Echocardiographic measurements in infants of diabetic mothers and macrosomic infants of nondiabetic mothers.

AIM: To compare echocardiographic findings of infants of diabetic mothers (IDMs), macrosomic infants of nondiabetic mothers and healthy full term appropriate-for-gestational-age (AGA) infants. METHODS: Included in this study were 83 infants, admitted to our Neonatology Unit. Thirty-three IDMs, including both macrosomic and nonmacrosomic, comprised Group A, 25 macrosomic infants of nondiabetic mothers comprised group B, and 25 healthy full term AGA infants comprised group C. Echocardiographic measurements were performed in the first three days after birth and compared by using one-way ANOVA, Post Hoc Tukey HSD and Student's t tests. RESULTS: The left ventricular end-systolic/left ventricular end-diastolic diameter ratio of group A was significantly smaller than that of group C (P<0.05). The interventricular septum/posterior wall thickness ratios of groups A and B were greater than those of group C (P<0.05). The left ventricular mass index of group A was greater than those of groups B and C (P<0.05). The shortening fraction and ejection fraction of group A were increased in comparison to group C (P<0.05). When comparing the values of echocardiographic measurements of macrosomic IDMs (n=9) with nonmacrosomic ones (n=24), and infants of pregestational diabetic mothers (n=11) with those of gestational diabetes mothers (n=22), no statistical difference was found. CONCLUSION: The present study suggests that underlying mechanisms common to both macrosomic infants of nondiabetic mothers and IDMs lead to less cardiac alterations in the macrosomic infants of nondiabetic mothers than in IDMs.

The myocardial performance index in children with isolated left-to-right shunt lesions.

OBJECTIVE: The myocardial performance index (MPI) measures the ratio of isovolumic time intervals to ventricular ejection time. The effects of altered ventricular preload or afterload on MPI have yet to be determined. This study was designed to determine the impact of altered preload on left and right ventricular myocardial performance index in the clinical setting of left-to-right lesions. METHODS: The left and right ventricular myocardial performance indexes were measured in 17 patients with atrial septal defect (ages 6 to 148 months), 23 patients with ventricular septal defect (ages 2 to 160 months), and 24 healthy children (ages 3 to 160 months). A complete 2- dimensional and Doppler echocardiographic examination was performed in all study groups. RESULTS: In patients with atrial septal defect, ventricular septal defect, and control group subjects, the left ventricular MPI was 0.38, 0.37 and 0.32, respectively, and the right ventricular MPI was 0.24, 0.21, and 0.20, respectively. No significant differences in the left and right ventricular myocardial performance indexes were seen between patients with left-to-right shunt lesions and control subjects. CONCLUSION: This study documents that the myocardial performance index is a quantitative measure of ventricular function that appears to be relatively independent of changes in preload.

Cardiac troponin I elevation in paediatric cardiac catheterization.

OBJECTIVE: The aim of this study is to investigate prospectively whether intracardiac catheterization produces myocardial damage in paediatric heart. METHODS: The study was performed in all patients undergoing diagnostic cardiac catheterization at our institute. A baseline serum sample was drawn before the procedure. The second serum sample was obtained 4-6 hours after the procedure. Cardiac troponin-I and creatine kinase isoenzyme MB fraction levels were determined quantitatively. RESULTS: Diagnostic cardiac catheterization was performed in 30 patients. There were 17 males and 13 females in the study group. The median age was 12 months (range 1 to 204 months); the median body weight was 8 kilograms (range 2.1 to 45 kilograms). The increase in cardiac troponin I (0.21+/-0.04 ng/ml to 1.16+/-1.40 ng/ml, p<0.05) and creatine kinase isoenzyme MB (26.68+/-7.53 U/L to 41.65+/-22.12 U/L, p< 0.05) levels after the procedure was significant. CONCLUSION: This study shows that serum elevations of cardiac troponin I and creatine kinase isoenzyme MB occur after the most of paediatric diagnostic cardiac catheterization procedures.

PISA method for assessment of mitral regurgitation in children.

