normal left ventricular (LV) global systolic function were evaluated by conventional echocardiography and PW-TDI. Results were compared with 20 age and sex-matched controls. TDI measures included myocardial systolic (Sm), early (Em) and late (Am) diastolic velocities at basal and middle segments of septal and lateral LV wall. Myocardial iron deposition were measured in 29/33 patients by T2* MR. TM patients were also subgrouped according to those with iron load (T2* 20 ms). Mean T2* was 12.3 +/- 7.8 ms (4-31.3). Abnormal myocardial iron load (T2* < 20 ms) was found in 25/29 (86%) patients. The following TDI measures were lower in patients than in controls: basal septal Em (P < 0.001) and Am (P < 0.05), mid-septal Am (P < 0.05), mid-lateral LV wall Sm (P < 0.05) and Am (P < 0.05). Regional myocardial dysfunction were more prominent in patients with T2*

Background: Ebstein's anomaly represents 40% of congenital tricuspid valve abnormalities. Studies about paediatric Ebstein's anomaly patients are limited., Aim: To evaluate clinical characteristics, treatment (medical/arrhythmia ablation/surgical) results, and outcome of Ebstein's anomaly patients, and to determine factors affecting arrhythmia presence and mortality., Methods: Clinical data, echocardiography, treatment results, and outcomes of patients followed in our centre between 2000 and 2017 were retrospectively evaluated., Results: A total of 79 patients (61 children, median diagnosis age: 1.5 years [1 day-24 years]) were included. Eight patients (10.1%) were deceased during the study period. Common associated anomalies were atrial septal defect/patent foramen ovale (56.9%), mitral regurgitation (25.3%), pulmonary stenosis/atresia (17.7%), and ventricular septal defect (16.5%). Genetic diseases/congenital anomalies were present in 5/3.8%. Tricuspid regurgitation was present in 75.9%, and severe in 50%. Arrhythmias were detected in 30.4%, and accessory pathway-mediated re-entrant tachycardia was the most common (67%). Wolff-Parkinson-White syndrome was present in 12.7%. Twenty-one ablation procedures (radiofrequency ablation [85.7%]/cryoablation [14.3%]) were performed in 16 patients (median age: 13.3 years [4.9-17]). Acute success/recurrence rates: 87.5/25%. Surgery was performed in 31.6% (median age: 6.5 years [4 days-29 years]), 7.6% were operated during the first month, and 12.6% during the first year. Second surgery was required in 28%. Perioperative mortality rate was 12%, and median mortality age was 25 days (1 day-17 years). Median follow-up period was 5.3 years (1 day-32 years). Older diagnosis age ( p = 0.005) and mild-moderate mitral regurgitation ( p = 0.036) were associated with arrhythmias. Younger age at diagnosis ( p = 0.012), younger age at first surgery ( p = 0.004), surgery before age three years ( p = 0.037), and presence of pulmonary atresia ( p = 0.000014) were associated with mortality. Gender, diagnosis age, congenital anomalies/genetic disorders, tricuspid regurgitation, arrhythmias, and surgery history did not have an independent effect on survival., Conclusions: In children and young adults presenting with Ebstein's anomaly, younger age at presentation and at surgery, surgery before age three years, pulmonary atresia were associated with death. Ablation procedures can be successfully performed but recurrence rate is still high.

Background: Gaucher disease is a rare lysosomal storage disorder caused by glucocerebrosidase enzyme deficiency resulting in the cumulative deposition of glucocerebroside in macrophages, predominantly effecting bone marrow, liver and spleen. Gaucher disease type IIIC is a rare subtype that is characterized by cardiovascular involvement, eye-movement disorders, and late-onset neurological symptoms., Case Presentation: We present a 14-year-old adolescent boy diagnosed with Gaucher disease type IIIC at age four with a homozygous D409H mutation who developed severe aortic valve stenosis, extensive aortic calcification and a porcelain aorta despite enzyme replacement treatment since the diagnosis. Despite the challenges during the cardiac surgery, we successfully performed transcatheter aortic valve implantation (TAVI). The patient developed a complete atrioventricular block and required a pacemaker after the TAVI. He experienced further complications during the follow-up., Conclusion: The case presents the challenges in the treatment of cardiovascular complications in patients with Gaucher disease and demonstrates the importance of individualized treatment approaches, as well as the potential advantages and complications of TAVI in difficult situations like this., Competing Interests: The authors declare that there is no conflict of interest.

Objective : To evaluate the oral health status and treatment needs of children with congenital and acquired heart disease. Methods : This descriptive study included 301 children aged 5-14 from June 2022 to June 2023. Heart conditions were classified by congenital/acquired status and severity. The children's sociodemographic characteristics, medical and dental history, tooth brushing habits, and non-nutritional habits (bruxism, nail-biting, thumb-sucking, etc.) were evaluated. Oral health assessments including caries, oral hygiene, enamel defects, and dental treatment needs-related indices were recorded. Results : The mean age was 8.95 ± 2.91 years, and 271 (90%) of the children had congenital heart disease. The children with moderate and severe heart disease had significantly higher decayed/missing/filled surfaces (dmfs) ( p = 0.038) and pulp exposure ( p = 0.015) compared to the children with mild heart disease. According to the International Caries Detection and Assessment System II (ICDAS II) index, which included initial caries lesions, there were no caries-free children and 75.7% had extensive caries. The mean plaque index and gingival index were found to be 1.18 ± 0.38 and 0.69 ± 0.53, respectively. Enamel defects were observed in 15.9%. The Treatment Needs Index (TNI) was 85.8% for the primary teeth and 88.9% for the permanent teeth. The Care Index (CI) was 12.4% for the primary teeth and 10.8% for the permanent teeth. Conclusions : Children with congenital and acquired heart disease exhibit a high prevalence of untreated dental caries, gingivitis, and plaque accumulation, with a high need for dental treatments. Dentists should prioritize addressing these issues to prevent the risk of infective endocarditis (IE) and improve oral health outcomes in this population.

