Percutaneous transluminal septal myocardial ablation in hypertrophic cardiomyopathy
Background:
Percutaneous transluminal septal myocardial ablation (PTSMA) is a new interventional technique to treat patients with hypertrophic cardiomyopathy.
Methods:
Small doses of ethanol 96% were injected into a targeted septal artery causing a chemical myocardial infarction. Three patients were evaluated, including a follow-up of three months.
Results:
There were no complications during the procedure LVOT gradient was reduced from 120±140 mmHg. At follow-up, all three patients showed improvement in validity.
Conclusion:
The method requires an echocardiographic contrast determination of the myocardium at risk for ethanol treatment, in addition to haemodynamic monitoring.
