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.

Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).

Atrioventricular nodal (AVN) ablation with permanent pacemaker implantation – ‘pace and ablate’ – may be considered for patients with symptomatic atrial fibrillation (AF) for whom rhythm control has been unsuccessful. Conduction-system pacing mitigates PICM, so we expect a greater uptake of AVN ablation going forward.

Hypertrophic cardiomyopathy is a genetic disorder with a guarded prognosis which occurs in about 1:500 individuals.
