Transcatheter Closure of Secundum Atrial Septal Defect with \Buttoned\" Device"
Jong-Kyun Lee, Seok Min Choi, Jo Won Jung, Jun Hee Sul, Sung Kyu Lee, Jin Yong Lee, Hae Yong Lee
Accepted January 1, 1970  
Purpose : Recently, non-operative transcatheter management of congenital heart defects h as increased due to their effectiveness and safety being acknowledged. In the case of secundu- m atrial septal defect(ASD), closing devices have been developed since 1974 and have been u sed clinically. The authors, having tried the "Buttoned" device which was developed in 1990 an d having succeeded in...

Morphological Classification of Left Superior Vena Cava and Analysis of Associated Cardiac Anomalies
Eun Joo Choi, Jong Kyun Lee, Seok Min Choi, Jun Hee Sul, Sung Kyu Lee

The persistend left superior vena cava(LSVC) is not rare cardiovascular developmental anomaly occurring both in association with congenital heart disdease and as an isolated anomaly of no hemodynamic importance. We have studied 73 cases of the LSCV out of 1,060 cases of congenital heart disease catheterized at Yonsei Cardiovascular Center. We conducted the study with a view point of position of...
Echocardiographic Evaluation of the Changes of the Interventricular Septal Morphology in Postoperative Tetralogy of Fallot Patients

The hemodynamic feature of the tetralogy of Fallot (TOF) is best characterized by equality of left and right ventricular peak systolic pressure. The interventricular septum is flattened and thickened. Even after the right ventricular pressure is normalized in the postoperative period, the morphological abnormality continues for some time. We have analyzed the morphological changes of the IVS echocardiographically after total...
Tricuspid Atresia : A Re-evaluation and Classification
Jun Hee Sul, Jong Kyun Lee, Seok Min Choi, Sung Kyu Lee
Clin Exp Pediatr. 1993;36(12):1716-1720.   Published online December 15, 1993
Morphological evaluations accounting the associated anomalies were performed in the 60 cases of tricuspid atresia, diagnosed at Divsion of Pediatric Cardiology. The following results were obtained. 1) Twenty one out of the 6 cases had transposition of the great vessels, among which 8 cases were in complete A-transposition. 2) Seven cases were associated with pulmonany atresia, in 1 case, aorts arise from...
Clinical study on the factors used in the diagnosis of heart failure.
Dong Chul Park, Seok Min Choi, Jun Hee Sul, Sung Kyu Lee, Dong Shik Chin

Heart failure is the state in which heart cannot produce the cardiac output required to sustain the metabolic needs of the body without evoking certain compensatory mechanisms. As these mecha- nisms become ineffective, increasingly severe clinical manifestations result. The diagnosis of conges- tive heart failure relies on several sources of clinical findings, including history, physical examination, and chest X-rays. For lack of uniform diagnostic...
Clinical Study of Hypophosphatemic Rickets.
Seok Min Choi, Duk Hi Kim, Chin Suck Suh
Clin Exp Pediatr. 1989;32(8):1057-1063.   Published online August 31, 1989
Hypophosphatemic rickets is a disorder characterized by a normal or slightly reduced serum calcium level, a moderately reduced serum phosphorus level and elevated alkaline phosphatase activity. The usual mode of inheritance is X-linked dominant and postulated mechanism is a selective disorder of tubular reabsorption of phosphate, defective conversion of 21-hydroxyvitamin D3 to calcitriol and increased catabolism of calcitriol. In children with renal hypophosphatemic rickets, growth...
Hypokalemic Periodic Paralysis.
Seok Min Choi, Jong Kyun Lee, Pyung Kil Kim
Clin Exp Pediatr. 1988;31(11):1499-1501.   Published online November 30, 1988
Periodic paralysis is a group of illness characterized by episodic attacks of muscle weakness with complete or nearly complete recovery of strength between attacks. In hypokalemic form, serum potassim level is usually low during the paralytic phase. But the basic defect is unknown. We have experienced a case of hypokalemic periodic paralysis in a 7-year-old girl who had intermittent attacks of flaccid paralysis of...
