Video 35.12 Contrast echocardiography to guide alcohol septal ablation
Contrast echocardiography to guide alcohol septal ablation. Apical 4-chamber image in adult view during alcohol septal ablation procedure. There is basal septal hypertrophy. Administration of agitated saline into the first septal branch opacifies only the basal interventricular septum, suggesting that alcohol septal ablation of the first septal perforator will lead to regression in basal septal hypertrophy and intraventricular gradients.
