Background: Radiofrequency (RF) catheter ablation is an effective method of treatment of patients with WPW syndrome. The purpose of this study was to analyze the initial and follow-up results of RF ablation of such cases in our hospital. Methods: 255 cases with WPW syndrome that had delta wave in sinus rhythm ECG underwent electrophysiological studies in this hospital. All the cases underwent radiofrequency ablation. These cases are selected for analysis. Results: Ablations were performed in these 255 patients between December 2005 and December 2008. One accessory pathway (AP) was found in 250 patients, two accessory pathways-in 05 patients. The mean duration of the procedure was 130 ± 32 min. The initial and overall success rate was 92.15% and 95.68% respectively. Major complications encountered are none. Conclusions: RF ablation of WPW syndrome has good initial (92.15%) and overall (95.68%) success rate and low recurrence rate (5.00%) at long term follow-up.

Long Term Follow Up

AbstractFifty-nine type 1 tympanoplasties in children under 14 years of age were assessed by recall to a special follow-up clinic up to 15 years post-operatively. Overall 78 per cent of tympanic membranes were found to be intact with a late failure of grafts noted in 6 per cent of cases. An improvement in the audiological threshold was found in 51 per cent, 24 per cent were unchanged, the remaining 25 per cent suffered a deterioration which was seen both immediately post-operatively and thereafter until reviewed in the special clinic. The age at operation, size of the perforation, grade of surgeon carrying out the operation and prior adenoidectomy had no statistically significant influence on the success rate or the audiologicaloutcome. Revision procedures achieved similar graft take rates to the initial procedures but fared worse audiologically. We conclude that in the majority the operation was successful but hearing gain was not as good as expected and subject to late deterioration. A long term follow-up is important to detect this and other complications.

Long Term Follow Up

Introduction: Endo-epicardial catheter ablation of ventricular tachycardia (VT) in patients (pts) with nonischemic cardiomyopathy (NICM) has been reported to have satisfactory results at the short- and mid-term follow-up. We sought to determine the outcomes at the long-term follow-up of endo-epicardial ablation of VT in NICM. Hypothesis: Catheter ablation provides satisfactory long term outcome Methods: We prospectively enrolled 128 pts (age 59±13 years, 116 [91%] males) with NICM who underwent endo-epicardial radiofrequency catheter ablation at our Institution. After substrate mapping, all critical sites for the clinical or induced VT(s), identified with activation, entrainment or pace-mapping, together with late, split and fractionated potentials were targeted with focal and/or linear ablation. The procedural endpoint was noninducibility of sustained monomorphic VT. Pts were followed with ICD interrogation. Results: A total of 108 (73%) pts had idiopathic dilated NICM. The remaining 20 (14%) pts had hypertrophic CM (n=11), suspected inflammatory CM (n=6), or valvular CM (n=3). The mean LV ejection fraction was 33±15%. After a mean follow-up of 19 months (max 97 months), a total of 36 (28%) pts died and 17 (13%) underwent heart transplant. Cumulative survival free from any recurrent VT was 53% (68/128 patients) (Figure A). In the remaining 60 (47%) patients with VT recurrences, catheter ablation still resulted in a significant beneficial clinical impact on VT burden, with 25/60 (42%) having only isolated (1-2) VT episodes over follow-up, and a striking reduction of VT storm in the remaining pts (Figure B). Conclusions: In patients with NICM and VT, endo-epicardial substrate-based ablation is effective in achieving long-term freedom from any VT in 53% of patients, with a substantial improvement in VT burden in many of the remaining patients.