Background: The safety of glucagon-like peptide-1 receptor agonists in pregnancy is under investigation. In this report, we want to share the results of a patient with polycystic ovary syndrome who applied to our outpatient clinic for diabetes and had two unplanned pregnancies following the initiation of exenatide for obesity treatment., Case Presentation: A 40-year-old woman with diabetes was admitted to the endocrinology outpatient clinic. On physical examination, the body mass index was over 35 kg/m ², therefore, exenatide treatment was started. Four weeks later, she came to suspicion of pregnancy, and obstetric ultrasound revealed a fetus at 17 weeks of gestation. Exenatide was interrupted. At 37 weeks of gestation, she gave birth to a female baby with atrial septal defect. The baby was followed with echocardiography annually until spontaneous closure of ASD when she was three years old. Two years later, the patient consulted us again for weight gain. Exenatide was prescribed again. After 5 months, an abdominal ultrasound revealed a fatty liver and detected a pregnancy compatible with 13 weeks of gestation. Two siblings are healthy now, 7 and 5 years old, respectively., Conclusion: This report contributes to our knowledge of fetal exposure to exenatide. Large-scale randomized studies are needed for its safe use in pregnancy., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Split/fracture and embolization of central venous/shunt catheters are rare but serious complications in children. Percutaneous retrieval of intravascular foreign bodies is an important minimal invasive treatment. This study is aimed to represent our largest pediatric sample experience till now of 17 years from a single institution. Another aim is to compare the results regarding the removal or leaving in place of embolized or ruptured intravascular or cardiac venous catheter parts in children., Patients and Methods: A total of 26 cases were included in this study. Any pediatric patient with normal coagulation parameters and a fractured catheter fragment was included in this study. Other intravascular foreign bodies related to interventional devices and/or pacemaker/implantable cardiac defibrillator leads were excluded from this study., Results: Twenty-six patients, of whom 25 had oncologic diseases and 1 had a ventriculoatrial shunt, were included. The median age was 83.5 months (between 20 mo and 18 y) at treatment.Superior vena cava (9 cases), followed by the right atrium (5 cases), were the most two common sites of embolization for cardiovascular foreign bodies. The success rate of percutaneous retrieval was 92.3% in all patients. There were neither complications nor deaths. The retrieval technique revealed a predisposition for extraction through the femoral vein (96.1%) and using snare techniques (100%). Additional catheters like pigtail, National Institutes of Health, or ablation catheters were used for stabilization in selective cases in which the permanent central venous fragments stuck to the vessels. A tractional maneuver and capturing the ruptured material in the middle were other trick points for successful retrieval. Patients were asymptomatic in 76.9% of cases (20/26)., Conclusion: Percutaneous retrieval of cardiovascular foreign bodies is a reasonable, safe, and effective way in children when the catheter fragments are free and mobile. It should be considered the preferred treatment option instead of surgery. In patients where catheter fragments are stuck and are adherent to vessels, it could be left, and followed up by anticoagulation. Novel techniques accompanied by an experienced team could be helpful in difficult cases., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Aim: To present the first-year experience of fetal cardiac interventions (FCIs) in a tertiary referral hospital and to evaluate the outcomes., Methods: This retrospective study consisted of four pregnant women who underwent fetal pulmonary or aortic balloon valvuloplasty between November 2020 and June 2021. The procedures were performed with a percutaneous cardiac puncture under the ultrasonography guidance. Gestational age at intervention, procedural success, complications, and perinatal outcomes were evaluated. Procedural complications defined as fetal bradyarrhythmia requiring treatment, pericardial effusion requiring drainage, balloon rupture, and fetal death. The procedure was considered technically successful if the valve was dilated with a balloon catheter. Ultimately successful procedure was defined as the discharge of infants alive with biventricular circulation., Results: A total of 5 FCIs attempted between 26 + 3 and 28 + 2 gestational weeks. While the procedure was technically successful in 2 cases with pulmonary stenosis, both attempts were unsuccessful in the fetus with pulmonary atresia. Although the procedure was technically successful in the patient with critical aortic stenosis, it ultimately failed. No fetal death occurred in our series and there were no procedure-related significant maternal complications. However, three interventions were complicated by fetal bradycardia and pericardial effusion necessitating treatment, and balloon rupture cropped up in one case., Conclusion: FCIs may lead to improving the likelihood of a biventricular outcome for selected fetuses. Careful selection of patients and centralization of experience are essential for obtaining favorable outcomes. Operators should be aware of procedural complications. Improved procedural techniques with a lower complication rate will be achieved through advanced medical technology and special balloon catheters., (© 2023 Japan Society of Obstetrics and Gynecology.)

Background: Primary cardiac tumors are extremely rare. Cardiac rhabdomyoma is the most common primary cardiac tumor. 50-80% of solitary rhabdomyomas and all multiple rhabdomyomas are associated with tuberous sclerosis complex. Due to spontaneous regression, surgery is necessary only in severe hemodynamic compromise and persistent arrhythmias. Everolimus, a mechanistic target of rapamycin (mTOR) inhibitor, can be used in the treatment of rhabdomyomas seen in tuberous sclerosis complex. We aimed to evaluate the clinical progression of rhabdomyomas followed-up in our center between the years 2014-2019 and evaluate the efficacy and safety of everolimus treatment on tumor regression., Methods: Clinical features, prenatal diagnosis, clinical findings, tuberous sclerosis complex presence, treatment and follow-up results were evaluated retrospectively., Results: Among 56 children with primary cardiac tumors, 47 were diagnosed as rhabdomyomas, 28/47 patients (59.6%) had prenatal diagnosis, 85.1% were diagnosed before one year of age and 42/47 patients (89.3%) were asymptomatic. Multiple rhabdomyomas were present in 51% and median diameter of tumors was 16mm (4.5 - 52 mm). In 29/47 patients (61.7%) no medical or surgical treatment were necessary while 34% of these had spontaneous regression. Surgery was necessary in 6/47 patients (12.7%). Everolimus was used in 14/47 patients (29.8%). Indications were seizures (2 patients) and cardiac dysfunction (12 patients). Regression in size of rhabdomyomas was achieved in 10/12 patients (83%). Although, in the long-term, the amount of tumor mass shrinkage was not significantly different between patients who received everolimus and untreated patients (p=0.139), the rate of mass reduction was 12.4 times higher in patients who received everolimus. Leukopenia was not detected in any of the patients, but, hyperlipidemia was noted in 3/14 patients (21.4%)., Conclusions: According to our results, everolimus accelerates tumor mass reduction, but not amount of mass regression in the long term. Everolimus may be considered for treatment of rhabdomyomas which cause hemodynamic compromise or life-threatening arrhythmias before surgical intervention.

