  Purpose

The purpose of the study is to perform endocardial catheter CRyo-Ablation to relieve the LVOT obstruction in patients with Hypertrophic Obstructive Cardiomyopathy.

The investigators hypothesize that the investigators will be able to reduce > 50% of the initial LVOT gradient. This will be considered as a successful procedure.
