Figure 1
A: A 2-dimensional echocardiogram (modified parasternal long-axis view) depicting the extent of the intramyocardial cardiac mass localized inferolaterally. B: Positron emission tomography and computed tomography with F-fluorodeoxyglucose image showing low uptake of F-fluorodeoxyglucose within the tumor (maximum standardized uptake value of 3.24 and mean value of 2.0 are within the range typical for benign tumors). C: The extent of the tumor as seen during cardiac surgery and cryoablation probe at the border zone of the tumor.

Figure 2
A: Electrocardiogram recordings of predominant clinical ventricular tachycardia with right bundle branch block morphology and left axis deviation, suggestive of origin close to the lower septum. B: Three-dimensional electroanatomical bipolar voltage map of the left ventricle (modified left lateral view) showing normal voltage (violet color) and 2 regions of catheter ablation close to the posteromedial papillary muscle and the other superiorly in the basal part of ventricle (black arrows).