Background: The increased survival of patients with congenital heart disease over the last three decades has been associated with improvements in diagnosis and treatment. This study aimed to evaluate therapeutic interventional catheterization, outcomes and complications of these procedures in neonates and premature infants., Methods: In this study, therapeutic catheterization procedures performed on neonates and premature infants with congenital heart disease at a university hospital between February 2000 and October 2019 were retrospectively evaluated., Results: A total of 322 procedures were performed on 279 neonates and 26 premature infants. Of the patients, 217 (67.4%) were male. The median age of the patients was 8 days (interquartile range [IQR] 2-20) and the median body weight was 3050 g (IQR 2900-3600). The most common procedures were balloon atrial septostomy, balloon aortic angioplasty, balloon pulmonary valvuloplasty and balloon aortic valvuloplasty (35.4%, 20.8%, 18.3% and 12.4% respectively). The most common diagnoses were transposition of the great arteries, coarctation of the aorta, pulmonary stenosis and aortic stenosis (26.7%, 19.3%, 15.2% and 11.5% respectively). Most procedures, 274 (85.1%), were successful. Complications were observed in 74 procedures (23%). Of these complications, 45 (14%) were minor and 29 (9%) were major. The most common complication was transient dysrhythmia (6.9%). There was no significant relationship between body weight, age and the rate of complications. However, longer procedure time and fluoroscopy time were associated with higher complication rates (p < 0.05). Four procedurerelated deaths were observed., Conclusion: Procedure-related complications are higher in the neonatal period. Although the complication rate varies according to the type of procedure, longer fluoroscopy time and procedure duration are associated with an increased complication rate. Procedures performed with the right indications, appropriate equipment and by experienced teams will play a key role in reducing complication rates.

Aim: The aim of our study was to evaluate the safety and efficiency of the 'figure-of-eight' suture among children and young adults with congenital heart defects who underwent interventional procedures, in patients with structurally normal hearts who underwent electrophysiological study and in haemodynamically impaired children and newborns. We also reported a novel femoral haemostasis method in patients with a central catheter by modifying the 'figure-of-eight' suture around the catheter for haemorrhage control., Method: Between 2015 and 2018, a total of 100 'figure-of-eight' sutures were performed in 90 patients (48 males, 42 females) where the median age was 12.5 years (minimum 3 days, maximum 22 years). The procedures were diagnostic angiography ( n  = 6), radiofrequency and/or cryoablation ( n  = 7) and interventional procedures ( n  = 87)., Result: Haemostasis was achieved in 89 of 90 patients. Haemostasis could not be achieved in one malnourished patient due to lack of subcutaneous tissue. There were no major complications. A bullous skin lesion and minor bleeding were the only complications seen in two patients. A central catheter was inserted in eight patients using the modified 'figure-of-eight' suture technique., Conclusion: The ' figure-of-eight' suture is a safe and effective method for femoral venous haemostasis in patients who require large sheaths for procedures, in those using high-dose heparin and in haemodynamically unstable children who need cardiac catheterisation.

Seckel syndrome is a very rare autosomal recessive disorder also known as bird headed dwarfism". It is characterised by proportional short stature, low birth weight, dysmorphic facial appearance, and mental retardation. In addition to its dysmorphic features, skeletal, endocrine, gastrointestinal, haematologic, genitourinary, and nervous system has been involved. Cardiovascular features very rarely associate with Seckel syndrome. We report two patients with Seckel syndrome, one with dilated cardiomyopathy and the other with multiple ventricular septal defects. Dilated cardiomyopathy and isolated ventricular septal defect have not been previously reported in Seckel syndrome. Cardiovascular evaluation should be performed in all patients with Seckel syndrome. Early diagnosis of congenital and acquired heart diseases will reduce morbidity and mortality in these patients.

Introduction: Accessory pathways are commonly seen due to delamination of tricuspid valve leaflets. In addition to accessory pathways, an enlarged right atrium due to tricuspid regurgitation and incisional scars creates substrates for atrial re-entries and ectopic tachycardia. We sought to describe our experience with catheter ablation in children with Ebstein's anomaly., Methods and Results: During the study period, of 89 patients diagnosed with Ebstein's anomaly, 26 (30.9%) of them who underwent 33 ablation procedures were included in the study. Accessory pathways were observed in the majority of procedures (n = 27), whereas atrial flutter was observed in five, atrioventricular nodal reentrant tachycardia in five, and atrial tachycardia in two procedures. Accessory pathways were commonly localised in the right posteroseptal (n = 10 patients), right posterolateral (n = 14 patients), septal (n = two patients), and left posteroseptal (n = one patient) areas. Multiple accessory pathways and coexistent arrhythmia were observed in six procedures. All ablation attempts related to the accessory pathways were successful, but recurrence was observed in five (19%) of the ablations. Ablation for atrial flutter was performed in five patients; two of them were ablated successfully. One of the atrial tachycardia cases was ablated successfully., Conclusions: Ablation in patients with Ebstein's anomaly is challenging, and due to nature of the disease, it is not a rare occasion in this group of patients. Ablation of accessory pathways has high success, but also relatively high recurrence rates, whereas ablation of atrial arrhythmias has lower success rates, especially in operated patients.

Background: Some elements were claimed to play a role in the pathogenesis of congenital heart defects (CHD) and influence the general well-being and health of these children., Objectives: We aimed to assess the levels of some elements simultaneously in the blood and teeth samples of children with cyanotic and acyanotic CHD compared with healthy children., Methods: A total of 39 children with CHD (11 with cyanotic and 28 with acyanotic CHD) and 42 age- and sex-adjusted controls were enrolled. Levels of 13 elements, including magnesium, phosphorus, calcium, chromium, manganese, iron, copper, zinc, strontium, cadmium, lead, mercury, and molybdenum, were assessed using inductively coupled plasma mass spectrometry., Results: Children with cyanotic and acyanotic CHD had significantly lower teeth calcium and calcium/phosphorus ratio as compared to the controls after adjusting for confounders. The mean blood iron level was found to be significantly higher in the cyanotic CHD group compared to the other groups. In addition, children with acyanotic CHD had significantly higher teeth copper levels, higher blood molybdenum and lower blood magnesium levels compared to the healthy control group. Blood cadmium and mercury levels were found to be significantly elevated in both the cyanotic and acyanotic CHD groups compared to the healthy control group. There were no differences in toxic metal levels of teeth in cases with CHD., Conclusion: Monitoring adequate and balanced gestational micronutrient intake might support not only maternal health but also fetal cardiac development and infant well-being. Supplementation of magnesium should be evaluated in patients having CHD., (Copyright © 2020 Elsevier GmbH. All rights reserved.)

