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...

Purpose : The purpose of this study is to determine whether the new pulmonary valve reconstruction technique prevents short-term postoperative pulmonary regurgitation and improves early and mid-term clinical outcome. Methods : We reviewed postoperative echocardiographic variables and chest X-ray films from 31 patients who had undergone valve reconstruction(pulmonary valve reconstruction group : PVR) for the repair of TOF between April 2000...
Morphologic Changes of the Pulmonary Arteries after Stent Implantation on Branch Pulmonary Artery Stenosis - Impact of Pulmonary Insufficiency -
Me Jin Kim, Du Cheol Kang, Jae Young Choi, Jong Kyun Lee, Jun Hee Sul, Sung Kyu Lee
Clin Exp Pediatr. 2003;46(1):67-75.   Published online January 15, 2003
Purpose : Intravascular stent implantation for the treatment of postoperative branch pulmonary artery(PA) stenosis has been used successfully. However, the cross sectional area of contralateral branch PA does not regress in spite of the successful dilation of the stenotic branch PA after stent implantation. We analyzed the morphologic and hemodynamic factors on the size of branch PA after successful...
Volumetric Quantitation of Pulmonary Regurgitation and Right Ventricular Function in Postoperative Tetralogy of Fallot by Echocardiography and Magnetic Resonance Imaging
Eun Young Park, Il Tae Whang, Young Mi Hong, Yong Sun Won, Yun Hyun Choi
Clin Exp Pediatr. 1998;41(11):1530-1537.   Published online November 15, 1998
Purpose : Despite improved surgical techniques, pulmonary regurgitation is a common postoperative sequelae in patients with tetralogy of Fallot. Pulmonary regurgitation may induce deterioration of right ventricular performance, right ventricular dilatation and ventricular arrhythmia. The evaluation of the clinical significance of pulmonary regurgitation in postoperative tetralogy of Fallot has been troublesome since there was no technique that could accurately quantitate...
