The detonation of an IED near a military vehicle induces different damage effects on the vehicle and its occupants. There are local effects from fragments and projectiles but there are also global effects from a momentum transfer on the complete vehicle structure and a subsequent dynamical motion of the vehicle with phenomena like overturning or vehicle displacement from the *** like this can be answered with numerical finite-element simulations but there is also the need for engineering tools that allow a quick and nearly instantaneous simulation of these phenomena. The following work presents an approach for a fast analysis of global IED effects on vehicles. The physical modelling is based on analytical formula and empirical data that describe the momentum transfer of a detonation on a nearby structure. This momentum is the initial condition for the calculation of the following vehicle motion and the simulation of vehicle dynamics and jump *** software itself has a modern GUI that allows the generation of the vehicle structure and the threat scenario together with an interactive analysis of the simulation *** engineering tool is validated with small size generic vehicle tests where jump height and the vehicle motion are compared. The software allows a detailed analysis of global IED effects and can be additionally used in an inverse mode for the analysis of incidents with the determination of used HE masses in an IED attack.

Surgical-interventional hybrid orchestra consisting of Potts shunt, transcatheter tricuspid valve repair by Edwards-valve in a 26-year-old patient with pulmonary hypertension and right ventricular failure

Reported here is a 26-year-old patient with corrected congenital interrupted aortic arch admitted with massive hemoptysis and severe suprasystemic pul-monary hypertension provided him for heart-lung transplantation. Initial closure of a small aorto-pulmonary collateral remained ineffective. Persistent life-threatening hemoptysis led to the decision for a modified Potts shunt with the aim of decompressing the right ventricle and avoiding pulmonary-hypertensive crisis. The hemoptysis did not recur. However, the patient’s oxygen transport condition deteriorated and necessitated an orchestra of interventional-surgical approaches from re-coarctation stenting, Potts shunt flow reducing to surgical and transcatheter tricuspid valve repair with transient ECMO before the patient could be discharged home.