Background: Lower respiratory tract infections caused by respiratory syncytial virus can be severe during infancy, which requires admission to the hospital. These infections may be more severe especially in patients with congenital heart disease. Passive immunisation with palivizumab, a monoclonal antibody, is recommended in high-risk infants. We tried to determine the compliance rates, factors affecting compliance, and also other microorganisms responsible for lower respiratory tract infections after palivizumab prophylaxis in these patients., Methods: We evaluated patients' compliance to prophylaxis with palivizumab in two consecutive respiratory syncytial virus seasons from pharmacy records. We also investigated factors affecting compliance and the frequency of hospitalisations for lower respiratory tract infections. We investigated the causative microorganisms detected in hospitalised patients., Results: In this study, 86.7% of the desired number of injections was achieved in 176 patients in two seasons. Out of these, 117 patients (66.4%) received all the doses they were prescribed. Although not statistically significant, compliance to prophylaxis was higher in male patients, cyanotic patients, those who started under 1 year old, and who lived in the city centre. Human metapneumovirus, parainfluenza type 3, and bocavirus were detected in the hospitalised patients., Conclusion: Patients with congenital heart disease can survive the period of infancy with less problem by making palivizumab prophylaxis more effective, and awareness about non- respiratory syncytial virus factors may be a guide for the development of new treatments.

Background: Macitentan is an orally active, potent, dual endothelin receptor antagonist and is the only registered treatment for pulmonary arterial hypertension that significantly reduced morbidity and mortality in a long-term study., Aim: We have recently reported that switch from bosentan to macitentan significantly improved exercise capacity in children and young adults with pulmonary arterial hypertension in a 24-week prospective study and well tolerated without adverse events. We now aimed to evaluate clinical efficacy, safety of switch in a larger patient population, in a 24-month prospective study., Methods: This is a single-institution, 24-month prospective study. Patients ≥12 years with idiopathic/heritable, pulmonary arterial hypertension, or related to CHD or residual pulmonary arterial hypertension due to repaired congenital systemic-to-pulmonary shunts and on bosentan treatment were included. Concomitant treatment with oral phosphodiesterase type 5 inhibitors/inhaled prostanoids was allowed. Outcome measures included change from baseline to 24 months, in the 6-minute walk distance, functional class, oxygen saturation at rest/after walk distance test, and natriuretic peptide levels. Safety end points included adverse events, laboratory abnormalities., Results: Twenty-seven patients (19 adults/8 children, mean age: 21.1 ± 6.3 years (12-36), weight: 53.1 ± 15.7 kgs (26-87)) were included. Mean duration of macitentan treatment: 22.3 ± 3.9 months (9-24). Six-minute walk distance significantly improved from baseline (mean: 458 ± 79 m (300-620)) at 6 months (mean: 501 ± 73 m (325-616) + 43 m) (p < 0.05), at 12 months (mean: 514 ± 82 m (330-626) + 56 m) (p < 0.05), and at 24 months (mean: 532 ± 85 m (330-682) + 74 m) (p < 0.05). We observed a significant improvement during the first 6 months but no incremental improvement after 6 months (p > 0.05). Macitentan did not significantly change functional class, oxygen saturation, and natriuretic levels (p > 0.05). None of the patients had anaemia, hepatotoxicity, and peripheral edema., Conclusions: Our study is the first study which showed that switch from bosentan to macitentan improved exercise capacity in children and young adults with pulmonary arterial hypertension significantly in the first 6 months and compared to baseline in 24 months and well tolerated without adverse events.

Objective: We aimed to evaluate congenital heart disease (CHD) cases according to EUROCAT subgroup classification that were diagnosed during the prenatal period in our center. Methods: CHDs that were prenatally diagnosed using ultrasonography and confirmed by fetal echocardiography were reviewed over a 10-year period. Subgroup classification was finalized at the post-partum period in terms of the EUROCAT guide 1.3. Congenital heart defect subtypes and obstetric outcomes (gestational week at delivery, birth weight, gender, extracardiac structural abnormalities, karyotype results if performed) were analyzed. Results: The data of 180 cases with CHD were examined. Left ventricular outflow tract obstruction (LVOT) was the most common CHD subtype (57/180; 31.6%), which included 48, five, and four cases of hypoplastic left heart syndrome (HLHS), coarctation of the aorta, and aortic valve atresia/stenosis, respectively. Eighteen pregnancies were terminated; the most common CHD subtype among patients of terminated pregnancies was hypoplastic left heart syndrome (HLHS) ( n  = 7, 38.8%). The most common extracardiac malformations were a single umbilical artery, esophageal atresia, and situs inversus in our study group. Eighteen of the 96 (18.75%) neonates with CHD died during the neonatal period. The most common CHD subtype was HLHS (7/18; 38%) among the newborns who died after birth. Conclusion: Prenatal diagnosis of a CHD and subgroup classification is very important for clinical decision making, including prenatal management, recommendations for termination of the pregnancy, postnatal management of the patient, and for early referral to pediatric cardiology and cardiovascular surgery centers.

Background This study aimed to determine cardiac findings in patients with mucopolysaccharidosis (MPS) and to assess the changes in these findings after enzyme replacement therapy (ERT). Methods A retrospective clinical cohort study was conducted on patients who were diagnosed with MPS between 1995 and 2018 in Hacettepe University, Division of Pediatric Metabolism. A total of 96 patients were diagnosed with MPS during the study period. Of these patients, 81 (84.3%) received ERT. Echocardiographic findings of the patients together with the 6-min walking test (6MWT) results before and after ERT were compared. Results Thirty-one participants (38.2%) were female, while 50 (61.8%) were male. The mean age of the participants was 11.97 ± 6.33 years (range: 1.8-30). Five patients (6.2%) had MPS type I, 14 (17.3%) had type II, 28 (34.6%) had type IVa, 33 (40.7%) had type VI and one (1.2%) had type VII. Before ERT, 69.4% of patients had mitral insufficiency (MI; mild: 40.5%, moderate: 16.5%, severe: 12.7%), 35.4% had aortic insufficiency (AI; mild: 22.8%, moderate: 12.7%) and 45.1% had tricuspid insufficiency (TI; mild: 39.2%, moderate: 2.5%). The median duration of the ERT was 3.5 years. The ERT significantly improved left ventricular hypertrophy (LVH), but all other study variables returned non-significant before and after treatment. ERT may improve LVH in MPS. Bearing in mind that MPS is a progressive disease, ERT seems to prevent significant deterioration of this ailment but is not able to reverse the already settled pathologies except for LVH. ERT is not able to reverse the damage, but provides stabilization; so it is best to initiate treatment before cardiac damage.

