Objective: Tricuspid annular plane systolic excursion (TAPSE) is an echocardiographic measurement used for evaluating right ventricular systolic function. While established reference values of TAPSE exist for the adult population, only a limited number of studies have attempted to evaluate reference values for the pediatric population. The aim of the present study was to determine the reference values for TAPSE in healthy children in Turkey., Methods: A total of 765 healthy children aged between 0 and 18 years, all of whom were referred to our clinic with cardiac murmurs, were evaluated prospectively. Patients with no cardiac pathologies or other disorders were excluded from the study. The measurement of TAPSE was obtained using a 2D-guided M-mode technique with echocardiography, and the relationship between age and surface area with TAPSE was investigated. The statistical analysis was carried out using the SPSS 20.0 software package (SPSS Inc., Chicago, IL, USA, 2012)., Results: The mean TAPSE value was found to be 19.56±5.54 mm, and no significant difference was identified between male and female children. TAPSE values showed a positive correlation with increasing age and surface area. The mean TAPSE value was 9.09±1.36 mm in newborns and 25.91±3.60 mm in the 13-18 years age group. A negative correlation was seen between TAPSE and heart rate., Conclusion: In the present study, the reference values for TAPSE in healthy Turkish children were presented in percentile tables and the corresponding z-scores were determined. These reference values may be useful in daily practice for the evaluation of right ventricular systolic function in children.

Objective: Coarctation of the aorta (CoA) accounts for 3.5% of all congenital heart diseases in children. The clinical manifestations range from heart failure to asymptomatic hypertension. Treatment options include surgical repair, balloon angioplasty, and stenting. We aimed to investigate the long-term results of surgery and balloon angioplasty to identify the possible risk factors for recoarctation and predictors associated with early success in treatment modalities. Materials and Methods: The data of 138 children who underwent examinations at a tertiary center between 2015 and 2020 with the diagnosis of CoA were evaluated. The basic demographic characteristics, clinical and echocardiographic findings, results, and treatment methods of the patients were evaluated retrospectively. Results: The mean follow-up period was 75.1 months (range of 1-223). As initial treatment, 75 patients (60.5%) underwent balloon angioplasty, 44 (35.5%) underwent surgery, and 5 (4%) underwent stenting. The early success rate of balloon angioplasty and surgery was 72.5% and 79.5%, respectively. Recoarctation occurred in 47.6% of patients following the first therapy. The median reintervention-free survival time was 138 months for all patients and was significantly higher in the surgery group (P = .025). The recoarctation rate was slightly lower in the surgery group than in those who underwent balloon angioplasty, but it was not statistically significant. None of the clinical and echocardiographic findings were found to be associated with recoarctation or early success. Conclusion: The rate of recoarctation is still high in long-term follow-up after aortic coarctation treatment, and clinical and echocardiographic findings are insufficient to predict the chance of early success and the risk of recoarctation.

Objective: Ventricular extrasystole is one of the most common rhythm disorders in children, and almost all of them are characterized by normal cardiac functions without structural cardiac abnormalities. The aim of this study was to assess the clinical course of ventricular extrasystole in children who did not have cardiac structural abnormalities. Materials and Methods: This retrospective study analyzed 24-hour rhythm Holter recordings performed in our clinic in children. Patients diagnosed with isolated ventricular extrasystole in Holter records and without structural heart disease on echocardiography were included in the evaluation. Results: A total of 20 160 Holter results were evaluated in the study, and 226 patients (male; 66%) met the criteria. The mean follow-up time was 8.7 ± 3.2 years. While 81.8% of the patients were asymptomatic, the most common symptom was palpitation and 5 patients had syncope. Of the patients, 72 (31.8%) received medical therapy. Beta-blockers were the most often prescribed medication. Cardiomyopathy did not develop in any of the patients during the followup period. A partial reduction in the frequency of ventricular extrasystole was observed in 42% of the patients, while complete recovery was observed in 22%. Conclusion: Ventricular extrasystole in children generally has a good prognosis; most of them are asymptomatic, and the rates of spontaneous regression over time are quite high, regardless of the origin.

