Figure 1 Radio-guided surgery during left ventricular remodeling. In vivo analysis of tracer distribution for the differentiation between viable tissue and scar tissue was performed on the epicardial (A and B) and endocardial (C) surfaces of the ventricular chamber.

Figure 2 Presurgical (A) and postsurgical (B) left ventricular volume in end-diastole (EDV) and end-systole (ESV) in patient 1. Restoration of ventricular size and shape resulted in an improvement in stroke volume (SV) and ejection fraction (EF).
