Contact Affiliations. 4. With the exception of one patient in whom a significant gradient persisted after septal ablation, after the periprocedural period, patients after septal reduction therapy remained free of recurrent bleeding and need for transfusions. We aimed to demonstrate that septal myectomy is efficacious in reducing or abolishing left ventricular outflow tract gradient and leads to long-lasting symptom-atic improvement in most patients.
