Hypertrophic cardiomyopathy (HCM) is a cardiac disease characterized by hypertrophy of a nondilated left ventricle without any other cardiac or systemic disease that could account for observed hypertrophy. We present a female patient with the diagnosis of obstructive HCM, which is rare because sudden death is frequently the first clinical presentation. Her symptoms were resistant to medical treatment and the patient did not want invasive procedures. Disopyramide was added, and it improved her symptoms. Disopyramide is a safe and effective medication that reduces symptoms and delays the need for invasive therapy. Disopyramide was added to the treatment of the patient and it improved her symptoms.
