Key result
Catheter ablation successfully treats SVT-triggered aborted sudden cardiac death in INOCA, avoiding AICD placement.
Why the study?
Aborted sudden cardiac death is very uncommon with supraventricular tachycardia, especially in the context of INOCA with significant ECG changes and raised cardiac enzymes.
Case Report (n=1)
This case highlights the rare occurrence of aborted sudden cardiac death secondary to SVT in the setting of INOCA, suggesting ablation as a life-saving intervention.

Ablation may be considered over AICD in rare SVT-related aborted SCD with INOCA; leaves open generalizability from this single case.
Aborted Sudden Cardiac Death (SCD) is very uncommon with supraventricular tachycardia (SVT). However, cases had been reported in SVT associated with ventricular arrhythmias and coronary artery disease. We report an unusual case of Acute coronary Syndrome due to non-obstructive coronary artery disease (INOCA) with significant ECG changes and raised cardiac enzymes; presented with aborted SCD secondary to SVT.

Shah et al. (2026) conducted a case report in Acute Coronary Syndrome due to INOCA with aborted Sudden Cardiac Death secondary to SVT (n=1). Ablation vs. AICD was evaluated. Ablation, rather than an AICD, successfully treated a patient presenting with aborted sudden cardiac death secondary to supraventricular tachycardia in the setting of INOCA.
