Dynamical anchoring of distant Arrhythmia Sources by Fibrotic Regions via Restructuring of the Activation Pattern [PDF]
, 2018 Rotors are functional reentry sources identified in clinically relevant cardiac arrhythmias, such as ventricular and atrial fibrillation. Ablation targeting rotor sites has resulted in arrhythmia termination. Recent clinical, experimental and modelling studies demonstrate that rotors are often anchored around fibrotic scars or regions with increased ...

Left ventricular decompression through a patent foramen ovale in a patient with hypertrophic cardiomyopathy: a case report [PDF]
, 2004 The foramen ovale is considered an unidirectional flap-like valvular structure. Yet, it may increase in size and allow a continuous left-to-right shunt in order to reduce left ventricular filling pressures.

Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

A Multi-Trait Approach Identified Genetic Variants Including a Rare Mutation in RGS3 with Impact on Abnormalities of Cardiac Structure/Function [PDF]
arXiv, 2018 Heart failure is a major cause for premature death. Given heterogeneity of the heart failure syndrome, identifying genetic determinants of cardiac function and structure may provide greater insights into heart failure. Despite progress in understanding the genetic basis of heart failure through genome wide association studies, heritability of heart ...

Hemodynamic behavior of stentless aortic valves in long term follow-up [PDF]
, 2014 Objectives Stentless aortic valve replacements show improved hemodynamics due to larger orifice area and lower transvalvular gradients in short and mid-term follow-up.

Ventricular torsional relation to ventricular fiber arrangement [PDF]
arXiv, 2014 Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole.

Comparison between tagged MRI and standard cine MRI for evaluation of left ventricular ejection fraction [PDF]
, 2018 Global left ventricular function is a prognostic indicator and is used to evaluate therapeutical interventions in patients with heart failure. Regional left ventricular function can be determined with tagged MRI.
