Abstract:
A 25-year-old male with an atrial tachycardia-induced cardiomyopathy (TIC) presented to our institution with clinical heart failure, an ejection fraction of 10%, and a severely dilated left ventricle. He underwent successful ablation and had no recurrence of this arrhythmia. In this report, we document the acute and long-term follow-up (out to 10 years) of a single patient with a TIC and present the changes in left ventricular (LV) function and dimensions that occurred. Despite the apparent success of ablative therapy, this case report highlights the importance of routine clinical and echocardiographic follow-up in patients with longstanding TIC.
