There has been increased rate of cardiac implantable electronic devices (CIED) implanted worldwide. Respectively the numbers of patients with absolute indications for lead extraction (pacemaker and ICD) grow up exponentially. The aim of our study is to present the initial experience and long-term results of pacemaker and ICD lead extraction in patients treated in Cardiology department of University hospital “Sveta Anna” Sofi a. Material and Methods: Retrospective study was performed of patients with CIED implanted greater than 1 year and indications for lead extraction. Clinical and procedural characteristics, success rate, complications rate, and reinfection rate data were collected and analyzed. Results: In the period August 2016 to May 2021, a total of 54 patients were admitted to our department with an absolute indication for lead extraction. A total of 114 pacemakers and ICD electrodes were extracted during 54 procedures. In 47 patients (87%) was shown complete technical success with removal of all hardware and in 53 patients (98.1%) clinical success of the procedure was found. The incidence of major periprocedural complications requiring urgent cardiac surgery in our series was 2 (3.7%). Follow-up revealed a very low recurrence infection rate – only 1 patient (1.9%). Conclusion: Lead extraction is a safe and effective procedure. The establishment of a specialized center with an organized system for lead extraction is key in achieving excellent short- and long-term results.

Background: Transvenous lead extraction (TLE) is the preferred management strategy for complications related to cardiac implantable electronic devices. TLE sometimes can cause serious complications. Methods: Outcomes of TLE procedures using non-powered mechanical sheaths were analyzed in 1500 patients (mean age 68.11 years; 39.86% females) admitted to two high-volume centers. Results: Complete procedural success was achieved in 96.13% of patients; clinical success in 98.93%, no periprocedural death occurred. Mean lead dwell time in the study population was 112.1 months. Minor complications developed in 115 (7.65%), major complications in 33 (2.20%) patients. The most frequent minor complications were tricuspid valve damage (TVD) (3.20%) and pericardial effusion that did not necessitate immediate intervention (1.33%). The most common major complication was cardiac laceration/vascular tear (1.40%) followed by an increase in TVD by two or three grades to grade 4 (0.80%). Conclusions: Despite the long implant duration (112.1 months) satisfying results without procedure-related death can be obtained using mechanical tools. Lead remnants or severe tricuspid regurgitation was the principal cause of lack of clinical and procedural success. Worsening TR(Tricuspid regurgitation) (due to its long-term consequences), but not cardiac/vascular wall damage; is still the biggest TLE-related problem; when non-powered mechanical sheaths are used as first-line tools.

Background: Advances in stent technology have widened the field of indications for stent treatment of femoro-popliteal artery lesions, however the use of stents in bending arterial segments is restricted because some first- and second-generation nitinol stent designs did not respond well to the mechanical forces of femoro-popliteal segments in motion which pose a substantial risk of stent fracture inducing in-stent-stenosis. New generation nitinol stents are supposed to overcome these limitations but long-term results are rare. Patients and methods: In forty-five patients (mean age 68 y, range 50 - 85) with peripheral arterial disease (TASC II A-C, Rutherford category 2 - 5) forty-six lesions of the superficial femoral artery (37) or popliteal artery (9) were treated [25 high-grade stenoses, mean length 53 mm (range 30 - 145 mm); 21 chronic total occlusions, mean length 74 mm (range 30 - 180 mm)]. 74 % of lesions were located in the mobile bending arterial segments in the distal femoral or the popliteal segment. Clinical reevaluation performed at discharge, at 6, 12, 24, and 36 months included at least the measurement of ankle-brachial index (ABI) and duplex sonography. Results: Procedural success rate was 100 %. At 6, 12, 24, and 36 months, cumulative primary patency rate was 93.5 %, 84.8 %, 80.5 %, and 74.3 % (SE<10); freedom from target lesion revascularization rate was 95.7 %, 89.2 %, 84.9 %, and 79.3 % (SE<10); Rutherford category and ABI improved in all patients and clinical success was maintained in more than 85 % of patients. Conclusions: Sustained technical and clinical success and good clinical long-term results were achieved with Misago™ nitinol stent implantation in femoro-popliteal lesions with moderate risk for in-stent-stenosis, and in the distal femoral and popliteal mobile segment.

