Analysis of phasic flow velocity dynamics in the left anterior descending coronary artery before and after angioplasty using transthoracic echocardiography in patients with stable angina pectoris.

Author information

Regional Cardiac Unit, Papworth Hospital, Cambridge, United Kingdom.


High-frequency transthoracic Doppler echocardiography was used to determine the effects of significant stenosis on distal coronary blood flow velocity profiles. Before coronary angioplasty there was a reduction in diastolic and systolic flow and diastolic/systolic peak velocity ratio. After successful angioplasty velocity ratios returned to normal.