OBJECTIVE: The purpose of this study was to determine the feasibility and significance of the proximal isovelocity surface area (PISA) method in children with rheumatic mitral regurgitation (MR). METHODS: Thirty-one children (mean age 12.3+/-3.1 years), with chronic MR, were evaluated by semiquantitative and quantitative Doppler, quantitative two-dimensional echocardiography and the PISA methods. Also, we compared the effective regurgitant orifice area, regurgitation volume and systolic left ventricular functions in mild-moderate and severe MR. RESULTS: There were no statistically significant differences in the regurgitant orifice area and regurgitant volume values obtained by the PISA method and the quantitative Doppler (p>0.05) but they were different from the same values obtained by two dimensional echocardiography (p<0.05). There were excellent correlations between the regurgitant orifice area, regurgitant volume and the radius of the proximal flow convergence hemisphere (r=0.882, r=0.925, r=0.880; p<0.05). We found a very good correlation between the regurgitant orifice area obtained by the PISA and left ventricular end-diastolic diameters, the ratio of the jet/left atrial area, grading with color Doppler imaging (r=0.763, r=0.745, r=0.618; p<0.05). CONCLUSION: It is concluded that MR can be accurately predicted in children by using the PISA method as like as the Doppler method.

Cardiac troponin-I in the serum of infants of diabetic mothers.

A transient form of hypertrophic cardiomyopathy has been previously described in infants of diabetic mothers. When it occurs, it is generally benign. The purpose of our study was to establish the extent of injury to the cardiomyocytes in symptomatic and asymptomatic patients with and without hypertrophic cardiomyopathy. Thus, we compared 35 consecutive patients to 20 healthy controls, establishing the significance, if any, of differences in cardiac troponin-I and creatine kinase, including its MB-fraction, and seeking to establish the value of these parameters in the diagnosis of cardiac injury. We also determined to levels of glucose and insulin in the serum, and took note of electrocardiographic and echocardiographic investigations. Values were determined at the 1st and 7th days after admission in the patients, while parameters were measured in the control group only on the first day. We found that the levels of cardiac troponin-I in the serum, known to be a marker for cardiac injury, were significantly elevated in symptomatic patients with life-threatening respiratory or haemodynamic distress. We speculate that transient ventricular hypertrophy is neither the cause nor the consequence of damage to the cardiomyocytes. It would be interesting, nonetheless, to determine the relationship, if any, between cardiomyocytic damage and clinical outcome.

Criteria for judging the improvement in subclinical rheumatic valvitis.

Recent technical improvements in cross-sectional echocardiography have made it possible to detect even mild organic regurgitation of the mitral and aortic valves in patients with acute rheumatic fever. To determine the prevalence and prognosis of subclinical valvitis, we have analyzed 104 patients with acute rheumatic fever referred to our institution. Of 53 patients who had no murmur, 22 of them with polyarthritis, 29 with chorea, and 2 with polyarthritis and chorea, 23 (43.4%) had subclinical valvitis. Isolated mitral regurgitation was the most common valvar lesion, seen in 82.6% of the patients. Isolated aortic regurgitation was detected in 4.4% of the cases, and combined mitral and aortic regurgitation in the remaining 13%. During follow-up, the degree of mitral regurgitation improved in 59.1%, decreased in 18.2%, and increased or remained unchanged in 22.7% according to the length of colour jet. According to criterions of velocity, mitral regurgitation improved in 86.4% of the patients, and increased or unchanged in the remaining 13.6%. Mitral regurgitation disappeared completely in 6 of the patients (27.3%) as judged according to both the length of colour jet and the velocity of regurgitation. Aortic regurgitation improved in all the patients with this problem, disappearing completely in two of the four. Based on this experience, we suggest that not only the disappearance of regurgitation, but also improvements in the echocardiographic diagnostic criterions of regurgitation, such as the length of the colour jet less than 1 cm, or velocity less than 2.5 m/s, or indicative of regurgitation that is either intermittent or of short duration, should also be considered as criterions indicating improvement in valvar regurgitation in patients with subclinical rheumatic valvitis.

Pulmonary arterial pressure in children with croup syndrome.

PURPOSE: Croup syndrome or laryngotracheitis is one of the frequent causes of transient upper airway obstruction by laryngeal and tracheal blockage in infants and children. Upper airway obstruction may lead to increased pulmonary arterial pressure in children. In this study, the relationship between croup syndrome and pulmonary arterial pressure was investigated. MATERIALS AND METHODS: Forty children with croup syndrome and 14 healthy, age- and sex-matched control subjects were enrolled in this study. Of all patients, 12 with severe symptoms, such as dyspnea, cyanosis, hypoventilation, were accepted as "high croup score" (croup score >or=6). All patients with high croup score were treated with dexamethasone. We assessed pulmonary arterial pressure of patients during therapy using serial echocardiographic measurements. RESULTS: Our results showed that children with croup syndrome have significantly higher pulmonary arterial pressures than healthy subjects at the time of diagnosis. Pressure values of patients with high croup score were found to be significantly higher when compared with those of the low -core group (P < .05). However, there was no difference between 2 groups at the end of therapy. CONCLUSIONS: It is suggested that pulmonary arterial pressure increased to different extents in the acute stage of illness and that the degree of increase was related to the severity of disease and average hospital stay. In addition, increased pulmonary arterial pressure due to croup syndrome is reversible. Furthermore, evaluation of children with croup syndrome by using Doppler echocardiography may be useful in the monitoring of pulmonary arterial pressure and in the follow-up of their therapy.

