TL;DR: The results suggest that markedly dilated pulmonary arteries easily compress the left main coronary trunk and cause narrowing, which improves after atrial septal defect closure.
Journal ArticleDOI
The criteria for reconstruction of right ventricular outflow tract in total correction of tetralogy of Fallot
TL;DR: It is revealed that, in order to improve the operative outcome in this anomaly, it is necessary to correct pulmonary stenosis to the point of the right-to-left ventricular peak pressure ratio (PRV/LV) less than 0.8 as well as preventing severe pulmonary insufficiency.
Journal Article
Physical Phenomena and Porosity Prevention Mechanism in Laser-Arc Hybrid Welding
TL;DR: In this article, the effects of welding conditions and melt flows on penetration depth, geometry and porosity formation were investigated with the X-ray transmission real-time observation method, and the effect of melting flow on porosity suppression in TIG-YAG hybrid welding of stainless steels or aluminium alloys was investigated.
Journal ArticleDOI
Indication of aortocoronary by-pass for coronary arterial obstruction due to Kawasaki disease.
TL;DR: Six patients with coronary arterial lesions due to Kawasaki disease underwent aortocoronary by-pass grafting at the institute and the following guidelines are proposed as an indication for aorto-by-pass in such patients.
Journal ArticleDOI
Effect of oxygen in ambient atmosphere on penetration characteristics in single yttrium aluminum garnet laser and hybrid welding
TL;DR: Welding with a yttrium-aluminum-garnet (YAG) laser only or with hybrid source combined with a YAG laser and a TIG arc was carried out on Type 304 stainless steel plate with low S content in the air or in the chamber with Ar gas including 0% -15% oxygen gas as discussed by the authors.
