Abstract
Abstract
Background/Introduction
Abbreviation of duration of dual antiplatelet therapy (DAPT) (one or three months) has been recently proposed, especially for high-bleeding risk patients, after percutaneous coronary intervention (PCI) with drug-eluting stent (DES).
Purpose
The purpose of the specific systematic review and meta-analysis was to compare 30-days versus longer duration (≥3 months) of DAPT in patients undergoing PCI with DES, focusing on ischemic and bleeding events.
Methods
Three databases were screened for eligible randomized-control trials. The primary endpoint was the incidence of net adverse clinical events (NACE), as they were defined in each trial. Secondary endpoints consisted of major adverse cardiovascular events (MACE), all-cause and cardiovascular mortality, myocardial infraction, stroke, stent-thrombosis, repeat revascularization and major bleeding.
Results
We included 4 RCTs with a total of 26,576 patients; 13,282 patients were grouped in 30-days DAPT, while the remaining 13,294 were allocated in longer period of DAPT. One-month of DAPT did not significantly reduce NACE (odds ratio [OR]: 0.87, 95% confidence intervals [Cl]: 0.74–1.03); however major bleedings were significantly reduced by 22% (OR: 0.78, 95% Cl: 0.65–0.94). Mortality or ischemic events (stroke, myocardial infraction, revascularization and stent thrombosis) were not affected.
Conclusions
Thirty-days DAPT did not significantly affect NACEs. However, odds of major bleedings were reduced significantly by 22%. Mortality and ischemic events did not differ between the two arms. Thus, 30-days DAPT could be considered as a safe and feasible after PCI with DES in selected patients, especially those in high-bleeding risk. Forthcoming RCTs could shed light on the optimal duration of DAPT.

Abstract
Abstract
Background
Recently, the concept of left bundle branch pacing (LBBP) has emerged in clinical practice, in an attempt to prevent the deteriorating effects of right ventricular pacing (Vp).
Purpose
The aim of this study is to compare the effect of Vp on left ventricular (LV) dyssynchrony in patients with atrioventricular block (AVB) and preserved ejection fraction (EF), subjected to either LBBP or right ventricular septal pacing (RVSP).
Methods
Patients with AVB are randomized 1:1 to LBBP or RVSP. The effect of Vp is evaluated by echocardiographic indices of dyssynchrony, such as global myocardial work efficiency (GWE) and peak systolic dispersion (PSD). GWE represents the ratio of constructive work divided by the sum of constructive and wasted work [1]. Successful LBBP is defined by the presence of right bundle branch block paced QRS morphology in lead V1 and stim to LV activation time <75 msec [2]. No back-up right Vp lead was used in LBBP group.
Results
We conducted a preliminary analysis of the first 20 patients. Enrollment is still ongoing and total follow-up period is one year. We sought to investigate the acute effect of Vp on LV dyssynchrony 24 hours post procedure. Patients' baseline characteristics were similar in both groups and are presented in Table 1.
One crossover was noted from LBBP to RVSP group, due to high ventricular capture threshold during implant. Implantation time was increased in LBBP arm (130±17.4 min in LBBP versus 47.7±4.5 min in RVSP group, p=0.004). Left bundle branch potential was recorded in 3 out of 10 LBBP patients. No statistically significant difference was demonstrated in GWE between the two groups (91.3% in LBBP versus 87.4% in RVSP group, p=0.052). PSD was numerically shorter in LBBP (53.3 msec) versus in RVSP (63.6 msec), p=0.114. There were no complications during both the acute perioperative phase and the running period of the follow-up. Moreover, no acute ventricular threshold capture rise, or lead dislodgement has been observed in neither group.
The increased implantation time may be attributed to the more demanding technique, or the learning curve period required in the arm of LBBP. In the present analysis, a remarkable difference regarding GWE in favor of the LBBP group was demonstrated, although statistically not significant. However, even in this initial phase of the study, there is a trend of better LV synchrony and less wasted myocardial work in the LBBP group. The final difference of these indices will be assessed at the end of the one-year follow-up, when comparative results will be available.
Conclusion
LBBP is a novel, safe pacing method. Despite the longer procedural time and the risk of crossover, LBBP seems to offer better – without however statistical significance – LV synchrony even in the acute postoperative phase compared to RVSP. Longer follow-up studies are required to test whether LBBP compared to RVSP confers substantial clinical benefit.

Abstract
OBJECTIVE To define the prevalence of infection with hepatitis B virus (HBV) and hepatitis C virus (HBC), and the modifications observed during the last 8 years, amongst parturients who gave birth in our department. DESIGN This was a retrospective study. PATIENTS The 5497 parturients who gave birth in our department between October 1994 and September 2002. RESULTS On average, 3.87% (213) of the pregnant women tested positive for hepatitis B surface antigen; 2.90% amongst pregnant Greek women and 4.67% amongst pregnant immigrant women. Among all pregnant women, 0.80% (44) tested positive for antibodies against HCV; 0.16% amongst Greek women and 1.33% amongst immigrant women. CONCLUSIONS HBV prevalence in pregnant women did not seem to be affected by the increase of immigrants in our obstetric population over the course of time. HCV prevalence in the pregnant women, however, did seem to follow the increase of immigrants in our obstetric population. Economic and security issues unfortunately deprive some neonates, born to mothers with HBV infection, from the use of hepatitis B immunoglobulin.
