Abstract

Purpose – Intravenous leiomyomatosis (IVL) is a very rare subtype of leiomyoma, involving the right obstruction of the heart, and is an unusual cause of outflow tract obstruction. The IVL grows from the vessel’s smooth muscle, protruding into the vessel’s lumen, and can expand to the right atrium and even beyond causing death due to blood flow obstruction into the right atrium and even to pulmonary artery.

Design/Methodology/Approach – We present a 33-year-old Indonesian woman with cardiopulmonary symptoms predominantly, and marked by an intravascular leiomyoma extending from inferior vena cava (IVC) to right chamber atrium, with the chief complaint being easily fatigued since seven months.

Findings – Echocardiography observations found a mass in the right atrium and the IVC that caused dynamics obstructed in tricuspid valve, right atrium and ventricle were dilated, no left ventricular (LV) hypertrophy, normal LV and right ventricular (RV) functions, and no valve abnormality except the tricuspid valve gradient being 21 mmHg with mild regurgitation. Venography resulted in a mobile tumor mass in IVC mouth which partially flew into the right atrium, and partially blocked the IVC mouth. Tumor size was 6.4 cm × 4.8 cm. Abdominal multislice computed tomography resulted in a residual soft tissue mass (leiomyoma) along the IVC extended to the right atrium. The tumor mass size in the IVC and the right atrium was bigger compared to tumor mass on July 2008. The correct diagnosis was established during surgery; therefore a two-stage resection was done.

Originality/Value – Surgical resection is the best treatment for intracardiac extension of intravenous leiomyoma. To remove the ilio-caval portion, iliac venotomy was recommended for the tumor in both stages of the surgeries.

Abstract

Purpose

The purpose of this paper is to introduce the RWTH's total artificial heart, ReinHeart, focusing on the design of the unique drive system.

Design/methodology/approach

The force characteristics of the drive have been simulated in a finite element (FE) approach. Additionally the coppler losses within the motor coils have been predicted based on the FE‐simulation. Both results are compared to laboratory measurements of a prototype to validate the design.

Findings

The presented results show a good correlation between simulation and measurement and proof the applicability of the new design drive system.

Research limitations/implications

The used hydraulic models of the cardiovasular system used as a load for the device are not fully validated with data from living organisms. Therefore, further in vivo trials are needed.

Originality/value

The high force density of the drive allows its integration into a fully implantable, total artificial heart, in order to significantly improve durability. This hopefully will extend the indication for artificial hearts as alternatives to transplantation.

Abstract

Purpose

The purpose of this paper is to define the key components of an effective regulatory regime.

Design/methodology/approach

The paper takes the form of a critical analysis.

Findings

Regulatory arbitrage has been one of the major factors contributing to the severity of the crisis. Given the ever more complex set of future regulatory constraints, it may keep generating costly negative spillover effects on the whole economy. Moreover, rules‐based regulation, however carefully constructed, will unfortunately never prevent bank failures. Neither should it attempt to do so. An effective overall regulatory regime must be sufficiently comprehensive and well‐balanced. It must not put too much emphasis on lowering the probability of individual bank failure. The key components of an effective regulatory regime must be: Basel‐type rules robust to off‐balance‐sheet arbitrage; little forbearance in monitoring and supervision by regulatory agencies, with a focus on systemic risk control; automatic and quick intervention as well as resolution mechanisms. While all components are necessary, none is sufficient; and without strong international coordination, none will be effective.

Practical implications

Enhanced supervision of banks.

Social implications

Less costly bank failures.

Originality/value

The paper presents a critical review of current financial reforms in the banking sector.

Abstract

RETIRING prime ministers are customarily offered an earldom. Because this often involves a change of name and historical oblivion, some of the greatest among them, men like Pitt and Gladstone and Churchill, have declined the honour. They understood that it is not names which give confidence in things, but things which give confidence in names. What would an Earl Chartwell of Westerham mean to future generations compared with the clarion voice we know as Churchill?

Abstract

Companies over the world faced several risks related to the COVID-19 crisis. However, when quoting those risks, it is common to mix up pandemic effects with general consequences of work at home or the use of electronic communication channels. At the same time, a lot of indirect effects of the crisis are not straightforward, and some consequences may only turn evident in the long term. This chapter collects different appearances and implications of the risk caused by the epidemic based on literature review, questionnaires, in-depth interviews, and expert panels with a particular emphasis on the findings from Hungary. The authors conclude that risk effects differ little across countries but rather widely across industries and individuals. The risk map presented clarifies critical connections and offers a structured overview for the first time in the literature. A better understanding of the risk effects may assist managers and regulators when another similar crisis would emerge in the future.
