Atrial Tachyarrhythmias

Background: Catheter ablation has become a well-established indication for long-term rhythm control in atrial fibrillation (AF) patients refractory to anti-arrhythmic drugs (AADs). Efficacy and safety of AF catheter ablation (AFCA) before AADs failure are, instead, questioned.Objective: The aim of the study was to perform a systematic review and meta-analysis of randomized clinical trials (RCTs) comparing first-line AFCA with AADs in symptomatic patients with paroxysmal AF.Methods: We performed a random-effects meta-analysis of binary outcome events comparing AFCA with AADs in rhythm control-naïve patients. The primary outcomes, also stratified by the type of ablation energy (radiofrequency or cryoenergy), were (1) recurrence of atrial tachyarrhythmias and (2) recurrence of symptomatic atrial tachyarrhythmias. The secondary outcomes included adverse events.Results: Six RCTs were included in the analysis. AFCA was associated with lower recurrences of atrial tachyarrhythmias [relative risk (RR) 0.58, 95% confidence interval (CI) 0.46–0.72], consistent across the two types of ablation energy (radiofrequency, RR 0.50, 95% CI 0.28–0.89; cryoenergy, RR 0.60, 95% CI 0.50–0.72; p-value for subgroup differences: 0.55). Similarly, AFCA was related to less symptomatic arrhythmic recurrences (RR 0.46, 95% CI 0.27–0.79). Overall, adverse events did not differ. A trend toward increased periprocedural cardiac tamponade or phrenic nerve palsy was observed in the AFCA group, while more atrial flutter episodes with 1:1 atrioventricular conduction and syncopal events were reported in the AAD group.Conclusions: First-line rhythm control therapy with AFCA, independent from the adopted energy source (radiofrequency or cryoenergy), reduces long-term arrhythmic recurrences in patients with symptomatic paroxysmal AF compared with AADs.

Background: Although, some clinical trials investigated the maternal and neonatal effect of fentanyl as a premedication before induction of general anesthesia in cesarean section, to the best of our knowledge, there is no systematic review to summarize these results. Objectives: The present systematic review and meta-analysis evaluated the maternal and neonatal effect of intravenous fentanyl as a premedication before induction of general anesthesia in cesarean section. Methods: The databases of Pubmed, Embase, Scopus and Cochrane library were searched till July 2017 to identify randomized clinical trials which evaluated the effects of intravenous fentanyl as a premedication before induction of general anesthesia compared with placebo on neonate first and fifth minute Apgar score and maternal heart rate and mean arterial pressure (MAP) in cesarean section. Standard Mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis. Results: The present systematic review and meta-analysis consisted of three clinical trials including 180 women in labor. Considering the results of meta-analysis, there is no significant differences between fentanyl and placebo in the case of Apgar score at 1 minute; however, the Apgar score of 5 minutes was significantly lower in fentanyl group compared with placebo (SMD -0.68, 95%CI: - 0.98, -0.38, p<0.001). In the term of maternal hemodynamics, the heart rate (SMD -0.43, 95%CI: - 0.72, -0.13, p=0.004) and MAP (SMD -0.78, 95% CI: -1.09, -0.48, p<0.001) in fentanyl group were significantly lower compared with placebo group. Conclusion: The present meta-analysis showed that using intravenous fentanyl as a premedication before induction of general anesthesia had adverse effects on neonate Apgar score. However, it had positive effects on preventing adverse consequences of intubation on maternal hemodynamics.
