In this two-part series, we discuss the anatomical basis for arrhythmias arising above
the semilunar valves. In this part (part I), we describe the relevant anatomy and
technique for mapping and ablation of ventricular arrhythmias arising above either
the pulmonic or the aortic valve. After an initial discussion of the underlying anatomy
and characteristics of the substrate targeted for ablation above the semilunar valve,
an approach for safe and effective ablation of supravalvar ventricular arrhythmias
is presented.