Pulmonary arterial pressure in children with allergic rhinitis.

BACKGROUND: Chronic upper airway obstruction may lead to increased pulmonary arterial pressure in childhood. Allergic rhinitis is one of the frequent causes of upper airway obstruction by nasal blockage. The aims of the study were to evaluate the pulmonary arterial pressures in children with allergic rhinitis and the effect of topical corticosteroid therapy. METHODS: Forty-nine children composed of 27 subjects with seasonal and 22 subjects with perennial allergic rhinitis were enrolled in this study. The pulmonary arterial pressures were measured by using Doppler echocardiography. RESULTS: The pretreatment pulmonary arterial systolic, mean, and diastolic pressures of study group were significantly higher than in healthy controls (p < 0.05). The pulmonary arterial systolic and mean pressures of the patient group significantly decreased at the end of study (p < 0.05), whereas the decrease of the diastolic pressure was not statistically significant (p > 0.05) after the treatment of a topical corticosteroid, mometasone furoate (100 microg per day), for 8 weeks. CONCLUSION: Our results showed that children with allergic rhinitis have higher pulmonary arterial pressure levels compared with healthy controls and that increased pulmonary arterial pressure levels due to allergic rhinitis are reversible by using nasal topical corticosteroids. Further studies are needed to determine the clinical aspect of increased pulmonary arterial pressure.

Congenital aneurysm of the muscular interventricular septum in a child.

Congenital aneurysms of the muscular interventricular septum without ventricularseptal defect are extremely rare. We describe a five-month-old girl patient with congenital aneurysm, pathological ST changes and minimal right ventricular outflow tract obstruction. The electrocardiogram showed Wolf-Parkinson-White syndrome, pathological ST changes and combined ventricular hypertrophy criteria. The transthoracic echocardiography and cardiac catheterization demonstrated a septal aneurysm which was bulging into the right ventricle and systolic pressure gradients between the main pulmonary artery and right ventricle outflow tract with normal coronary arteries. The patient has shown no symptoms, but some rhythm disturbances may be expected because of her electrocardiographic anomalies. Therefore, these patients should be followed carefully because of possible complications.

Prevalence and distribution of children with congenital heart diseases in the central Anatolian region, Turkey.

Congenital heart diseases (CHD) are the most frequent malformation at birth. The aims of this study were to assess the prevalence of congenital heart disease, their different types, and the detection rate among children in the central Anatolian region in Turkey. The study was conducted during an eight-year period (March 1995-December 2002). The prevalence of CHD in a large tertiary care hospital in the central Anatolian region in Turkey was studied. The diagnosis of a structural defect was based on echocardiographic study. The following age groups were considered: neonates, infants and toddlers, preschool children, schoolchildren, and adolescents. In the study period, 1,693 children were found to have CHD; 1253 patients were neonates and infants. Total prevalence of CHD over the study period was 7.77 per 1000 live-born. The prevalence increased from 6.35 to 9.65 per 1000 live births between 1995 and 2002 (p < 0.05). The average age at diagnosis was 2.2 +/- 3.64 years (1 day to 18 years, median 5 months). There were 863 (51%) boys and 830 (49%) girls, with a male/female ratio of 1:1. Isolated ventricular septal defect (32.6%) was the most frequent acyanotic anomaly, and tetralogy of Fallot (5.8%) was the most frequent cyanotic anomaly. The commonest non-cardiac anomalies with CHD were musculoskeletal anomalies. Down syndrome was determined in 83 patients (78.3%) from all syndromic CHD cases. Congenital heart disease is a very significant health problem. It requires urgent measures in terms of organization of early diagnosis and proper management. The prevalence rate is comparable to that of similar developed countries. Increasing incidence of CHD might be attributed to more diagnoses with new technologic development or it may indicate a real increase in the defects.
