Mayer-Rokitansky-Küster-Hauser syndrome associated with pulmonary stenosis.

Two siblings with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome associated with pulmonary valvular stenosis are reported. Although the syndrome is well documented, the genetic background and familial occurrence is not known and the association with cardiac anomalies has not previously been reported. This report is the first report which describes the combination of cardiac anomaly with MRKH syndrome.

Brucella endocarditis: case report and review of the literature.

Cardiac involvement in childhood brucellosis is rare and, when present, findings are usually seen in acute rheumatic fever with endocarditis. We report a successfully treated case of Brucella endocarditis in which the aortic valve was affected. Medical therapy did not cure this patient who, due to hemodynamic deterioration, required valve replacement. This case report suggests that successful management of Brucella endocarditis requires a combination of medical and early surgical therapy.

Evaluation of dysrhythmia in children with muscular dystrophy.

Myocardial involvement and dysrhythmia are common findings with muscular dystrophy and are among the leading causes of death. The authors evaluated rhythm and conduction abnormalities in children with muscular dystrophy by electrocardiography, signal-averaged electrocardiography, and Holter monitoring. Twenty-nine patients (mean age, 8 years) and 29 healthy control subjects were included in the study. Sixty-two percent of patients had electrocardiographic abnormalities defined as deep Q waves in V6, tall R waves in V1, and QRS axis deviation. The cardiomyopathy index was significantly greater in the patient group whereas QT and QTc dispersion values showed no significant difference. Holter monitoring revealed premature atrial and ventricular contractions more frequently than normal. However all were classified as Lown I and II. Mean heart rate was significantly higher in the patient group. The electrocardiograms of 41% of the patients showed late potentials. No relationship with these changes and cardiac function was observed. During the study, one patient died whose cardiomyopathy index was longer and had late potentials detected with signal-averaged electrocardiography. In conclusion, standard electrocardiography, cardiomyopathy index, signal-averaged electrocardiography, and Holter monitoring are valuable and reliable monitoring methods in children with muscular dystrophy.

Cardiac side effects of long-acting beta-2 agonist salmeterol in asthmatic children.

BACKGROUND: Salmeterol is a new long-acting beta 2 selective adrenoreceptor agonist. There are some reports about the cardiac side-effects of salmeterol in asthmatic adults. The aim of this study was to determine the cardiac side effects of salmeterol in children. METHODS: Seventeen children with moderate asthma (aged between 6 and 13 years, mean 8.76 years) received salmeterol with a spacer device (Volumatic 200 micrograms daily, b.i.d.) for 3 weeks. All the children were evaluated by 24 h ambulatory electrocardiography monitoring and echocardiography before, on the second and on the 21st day of treatment. RESULTS: In minimum heart rate measurements, there were significant differences between the baseline (mean +/- SD 54.29 +/- 7.13), second (59.24 +/- 6.86) and 21st day (60.65 +/- 8.23) results. Also, the mean heart rate before the treatment (89.59 +/- 6.78) was significantly different from that on the second (94.76 +/- 6.51) and 21st day (92.65 +/- 8.90) of treatment. Although all the values were within normal limits and there were no significant differences between the control group's values, a trend of increase in mean and the minimum heart rates was seen. There were no significant differences in blood pressure, serum K+, maximum heart rate, supraventricular and ventricular ectopic beats, ejection fraction, stroke volume, cardiac output and corrected QT interval at any time. No complaints of tremors or palpitations were reported. CONCLUSIONS: As no cardiac side effects were detected, it could be concluded that salmeterol is quite a safe drug for use in childhood asthma treatment.

Hydatid disease and massive cardiac involvement.

