Abstract

Transthoracic coronary Doppler echocardiography (TCDE) can be useful for the detection of chronic total occlusion (CTO) of the proximal left anterior descending coronary artery (LAD) noninvasively, by detecting retrograde flow through the distal LAD or its septal branch. This intriguing case report details the detection of abnormal blood flow in the right ventricular free wall by TCDE. This detection of abnormal flow may be useful to predict CTO of the LAD, even in the absence of retrograde flow in the LAD and its septal branch.

Keywords: Doppler echocardiography; coronary flow imaging.
