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: Peripartum cardiomyopathy (PPCM) is a rare but potentially devastating complication of pregnancy. Although the pathophysiology of PPCM is not fully understood, there are known risk factors for developing PPCM, which are maternal and gestation related. In the first wave of the coronavirus disease 2019 (COVID-19) pandemic, we witnessed an elevated incidence of PPCM among COVID-19 survivors.

Objectives: To present a single-center case series of three patients diagnosed with peripartum cardiomyopathy after recovered from COVID-19 during the index pregnancy.

Methods: In this single center case study, all patients diagnosed with PPCM at our institute during the examined time frame were included. Electronic medical records were studied.

Results: Three patients previously diagnosed with asymptomatic or mildly symptomatic COVID-19 disease during pregnancy presented with PPCM before or shortly after delivery. Patients underwent testing to rule out residual COVID-19 myocarditis, were treated pharmacologically and with wearable defibrillators as needed, and were examined in follow-up 1–9 months after delivery.

Conclusions: Residual endothelial damage due to COVID-19 disease, even if originally mild in presentation, could predispose pregnant patients to PPCM and should be considered as a risk factor when assessing patients with new onset symptoms of heart failure. Further research is needed to confirm this hypothesis and fully determine the underlying pathophysiology. These preliminary findings warrant a high index of suspicion for PPCM in COVID-19 recoverers.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease caused by chronic obstruction of major pulmonary arteries, which can be cured by pulmonary endarterectomy. However, many CTEPH patients are not surgical candidates. Balloon pulmonary angioplasty (BPA) is an emerging technique used to treat inoperable CTEPH.

Objectives: To describe the first Israeli experience with BPA for inoperable CTEPH.

Methods: In 2017 we established a BPA program at our institution. We reviewed the outcomes to date of BPA in our center.

Results: Forty-seven BPA procedures were performed in five patients with inoperable CTEPH (4–17 procedures/patient). Mean pulmonary artery pressure improved in all patients (median decrease 17 mmHg, range 10–26 mmHg). Pulmonary vascular resistance also improved (median decrease 11 Woods Units/m², range 8–16 Woods Units/m²). Cardiac output increased in 4 of 5 patients and decreased in one. Functional capacity improved from New York Heart Association (NYHA) III to II in four patients; one patient was NYHA II at baseline without change after BPA. Six-minute walking distance improved by a median of 97 meters. (range 21–197 meters). Hemodynamic and functional improvements were sustained at follow-up 5–11 months after the last BPA procedure. BPA enabled 2 of 3 patients treated with parenteral prostanoids to be switched to oral therapy. There were no major complications.

Conclusions: We successfully established BPA as a treatment for inoperable CTEPH in our center. BPA resulted in hemodynamic and clinical improvements that were sustained over time.

Background: Admission to an intensive care unit (ICU) is an objective marker of severe maternal morbidity (SMM).

Objectives: To determine the prevalence of obstetric ICU admissions in one medical center in Israel and to characterize this population.

Methods: In this retrospective study the files of women coded for pregnancy, birth, or the perinatal period and admission to the ICU were pulled for data extraction (2005–2013).

Results: During the study period, 111 women were admitted to the ICU among 120,279 women who delivered babies (0.09%). Their average age was 30 ± 6 years, most were multigravida, a few had undergone fertility treatments, and only 27% had complicated previous pregnancies. Most pregnancies (71.2%) were uneventful prior to admission. ICU admissions were divided equally between direct (usually hemorrhage) and indirect (usually cardiac disease) obstetric causes.

Conclusions: The indications for obstetrics ICU admission correlated with the proximate causes of maternal arrest observed worldwide. While obstetric hemorrhage is often unpredictable, deterioration of heart disease is foreseeable. Attention should be directed specifically toward improving the diagnosis and treatment of maternal heart disease during pregnancy in Israel.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease, which is caused by chronic obstruction of major pulmonary arteries. CTEPH can be cured by pulmonary endarterectomy (PEA). PEA for CTEPH is a challenging procedure, and patient selection and the perioperative management are complex, requiring significant experience.

