1.Right Ventricular Area, Dimension, and Volume Measured by Two-dimensional Echocardiography in Normal Children.
Journal of the Korean Pediatric Society 1994;37(10):1340-1349
The usefulness of two-dimensional echocardiography to measure the right ventricular volume was assessed in 58 normal children (mean age 5 years and 3 months). From the apical 4-chamber view (A4CV), the subcostal RV sagittal view (SCRVSV), the subcostal right anterior oblique view (SCRAOV), and the subcostal RV coronal view (SCRVCV), the dimensions and areas of the right ventricle were measured. The right ventricular volumes and ejection fractions were calculated from these data by pyramid model and single plane area/length method. We could obtain subcostal right ventricular sagittal view in 98%, apical 4-chamber view in 90%, subcostal right anterior oblique view in 79%, and subcostal right ventricular coronal view in 71% of our children. The areas and dimensions correlated with all growth indices, such as age, height, weight, and body surface area. In general the areas showed higher correlation with body surface area, and dimensions with height. correlations of parameters obtained from the subcostal right anterior oblique view and subcostal right ventricular sagittal view with the growth indices were better than those of the subcostal right ventricular coronal view. The calculated right ventricular volume and ejection fraction showed a great varibility depending on the model used. The right ventricular volume calculated by pyramid model correlated better with the growth indices than that by single plane area/length method. the right ventricular volume calculated from the apical 4-chamber view dimension and the subcostal right ventricular sagittal view area by pyramid model is the model which showed the best correlation with growth indices. Right ventricular ejection fraction did not change with any growth indices. Among the right ventricular volumes and ejection fractions by single plane area/length method, the volume(59.9+/-29.9 ml/m(2)) and ejection fracton (58.7+/-10.9%) from the subcostal right anterior oblique view were similar to those (51.0+/-17.3ml/m(2), 51.3+/-10.2%) calculated from the apical 4-chamber view dimension and the subcostal right ventricular sagittal view area by pyramid model. The subcostal right anterior oblique view reflects three parts of the right ventricle. Its area and dimension are well correlated with growth indices. Also the right ventricular volume and ejection fraction obtained by single plane area/length method using the subcostal right anterior oblique view correlate with the growth indices. Therefore the subcostal right anterior oblique view is the most valuable single view representing the right ventricle.

4.Medical management of adults with congenital heart disease.
Korean Journal of Pediatrics 2006;49(9):937-945
The population of adult patients with congenital heart disease(CHD) has increased dramatically because of improved survival of infants and children with CHD. There are still a substantial number of adults with unrepaired CHD. Many adult patients do not know the possible problems of their disease such as ventricular dysfunction, arrhythmia, and what they should pay attention to. They often consider themselves "cured" or "healthy" if only they don't have overt symptoms, and visit hospitals only after deterioration of their problems. Some patients are neglected because they cannot be corrected surgically although careful medical support can improve their survival and quality of life. It is, therefore, essential that the patients, their families, and physicians understand the potential problems of CHD and need for regular follow-up. In this paper we will take a brief review for common medical problems of repaired or unrepaired CHD and also mention a few specific diseases which are common in adults.

Atrial flutter is and infrequent, but potentially unstable tachyarrythmia that occurs in pediatric ages. Transesophageal atrial pacing was used for treatment of 10 episodes of atrial flutter in 7 patients. At the time of atrial flutter conversion, patients were 6 days to 14 years old. 6 patients had associated with congenital heart disease. The atrial cycle length of atrial flutter ranged from 140 to 280 msec with variable atrioventricular conduction. Transesophageal atrial pacing was performed using a bipolar 4 F transesophageal electrode catheter. Atrial flutter conversion was accomplished with stimulation bursts using about 5 seconds of stimuli, 10 msec in duration at 20 to 27 mA. Pacing cycle length was 45 to 110 msec less than the atrial cycle length of tachycardia in 6 episodes. But in a neonate, underdrive pacing converted atrial flutter to sinus rhythm. Conversion attempts were unsuccessful on 2 occasions. Transesophageal atrial pacing is a safe and effective, minimally invasive technique for treatment of atrial flutter in infants and children.
