Key result
Percutaneous transluminal septal myocardial ablation successfully reduced the resting left ventricular outflow tract gradient from 70 mmHg to 0 mmHg, but the patient died suddenly 19 months later with autopsy revealing nontransmural myocardial fibrosis.

Post-ablation fibrosis may contribute to late sudden death in HOCM; single case leaves arrhythmic risk unresolved.
Case Report (n=1)
Successful percutaneous transluminal septal myocardial ablation in hypertrophic obstructive cardiomyopathy can be followed by late sudden death, potentially related to the induced myocardial fibrosis.
Hirata et al. (2003) conducted a case report in Hypertrophic obstructive cardiomyopathy (n=1). Percutaneous transluminal septal myocardial ablation (PTSMA) was evaluated on Resting left ventricular outflow tract gradient (LVOTG). Percutaneous transluminal septal myocardial ablation successfully reduced the resting left ventricular outflow tract gradient from 70 mmHg to 0 mmHg, but the patient died suddenly 19 months later with autopsy revealing nontransmural myocardial fibrosis.
