Late aortic root dilatation and aortic regurgitation in repaired tetralogy of fallot
Jeong Eun Kim, Kyong Hur, Hae Sik Kwon, Byung Won Yoo, Jae Young Choi, Jun Hee Sul
Clin Exp Pediatr. 2007;50(10):976-981.   Published online October 15, 2007
Purpose : Aortic valve or aortic root (AoRo) replacement is occasionally required because of AoRo dilatation and aortic regurgitation (AR) in repaired tetralogy of Fallot (TOF). We evaluated AoRo size and possible factors associated with its hemodynamic nature in patients with repaired TOF. Methods : We investigated 130 repaired TOF patients more than 15 years of age who followed-up by...
Comparison of defect size measured by transthoracic and transesophageal echocardiography with balloon occlusive diameter measured during transcatheter closure of atrial septal defect
Kyong Hur, Jeong Eun Kim, Yuria Kim, Hae Sik Kwon, Byung Won Yoo, Jae Young Choi, Jun Hee Sul
Clin Exp Pediatr. 2007;50(10):970-975.   Published online October 15, 2007
Purpose : Accurate measurement of defect size is important in transcatheter closure of atrial septal defect (ASD). We performed this study to analyze the difference between the measured ASD size and balloon occlusive diameter (BOD) by transthoracic (TTE) or transesophageal echocardiography (TEE). Methods : We investigated 78 patients who underwent transcatheter closure of ASD. The defect size and the distance between...

Stent implantation to relieve secondary pulmonary venous stenosis in total anomalous pulmonary venous connection: case report
Youn Ho Shin, Ki Eun Kim, Hae Sik Kwon, Byung Won Yoo, Jae Young Choi
Clin Exp Pediatr. 2007;50(9):919-924.   Published online September 15, 2007
Pulmonary venous stenosis may be congenital or acquired. Regardless of its origin, the prognosis for patients affected with PVS remains poor. There have been many attempts to palliate PVS with little success. This report describes two patients with PVS which became evident after repair of total anomalous pulmonary venous connection. Intravascular stents were successfully implanted, but progressive restenoses in the...

Follow-up Studies and Clinical Significance of Chromosomal Rearrangement in Childhood Acute Lymphocytic Leukemia
Yang Hyun Kim, Jung Tae Kim, Jung Chul Kang, Hae Sik Kwon, Sung Chul Won, Seung Hwan Oh, Chuhl Joo Lyu
Clin Exp Pediatr. 2004;47(8):861-867.   Published online August 15, 2004
Purpose : Through routine screening for chromosomal defects present in patients with acute lymphocytic leukemia(ALL) by means of reverse transcription-polymerase chain reaction(RT-PCR), we aimed for earlier detection of recurrences, hence evaluating the progress of the disease after treatment, and forecasting the need for further testing. Methods : We analyzed 30 patients who visited the Pediatrics Department of Severance Hospital, from...
