Abstract Background The coexisting of transposition the great arteries (TGA) with total anomalous pulmonary venous connection (TAPVC) is one rare anomalies. incidence TAPVC and TGA unknown very few cases ever reported. Case presentation We reported a case 13-month-old female toddler history cyanosis. Echocardiography revealed atrioventricular ambiguity atresia, all PVs drain into innominate vei...
BACKGROUND The pulmonary venous flow velocity pattern (PVFVP) in atrial septal defect (ASD) has not been previously studied in detail. Normally, PVFVP is primarily determined by the left heart performance. We hypothesized that the impact of left-sided heart dynamics on PVFVP is diminished in patients with ASD because of the presence of a left-to-right shunt into the low-resistance right side of...
Background The purpose of this study was to determine the effect of stress on left-to-right shunting in patients with atrial septal defect (ASD) and to investigate if the degree of shunting, cardiac output (CO), and right ventricular (RV) volumes are related to exercise capacity. Methods Twenty-six patients with a secundum ASD and 16 healthy volunteers were studied with rest/stress cardiac ma...
OBJECTIVE Transcatheter closure of secundum atrial septal defect (ASD) with Amplatzer device is an alternative procedure to surgical repair, with some limitations. The aim of this study was to assess the initial and mid-term results of the treatment of ASD with Amplatzer septal occluder in children and adolescents. METHODS From May 2003 to January 2008 sixty three consecutive children and ado...
ASD and more frequently the ostium secundum type is a relatively common adult congenital heart disease. Sjogren’s syndrome on other side second most frequent auto immune disease, Involving lungs in 9–20% of patients. We report case 69 years old woman, complaining long-standing dyspnea was diagnosed with syndrom. Her CT scan pulmonary function tests were normal. That lead to investigate for hype...
OBJECTIVES We sought to evaluate the course of cardiopulmonary function after transcatheter atrial septal defect (ASD) closure and to identify the physiopathologic mechanisms leading to this change. BACKGROUND Conflicting reports exist on cardiopulmonary functional improvement in asymptomatic adults after transcatheter closure of a secundum ASD. METHODS Thirty-two consecutive adults (13 mal...
Objective: To assess the short-term outcome following transcatheter closure of secundum atrial septal defect (ASD) in our hospital. Patients and Methods: Between June 2000 and November 2001, 20 patients diagnosed as secundum atrial septal defects underwent transcatheter closure of their defects using the Amplatzer septal occluder (ASO) device. Indications for 18 patients were larger atrial sept...
Congenital heart disease (CHD) is the most common form of congenital human birth anomalies and a leading cause of perinatal and infant mortality. Some studies including our published genome-wide association study (GWAS) of CHD have indicated that genetic variants may contribute to the risk of CHD. Recently, Cordell et al. published a GWAS of multiple CHD phenotypes in European Caucasians and id...
OBJECTIVES The purpose of this study was to estimate the frequency of NKX2.5 mutations in specific cardiovascular anomalies and investigate genotype-phenotype correlations in individuals with NKX2.5 mutations. BACKGROUND Recent reports have implicated mutations in the transcription factor NKX2.5 as a cause of various congenital heart defects (CHD). METHODS We tested genomic deoxyribonucleic aci...
