The instant mean gradient represents a more physiological measurement than the relationship between the systolic pressure of the right ventricle and the systemic pressure, because this relationship will be affected by multiple factors; i.e., in the case of systemic hypotension the ratio increases but does not represent a change in the degree of obstruction of the RVOTF.
El gradiente medio instantáneo representa una medida más fisiológica que la relación entre las presiones sistólica del ventrículo derecho y sistémica, debido a que esta relación se va a ver afectada por múltiples factores.
