Key result
Routine use of CT for left atrial appendage closure sizing resulted in 0 device-related complications and 0 severe leaks, altering device size selection in over half of cases compared to TOE.
Why the study?
Does routine incorporation of CT in addition to TOE improve sizing accuracy and procedural safety in patients undergoing LAA closure?
Observational (n=73)
No
Does routine incorporation of CT in addition to TOE improve sizing accuracy and procedural safety in patients undergoing LAA closure?
Routine use of CT for LAA closure sizing is associated with excellent procedural safety and frequently alters device size selection compared to TOE alone, avoiding gross sizing errors.
No takes yet. Share an insight, caveat, or question.
CT may enhance LAA closure sizing accuracy; leaves open whether routine addition improves outcomes versus TOE alone.
Rajwani et al. (2016) conducted an observational in Percutaneous left atrial appendage (LAA) closure (n=73). Computerized tomography (CT) sizing vs. Transoesophageal echocardiography (TOE) was evaluated on Device-related procedural complications and severe leaks. Routine use of CT for left atrial appendage closure sizing resulted in 0 device-related complications and 0 severe leaks, altering device size selection in over half of cases compared to TOE.
