Intraoperative Doppler spectrum analysis of blood flow in the internal mammary artery used for myocardial revascularization.

Intraoperative Doppler-derived measurements of blood flow velocity were used to characterize the hemodynamics in 6 internal mammary artery grafts before and after anastomosis to the left anterior descending artery. Pulsed Doppler spectrum analysis demonstrated a change from a systolic to a predominantly diastolic flow pattern. The presented technique is a… CONTINUE READING
