Pressure Gradients

Right ventricular hypertrophy was produced in normal dogs: in six by means of pressure overload (pulmonary artery banding) and in six by means of volume overload (systemic arteriovenous fistula). A greater degree of hypertrophy resulted from the latter procedure. Right ventricular hypertrophy due to chronic pressure overload causes a greater degree of infundibular constriction and much higher pressure gradient than in normal animals or in animals with volume overload. Infundibular pressure gradients associated with severe hypertrophy due to volume overload are not significantly greater than those observed in normal dogs. Infundibular gradients are dominantly related to narrowing of the outflow tract.