Background Autologous hematopoietic stem cell transplantation (AHSCT) remains the standard of care for younger patients with multiple myeloma (MM). Currently, high-dose melphalan (HDM) is recommended as conditioning regimen before AHSCT. Preclinical data suggest that combining bortezomib and melphalan has synergistic effect against multiple myeloma cells. Bortezomib and HDM (Bor-HDM) combination as conditioning regimen has been investigated by many other investigators. Objective In this retrospective study, we aimed to compare transplant-related toxicities and hematologic recovery of HDM and Bor-HDM conditioning regimens. Method We retrospectively evaluated hematologic recovery and toxicity profile in patients with MM who received AHSCT with either HDM ( n = 114) or Bor-HDM ( n = 53) conditioning regimen. Results Nonhematologic toxicities were comparable between HDM and Bor-HDM conditioning regimen, except mucositis and diarrhea being more frequent in the Bor-HDM group. Neutrophil and platelet engraftment time and duration of hospital stay were significantly shorter for HDM regimen. Conclusions In this retrospective analysis, we observed engraftment kinetics and duration of hospitalization were significantly worse in Bor-HDM conditioning regimen with manageable toxicities. Randomized studies are needed to further compare Bor- HDM regimen to HDM in terms of response rates, toxicities, and transplant-related mortality.

Background: Macitentan is an orally active, potent, dual endothelin receptor antagonist and is the only registered treatment for pulmonary arterial hypertension that significantly reduced morbidity and mortality in a long-term event-driven study. Aim Few studies compared the clinical efficacy and safety of switch from bosentan to macitentan only in adult patients with pulmonary arterial hypertension. We aimed to evaluate the clinical efficacy and safety of switch from bosentan to macitentan in children and young adults., Methods: This is a single-institution, 24-week prospective study. Patients ⩾12 years of age with idiopathic/heritable pulmonary arterial hypertension or related to CHD or residual pulmonary arterial hypertension due to repaired congenital systemic-to-pulmonary shunts and on bosentan therapy were included. Concomitant treatment with oral phosphodiesterase type 5 inhibitors and inhaled prostanoids was allowed. Outcome measures included change from baseline to week 24, in the 6-minute walk distance, functional class, oxygen saturation at rest/after 6-minute walk distance test, systolic pulmonary artery pressure estimated by echocardiography, and brain natriuretic peptide levels. Safety end points included adverse events laboratory abnormalities., Results: A total of 13 patients - 5 male and 8 female - completed the study. The mean age was 20.3±6.5 years (12-35) and weight was 54.0±14.5 kg (27-75). Five patients were ⩽18 years of age. Macitentan improved 6-minute walk distance from baseline (mean: 466±35 m (300-590)), at 12 weeks (mean: 494±78 m (325-590), +28 m) (p0.05). None of the patients had anaemia, hepatotoxicity, and peripheral oedema., Conclusions: Our study is the first study that showed that switch from bosentan to macitentan significantly improved exercise capacity in children and young adults with pulmonary arterial hypertension and is well tolerated without any adverse events.

Aypar E, Demirtaş D, Aykan HH, Kara-Eroğlu F, Düzova A. A girl with Henoch Schönlein purpura associated with acute rheumatic fever and review of literature. Turk J Pediatr 2018; 60: 576-580. Henoch Schönlein purpura (HSP) with acute rheumatic fever (ARF) is a rare entity and only few cases have been reported so far. In all previously reported cases with HSP and ARF, patients initially presented with purpuric rash, arthralgia/arthritis, or abdominal pain and later diagnosed as ARF. We report an 11-year-old girl with features of both ARF and HSP. She initially presented with arthralgia and murmur. Echocardiography showed mild to moderate mitral regurgitation. Later, the clinical course was complicated by purpuric rash and abdominal pain. She was treated conservatively with IM penicillin, acetylsalicylic acid and oral prednisolone. Our patient is the first patient with HSP and ARF who initially presented with features of ARF. A review of literature revealed a limited number of cases of HSP associated with ARF (14 cases including the present case); and that the response to treatment in cases suffering from ARF associated with HSP was good; but one should also be aware of serious cardiac complications in HSP patients which may be fatal.

Kumbasar U, Aypar E, Karagöz T, Demircin M, Doğan R. Pulmonary thromboendarterectomy in pediatric patients: Report of three cases. Turk J Pediatr 2018; 60: 604-607. Chronic thromboembolic pulmonary hypertension (CTEPH), which occurs due to impartial resolution of the pulmonary thrombus, is a rare type of pulmonary hypertension. However, most patients have an excellent long-term survival following pulmonary thromboendarterectomy (PTE). Pulmonary emboli and associated CTEPH is unusual in the pediatric population and is mostly reveals an underlying thrombophilic state. PTE is also recognized as the best therapeutic option in this subgroup of patients. In this case series, we report three young patients who had successfully undergone PTE due to pulmonary emboli and associated CTEPH.

The patent foramen ovale is almost a normal anatomical hole between the atria with ~30% incidence in the general population. It has been suggested that the patent foramen ovale is the cause of some neurological events, which is explained by paradoxical embolism. Transcatheter closure of the patent foramen ovale is a common procedure in adult patients with cerebral ischaemic events, but there are limited data investigating the results in children. Between January, 2005 and February, 2014, 17 patients' patent foramen ovales were closed by the transcatheter approach in our department. The indications for closure were transient ischaemic attack in 10 patients, stroke in four patients, and migraine in three patients. The mean age and mean weight at the time of the procedure were 11.1±3.7 years and 42.1±15.4 kg, respectively. We asked our patients whether their previous ailments continued. All patients responded to the study survey. In 15 patients, ailments did not continue after patent foramen ovale closure and they significantly decreased in two of them. We suggest that under the right conditions device closure of the patent foramen ovale is a safe solution for these cryptogenic ischaemic events and migraine.

