Abstract
- A 66-year-old man with a history of diabetes mellitus presented with angina pectoris with 3-vessel disease, and he underwent off-pump coronary artery bypass grafting via median sternotomy. After performing bypass grafting of the left internal thoracic artery to the left anterior descending artery, the appearance of anastomosis configuration appeared to be acceptable. However, transit time flow measurement (TTFM) showed that the mean graft flow was 10 mL/min, which was less than expected despite an acceptable flow curve with a diastolic flow pattern, a pulsatility index (index of resistance) of 2.0, and diastolic filling (proportion of diastole with coronary flow) of 65% (Figure 1). In addition to TTFM, the …
