Spatial orientation of cross-sectional images of coronary arteries: point of view in intracoronary imaging.

abstract：BACKGROUND:Transthoracic echocardiography (TTE) may be used for direct inspection of various parts of the main coronary arteries for detection of coronary stenoses and occlusions. We aimed to assess the feasibility of TTE to visualise the complete segments of the left main (LM), left descending (LAD), circumflex (Cx) a...
