A single episode of atrial fibrillation in patients with a CHA₂DS₂-VASc score ≥2 often leads to a recommendation for lifelong anticoagulation. But is this always necessary? This article explores when exceptions may be reasonable, the importance of rhythm monitoring, and how shared decision-making can guide personalised, safe stroke prevention strategies.
Transoesophageal echocardiography before atrial fibrillation cardioversion prevents stroke by detecting hidden left atrial appendage clots. The greatest risk comes from atrial stunning after rhythm restoration, not existing thrombus. TOE enables safe early intervention.
Mammalian hearts, including humans, feature two atria - the left and the right. These chambers serve as reception areas, collecting blood before it's dispatched to the ventricles. This system bears a resemblance to a turbocharger in an engine, where the atria boost the heart's efficiency, preparing it for a powerful contraction.
With growing public awareness and knowledge, there is an understandable and increasing interest in patients employing self help techniques to look out for AF episodes. After all, it is hardly going to be possible to obtain an ECG from your GP every time you feel a slightly irregular pulse.
