Novoheart

: CUSTOM-DESIGNED SUBSTRATE

Proprietary design to reproduce electrical conduction pattern of native heart.

: DIRECT MEASUREMENT

Offers unprecedented direct visualization and measurement of cardiac arrhythmias.

: ARRHYTHMIC RISK

Arrhythmic risk can be quantified using hvCAS under drug treatment or disease conditions.

Traditional in vitro electrophysiological measurements are limited to single-cell data that fail to reveal cell-to-cell properties, such as conduction and re-entrant waves or to recapitulate physiological cardiac properties, such as cellular alignment and anisotropic conduction.

Novoheart's human ventricular Cardiac Anisotropic Sheet (hvCAS) model is the first validated multi-cellular optical approach for quantifying risk towards cardiac arrhythmias. Our proprietary microfabricated substrate aligns stem cell-derived cardiomyocytes to mimic structural and functional anisotropic properties of the human heart.

The hvCAS platform is available as two options:

(Cat. No. 2-01) Microfabricated polystyrene substrate (Circular disc with 1.5cm diameter, with 8-µm, 10-µm or 15-µm grooves for increasing levels of cell anisotropy)
8/10/15 µm width x 5 µm depth and 5 µm ridge
(Cat. No. 2-02) Microfabricated polystyrene substrate with custom dimensions

Cardiac Toxicity Screening: identification of pro-arrhythmic compounds, chronotropes and dromotropes.
Disease Modeling: studies on human channelopathies.
Drug Discovery: drug screening and efficacy assessment of pro-arrhythmic compounds, chronotropes and dromotropes.
Regenerative Studies: studies on electrophysiological maturation in human cardiomyocytes.
