Key result
Thrombus trapping during LAAC is feasible, with a ~2% 30-day major adverse event rate.
Why the study?
Although the presence of a thrombus contraindicates LAAC, the feasibility and short-term outcomes of the thrombus trapping procedure (TTP) technique to overcome this limitation were not well established.
Observational (n=53)

Hypothesis-generating for thrombus trapping in LAA closure; randomized trials needed before practice change.
Garot et al. (2022) conducted an observational in Left atrial appendage thrombus (n=53). Thrombus trapping procedure (TTP) during LAAC was evaluated on 30-day occurrence of stroke, systemic embolism or cardiovascular death. The thrombus trapping procedure during left atrial appendage closure was feasible and safe, with the 30-day composite of stroke, systemic embolism, or cardiovascular death occurring in 1.9% (1 of 53) of patients.
