Percutaneous myocardial ablation for left mid-ventricular obstructive hypertrophic cardiomyopathy.

Mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHC) is a rare type of cardiomyopathy. The diagnosis is based on the hourglass appearance on the left ventriculogram and the presence of pressure gradient between apical and basal chamber of the ventriculum on the hemodynamic assessment. Atrio-ventricular sequential pacing and alcohol ablation have been proposed as less invasive alternatives to surgery for patients who fail to respond to pharmacologic therapy. The present case represents successful percutaneous treatment with alcohol ablation to patient with MVOHC and apical aneurysm. Alcohol ablation to distal segment of the left anterior descending artery resulted with relief of clinical symptoms and intra-ventricular pressure gradient.
