Efficacy and safety of transcatheter left atrial appendage closure guided by transoesophageal echocardiography using standard and micro TEE probes: a single-center retrospective study
To evaluate the efficacy and safety of micro-TEE compared with standard TEE guidance specifically during transcatheter left atrial appendage closure (T-LAAC).
Key Findings:
46 patients were included; 38 procedures under standard TEE and 8 under micro-TEE.
Procedural success rates were similar; one failure in the standard TEE group due to device sizing.
No significant differences in periprocedural complications between the two groups.
Micro-TEE guidance resulted in shorter procedural time (153 vs. 175 min, p = 0.040) and lower orotracheal intubation rates.
At 1-month follow-up, the micro-TEE group did not show increased complication rates.
Interpretation:
Micro-TEE during T-LAAC did not significantly differ in procedural success or complication rates compared to standard TEE, but it significantly reduced procedural time and the need for orotracheal intubation.
Limitations:
Single-center study may limit generalizability.
Potential selection bias due to clinical discretion in choosing imaging guidance.
Retrospective nature of the study may affect data reliability.
Conclusion:
Micro-TEE is a viable alternative to standard TEE for T-LAAC, offering similar safety and efficacy with reduced procedural time.
