Why the study?
The potential of intraoperative transesophageal echocardiography for assessing coronary anatomy and blood flow remains underutilised.
Intraoperative TEE is a valuable tool for assessing coronary anatomy and blood flow, enabling prompt diagnosis and management of acute coronary complications during cardiac surgery.

Intraoperative TEE may facilitate prompt detection of iatrogenic coronary obstruction after valve reoperation; leaves open whether routine coronary flow assessment improves outcomes.
Transesophageal echocardiography (TEE) has become an indispensable part of cardiac surgery, but its potential for assessing coronary anatomy and blood flow remains underutilised. This case report presents a case of acute iatrogenic left main coronary artery obstruction following re-operative aortic valve replacement that was promptly diagnosed by intraoperative TEE and managed successfully by Bentall operation. We also emphasise the technique of TEE for coronary evaluation, its caveats and its clinical application during cardiac surgery.
