The Doppler wave form along the proximal left internal thoracic artery (LITA), which is detected by the parasternal or suplaclavicular view, shows a different pattern from that of the distal side of the LITA due to the effect of blood pulsatility from the subclavian artery. We evaluated postoperative LITA function immediately after surgery with an apical approach of transthoracic pulsed Doppler echocardiography in 124 patients and compared its results with that of one month postoperative Doppler findings and graft angiogram. The LITA was effectively detected and good quality Doppler waveforms obtained in 120 (96.8%) patients. The LITA diameter was significantly enlarged in the first month af..View full abstract
