Abstract Background The status of SNPs among patients with extremely early-onset lone AF and the association with outcome of catheter ablation has not been evaluated before. This study evaluated the status of single nucleotide polymorphisms (SNPs) in Korean patients with early-onset (<40 years old) lone AF and effects on the outcome after catheter ablation. Methods A total of 89 consecutive patients (mean age 35.7±3.7 years, 81 males) with drug-refractory AF (paroxysmal 64.0%) who underwent catheter ablation were included. Sixteen SNPs including rs13376333, rs10465885, rs10033464, rs2200733, rs17042171, rs6843082, rs7193343, rs2106261, rs17570669, rs853445, rs11708996, rs6800541, rs251253, rs3807989, rs11047543 and rs3825214 were genotyped. Serial 48-day Holter electrocardiographic recordings were acquired to detect AF recurrences during long-term follow up. Results Wild type of rs7193343 [CC; 0/7 (0%) vs. CT; 22/40 (55.0%) vs. TT; 18/41 (43.9%), p=0.025] and rs11047543 [GG; 26/69 (37.7%) vs. GA; 13/18 (72.2%) vs. AA; 0/0, p=0.009] and homozygous variant of rs3825214 [AA; 16/31 (51.6%) vs. AG; 22/43 (51.2%) vs. GG; 2/13 (15.4%), p=0.05] were significantly associated with lower rate of late recurrence. When the patients were assigned to four groups according to the number of risk alleles (n=0–3), Kaplan-Meier survival analysis showed incremental prognostic value according to the number of variant alleles (p=0.002) (Figure 1). Figure 1 Conclusions Polymorphisms on rs7193343, rs3825214 and rs11047543 modulate the risk for AF recurrence after catheter ablation during long term follow up in Korean patients with early-onset lone AF.

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.

Antenatal steroids (ANS) are proven strategies to maximize outcomes of premature neonates without any major maternal side effects. Their use results in decreased incidence of neonatal mortality and major morbidities (respiratory distress syndrome, early onset sepsis, necrotizing enterocolitis, and intraventricular hemorrhage). However, due to concerns of long-term adverse effect (early onset hypertension and poor neurological outcome), a close follow-up is required. Similarly, due to lack of long-term follow-up data and potential risk of hypoglycemia, a cautious use is recommended in late preterms and elective cesareans. There is currently no consensus regarding preferential use of one ANS over the other. The current review therefore tried to address these issues for use of ANS in Indian prospective in light of recent emerging evidence. Due to better safety profile, lesser side effects, lower cost, and easy storage, we recommend dexamethasone as a steroid of choice for antenatal prophylaxis.
