Authors' conclusion

Currently, the majority of patients are treated on an outpatient basis with either shifting from VKA to DOAC or from one DOAC to another. Left atrial appendage closure in this population seems to be reserved for patients with higher bleeding risk or complications of malignant LAA, such as stroke.

Study context

Population
Physicians at European cardiac centres managing malignant left atrial appendage (LAA) (AF patients with SSE despite OAC or LAA thrombus)
Participants
196 physicians
Outcome
Diagnostic and therapeutic pathways for malignant LAA in practice

Main finding

As reported in the abstract

Diagnostic and therapeutic pathways for malignant LAA
  • High confidence in transoesophageal echocardiography (TEE) imaging for LAA thrombus diagnosis
  • Preferred initial treatment: switch to another direct oral anti-coagulant (DOAC), then switch to vitamin K antagonist (VKA), low-molecular-weight heparin, or continued/optimised DOAC dosage; LAA closure the last option
  • LAA closure a viable option in embolic stroke despite OAC with no thrombus at TEE (empty LAA) after comprehensive exclusion of other embolic sources

Observational data: associations, not effects.