Purpose: To evaluate the long term visual, refractive, and corneal tomographic outcomes of epithelium-off accelerated corneal collagen cross-linking (ACXL) in the management of pediatric keratoconus (KC). Methods: This retrospective study included patients under 18 years old with progressive KC who underwent ACXL between 2012 and 2019 at Dicle University Hospital. Complete ophthalmic examination was performed including uncorrected distance visual acuity (UDVA), best spectacle-corrected distance visual acuity (CDVA), manifest refraction, and corneal tomography. Evaluations were performed preoperatively and at 6 months intervals postoperatively. Results: Forty-nine eyes of 49 patients were included in the study. The mean age of patients at the time of ACXL was 14.2 ± 1.8 (range: 9.5–17.3) years. Mean follow up was 4.61 ± 1.90 (range: 2.0–8.1) years. The mean LogMAR UDVA improved from 0.94 ± 0.41 to 0.81 ± 0.43, 0.69 ± 0.41, and 0.67 ± 0.33 after 1, 3, and 5 years respectively ( p = 0.001). The mean LogMAR CDVA improved from 0.58 ± 0.36 to 0.46 ± 0.31, 0.34 ± 0.23, and 0.39 ± 0.27 after 1, 3, and 5 years respectively ( p = 0.015). The mean refractive cylinder improved significantly from 6.01 ± 2.07 diopters (D) to 5.46 ± 1.87, 5.38 ± 2.18, and 5.02 ± 2.31 D after 1, 3, and 5 years respectively ( p = 0.005). As compared to preoperative values, steep keratometry and maximum keratometry were not significantly different ( p = 0.805 and 0.448, respectively) following ACXL, while flat keratometry significantly improved after ACXL ( p = 0.012). Although central corneal thicknesses decreased significantly ( p = 0.029), the decrease in thinnest corneal thickness was not statistically significant ( p = 0.205). Conclusion: Epithelium-off ACXL seems to be effective for halting KC progression with long term clinical benefits in pediatric patients.

Summary At our hospital, the main treatment for resectable esophageal cancer (EC) has since 2013 been total minimally invasive esophagectomy (TMIE). The aim of this study was to present the short- and long-term results in patients operated with TMIE. This cross-sectional study includes all patients scheduled for TMIE from June 2013 to January 2016 at Oslo University Hospital. Data on morbidity, mortality, and survival were retrospectively collected from the patient administration system and the Norwegian Cause of Death Registry. Long-term postoperative health-related quality of life (HRQL) and level of dysphagia were assessed by patients completing the following questionaries: EORTC QLQ-OG25, QLQ-C30, and the Ogilvie grading scale. A total of 123 patients were included in this study with a median follow-up time of 58 months (1–88 months). 85% had adenocarcinoma, 15% squamous cell carcinoma. Seventeen patients (14%) had T1N0M0, 68 (55%) T2-T3N0M0, or T1-T2N1M0 and 38 (31%) had either T3N1M0 or T4anyNM0. Ninety-eight patients (80%) received neoadjuvant (radio)chemotherapy and 104 (85%) had R0 resection. Anastomotic leak rate and 90-days mortality were 14% and 2%, respectively. The 5-year overall survival was 53%. Patients with tumor free resection margins of &gt;1 mm (R0) had a 5-year survival of 57%. Median 60 months (range 49–80) postoperatively the main symptoms reducing HRQL were anxiety, chough, insomnia, and reflux. Median Ogilvie score was 0 (0–1). In this study, we report relatively low mortality and good overall survival after TMIE for EC. Moreover, key symptoms reducing long-term HRQL were identified.

Abstracts Introduction Pancreatic fluid collection (PFC) is a common complication of acute pancreatitis. Endoscopic ultrasound (EUS)-guided drainage, which is often followed by direct endoscopic necrosectomy (DEN), has become the primary approach to treat PFC, including pancreatic pseudocysts (PP) and walled-off necrosis (WON). We aimed to determine retrospectively the short- and long-term results of patients treated in our endoscopy unit and to identify parameters that are associated with treatment efficacy and outcome. Methods The data of 41 consecutive patients with post-pancreatitic PFC, who underwent endoscopic transmural intervention between 2014 and 2016, were analyzed retrospectively. After an initial EUS-guided puncture, one or more plastic stents were placed and DEN was performed if necrotic tissue remained. Results The mean diameter of the PFC was 74.0 ± 4.8 mm. Of the PFCs, 29.3% were classified as PP and 70.7% as WON. Altogether, 196 transmural endoscopic procedures were performed, including 73 endoscopic necrosectomies in a subgroup of 21 patients (20 WON, 1 PP). Initial technical success was achieved in 97.6% of patients and the short-term clinical success rate was 90.2%. The long-term clinical success rate was 82.9%, since four patients died from septic shock and/or multiple organ failure and three patients developed recurrent PFC some months after the initial discharge from endoscopic treatment. Procedural complications were registered in 9 patients during 10 of 196 endoscopic procedures (5.1%): bleeding (6), cardiorespiratory insufficiency (2), perforation with pneumoperitoneum (1), aspiration with respiratory insufficiency (1), and non-perforating superficial damage of the gastric wall (1). Neither the size of the PFC nor the initial value of C-reactive protein (CRP) or other biochemical markers were correlated with efficacy or outcome of treatment. Only the cumulative number of days with CRP > 50 mg/L significantly correlated with the number of follow-up endoscopic sessions and DEN. Fungal colonization of PFC correlated significantly (p < 0.05) with the risk of mortality (44% vs. 0%), need for intensive care treatment (66.7% vs. 25%), and sepsis (55.6% vs. 12.5%). Conclusions We confirm that EUS-guided drainage followed by DEN in patients with solid necrotic material is an effective and relatively safe therapeutic approach. Prolonged elevation of CRP and fungal colonisation of the PFC are associated with a worse course of the disease.