Background: Despite concerns about complications with the implantable cardioverter defibrillator (ICD), it is effective for the prevention of sudden cardiac death (SCD). We aimed to analyze our midterm experience with ICD in children and young adults., Methods: This retrospective study included patients who were implanted with an ICD between 2001 and 2014. Demographic characteristics, clinical information, shock features, and complications for all patients with ICD were analyzed. The study population was divided into two groups: early-era patients implanted before 2008, and late-era patients implanted after 2008., Results: Sixty-nine patients (median age: 12 years, median follow-up: 52 months) were implanted with an ICD. Diagnostic categories were channelopathy (56.6%), cardiomyopathy (36.2%), congenital heart disease (5.8%), and other (1.4%). We performed implantation for primary prevention in 66.6% (39.3% in early-era patients and 85.4% in late-era patients). Thirty-one (44.9%) received 139 appropriate shocks (66% of total shocks) while 14 (20.2%) received 71 inappropriate shocks. However, there was no statistically significant difference in the use of appropriate shocks in the primary (66.7%) versus the secondary (72.2%) prevention groups. The incidence of appropriate and inappropriate shock was 66.7% and 33.3% in the primary prevention group, and 72.2% and 27.8% in the secondary prevention group, respectively. Two patients died, although only one death was the result of a lead problem., Conclusions: Although lead integrity problems, inappropriate shocks, and infections are significant issues, ICD therapy appears to be a safe, effective, and necessary option for the prevention of SCD in both children and young adults., (© 2016 Wiley Periodicals, Inc.)

Purpose: This study investigated postnatal cardiac anomalies determined by postnatal echocardiography in fetuses with the ascending aorta (AA) diameter larger than that of the main pulmonary artery (MPA) on the three-vessel view (3VV)., Methods: The study included 17 pregnancies. The diameters of the AA and MPA were assessed on the 3VV in second-trimester sonographic screening, and all the patients underwent postnatal echocardiography to assess the cardiac outcome., Results: In the study population, the mean AA diameter was 3.7 mm (range, 2.2-5.6 mm), and the mean MPA diameter was 3.2 mm (range, 1.8-5.2 mm). The mean AA/MPA ratio was 1.2 (range, 1.1-1.9). According to the postnatal echocardiograms, one of the patients had tetralogy of Fallot. This patient had the highest prenatal AA/MPA ratio (1.9). Among the remaining 16 cases, five had secundum atrial septal defects, with two having concomitant dilatation of the AA. There was one case of isolated dilatation of the AA., Conclusions: Although an AA with a diameter larger than that of the MPA on the 3VV does not usually indicate severe congenital heart disease involving the ventricular outflow tract and/or great arteries, careful prenatal and postnatal echocardiographic examinations are mandatory to determine the presence of congenital heart disease. © 2016 Wiley Periodicals, Inc.

Statins are known to display benefits in various diseases independently from their cholesterol lowering properties. In this study, we investigated the acute effects of atorvastatin on vascular reactivity to various spasmogens in isolated rat aorta. The responses to noradrenaline (NA, 10(-8) -10(-4) m), endothelin-1 (ET-1, 10(-10) -10(-7) m), and potassium chloride (KCl, 10-100 mm) were evaluated in aortic rings pretreated with atorvastatin (10(-7) -10(-4) m, 30 min). To verify the mechanism of action, the effects of atorvastatin were studied in the presence of cholesterol precursor, mevalonate (10(-2) m, 45 min), mevalonate-derived isoprenoids, namely geranylgeranyl pyrophosphate (GGPP, 5 × 10(-6) m, 30 min) and farnesyl pyrophosphate (FPP, 5 × 10(-6) m, 30 min), and in the absence of endothelium. In parallel, aortic rings were pretreated with the specific inhibitor of Rho kinase, Y-27632 (10(-7) -10(-6) m). Atorvastatin significantly and concentration-dependently reduced the contractions to spasmogens in rat aorta. This acute inhibitory effect was also evident in endothelium-denuded rings. Pretreatment with mevalonate and GGPP, but not with FPP, reversed the inhibitory effect of atorvastatin (10(-4) m) on NA and ET-1 induced contractions. Similar to atorvastatin, pretreatment with Y-27632 inhibited the contractions to NA and KCl in a concentration-dependent manner. Western blot analysis revealed that both atorvastatin (10(-4) m) and Y-27632 (10(-6) m) pretreatment inhibited the phosphorylation of myosin phosphatase target subunit-1 (MYPT-1) triggered by NA, indicating an inhibitory influence on myosin phosphatase. In conclusion, atorvastatin displayed an acute inhibitory effect on vascular contractility evoked by various spasmogens and the inhibitory effect was possibly mediated by the inhibition of mevalonate and GGPP synthesis as well as the prevention of MYPT-1 phosphorylation induced by Rho/Rho kinase., (© 2015 Société Française de Pharmacologie et de Thérapeutique.)

Acute promyelocytic leukemia (APL) has one of the most favorable prognoses among other leukemia subtypes. However, the major cause of mortality in APL is disseminated intravascular coagulation at the presentation. We present a case of acute myocardial infarction (MI) at the time of APL diagnosis before treatment. The patient suffered from chest pain, sweating and giddiness. He was hypoxic, hypotensive and bradycardic. ECG showed inferior MI. Unfractioned heparin infusion (850 U/h) was started and 5 min after the previous ECG showed total ST resolution. We suggest that in this case, MI was not related to atherosclerotic plaque rupture but related to DIC manifestation.

Ouabain is an endogenous Na(+)/K(+)-ATPase inhibitor whose chronic administration induces hypertension. Endogenous ouabain levels increase in human essential hypertension. On the other hand, Rho/Rho kinase (ROCK) pathway has been implicated in various animal models of hypertension. In the current work, we evaluated the possible involvement of Rho kinase in ouabain-induced hypertension. Ouabain was administered daily (20 µg/kg, i.p.) to Wistar rats for 6 weeks. After the ouabain treatment, we evaluated the possible changes in vascular responses to KCl and phenylephrine alone and in the presence of Rho kinase inhibitor Y27632. We also determined the expressions of ROCKs, Rho A and phosphorylation of myosin binding subunit of myosin light chain phosphatase (pMYPT) and activation of Rho A. Agonist-induced contractions in the presence of Y27632 are significantly decreased and Y27632-induced relaxations in aortas precontracted with phenylephrine are significantly enhanced with the chronic treatment of ouabain. Although the expressions of ROCK I and ROCK II remained unchanged, pMYPT expression was significantly increased in ouabain-treated group. Moreover, Rho A expression and activation were decreased after treatment with ouabain. Although Rho kinase expression did not change in aortas, increased basal Rho kinase activation may contribute to the development of ouabain-induced hypertension. Our current data present the first evidence that Rho kinase is involved in the development of ouabain-induced hypertension in rats.

