Clinical presentations, diagnosis, and management of arrhythmias associated with cardiac tumors

Journal of Arrhythmia, 2018
Cardiac tumors are a rare cause of arrhythmias in clinical practice. They can cause a broad spectrum of arrhythmias, from low‐grade ectopics to incessant ventricular tachycardias, including sudden cardiac arrest. Both primary and secondary cardiac tumors

Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

Advanced Science, EarlyView.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

Echocardiography and cardiac arrhythmias

Hellenic Journal of Cardiology, 2018
Cardiac arrhythmias refer to any abnormality or disturbance in the normal activation sequence of the myocardium and may be indicative of structural heart disease and the cause of significant cardiovascular complications and sudden cardiac death.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Handgrip strength test for the diagnosis of long QT syndrome

Российский кардиологический журнал
Long QT syndrome (LQTS) assessment is based on the QT/ÖRR equation (the so-called Bazett's formula) and calculating the corrected QT (QTc). However, this formula reliably estimates the QT interval in the heart rate range (HR) of 60-90 bpm, which makes it

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

Advanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.