Background and Objectives: Over the last five decades cardiac implantable electronic devices (CIED) have become established as the mainstay for the treatment of permanent bradycardias, chronic heart failure and dangerous heart rhythm disturbances. These devices improve survival and quality of life in many patients. However, infections associated with CIED implantation, particularly lead-related infective endocarditis (LRIE), can offset all benefits and make more harm than good for the patient. To date, there are no other studies in Latvia, addressing patients with lead-related infective endocarditis. The objective of this study was to identify the most common pathogens associated with LRIE and their antimicrobial resistance and to identify possible risk factors of patients who present with LRIE. Materials and Methods: The study was performed retrospectively at Pauls Stradins Clinical University Hospital (PSCUH). The study included patients who were referred to PSCUH due to LRIE for lead extraction. Patients were identified from procedural journals. Information about isolated microorganisms, patient comorbidities and visual diagnostics data was taken from patient records. Results: Forty-nine patients with CIED related infective endocarditis were included in the study, 34 (69.4%) were male, median age of all patients was 65.0 (50.5–73.0) years, median hospital stay was 15.5 (22.0–30.5) days. Successful and complete lead extraction was achieved in all patients. Thirty-two (65.3%) had received antibiotics prior to blood sample. Only in 31 (63.3%) positive culture results were seen. The most common isolated pathogens were Staphylococcus aureus (23.5%) and coagulase negative staphylococci (23.5%). Other bacteria were isolated considerably less often. The atrial lead was most common location for lead vegetations, seen in 50.0% of cases. Five (10.2%) patients have died due to the disease. Conclusions: Lead-related infective endocarditis is a major complication of cardiac implantable electronic devices with considerable morbidity and mortality, which in our study was as high as 10.2%.

Abstract Aims  Commonly, a dysfunctional defibrillator lead is abandoned and a new lead is implanted. Long-term follow-up data on abandoned leads are sparse. We aimed to investigate the incidence and reasons for extraction of abandoned defibrillator leads in a nationwide cohort and to describe extraction procedure-related complications. Methods and results  All abandoned transvenous defibrillator leads were identified in the Danish Pacemaker and ICD Register from 1991 to 2019. The event-free survival of abandoned defibrillator leads was studied, and medical records of patients with interventions on abandoned defibrillator leads were audited for procedure-related data. We identified 740 abandoned defibrillator leads. Meantime from implantation to abandonment was 7.2 ± 3.8 years with mean patient age at abandonment of 66.5 ± 13.7 years. During a mean follow-up after abandonment of 4.4 ± 3.1 years, 65 (8.8%) abandoned defibrillator leads were extracted. Most frequent reason for extraction was infection (pocket and systemic) in 41 (63%) patients. Procedural outcome after lead extraction was clinical success in 63 (97%) patients. Minor complications occurred in 3 (5%) patients, and major complications in 1 (2%) patient. No patient died from complication to the procedure during 30-day follow-up after extraction. Conclusion  More than 90% of abandoned defibrillator leads do not need to be extracted during long-term follow-up. The most common indication for extraction is infection. Abandoned defibrillator leads can be extracted with high clinical success rate and low risk of major complications at high-volume centres.

Background: Long term results of systemic lysis therapy with ultrahigh-dose urokinase (UHUK) in reopening aorto-iliac occlusive disease have not yet been evaluated. This prospective trial investigates the long-term primary patency rate, the rate of complications and assesses the role of different expected influence parameters on the primary patency rate. Patients and methods: 72 patients with aorto-iliac occlusive disease received daily intravenous infusions of UHUK either until reperfusion or – after at least 3 cycles – no progress in recanalization could be stated on two consecutive days by duplex scanning. Results: Systemic lysis therapy was morphological at least partially successful in 44 patients (61.1%). Concomitant percutaneous transluminal angioplasty was performed in 41 patients (56.9%), surgery in 7 patients (9.7%) and both in further 5 patients (6.9%). In patients without surgery hemodynamical success could be achieved in 39 patients (54.2%) and even more important clinical success in 51 patients (70.8%). Compared to baseline results patients improved significantly in ankle/brachial pressure index and in Fontaine stages (p < 0,001), the same results could be seen after a mean follow-up period of 62 months. Thrombolysis was complicated in 4 patients (5.6%) by macroembolizations but no major bleedings or deaths occurred. Primary patency was 76%, 64%, and 43% after 1, 5 and 10 years. Male sex and distal localization were significantly correlated with lower primary clinical patency. Conclusion: Systemic lysis therapy is an alternative to surgical intervention in acute and subacute aorto-iliac occlusive disease, because it offers acceptable long-term results with a low rate of complications.
