Physiologic assessment of ostial left circumflex coronary artery disease using a Doppler guidewire before and after rotational atherectomy facilitated angioplasty.
Intravascular Doppler assessment of coronary flow velocity has demonstrated the physiologic significance of intermediate stenoses and the success of coronary interventions. We describe a patient where Doppler evaluation confirmed the significance of an intermediate left circumflex ostial stenosis. We also describe the Doppler flow velocity characteristics after successful rotational atherectomy facilitated angioplasty.
