AB  - A 77-year-old man with frequent monomorphic ventricular premature contractions 
      (VPCs) was referred for catheter ablation. Detailed mapping just above the 
      pulmonary valve (PV) revealed tiny fragmented potentials earlier than the VPC 
      onset. Perfect pace-mapping was obtained using high voltage pacing just above the 
      PV and the left aortic sinus of Valsalva, whose stimulus-to-VPC latencies 
      differed by 20 ms. While the ablation at the pulmonary valve could not completely 
      eliminate the VPCs, unipolar sequential ablation on both sides of the outflow 
      tracts led to their successful abolition that was guided by perfect pace-mapping.
