1.3 Transthoracic Echocardiography
Transthoracic echocardiography examinations were performed using a
Philips EPIQ CVx color Doppler ultrasound diagnostic instrument equipped
with an X5-1 transducer (frequency range: 1-5 MHz) at 1 week, 6 months,
and 12 months post-PCI. Both conventional echocardiography and
three-dimensional ”full-volume imaging” were conducted by a physician
with 10 years of experience in echocardiography.
