introduction: hearing impairment is the most frequent sensorial congenital defect in newborns and has increased to 2–4 cases per 1,000 live births. sensory-neural hearing loss (snhl) accounts for more than 90% of all hearing loss. this disorder is associated with other congenital disorders such as renal, skeletal, ocular, and cardiac disorders. given that congenital heart diseases are life-thre...

anomalous origin of the left coronary artery from the pulmonary artery (alcapa) is a rare congenital cardiac malformation. we report three cases of alcapa who survived to adulthood. the first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with alcapa using cardiac catheterization and coronary computed tomographic angiography (cta). the second case was a 30-...

the purpose of this study was to evaluate the early and late outcome after total correction of tetralogy of fallot (tof) in 101 consecutive patients with a mean age of 8.23 ± 4.90 years underwent repair of surgery at one institution between 1995 and 2006. forty two patients had initial palliative operations. a transannular patch was inserted in 60 (58.5%) patients. risk factors for operative mo...

conclusions in the children in this study, pacemaker accelerometers failed to meet physiological demands. results basal heart rates, maximal heart rates, and exercise tolerance were significantly lower in the children with pacemakers. age, sex, and body mass index had no effect on the heart rate slope during the exercise test. there was no significant difference between epicardial and endocardi...

T HE CLINICAL and hemodynamic findings in patients with complete heart block have been reported by many authors.1-14 There is general agreement that irrespective of the etiology of the block, cardiac enlargement and increased stroke volume are the compensatory mechanisms for the slow rate. In a few studies ventricular rate and other hemodynamic changes have been followed during exercise.1-3' 13...
