Background:
Left atrial appendage (LAA) thrombus is a contraindication for LAA closure (LAAC). However, in selected cases, oral anticoagulants are strictly contraindicated because of a history of life-threatening bleeding, and LAAC remains the only possible therapy to avoid systemic and especially cerebral embolization.
Case Summary:
We report a case of LAAC despite a massive proximal thrombus in a patient who had an absolute contraindication to anticoagulant therapy, with thorough pre-planning using CT scan, device modelling and thrombus trapping techniques to reduce the risk of systemic embolic events and perform LAAC safely.
Discussion:
Although LAAC remains at high risk in this setting, the use of cautious techniques and tools, from pre-procedure planning to systemic embolization prevention systems associated to a precise transoesopheageal echocardiography guiding throughout the procedure, allows it to be performed as safely as possible when no other option is available.
