Don’t Forget the Sinuses: an important site for some infarct-related VT

The aortic sinuses of Valsalva are an important ablation site in non-ischemic substrates and in patients with idiopathic ventricular arrhythmias. Siontis and colleagues have demonstrated that these sites should also be considered for ablation in patients with infarct-related inferior axis VT. Low voltage in the aortic sinuses of Valsalva or in the sub-aortic region should prompt further evaluation of these regions for ablation.
