Key result
Intraoperative TEE detects a new LAA thrombus in an AF patient, enabling prompt heparin therapy.
Why the study?
Perioperative newly developed left atrial appendage thrombus is a rare but extremely challenging event for anesthesia management, making prompt identification and diagnosis crucial.

TEE is valuable for monitoring and detecting newly developed perioperative LAA thrombosis in high-risk patients with atrial fibrillation undergoing non-cardiac surgery.
May support intraoperative TEE monitoring in high-risk AF non-cardiac surgery; hypothesis-generating and requires prospective validation.
BACKGROUND: Perioperative newly developed left atrial appendage (LAA) thrombus is a rare but extremely challenging event for anesthesia management. It's important to identify and diagnose thrombosis in high-risk populations promptly. CASE PRESENTATION: In the case of an elderly patient with atrial fibrillation undergoing non-cardiac surgery, we recorded the findings before and after thrombosis during the operation using transesophageal echocardiography (TEE). Through timely detection of the thrombus and proactive management, a satisfactory therapeutic effect was ultimately achieved. CONCLUSIONS: Clinicians should be aware of the potential risk of LAA clot formation during surgery, even if it was not detected preoperatively. And TEE is valuable for monitoring newly developed perioperative thrombosis.

Li et al. (2023) conducted a case report in Atrial fibrillation (n=1). Transesophageal echocardiography (TEE) and intravenous heparin was evaluated. Intraoperative transesophageal echocardiography successfully detected a newly formed left atrial appendage thrombus in an 84-year-old patient with atrial fibrillation, allowing for prompt treatment with intravenous heparin.
