Alcohol septal ablation after failed surgical myectomy

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Surgical myectomy is a primary treatment for obstructive hypertrophic cardiomyopathy.
• Persistent left ventricular outflow tract (LVOT) obstruction and systolic anterior motion (SAM) of the mitral valve can occur post-myectomy.
• Mitral valve replacement is often considered for refractory cases.

Observation:

• A patient presented with severe symptoms and a persistent LVOT gradient despite prior surgical myectomy.
• Systolic anterior motion (SAM) of the mitral valve was noted.
• The patient underwent successful alcohol septal ablation.

Findings:

• Alcohol septal ablation effectively abolished the LVOT gradient.
• The procedure resolved the systolic anterior motion (SAM) of the mitral valve.
• The patient experienced significant symptom improvement.

Implications:

• Alcohol septal ablation is a viable, less invasive alternative to mitral valve replacement in select post-myectomy patients.
• This approach may offer a valuable treatment option for persistent LVOT obstruction.
• Further studies are warranted to evaluate the long-term efficacy and safety of this strategy.
