Implication
May support ablation to reverse VT-induced cardiomyopathy; leaves open generalizability and requires prospective trials.
Key Points
- Investigate the impact of radiofrequency ablation on ventricular tachycardia-induced cardiomyopathy.
- Catheter ablation was conducted on a patient with dilated cardiomyopathy and sustained ventricular tachycardia.
- Electrophysiological testing was performed to reproduce ventricular tachycardia using isoprenaline infusion.
- Follow-up assessments of left ventricular ejection fraction were conducted one month and one year post-ablation.
- Left ventricular ejection fraction improved from 38% to 48% one month after ablation.
- Patient remained free from arrhythmia without medication during the one-year follow-up period.
- Ejection fraction further improved to 61% one year after ablation.
Structured PICO
Does transcatheter radiofrequency ablation improve left ventricular ejection fraction in a patient with ventricular tachycardia-induced cardiomyopathy?
P
Population
1 patient with dilated cardiomyopathy (ejection fraction 38%) and a long history of repetitive palpitations due to ventricular tachycardia.
I
Intervention
Transcatheter radiofrequency ablation delivered to the right ventricular outflow tract.
O
Outcome
Improvement in left ventricular ejection fraction and freedom from arrhythmia.surrogate
Radiofrequency catheter ablation of ventricular tachycardia can successfully reverse tachycardia-induced dilated cardiomyopathy.
