Objective
Alcohol septal ablation (ASA) has been shown to be an effective treatment in patients with hypertrophic obstructive cardiomyopathy (HOCM) who are refractory to medical treatment. We describe an alternative approach for septal ablation with Onyx. Onyx consists of Ethylene Vinyl Alcohol Copolymer, soluted in Dimethyl-Sulfoxi
Methods
In our method left coronary ostium was cannulated with 6-8F guiding catheter. Septal branch was cannulated with a 4F catheter and a microcatheter. Onyx was instilled through the microcatheter into the septal artery. Immediate polymerization prevents the leak into the left anterior descending coronary artery, and also to the right coronary artery (RCA) via septal collaterals.
