Wild Type Transthyretin Amyloid Cardiomyopathy Hidden Under Ablation‐Refractory Atrial Arrhythmias and the Potential Contribution of Tafamidis in Rhythm Control
An octogenarian man with a history of multiple catheter ablation failures for atrial fibrillation and tachycardia was diagnosed with transthyretin amyloid cardiomyopathy. After 1 year of tafamidis therapy, the patient experienced spontaneous restoration of sinus rhythm, and follow-up image of 99mTc-pyrophosphate scintigraphy revealed a marked decrease of tracer accumulation.
