"The US Food and Drug Administration issued a safety communication to providers and patients regarding 45 patient deaths and other adverse events associated with SentreHEART devices used for left-atrial-appendage (LAA) closure, including its Lariat suture delivery device[1]."
Although many doctors think that LAA is a worthless area there are others who think that it may in fact have a use which we do not as yet fully understand and therefore not be something we want to remove.
