Positional Ventricular Tachycardia

Abstract

A 60-year-old man showed nonsustained repetitive monomorphic VT in the left lateral position, but this was terminated by deep inspiration. Echocardiography and MRI demonstrated a false tendon extending from the apex to the basal septum where the VT could have originated. Spontaneous remission occurred during the 16-year follow-up.

A surgeon with symptomatic ventricular tachycardia while operating and exacerbated by left lateral decubitus position: Too much of a stretch?

“…In a case report by Betsuyaku et al, 6 the stretch mechanism was postulated as a possible hypothesis for an LV false tendon; however, ablation was not performed. In our case, we not only postulated but also proved that the ventricular ectopy due to positional changes could not be reinduced after ablation of the MB, an RV structure.…”