Objectives: To describe the establishment of a national CTEPH–PEA center in Israel and present results of surgery.

Methods: In this study, we reviewed the outcomes of PEA in a national referral, multi-disciplinary center for CTEPH–PEA. The center was established by collaborating with a high-volume center in Europe. A multidisciplinary team from our hospital (pulmonary hypertension specialist, cardiac surgeon, cardiac anesthesiologist and cardiac surgery intensivist was trained under the guidance of an experienced team from the European center.

Results: A total of 38 PEA procedures were performed between 2008 and 2018. We included 28 cases in this analysis for which long-term follow-up data were available. There were two hospital deaths (7%). At follow-up, median New York Heart Association (NYHA) class improved from III to I (P < 0.0001), median systolic pulmonary pressure decreased from 64 mmHg to 26 mmHg (P < 0.0001), and significant improvements were seen in right ventricular function and exercise capacity.

Conclusions: A national center for performance of a rare and complex surgical procedure can be successfully established by collaboration with a high-volume center and by training a dedicated multidisciplinary team.

Background: Clinical research is needed to identify patients with axial spondyloarthritis (axSpA) who are more likely to be responsive to interleukin (IL)-17 inhibition.

Objectives: To evaluate short-term efficacy of secukinumab in the management of axSpA.

Method: Twenty-one patients (7 males, 14 females) with axSpA were consecutively treated with secukinumab. Laboratory and clinical assessments were based on erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Ankylosing Spondylitis Disease Activity Score (ASDAS)-CRP, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Data were recorded at baseline and at a 3 month follow-up visit.

Results: The study was comprised of 21 patients. Both BASDAI and ASDAS-CRP showed a statistically significant reduction between the baseline and the 3 month visit (P < 0.0001 and P = 0.0005, respectively). During the laboratory assessment, ESR showed a significant decrease (P = 0.008) while CRP improvement did not reach statistical significance (P = 0.213). No statistical significance was observed between patients treated with secukinumab 150 mg vs. 300 mg in BASDAI (P=0.99), ASDAS-CRP (P = 0.69), ESR (P = 0.54), and CRP (P = 0.56). No significant differences emerged between the BASDAI (P = 0.15), ASDAS-CRP (P = 0.09), and CRP (P = 0.15) rates in biologic-naïve patients and those previously failing tumor necrosis factor-α inhibition. Conversely, ESR decrease was significantly higher in the biologic-naïve subgroup (P = 0.01). No adverse events were reported.

Conclusions: Secukinumab has proven remarkable short-term effectiveness, regardless of the biologic treatment line. A dosage of 150 mg proved to be appropriate in the clinical and laboratory management of axSpA.

Objectives: To use pelvic fractures as a test case for the efficiency of the Israeli trauma system, as reflected in the experience of our medical center.

Methods: Data were obtained from the medical charts of all cases of pelvic fractures admitted to our medical center between 1987 and 1999. We obtained demographic data, information on the cause of injury, fracture classification, co-injuries and Injury Severity Score, treatment strategies, and mortality rate.

Results: Altogether, 808 patients with pelvic injuries were treated in our medical center. The most common cause of injury was motor vehicle accidents (51%). Pelvic fractures without acetabular involvement were diagnosed in 58% of patients and isolated acetabular fractures in 32%, while 10% sustained combined injuries to the pelvic ring and the acetabulum. The overall rate of operative stabilization was 34%. The majority of patients had associated injuries, mostly additional musculoskeletal injuries. Altogether, 13% were referred from Level II/III trauma centers. We observed an increase in the total number of local admissions, in the percentage of referred patients and in the percentage of operated patients during the study period. The observed mortality rate was 5%.

Conclusions: Our results show a more than twofold increase in the percentage of referred patients following the designation of a Level I trauma center. These referrals result not only from the designation as a Level I trauma center, but also from the presence of a dedicated team of pelvic fracture specialists, available 24 hours a day. In addition, a larger percentage of patients undergo surgery for internal fixation of pelvic fractures, in accordance with current worldwide trends.
