ENGLISH ABSTRACT: The left atrial appendage (LAA) is considered to be a vestigial remnant of the primitive foetal atrium. It has also been identified as the source of the majority of left atrial thrombi in nonvalvular atrial fibrillation (AF). Not having a clearly defined and recognised function, and having the reputation of being the villain in thrombotic stroke in patients with non-valvular AF, has led to a number of rather aggressive interventions targeted at dealing with the scourge of AF.
