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: Coronary artery disease (CAD) has known risk factors. Individual risks related to specific ethnicities are complex and depend on genetic predisposition and lifestyle.

Objectives: To compare the nature and prevalence of risk factors in Arab and non-Arab ethnic patients with symptomatic obstructive CAD referred for coronary angiography.

Methods: CAD, defined as coronary angiography with a ≥ 50% narrowing in ≥ 1 vessel, was diagnosed in 1029 patients admitted to a medical center between April 2014 and October 2015. Patients were divided into two groups according to ethnic origin: Arab vs. non-Arab. Demographics, clinical presentation, and coronary risk profiles were compared.

Results: The diagnosis of CAD was made during ST-elevation myocardial infarction (STEMI) in 198 patients (19%) who arrived at the clinic, 620 (60%) with unstable angina/non-STEMI, and 211 (21%) with stable angina. Patients with symptomatic CAD and Arab ethnicity were 47% more prevalent than non-Arab patients presenting with CAD. The Arab patients were appoximately 5 years younger, 50% more likely to be active smokers, 25% more likely to be obese, and more likely to have a family history of CAD. Other coronary risk factors were similar between the two groups.

Conclusions: Smoking and obesity, which are potentially modifiable CAD risk factors, stood out as major risk factors, in addition to genetic disposition, among Arab and non-Arab patients with symptomatic CAD. Screening and educational interventions for smoking cessation, obesity control, and compliance to treatment of co-morbidities should be attempted in order to decrease CAD in the Arab population.

Background:  After the introduction of endoscopic techniques to other surgical fields, like general surgery, gynecology and thoracic surgery, cardiac surgeons sought their own methods of using minimally invasive techniques.

Objectives:  To examine whether this approach is less invasive and yields better results, more desirable cosmetic results, and a more rapid and complete rehabilitation, maintaining safety, efficacy, and outcome equivalent to those of more established procedures, such as median sternotomy.

Methods:  From January 2000 to July 2001, 22 patients underwent video-assisted port-access mitral or aortic valve repair or replacement with the Heartport system in our department, and one underwent closure of atrial septal defect.

Results:  Intraoperative transesophageal echocardiography revealed excellent functional results. Total operating room time, perfusion time, and cross-clamp time in this technique decreased with our growing experience, and remains stable. There were no intraoperative reversals to mid-steronomy, no mortalities, and only one complication 24 hours after surgery.

Conclusions:  Thoracoscopic assisted cardiac surgery (via port access) provides all the advantages of minimally invasive surgery, accelerates recovery, decreases pain, and maintains overall surgical efficacy, while avoiding the complications and pathology of mid-sternotomy.  For appropriate patients, this is the method of choice in our department.
