Objective:

To examine the association between Cabrol shunt and the incidence of new-onset postoperative atrial fibrillation (POAF) after surgery for acute type A aortic dissection (AAAD).

Approach:

Key Findings:

• Patients in the non-Cabrol shunt group had a higher incidence of new-onset POAF than those in the Cabrol shunt group (P = 0.013).
• Age and aortic cross-clamp time were independent factors influencing the occurrence of new-onset POAF.

Interpretation:

Cabrol shunt use was associated with a lower observed incidence of new-onset POAF in patients undergoing AAAD surgery.

Limitations:

• Retrospective design may introduce selection bias.
• Missing data related to echocardiographic parameters could affect results.

Conclusion:

The study suggests a potential association between Cabrol shunt use and reduced incidence of new-onset POAF in AAAD surgery.
