Diagram of a Cross-Sectional View of the Heart at Midventricular Level Showing AHI Location
Left: untreated. Right: after treatment. Bottom: calculation of wall stress from Laplace law. σ = wall stress, AHI = alginate hydrogel implants; h = wall thickness; LV = left ventricle; P = intracavitary pressure, R = cavity radius; RV = right ventricle.
