Externally applied compression therapy for Fontan patients

Fontan circulation: the search for targeted therapy.

T he Fontan operation has been the final palliation for children born with congenital heart defects with a functional single ventricle for >4 decades. In the early days of the Fontan operation, focus was rightly on technical modifications and alterations in strategy in an attempt to decrease morbidity and mortality related to the operation itself. 3 In recent years, that focus has shifted towar...

Compression therapy in obese patients

Triggered by obesity, venous (obesity-associated dependency syndrome) and lymphatic drainage disorders (obesity-associated lymphoedema) can develop, which in themselves require compression therapy, or other comorbidities with indication for compression therapy may exist. In obese patients, some specific features have to be observed in compression therapy: An adequate initial decongestive phase ...

Control of sawtooth oscillation dynamics using externally applied stellarator transform

The control of sawtooth oscillations is an active area of tokamak research. Large sawtooth oscillations need to be avoided in ITER, since these large sawteeth couple to neoclassical tearing modes and edge localized modes resulting in serious confinement degradation. Small sawtooth oscillations, however, may be beneficial in preventing impurity and helium ash accumulation in the center of the pl...

Full toroidal plasma response to externally applied nonaxisymmetric magnetic fields

The plasma response to resonant magnetic perturbation RMP and nonresonant perturbation fields is computed within a linear, full toroidal, single-fluid resistive magnetohydrodynamic framework. The response of resonant harmonics depends sensitively on the plasma resistivity and on the toroidal rotation. The response of nonresonant harmonics is not sensitive to most of the plasma parameters, excep...
