Figure 1
A: First unipolar ablation procedure, right anterior oblique view. B: Radioablation treatment plan images, axial (above) and frontal (below) views. C: Electrocardiogram of the ventricular tachycardia on the admission (speed = 25 mm/s).

Figure 2
A: Left: activation map of the LV endocardium with the white color, representing the earliest activation site in the middle of the ALPM (white arrow). Right: Activation map of ALPM inside the LV shell. B: Diastolic potential recorded at the body of the ALPM by ablation catheter (on the left, yellow arrow) and by the multielectrode catheter (on the right, red arrow). C: Suggested VT mechanism. ALPM = anterolateral papillary muscle; LV = left ventricle; VT = ventricular tachycardia.

Figure 3
A: Termination of the ventricular tachycardia (white arrow) during the unipolar ablation. B: Ablation points: blue, bipolar; red, unipolar. C and D: Catheter positions for the bipolar ablation of the papillary muscle. Abl 1 = ablation catheter transseptal; Abl 2 = ablation catheter transaortic; CS = coronary sinus, RV = right ventricle.
