Intraoperative TEE is crucial for early detection of regional wall motion abnormalities, facilitating prompt diagnosis and life-saving intervention for acute coronary obstruction following aortic valve replacement.
Intraoperative TEE may aid detection of rare post-AVR obstruction; leaves open need for prospective validation before practice change.
Acute coronary artery obstruction is a rare but potentially fatal complication of aortic valve replacement (AVR) surgery This adverse event can be induced by sudden coronary spasm, embolization of calcium plaque on the coronary arterial walls or aortic root, or intraoperative iatrogenic events