Background: Previous studies have demonstrated structural changes in the heart and cardiac dysfunction in foetuses with intrauterine growth restriction. There are no available data that evaluated left ventricular dimensions and mass in neonates with symmetric and asymmetric intrauterine growth restriction. Therefore, we aimed to evaluate left ventricular dimensions, systolic functions, and mass in neonates with symmetric and asymmetric intrauterine growth restriction. We also assessed associated maternal risk factors, and compared results with healthy appropriate for gestational age neonates., Methods: In all, 62 asymmetric intrauterine growth restriction neonates, 39 symmetric intrauterine growth restriction neonates, and 50 healthy appropriate for gestational age neonates were evaluated by transthoracic echocardiography., Results: The asymmetric intrauterine growth restriction group had significantly lower left ventricular end-systolic and end-diastolic diameters and posterior wall diameter in systole and diastole than the control group. The symmetric intrauterine growth restriction group had significantly lower left ventricular end-diastolic diameter than the control group. All left ventricular dimensions were lower in the asymmetric intrauterine growth restriction neonates compared with symmetric intrauterine growth restriction neonates (p>0.05), but not statistically significant except left ventricular posterior wall diameter in diastole (3.08±0.83 mm versus 3.54 ±0.72 mm) (p<0.05). Both symmetric and asymmetric intrauterine growth restriction groups had significantly lower relative posterior wall thickness (0.54±0.19 versus 0.48±0.13 versus 0.8±0.12), left ventricular mass (9.8±4.3 g versus 8.9±3.4 g versus 22.2±5.7 g), and left ventricular mass index (63.6±29.1 g/m2 versus 54.5±24.4 g/m2 versus 109±28.8 g/m2) when compared with the control group., Conclusions: Our study has demonstrated that although neonates with both symmetric and asymmetric intrauterine growth restriction had lower left ventricular dimensions, relative posterior wall thickness, left ventricular mass, and mass index when compared with appropriate for gestational age neonates, left ventricular systolic functions were found to be preserved. In our study, low socio-economic level, short maternal stature, and low maternal weight were found to be risk factors to develop intrauterine growth restriction. To our knowledge, our study is the first to evaluate left ventricular dimensions, wall thicknesses, mass, and systolic functions in neonates with intrauterine growth restriction and compare results with respect to asymmetric or symmetric subgroups.

Objective: There is increasing evidence for an association between non-alcoholic fatty liver disease (NAFLD) and an increased risk of cardiovascular morbidity and mortality. The aim of this study was to investigate the association between aspartate aminotransferase-to-platelet ratio index (APRI) and carotid intima-media thickness (IMT) in obese adolescents with NAFLD., Methods: Seventy-six obese adolescents and 36 lean subjects were enrolled in this cross-sectional single-centre study. The obese subjects were divided into two subgroups based on the presence or absence of fatty liver with high transaminase levels (NAFLD group and non-NAFLD group). Fasting blood samples were assayed for transaminase, glucose, and insulin levels. Insulin resistance was calculated by the homeostasis model assessment (HOMA-IR)., Results: APRI values were higher in both obese groups (NAFLD and non-NAFLD) in comparison with the lean group. The NAFLD group had significantly higher APRI values than the non-NAFLD obese group and the lean group. Carotid IMT was higher in both obese groups (NAFLD and non-NAFLD) in comparison with the lean group. The NAFLD group had significantly higher measurements of carotid IMT than the non-NAFLD group and the lean group. APRI was positively correlated with most of the metabolic parameters (total cholesterol, low-density lipoprotein cholesterol, glucose, insulin, HOMA-IR) and with carotid IMT in the NAFLD obese group., Conclusions: This study demonstrated that a significant relationship exists between APRI and carotid IMT in obese adolescents with NAFLD. We suggest that an increased APRI score in obese adolescents with NAFLD can possibly serve to predict a more adverse cardiovascular risk profile.

Organic nitrates play an important role in the therapy of ischemic heart disease; however, their clinical application is limited by the development of vascular nitrate tolerance. We have previously shown attenuation of the cardioprotective effect of preconditioning in vascular nitrate tolerance. Here, we studied whether the development of vascular nitrate tolerance affects the infarct size, limiting effect of ischemic postconditioning (IPost) in the myocardium, and whether the activation of survival kinases plays a role in the molecular mechanism of postconditioning in the presence or absence of vascular nitrate tolerance. Male Wistar rats were treated with nitroglycerin/vehicle for 3 days to induce vascular nitrate tolerance. On the fourth day, isolated hearts were subjected to 30-minute coronary occlusion followed by 120-minute reperfusion with or without IPost. In nontolerant hearts, postconditioning significantly decreased infarct size as compared with ischemia/reperfusion; however, postconditioning failed to decrease infarct size in hearts of nitrate tolerant rats. Phosphorylation of ERK 1/2, Akt, or endothelial nitric oxide synthetase showed no significant differences between the groups at the 10th minute of reperfusion. Vascular nitrate tolerance interferes with the infarct size limiting effect of IPost. Activation of survival kinases is not crucial in the molecular mechanism of postconditioning, which remains unaffected in nitrate tolerance.

The aims of this study were to evaluate left ventricular (LV) systolic and diastolic function in obese adolescents with nonalcoholic fatty liver disease (NAFLD) using conventional echocardiography and pulsed-wave tissue Doppler imaging and to investigate the relations between LV function and carotid intima-media thickness (CIMT). LV remodeling, tissue Doppler-derived LV velocities, and cardiovascular risk profiles in obese adolescents with NAFLD were also studied. One hundred eighty obese adolescents and 68 healthy controls were enrolled in the study. LV end-diastolic and end-systolic and left atrial diameters and LV mass were higher in the 2 obese groups compared with controls. By pulsed-wave Doppler echocardiography and pulsed-wave tissue Doppler imaging, the NAFLD group had normal LV systolic function, impaired diastolic function, and altered global systolic and diastolic myocardial performance. In patients with NAFLD, LV mass was positively correlated with homeostasis model assessment of insulin resistance and serum alanine aminotransferase. CIMT was positively correlated with homeostasis model assessment of insulin resistance, alanine aminotransferase, and LV mass. By multiple stepwise regression analysis, alanine aminotransferase (β = 0.124, p = 0.026), homeostasis model assessment of insulin resistance (β = 0.243, p = 0.0001), LV mass (β = 0.874, p = 0.0001) were independent parameters associated with increased CIMT. In conclusion, insulin resistance has a significant independent impact on CIMT and LV remodeling in the absence of diabetes in patients with NAFLD. Pulsed-wave tissue Doppler imaging is suggested to detect LV dysfunction at an earlier stage in obese adolescents with NAFLD for careful monitoring of cardiovascular risk., (Copyright © 2013 Elsevier Inc.

