Abstract/OtherAbstract:
With the continued development of genetically engineered mouse models of cardiac disease, further advancement of noninvasive techniques for evaluating cardiac diastolic dysfunction in these models would be valuable. Therefore, we performed comprehensive transmitral and pulmonary venous Doppler echocardiographic studies to devise novel indices of diastolic function in a mouse model with cardiac hypertrophy, which were validated against invasively measured hemodynamic parameters. We examined 10 HopX(Tg) transgenic mice with diastolic dysfunction and 10 age-matched controls sedated with 1% to 2% isoflurane (male, age 14-18 weeks). These studies revealed that the acceleration time of the transmitral Doppler E-wave was the best Doppler parameter for unmasking LV diastolic dysfunction in HopX(Tg) mice. This is the first study to assess the utility of the acceleration time of the E-wave and pulmonary venous Doppler echocardiography as a primary diagnostic modality for assessing murine diastolic function.
