Implication

Extends experimental LV mechanics data in arrested canine hearts; leaves open in vivo or clinical translation.

Structured PICO

Population

7 isolated, potassium-arrested dog hearts

Intervention

Inflation of a left ventricular balloon to 20-30 mmHg

Comparator

Zero pressure state

Outcome

Transmural distribution of three-dimensional strainsurrogate

In isolated arrested canine left ventricles, circumferential and longitudinal strains increase from epicardium to subendocardium, whereas fiber strain shows no significant transmural variation.
