Mavacamten is a cardiac myosin inhibitor that has been shown to reduce left ventricular outflow tract obstruction in obstructive hypertrophic cardiomyopathy (oHCM).1 1 In late-stage clinical trials, atrial fibrillation (AF) represented an adverse event in 2-4 % of the patients randomized to mavacamten.1,2

When atrial fibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. A fibrillatory wave that occurs at a rate of more than 600 beats per minute can cause fatigue in the long run, leading to atrial dilation.

In patients with hypertrophic cardiomyopathy (HCM), atrial fibrillation (AF) poses significant clinical challenges because of its adverse impact on hemodynamics. AF, especially when accompanied by rapid ventricular responses, compromises atrial contraction and in turn increases diastolic filling of the left ventricle.
