Abstract

Clinical significance of coronary flow velocity measurement by transthoracic Doppler echocardiography in 2 patients with unstable angina (UA) was reported. No significant abnormality was observed on electrocardiography. Coronary flow sequence of the left anterior descending coronary artery (LAD) was detected in diastole. Peak diastolic flow velocity was 11.1 cm/s in case 1 and 10.1 cm/s in case 2. On the basis of these data, emergency coronary angiography was performed in both cases. Severe stenosis was observed at the proximal portion of LAD; consequently, emergency coronary angioplasty was performed. Coronary flow velocity measurement is useful as a diagnostic strategy in UA.
