Abstract:
Many patients have now been able to receive transcatheter aortic valve replacement (TAVR) therapy for severe aortic stenosis. These patients have atrial fibrillation and are placed on warfarin for stroke prophylaxis. The opportunity for treatment with left atrial appendage occlusion (LAAO) in place of warfarin for this population exists, especially for those with increased bleeding risk. This paper discusses the prevalence and aetiology of stroke in patients presenting for TAVR (with a focus on the risk from chronic and acute atrial fibrillation) and also the benefit of LAAO closure in this population.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