Cardiac hydatid cysts are rare and represent 0.5-2% of all cases. Cardiac localization of hydatid cysts usually occurs in adults. Diagnosis is difficult because of the long latency between infection and manifestation of the disease, and also symptoms are nonspecific. We present a case study of 13-year-old girl with lots of hydatid cysts localized in the neighbourhood of the inferior vena cava right atrium and the superior vena cava right pulmonary artery aorta and posterior portion of the left atrium and the left ventricle, and the intramyocardium of the posterior wall of the left ventricle. An abdominal computed tomography scan showed a solitary cyst in the right posterior lobe of the liver. Following albendazole therapy for 3 weeks, she was operated on without cardiopulmonary bypass. Numerous alive and dead cysts were removed. Hepatic cysts were drained by percutaneous ultrasonography guided aspiration technique after surgery. On the 8th postoperative day, she was discharged while she was still on albendazole therapy.

Unusual variation of asplenia syndrome.

The case of a 1-year-old cyanotic boy diagnosed with asplenia syndrome has been reported. By physical and laboratory examinations, levocardia, atrial inversion, primum ASD, single atrioventricular valve, single ventricle (left-hand morphology), rudimentary right ventricle (anterior, left-sided), pulmonary stenosis, left-sided vena cava, single vena cava superior were established and the case was diagnosed with asplenia syndrome. The patient has concordance between tracheo-bronchial situs and lung anatomy and inverted atrial and visceral situs, but without atrial isomerism that makes his case an unusual variation of asplenia syndrome.

Keutel syndrome: a report of four cases.

We report four new cases of Keutel syndrome. Clinical manifestation included abnormal cartilage ossification, multiple peripheral pulmonary stenosis (PPS), brachytelephalangism, subnormal IQ, repeated respiratory infections, otitis media and hearing loss. All four children have a typical facial appearance and are of consanguineous parents. Father and the fifth offspring exhibit a normal phenotype; the mother has pulmonary stenosis. This observation confirms Keutel syndrome as a distinct autosomal recessive syndrome.

Possible relationship between pulmonary hypertension and prostaglandins.

This study was performed on 20 children with congenital heart defect and left-to-right shunt. These patients were divided into two groups. Group I consisted of 10 patients with normal pulmonary arterial pressure while group II consisted of 10 patients with pulmonary hypertension. Prostaglandin Like Materials (PLMs) in pulmonary venous and arterial blood which were taken during cardiac catheterization were extracted and biologically assayed for Prostaglandin-Like Activities (PGLA) on rat stomach fundus. In all patients of group I, the ratio of pulmonary venous to pulmonary arterial PGLA levels (PV/PA-PGLA) was found to be less than one. However in group II, this ratio was less than one in only two patients. In 8 out of the patients in group II, the ratio was either 1 or greater. These data confirmed the early concepts suggesting the role of prostaglandins (PG) in regulating normal pulmonary circulation. In addition these data have suggested that PGs may have an important role in the development of pulmonary hypertension in some cardiac patients.

Congenital right coronary artery-right atrial fistula.

A rare type of congenital fistula between the right coronary artery and the right atrium, where fistula was draining just above the inferior vena caval orifice, is presented. Patient was operated on utilizing cardiopulmonary bypass and the fistulous opening into the right atrium was closed by interrupted ti-cron sutures supported with teflon pledgets. The benefits of using cardiopulmonary bypass in these operations or at least having it stand-by in the operating room are emphasized for safer closure of the fistula when needed.

Chest pain in children referred to a cardiology clinic.

One hundred consecutive patients (54 girls, 46 boys) referred to a pediatric cardiology department with the primary complaint of chest pain were evaluated. The age distribution was 2.5-16.0 years (mean 11.3 years for girls and 9.9 years for boys). The history showed 17% of patients with chest pain, 22% with heart disease, and 19% with recent death in the family. The time course of the pain was longer than 1 week in 92 patients. Localization was on the left precordium in 60 patients, and there was no radiation from the original site in 66 cases. Ninety-two percent of cases were idiopathic in origin. Of the 74 patients who had a psychiatric interview, 55 (74%) had psychiatric symptoms and 5 required psychiatric care. Anxiety, conversion disorder, and depression were the main psychiatric symptoms.

A comparison between MUGA and echocardiography in patients with muscular dystrophy in the early detection of cardiac involvement.

