Key result
Pre-procedural transoesophageal echocardiography detected left atrial thrombi in only 1.47% of patients undergoing ablation, with zero cases in paroxysmal AF patients without LA dilation.
Why the study?
Does routine pre-procedural TEE identify LA thrombus in all patients with atrial fibrillation undergoing CPVA?
Observational (n=408)
Does routine pre-procedural TEE identify LA thrombus in all patients with atrial fibrillation undergoing CPVA?
Routine TEE prior to CPVA may not be necessary in patients with paroxysmal AF who lack LA dilation or structural heart disease, given the very low incidence of LA thrombus in this subgroup.
No takes yet. Share an insight, caveat, or question.
Routine TEE may not be needed in paroxysmal AF without LA dilation; leaves open broader applicability pending randomized data.
Calvo et al. (2010) conducted an observational in Atrial fibrillation (n=408). Transoesophageal echocardiography (TEE) was evaluated on Incidence of left atrial thrombus. Pre-procedural transoesophageal echocardiography detected left atrial thrombi in only 1.47% of patients undergoing ablation, with zero cases in paroxysmal AF patients without LA dilation.
