We have read the recent review by Saw and Lempereur (1) with interest because it provides a comprehensive overview of the currently available therapies for transcatheter left atrial appendage (LAA) closure, with a particular emphasis on procedural imaging and techniques (1). However, the review does not accurately reflect the currently available technology with regard to the Lariat procedure (SentreHEART, Redwood City, California). The article repeatedly states that the Lariat procedure is only feasible for LAA diameters <40 mm. The Lariat Plus device has recently become available with a snare diameter of 45 mm (compared with the first-generation device, which had a snare diameter of 40 mm). We have used the Lariat Plus device with success to close an appendage >40 mm in diameter. Other advances in this next-generation device include improved epicardial torque control and radiopaque markers. We thank the editors for the opportunity to provide this important clarification related to the rapidly evolving field of structural heart disease.
