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.

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

  5. Patient has other medical illness not related to the hypertrophic cardiomyopathy (e.g., cancer, known malignancy, or cognitive heart failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non-compliance with the protocol, confound the data interpretation or is associated with limited life expectancy (i.e., less than 1 year)
