Does transthoracic coronary Doppler echocardiography detecting abnormal blood flow in the right ventricular free wall predict chronic total occlusion of the left anterior descending artery?
Detection of abnormal epicardial flow in the right ventricular free wall via transthoracic coronary Doppler echocardiography may serve as a novel noninvasive sign of LAD chronic total occlusion.
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.
