Alcohol septal ablation is a minimally invasive procedure used to treat hypertrophic obstructive cardiomyopathy (HOCM) by injecting alcohol into targeted heart muscle. This induces controlled damage, reducing obstruction and symptoms.
It is a catheter-based procedure that involves injecting alcohol into a specific area of the heart muscle to induce controlled damage. This reduces the obstruction caused by hypertrophic obstructive cardiomyopathy (HOCM) and alleviates symptoms.
Patients undergo a comprehensive evaluation, including medical history review, physical examination, and diagnostic tests such as echocardiography and cardiac catheterization.
Anesthesia or conscious sedation is administered to ensure patient comfort during the procedure, typically via an intravenous line.
A catheter is inserted into an artery, usually in the groin, and guided to the area of the heart where the obstruction is located.
Contrast dye is injected through the catheter to visualize the anatomy and identify the specific septal artery supplying the area of hypertrophy.
Once the target artery is identified, a small amount of pure alcohol is injected through the catheter into the septal artery, causing localized damage to the thickened heart muscle.
Throughout the procedure, the patient’s vital signs, ECG, and hemodynamic parameters are monitored closely to ensure safety.
After the alcohol injection, patients are observed in a monitored setting to detect any immediate complications such as arrhythmias or hypotension.
Patients undergo regular follow-up appointments to assess the efficacy of the procedure, monitor for symptom improvement, and adjust treatment as needed. Additional imaging studies may be performed to evaluate changes in cardiac structure and function over time.
Alcohol septal ablation for hypertrophic obstructive cardiomyopathy (HOCM) is primarily performed by interventional cardiologists specializing in structural heart interventions. Additionally, cardiac imaging specialists, electrophysiologists, and cardiac surgeons may be involved in patient evaluation, procedural planning, and post-procedural care, highlighting its multidisciplinary nature.