Muscular dystrophies are a group of sex-linked diseases with frequent myocardial involvement. In this study 14 patients with Duchenne Muscular Dystrophy (DMD), 7 with Becker Muscular Dystrophy (BMD), and 8 female carriers who were asymptomatic were evaluated with echocardiography and multigated radionuclide ventriculography (MUGA). All showed predominant systolic and minor diastolic left ventricular dysfunction determined both by echocardiography and MUGA when compared with healthy controls. In conclusion, it is recommended that DMD, BMD, and female carriers be evaluated and closely monitored for cardiac functions. Though MUGA and echocardiography are both effective and sensitive techniques, echocardiography is more convenient for availability and serial evaluation.

Rheumatic heart disease prevalence among schoolchildren in Ankara, Turkey.

Rheumatic heart disease (RHD) continues to be a common health problem in the developing world. Although little longitudinal data are available, evidence suggests that there has been little if any decline in the occurrence of RHD over the past few decades. There are only a few population surveys available in Turkey for prevalence of RHD. This survey was undertaken to estimate its prevalence among schoolchildren and changes over the last 20 years in the capital, Ankara. In Ankara, 4,086 schoolchildren aged between six and 17 years were screened over a period four months (March 1995-June 1995) by the same pediatrician. Forty-eight percent (n = 1,945) were female and 52 percent (n = 2,141) were male. Three children out of 4,086 (0.73 per 1,000) were noted to have findings consistent with RHD. Fifteen children had an episode of rheumatic fever (RF). Cumulative prevalence rate (prevalence rate for RF history) was 3.7 per 1,000. We concluded that RHD prevalence has decreased in Ankara over the last decades.

Estimation of pulmonary artery pressure by contrast-enhanced Doppler signals and comparison with catheter-measured pressures.

Determination of pulmonary artery systolic pressure (PASP) is essential for the diagnosis, and the timing and type of management of patients with congenital heart disease (CHD). Usually cardiac catheterization, an expensive and invasive technique, is required for accurate measurement. A number of noninvasive methods for the assessment of PASP have been developed, one of which is estimation of PASP using contrast-enhanced tricuspid regurgitation Doppler signals (TRDS). In this study, right ventricular systolic pressures (RVSP) and PASP of 36 patients (19 girls, 17 boys; aged 5 months to 15 years) with CHD were estimated by TRDS before and after galactose solution (GS) and were compared with catheterization measurements. Significant TRDS (> 1 m sec.) were obtained in nine of 36 (25%), patients before GS and in 23 of 36 patients (64%) after GS. TRDS were increased significantly by contrast agent. Estimated RVSP and PASP were significantly different from the measured pressures before and after GS. There were significant correlations between the estimated RVSP and PASP and measured RVSP after GS. Estimated pressures were underestimated. We conclude that it is better to use the estimated PASP on patients with significant TRDS for the classification of PASP.

Pulmonary arteriovenous fistula in the newborn: a case report of Rendu-Osler-Weber syndrome and a review of the literature.

In most instances, congenital arteriovenous fistula is only one manifestation of a more widespread abnormality; 60% of patients also have hereditary hemorrhagic telangiectasis (Rendu-Osler-Weber syndrome). Among those with congenital pulmonary arteriovenous fistula, the diagnosis is made during infancy in only 15% of patients. We present a case of pulmonary arteriovenous fistula in a newborn and review the literature. This rare condition of newborns can be treated with different surgical procedures. Only 17 cases of newborn pulmonary arteriovenous fistula/have been reported, and only two of those had associated Rendu-Osler-Weber syndrome. The results of surgical procedures were good in most of these cases. We treated our case with lobectomy successfully.

A case of mucopolysaccharidoses type I with heart involvement during infancy.

We report a case of mucopolysaccharidoses I with severe cardiac involvement, which was diagnosed on the basis of clinical and laboratory findings even though, symptoms begin to occur in mucopolysaccharidoses after the first year of life. In our case cardiac failure occurred in the third month of life, which resulted in the patient's death after one month.
