Background: Cardiac implantable electronic devices (CIEDs) are increasingly being used; thus, there is an increasing need for transvenous lead extraction (TLE).

Objectives: To summarize our experience with TLE at single referral center in northern Israel.

Methods: The study included all patients who underwent TLE at our center between 2019 and 2022, regardless of the indication.

Results: The cohort included 50 patients. The mean age was 69 ± 10.36 years; 78% were males. A total of 99 electrodes were targeted. The mean number of electrodes was 1.96 (range 1–4) per patient. The time between lead implantation and extraction ranged between 1.1 and 34 years with an average of 8.14 ± 5.71 years (median of 7.5 years). Complete lead removal was achieved in 98% of patients and in 98.99% of leads. The complete procedural success rate as well as the clinical procedural success rate was 96%. The procedural failure rate was 4% (1 patient died 2 days after the index procedure and 1 patient remained with large portion of lead). The indication for TLE was infection in 78% of the cohort group. Powered mechanical sheaths were used in 36 patients (72%), laser sheaths in 27 (54%), and a combination of laser and mechanical sheaths in 16 (32%).

Conclusions: The clinical and procedural success rates of TLE, primarily for CEID-related infection, were high. A combination of laser and mechanical sheaths was needed in one-third of patients.

Background: Pacemaker pocket early post-implantation inflammation (EPII) is defined as clinical signs of local erythema without any systemic signs of infection occurring early after implantation. Data on the best treatment regimen for apparent superficial EPII is scarce. 

Objectives: To investigate the prognostic value of medical treatment, rather than extraction surgery, in patients with EPII. 

Methods: Data from 6013 consecutive patients who underwent cardiac implantable electronic device (CIED) implantation or replacement from 2007–2015 were retrospectively analyzed; 40 (0.7%) presented with EPII. Our goal was the absence of major complications and to avoidance of extraction. 

Results: Patients with EPII were initially treated medically. Nineteen (47%) (group A) recovered with antibiotic treatment only. In the other 21 patients (53%) (group B), CIED extraction was performed. Group B had more major complications compared to group A (15 [71%] vs. 0 [0%], P < 0.001). The only significant difference in baseline characteristics was history of non-initial procedure. While 86% of group B patients had a previous non-initial procedure, only 53% of group A patients underwent previous replacement (P < 0.05). In multivariate analysis, previous non-initial procedure was the only predictor for need of extraction at 1 year, hazard ratio 3.5, 95% confidence interval 1.001–11.73, P < 0.05.

Conclusions: Conservative treatment in patients with EPII after non-initial procedure can lead to serious adverse events resulting in the need for extraction. Close follow-up and aggressive treatment should be considered early in the therapeutic course.

Background: Transvenous lead extraction can lead to tricuspid valve damage. 

Objectives: To assess the incidence, risk factors and clinical outcome of tricuspid regurgitation (TR) following lead extraction.

Methods: We prospectively collected data on patients who underwent lead extraction at the Sheba Medical Center prior to laser use (i.e., before 2012). Echocardiography results before and following the procedure were used to confirm TR worsening, defined as an echocardiographic increase of at least one TR grade. Various clinical and echocardiographic parameters were analyzed as risk factors for TR. Clinical and echocardiographic follow-up was conducted to assess the clinical significance outcome of extraction-induced TR.

Results: Of 152 patients who underwent lead extraction without laser before 2012, 86 (56%) (192 electrodes) had echocardiography results before and within one week following the procedure. New or worsening TR was discovered in 13 patients (15%). Use of mechanical tools and younger age at extraction were found on multivariate analysis to be factors for TR development (P = 0.04 and P = 0.03 respectively). Average follow-up was 22.25 ± 21.34 months (range 8–93). There were no significant differences in the incidence of right-sided heart failure (50% vs. 23%, P = 0.192) or hospitalizations due to heart failure exacerbations (37.5% vs. 11%, P = 0.110). No patient required tricuspid valve repair or replacement. Death rates were similar in the TR and non-TR groups (20% vs. 33%).

Conclusions: TR following lead extraction is not uncommon but does not seem to affect survival or outcomes such as need for valve surgery. Its long-term effects remain to be determined.

Background: Cataract extraction is the most commonly performed ophthalmic surgical procedure. There is no registry for documenting cataract surgical procedures and the overall risk of its complications over time in Israel.


Objectives: To present trends in the number and type of selected parameters associated with cataract surgical procedures in Israel between 1990 and 2014.


Methods: Questionnaires had been sent annually to all surgical centers in which cataract surgery was performed in Israel during the study period. The trends that were investigated included annual rates, surgical sites, surgical techniques, use of an intraocular lens (IOL) and type and rates of postoperative endophthalmitis (POE). 


Results: A total of 812,112 cataract surgical procedures were reported during the 25 year study period. Responses to the questionnaire increased from 75% in 1990 to 100% in 2006 onwards. The annual number of reported cataract surgical procedures increased from 16,841 (3.5 per 1000) in 1990 to 57,419 in 2014 (6.9 per 1000), representing an increase of 197%. There was a shift from performing the surgery in the public health system to private medical centers. The surgical technique changed from predominantly manual extracapsular cataract extraction (56% in 1999) to predominantly phacoemulsification (98.7% in 2014). POE rates decreased from 0.25% in 2002 to 0.028% in 2014. 


Conclusions: There was a continuous increase in the rate of surgical cataract procedures, and more were performed in private medical facilities. There was also a major shift towards advanced cataract procedures and a decreased rate of POE.

Background: Even operative deliveries defined as “urgent” show marked diurnal variation with a significant increase during regular working hours.

Objective: To investigate the diurnal variation of urgent operative deliveries and its potential implications on the outcome of newborns.

Methods: We conducted a retrospective study of all deliveries in a public hospital from 1 January 1990 to 31 December 1998. Delivery mode variables analyzed were spontaneous vaginal delivery, urgent cesarean section and operative vaginal delivery. Deliveries were stratified hourly throughout the day. The rate of operative deliveries was calculated and the analysis was then performed according to the daily routine shifts of the medical staff. Birth weight and Apgar scores at 1 and 5 minutes were retrieved as outcome measures.

Results: The rate of urgent cesarean deliveries increased significantly between 8 a.m. and 2 p.m. (150%–230%) from that predicted. The lowest rate of urgent cesarean sections was found between 5 a.m. and 6 a.m. (5.3%). Mean birth weight in spontaneous deliveries was higher in the morning hours than during the night shift (3,293 ± 520 g vs. 3,277 ± 510 g, respectively, P < 0.005). Apgar scores of newborns delivered by urgent cesarean section during the morning were higher compared to those delivered during night shifts and the rate of low Apgar scores was lower in the morning than in evening and night shifts.

Conclusions: Our results indicate a marked diurnal variation in urgent operative deliveries, caused perhaps by varying definition of “urgency” according to the time of day.
