1. Abnormalities of Cardiac Situs and Heart Disease Diagnosed by Echocardiography in Patients with Biliary Atresia
Abstract Background: Left isomerism (LI) is a common finding in patients with biliary atresia (BA), and it can be identified by echocardiography. Several comorbidities may be present in patients with LI, including heart disease. Objective: To investigate the prevalence of LI and heart disease in children (< 18 years of age) with BA followed-up at Hospital

2. Coexistent Mitral Stenosis and left Circumflex Coronary Artery to left Atrial Fistula in a Patient with Severe Pulmonary Hypertension
Abstract Coronary artery to left atrial fistula is rare in patients with mitral stenosis. We report an interesting case of a patient with concomitant mitral valve stenosis and coronary fistulae, originating from the left circumflex artery and drained into the left atrium with two terminal orifices.

3. Congenital Supravalvar Mitral Ring - A Case Report
Abstract Congenital mitral valve stenosis is a rare and severe disease, usually associated with other heart defects. The appropriate intervention depends on the site and mechanism of valvular obstruction and the aim is to avoid or delay valve replacement since it is associated with significant morbidity and mortality. Early single-stage complete repair is as

5. Predictors of Unfavourable Outcomes in Children and Adolescents Submitted to Surgical Mitral Valvuloplasty Secondary to Chronic Rheumatic Heart Disease
Resumo Fundamento: A plastia da valva mitral, em pacientes pediátricos com cardiopatia reumática crônica, é superior à troca valvar e vem sendo utilizada com bons resultados. Objetivo: Identificar variáveis preditoras de desfecho desfavorável em crianças e adolescentes submetidos à valvoplastia mitral cirúrgica secundária à cardiopatia reumáti

6. Chronic Atrial Fibrillation Ablation with Harmonic Scalpel during Mitral Valve Surgery
Abstract Objective To evaluate surgical treatment of chronic atrial fibrillation with ultrasound in patients with mitral valve disease, considering preoperative clinical characteristics of patients undergoing surgical procedure and follow-up in the immediate postoperative period, in hospital and up to 60 months after discharge. Methods: We studied 100 pati

7. Detecção da microdeleção 7q11.23 por MLPA® e estudo clínico dos pacientes com síndrome de Williams-Beuren / Detection of the microdeletion 7q11.23 by MLPA® and clinical study of patients with Williams-Beuren syndrome
INTRODUCTION: Williams-Beuren syndrome (WBS) is a genetic disorder caused by a microdeletion in 7q11.23 region. It is characterized by typical facial dysmorphisms, mental retardation, hipersociable behavior, congenital heart disease, mainly supravalvular aortic stenosis (SVAS), and other variable congenital malformations. METHODS: 65 patients (40 males, 25 f

8. Short- and long- term results of percutaneous balloon valvuloplasty in pulmonary valve stenosis
Objective - To assess the long-term results of percutaneous balloon valvuloplasty at a single institution. Methods - This study comprised 189 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty from 1984 to 1996, whose mean age was 7.97±9.25 years. The procedure was classified as successful when the RV-PA gradient was reduce

9. Candida albicans meningitis in an infant with noonan syndrome
Noonan syndrome is a rare disorder, characterized by several malformations such as dysplasia and stenosis of the pulmonary valve, atrial septal defect and a typical pattern of hypertrophic cardiomyopathy. We describe here a 1-month old girl, who was referred to our center with seizure and apnea. She had wide anterior fontanel, head circumference and sunset e

10. Study of PTPN11 and KRAS genes in patients with Noonan and Noonan-like syndromes / Estudo dos genes PTPN11 e KRAS em pacientes afetados pela síndrome de Noonan e pelas síndromes Noonan-like
INTRODUCTION: Noonan syndrome shows autosomal dominant inheritance, and is a relatively frequent disease in the population, with an estimated incidence between 1/1000 and 1/2500 live births. The main clinical features are: facial dysmorphisms, short stature, cryptorchidism and cardiac abnormalities. The differential diagnosis between Noonan syndrome and Noon

11. Efeitos hemodinâmicos da ventilação não invasiva com pressão positiva em pacientes com estenose mitral sintomática / Hemodynamic effects of positive pressure noninvasive ventilation in patients with symptomatic mitral stenosis
Background: Continuous positive airway pressure (CPAP) impacts hemodynamic changes in heart failure patients by impending cardiac filling and reduces cardiac afterload by reducing left ventricular transmural pressure. These effects may collaborate for the success of this therapy in patients with pulmonary congestion. However, to your knowledge, no study has

12. Williams-Beuren syndrome: cardiovascular abnormalities in 20 patients diagnosed with fluorescence in situ hybridization
OBJECTIVE: To evaluate the cardiovascular findings and clinical follow-up of patients with Williams-Beuren syndrome. METHODS: We studied 20 patients (11 males, mean age at diagnosis: 5.9 years old), assessed for cardiovascular abnormalities with electrocardiography and Doppler echocardiography. Fluorescence in situ hybridization (FISH) was used to confirm th
