title: Assessment of left ventricular functions in patients with isolated coronary artery ectasia by conventional and tissue Doppler imaging.
abstract: The authors sought to determine left ventricular functions by conventional and tissue Doppler imaging in patients with isolated coronary artery ectasia and controls. Peak early (E) and late (A) mitral inflow velocity, E/A ratio, E deceleration time, and isovolumetric relaxation time were obtained. Peak systolic velocity (Sm), diastolic early (Em), and late (Am) velocities were measured by tissue Doppler imaging. Interventricular septum velocities, including peak systolic (Ss), diastolic early (Es), and late (As) velocities, were recorded. Peak early (E) velocity, E/A ratio, and E deceleration time were different in both groups. Isovolumetric relaxation time was prolonged in patients with coronary artery ectasia than controls. Em and Em/Am ratio were lower in patients with coronary artery ectasia than controls. Diastolic early and Es/As velocities were lower in patients with coronary artery ectasia compared with controls. The authors showed that mitral inflow-lateral annulus and interventricular septum velocities were lower in patients with coronary artery ectasia than controls indicating left ventricular diastolic dysfunction.
