No clinical implications from chick embryo data; leaves open the role of regional wall stress in mammalian cardiac morphogenesis.
In the stage 18 embryonic chick heart, peak active intramyocardial pressure in the subepicardial and subendocardial layers is significantly larger than ventricular pressure, indicating regional variations in wall stress that may influence morphogenesis.
Chabert et al. (2002) studied Embryonic chick heart. Intramyocardial pressure (IMP) and ventricular pressure (VP) measurement was evaluated on Intramyocardial pressure (IMP) and ventricular pressure (VP). Peak active intramyocardial pressure in the subepicardial and subendocardial layers of the stage 18 embryonic chick heart was four to five times larger than peak active ventricular pressure.
