AB  - BACKGROUND: Radiofrequency (RF) ablation of idiopathic ventricular arrhythmias 
      (IVA) from the coronary venous system (CVS) has been increasingly performed, but 
      real effect of ablation lesions from CVS on epicardial myocardium has not been 
      studied. OBJECTIVE: To compare effects of RF delivered inside the distal CVS 
      during ablation of IVAs originating from left ventricular summit (LVS) with IVAs 
      ablated from right ventricular outflow tract (RVOT) using cardiac magnetic 
      resonance imaging (CMRI). METHODS: Twenty consecutive patients with IVAs who 
      underwent acutely successful RF ablation at initial appropriate sites, i.e., 
      distal CVS (Group 1, n = 10) or RVOT (Group 2; n = 10) were enrolled. Detailed 
      contrast-enhanced CMRI of each patient was performed 3 months later. Presence and 
      location of scars, distance of CVS to epicardial ventricular myocardium were 
      measured and analyzed. RESULTS: Group 1 consisted of 10 and Group 2 consisted of 
      10 patients. Three months after the ablation, only three patients in Group 1 had 
      detectable late gadolinium enhancement (LGE) on CMRI while nine out of 10 
      patients in Group 2 had evident LGE on CMRI (P: 0.02). The mean distance of 
      distal CVS to epicardial anterobasal myocardium was measured to be 8.8 +/- 1.6 mm 
      in Group 1. In three cases that had detectable scar on superior anterobasal LV 
      epicardium, the mean distance was 7.4 +/- 1.1 mm. CONCLUSIONS: RF delivery inside 
      the CVS is less likely to produce detectable LGE on CMRI compared to RVOT. This 
      may partially explain less than ideal long-term results after ablation of LVS 
      IVAs from within the great cardiac vein/anterior interventricular vein.
