The overall success rate of surgery for obstructive hypertrophic cardiomyopathy is more than 80%, depending on the patient’s condition, the severity of the disease, and the level of medical care received.
For patients with symptomatic obstructive hypertrophic cardiomyopathy, drug therapy is the first line of treatment. If significant symptoms of heart failure still exist after the maximum dose of drug therapy, surgical treatments such as interventricular diaphragmotomy or ventricular septal alcohol ablation are needed, and studies have shown that the success rate of interventricular septal myotomy is 90%-95%, and the success rate of interventricular septal alcohol ablation is 80%-90% after the surgery.
Ventricular septal myotomy generally provides immediate relief and sustained results for mitral valve insufficiency combined with obstruction after surgery, while septal alcohol ablation delays relief for up to 3 months. Both procedures have their own advantages and disadvantages, and a specialized physician is needed to formulate a surgical plan that takes into account the patient’s actual condition.
Hypertrophic cardiomyopathy is a hereditary cardiac muscle disease. When left ventricular outflow tract obstruction occurs, patients will experience symptoms such as dyspnea, fatigue, chest pain and syncope, etc. It is recommended that people with family history or the above clinical symptoms seek medical treatment as soon as possible in order to avoid serious consequences.
