Case in brief
A 67-year-old man with familial hypertrophic cardiomyopathy and severe heart failure presented with significant interatrial conduction delay. After excluding cardiac resynchronization therapy, a dual-chamber implantable cardioverter-defibrillator was implanted, utilizing Bachmann bundle pacing for the atrial lead. This approach corrected the interatrial conduction delay, leading to improved left ventricular ejection fraction from 31% to 49% and a reduction in NYHA class from III to II within one month.
Diagnostic / clinical pearl
Bachmann bundle pacing can effectively optimize interatrial synchrony in patients with hypertrophic cardiomyopathy and interatrial conduction delay, leading to significant clinical improvements.
Why it matters
This case highlights the potential of combining Bachmann bundle pacing with implantable cardioverter-defibrillators to enhance hemodynamic function and provide protection against sudden cardiac death in specific patient populations.