Objectives: Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology. Coronary artery lesions (CAL) develop in 15% to 20% of untreated cases. Our objective was to evaluate demographic, clinical, and laboratory features and short-intermediate coronary artery outcomes of children with KD. Patients and Methods: Medical records of patients with KD were retrospectively identified. Clinical information and echocardiography, laboratory, and angiographic results were noted using a standardized form. Results: The study included 44 patients with a mean age of the 29.72 ± 21 months (ranging from 1 month to 9.5 years). There were 28 male and 16 female patients; 20 patients were diagnosed as having had incomplete KD. Four cases with atypical presentation were significantly older than children with complete and incomplete KD; 17 patients (38.6 %) had coronary artery aneurysm (CAA), which declined to 6.8% after intravenous immunoglobulin (IVIG) treatment. Time between fever and diagnosis and abnormal levels of hemoglobin and platelets were all associated with CAA. The children were followed up for a mean of 36.39 ± 19 months (with a maximum of 16 years). Angiographic evolution and regression of CALs have been observed in 14 (82.3%) patients. Three patients in whom CALs persisted did not receive IVIG therapy because of delayed diagnosis. Conclusions: Awareness of KD in children has led to an increase in the number of cases. Utility of IVIG treatment to reduce the coronary artery involvement in patients with delayed diagnoses should be discussed and considered. Long-term results are required to assess whether the KD represents a risk factor for coronary artery diseases seen during adulthood. [ABSTRACT FROM AUTHOR]

Although congenital coronary artery anomalies are seen in 0.6-1 % of adult patients undergoing coronary angiography, the data for the pediatric population are few. This study of 22 children with coronary artery anomalies evaluated them in terms of demographic and clinical features and analyzed their angiographic findings and surgical results. Databases in the Department of Pediatric Cardiology at the University of Uludag were searched for all the patients with a diagnosis of congenital coronary artery anomaly who underwent coronary angiography between 1993 and 2013. Patients with coexistent congenital heart disease were excluded from the study. The study noted 22 patients (0.9 %; 10 boys and 11 girls) with coronary artery anomalies. The mean age of these patients was 58.77 ± 52.04 months (range, 1 month-16 years). Coronary arteriovenous fistula (50 %) and anomalous left coronary artery from the pulmonary artery (ALCAPA) (36 %) were the most common anomalies. In addition, the study included one patient with diffuse coronary artery hypoplasia, one patient with muscular bridge, and one patient with left main coronary artery originating from the right aortic sinus valsalva. Of the 11 patients who had coronary atrioventricular fistula, 7 were asymptomatic, whereas 75 % of the patients with ALCAPA syndrome were admitted because of heart failure. Although 13 patients had an exact diagnosis by echocardiography, 50 % of the patients with ALCAPA syndrome had their diagnosis determined by catheter angiography performed because of severe mitral regurgitation or dilated cardiomyopathy. The mortality rate for all the patients was found to be 18.1 %. Eight patients with coronary arteriovenous fistula have been followed up without surgery to the present. In contrast, seven patients with ALCAPA syndrome have undergone surgery, and three have died. Two of these patients died during the postoperative period, and the remaining patient died suddenly during the preoperative period at home. Isolated congenital coronary artery anomalies are very rare in the pediatric population. Although most congenital coronary artery anomalies are clinically silent, they may be associated with severe symptoms in children. Recognition of potentially serious anomalies such as ALCAPA syndrome is mandatory so that early surgical treatment can be prescribed. [ABSTRACT FROM AUTHOR]

Subvalvular aortic stenosis accounts for 1-2 % of all congenital heart disease and for 8-20 % of cases of left-ventricular outflow tract (LVOT) obstruction in children. Recurrence of subaortic stenosis (SAS) is not uncommon after surgical management. This study was performed to investigate the clinical and surgical outcomes and to estimate the predictability of recurrences of SAS. Seventy-nine patients age 3-21 years with SAS between 1994 and 2010 were reviewed. Fifty-one patients had discrete SAS, whereas the remaining 15 patients had fibromuscular ridge-type SAS. Mean follow-up time without surgery was 22 months (range of 1-94). Forty-one patients with a diagnosis of SAS underwent surgery. Recurrence rates were 22.7 % (15 patients), and these patients developed SAS at a mean of 4.7 years follow-up. We performed second surgical membrane resection in only 1 patient. The risk of recurrence of SAS was only linked to higher preoperative LVOT gradient. Twenty-three patients had no aortic regurgitation (AR) at preoperative echocardiography. Of these, 39.1 % had trivial, 8.7 % had mild, and 8.7 % had moderate AR after surgery; there was no significant AR. We conclude that surgical intervention was required most of the time in patients with SAS, and surgical outcomes was excellent even if there were associated cardiac defects. The risk of recurrences was higher, especially in patients with higher initial LVOT gradients, although a second surgery was rarely necessary in these patients. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 17-year-old boy was diagnosed with suspected accessory mitral valve (AMV) during the evaluation of a cardiac murmur with no other associated anomalies, aortic regurgitation (AR), and followed up for 8 years by serial transthoracic echocardiography.

The article presents a case study of a 17-year-old boy with atrial septal defect (ASD). It states that the patient was also found to have huge mobile thrombus after undergoing transthoracic echocardiography (TTE). It adds that the patient undergone protein C and S, homocystein, and antithrombin III measurement to distinguish an inherited thrombotic disposition.
