Pulmonary stenosis and pulmonary regurgitation: both ends of the spectrum in residual hemodynamic impairment after tetralogy of Fallot repair
Byung Won Yoo, Han Ki Park
Clin Exp Pediatr. 2013;56(6):235-241.   Published online June 21, 2013

Repair of tetralogy of Fallot (TOF) has shown excellent outcomes. However it leaves varying degrees of residual hemodynamic impairment, with severe pulmonary stenosis (PS) and free pulmonary regurgitation (PR) at both ends of the spectrum. Since the 1980s, studies evaluating late outcomes after TOF repair revealed the adverse impacts of residual chronic PR on RV volume and function; thus, a...

Traumatic ventricular septal defect in a 4-year-old boy after blunt chest injury
Yun Mi Kim, Byung Won Yoo, Jae Young Choi, Jun Hee Sul, Young Hwan Park
Clin Exp Pediatr. 2011;54(2):86-89.   Published online February 28, 2011

Traumatic ventricular septal defect (VSD) resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The...

Anomalous origin of left coronary artery arising from the right coronary cusp presenting with chest discomfort and syncope on physical exercise
Ran Baik, Nam Kyun Kim, Han Ki Park, Young Hwan Park, Byung Won Yoo, Jae Young Cho
Clin Exp Pediatr. 2010;53(2):248-252.   Published online February 15, 2010
Anomalous origins of coronary arteries are a rare type of disease among children. These anomalies can be categorized into 3 types according to the anatomical relationship of the aorta and pulmonary trunks. Among these types, the interarterial type, as observed in our case, needs early diagnosis and treatment, because it can increase the risk for the patient, causing sudden cardiac...

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...
A Case of Multiple Giant Coronary Aneurysms with Large Mural Thrombus due to Kawasaki Disease in a Young Infant
Eun Na Choi, Jeoung Tae Kim, Yuria Kim, Byung Won Yoo, Deok Young Choi, Jae Young Choi, Jun Hee Sul, Sung Kye Lee, Dong Soo Kim, Young Hwan Park
Clin Exp Pediatr. 2005;48(3):321-326.   Published online March 15, 2005
Kawasaki disease is an acute systemic vasculitis of unknown origin. Giant coronary aneurysm is one of the most serious complications, although peripheral artery vasculitis can produce life-threatening events. Myocardial ischemia and infarction can be caused by coronary artery stenosis, aneurysm, and stagnation of blood flow in coronary arteries which triggers thromboembolism. Atypical presentation in young infants often interferes with prompt...

Impact of Device Evolution in Transcatheter Closure of Patent Ductus Arteriosus Using Duct-Occlud Coils : Comparison of Mid-term Results
Myung Kwan Kim, Dong Ki Han, Jae Young Choi, Yuria Kim, Byung Won Yoo, Deok Young Choi, Jun Hee Sul, Sung Kue Lee
Clin Exp Pediatr. 2005;48(2):158-164.   Published online February 15, 2005
Purpose : We reviewed the therapeutic results of various Duct-Occlud coils(pfm AG, K ln, Germany) to evaluate the efficacy of the most-recently modified Duct-Occlud coil(Nit-Occlud) in the transcatheter closure of patent ductus arteriosus(PDA), including large defects more than 4 mm in diameter. Methods : Two hundred and five patients who underwent percutaneous PDA occlusion using Duct- Occlud devices from March...
