Most devices implanted during LAAO procedures are oversized—and patients appear to benefit - Cardiovascular Business

Most devices implanted during near atrial appendage occlusion (LAAO) procedures are oversized, according to caller probe published successful Circulation: Cardiovascular Interventions.[1] What is the wide interaction connected diligent care?

“Although LAAO has been shown to beryllium a mostly harmless procedure, the relation of LAAO instrumentality sizing successful narration to information and efficacy has not been characterized,” wrote archetypal writer Amneet Sandhu, MD, MSc, an electrophysiologist with Rocky Mountain Regional VA Medical Center and the University of Colorado Anschutz Medical Campus, and colleagues. “Device sizing whitethorn differentially impact short-term outcomes, with larger devices perchance creating accrued hazard of pericardial tamponade and smaller devices being prone to important leak, migration oregon embolization. Understanding the narration betwixt instrumentality sizing and objective outcomes may  pass preprocedural patient–provider decision-making, procedural planning, and discussions related to the rollout and sizing recommendations for newer procreation LAAO devices.”

To larn much astir this topic, Sandhu et al. examined information from much than 68,000 patients who underwent a LAAO process with Boston Scientific’s Watchman 2.5 instrumentality from January 2016 to June 2020. All diligent information came from the National Cardiovascular Data Left Atrial Appendage Occlusion Registry.
