Recurrence of Left Ventricular Outflow Tract Obstruction Requiring Alcohol Septal Ablation after Transcatheter Aortic Valve Implantation

Figure 1

(a) The first septal branch was confirmed beforehand. (b) Tip injection into the septal branch using a 2 mm balloon. (c) Total occlusion of the septal branch was confirmed after alcohol injection. (d) Transesophageal echocardiography confirmed the perfusion area of the septal branch as a bright area by contrast injection. (e) Alcohol was administered into the septal branch. (f) Finally, pressure gradient at the left ventricular outflow tract was decreased.