No data are available on the relationship between subclinical hypothyroidism and risk factors for the development of cardiovascular disease in obese adolescents with nonalcoholic fatty liver disease (NAFLD). This study aimed to determine whether an association exists between subclinical hypothyroidism and risk factors for the development of cardiovascular disease in obese adolescents with NAFLD. The study enrolled 111 obese adolescents and 42 lean subjects. The obese subjects were divided into two subgroups based on the presence or absence of fatty liver with high transaminases: a NAFLD group and a non-NAFLD group. Subclinical hypothyroidism was defined as a thyroid-stimulating hormone (TSH) level higher than 4 mIU/l and a normal free-thyroxine level (0.6-1.8 ng/dl). Insulin resistance was calculated by the homeostasis model assessment (HOMA-IR). Left ventricular mass (LVM), LVM index measurements, carotid intima media thickness (IMT), and HOMA-IR values were higher in the NAFLD obese group with TSH levels higher than 4 mIU/l than in the NAFLD obese group with TSH levels lower than 4 mIU/l. Elevated TSH values in the NAFLD obese group were positively correlated with most of the metabolic and cardiovascular risk parameters such as total cholesterol (r = 0.606, p = 0.001), triglycerides (r = 0.476, p = 0.016), low-density lipoprotein cholesterol (r = 0.461, p = 0.004), insulin (r = 0.607, p = 0.001), HOMA-IR (r = 0.596, p = 0.002), carotid IMT (r = 0.894, p < 0.0001), and LVM (r = 0.563, p = 0.003). The findings demonstrated that the obese adolescents with NAFLD and subclinical hypothyroidism had a more adverse cardiovascular risk profile and a higher carotid IMT and LVM.

Background: Chest pain is a common presenting complaint to paediatrics, paediatric cardiology, and paediatric emergency departments. In this study, we prospectively evaluated clinical characteristics and causes of chest pain in children referred to our paediatric cardiology unit., Methods: A total of 380 children were included. Associated symptoms and past and family histories were evaluated. All patients underwent physical examination. The following studies were performed: complete blood count in all patients; fasting lipid profiles in overweight and obese children and children with a family history of premature cardiovascular disease; and electrocardiogram, chest X-ray, and echocardiogram in all patients. If necessary, 24-hour electrocardiogram monitoring or exercise stress tests were performed. Patients with a history of positive psychological findings were evaluated by a child psychiatrist., Results: The most common causes of chest pain were musculoskeletal disorders (37.1%), idiopathic chest pain (29.2%), and miscellaneous disorders, for example precordial catch syndrome (15%), respectively. Only 1 of 380 (0.3%) patients had chest pain due to a cardiac disorder. Electrocardiograms were abnormal in 4 of 380 (1.1%) patients. A total of 9 of 380 patients (2.3%) had dyslipidaemia., Conclusions: Although a paediatric cardiology referral may provide reassurance to the primary care and emergency department physicians, our results show that cardiac aetiologies for paediatric chest pain are very rare. We think that many patients in our study were adequately evaluated only by careful history, and physical examination. Therefore, we suggest that it may not be necessary to use echocardiogram in the routine evaluation of children with chest pain.

Chiari's network (CN) is an embryologic remnant of eustachian valve located in the right atrium (RA). Incomplete involution of the fetal sinus venosus valves results in ''redundant'' CN. CN has been found in 1.3-4 % of autopsy studies and is believed to be of little clinical consequence. However, a redundant CN may favor persistence of a patent foramen ovale, formation of an atrial septal aneurysm, atrial thrombus, or paradoxic embolism, or cause intense right-to-left shunting. It may also cause arrythmias or compromise cardiovascular functions. We report an asymptomatic newborn with a prominent CN prolapsing into the right ventricle and discuss the clinical consequences of a CN. Although the patient herein presented is asymptomatic, CN may cause persistent cyanosis in the newborns mimicking congenital heart disease. It can also be confused with other curvilinear, highly mobile pathologic structures in the RA, such as vegetation, flail tricuspid leaflet, ruptured chordae tendinae, thrombus, or tumor. CN is not always a benign structure; therefore, identification and accurate diagnosis by echocardiography is important.

Pierre-Robin sequence or syndrome (PRS) (OMIM #261800) is characterized by a small mandible (micrognathia), posterior displacement/retraction of the tongue (glossoptosis), and upper airway obstruction. It has an incidence varying from 1 in 8,500 to 1 in 30,000 births. Congenital heart defects (CHDs) occur in 20 % of the patients with PRS. Ventricular septal defect, patent ductus arteriosus, and atrial septal defects are the most common lesions. Noncompaction of the ventricular myocardium is a rare cardiomyopathy characterized by a pattern of prominent trabecular meshwork and deep intertrabecular recesses. It is thought to be caused by arrest of the normal endomyocardial morphogenesis. Isolated left ventricular noncompaction (LVNC) in patients with PRS has not been reported previously. This report describes a newborn with PRS and isolated LVNC. Previously, LVNC has been reported in association with mitochondrial disorders, Barth syndrome hypertrophic cardiomyopathy, zaspopathy, muscular dystrophy type 1, 1p36 deletion, Turner syndrome, Ohtahara syndrome, distal 5q deletion, mosaic trisomy 22, trisomy 13, DiGeorge syndrome, and 1q43 deletion with decreasing frequency. Karyotype analysis of the reported patient showed normal chromosomes (46, XX), and a fluorescent in situ hybridization study did not show chromosome 22q11.2 deletion. This is the first clinical report of a patient with isolated LVNC and PRS. Noncompaction of the ventricular myocardium is a rare and unique disorder with characteristic morphologic features that can be identified by echocardiography. Long-term follow-up evaluation for development of progressive LV dysfunction and cardiac arrhythmias is indicated for these patients.
