Abstract:
Objective To explore the usage of anatomic al M-mode echocardiography in observing pulmonary artery motion curve of pulmonary hypertension patients.Methods The subjects included 21 pulmonary hypertension patients complicated with tricuspid valve insufficiency, and 21 controls whose age and gender matched with the patient group. The inner diameter of main pulmonary artery and right atrium, acceleration time of pulmonary valve Doppler signal and maximum velocity of tricuspid insufficiency (ACTpv) were measured during routine echo examination. From the maximum velocity of tricuspid insufficiency the pulmonary artery systolic pressure (PASP) was calculated. The pulmonary artery motion curve and pulsating amplitude of pulmonary artery wall (PAWPA) was observed and measured with a home-made anatomical M-mode echocardiography with instrument. Results PAWPA in the patient group was lower, and simultaneously complicated with broader pulmonary artery, larger right atrium and shorter ACTpv in comparison with normal group (all P
