Abstract The hemodynamic effects of a patent ductus arteriosus (PDA) are well known including systemic hypoperfusion and volume overload on the left ventricle. This article aims to provide a review of the long-standing effect of a hemodynamically significant PDA on the pulmonary vasculature and the role of cardiac catheterization in preterm infants with a PDA and pulmonary hypertension.

Abstract There continues to be controversy on the long‐term effects of a patent ductus arte‐ riosus (PDA) and its management. However, the hemodynamic effects of a large PDA in a preterm infant are well known. This article aims to provide insight into the adap‐ tive changes and remodeling effects of a PDA on the myocardium in preterm infants. More >

Abstract Objective: Advancements in transcatheter technology have now made it possible to safely close patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants. The objective of this article is to describe our technique for transcatheter PDA closure (TCPC) in ELBW infants.
Design: The techniques employed are very specific to this population and are drasti‐ cally different when compared to the procedure performed in patients weighing >5 kg.
Setting: A multidisciplinary team approach should be taken to evaluate and manage ELBW infants in order to achieve success. It is important that specific techniques with venous‐only approach outlined in this article… More >

Abstract The world-wide impact of traumatic injury and associated hemorrhage on human health and well-being is significant. Methods to manage bleeding from sites within the torso, referred to as non-compressible torso hemorrhage (NCTH), remain largely limited to the use of conventional operative techniques. The overall mortality rate of patients with NCTH is approximately 50%. Studies from the wars in Afghanistan and Iraq have suggested that up to 80% of potentially survivable patients die as a result of uncontrolled exsanguinating hemorrhage. The commercially available resuscitative endovascular balloon occlusion of the aorta (REBOA) is a percutaneous device for the rapid control of torso… More >

Abstract The purpose of this study is to investigate the deformational behavior and strength of the catheter which is made from the soft nylon resin and is reinforced with thin stainless wires called braid. When we image the usage conditions of catheter in the actual surgical operation, it is expected that the multi-axial loading for tension, torsion and the bending are applied and deformations occurring in the catheter become very complicated. As the first step of this study to reveal these phenomena, the combined loadings for tension and torsion are chosen as the subject of this study and we carry out… More >
