Abstract Background Transvenous Lead Extraction (TLE) is usually performed via a superior approach. Predictors and outcomes of TLE via femoral vein bailout are ill defined. Methods A single tertiary center cohort of 426 consecutive patients who underwent TLE between May 2010 and February 2020 were analyzed. Venography was routinely performed before system upgrade to identify occluded veins. Patients were divided into 2 groups on the basis of the need for femoral bailout extraction. Predictors for TLE requiring femoral bailout and outcomes were analysed. Results A total of 928 leads were extracted and femoral bailout approach was needed in 49 patients (11.5%). A higher proportion of RV leads required femoral bailout approach [51/499 (10.2%)]. Femoral bailout was more common among younger patients, longer lead dwell time, more pocket entries, higher number of extracted leads, presence of abandoned leads [14/49 (28.6%)], and among patients with occluded veins [10/22 (45.5%)]. The presence of abandoned leads, vascular occlusion and age remained a significant predictor for femoral bailout in multivariate analysis. Femoral bailout TLE resulted in a relatively higher rate of major complications [5/49 (10.2%) vs 9/377 (2.4%); p=0.02) but had no related intra-procedural mortality (0/3) and no additional 30 day mortality [2/49 (4.1%) vs 33/377 (8.8%); p=0.4]. Conclusion TLE of abandoned leads, occluded veins and younger age were found to be predictors of femoral bailout requirement. Despite higher rates of major complications in femoral TLE bailout this did not result in increased mortality. Venography before TLE should be considered for procedure planning.

Abstract   The novel myokine myonectin is predominantly expressed in skeletal muscle and is involved in the regulation of metabolic homeostasis. A putative association between myonectin and type 2 diabetes mellitus (T2DM) has been discussed controversially in current literature. The purpose of this study was to investigate the association between myonectin and T2DM at different ages. We measured myonectin in 410 vascular risk patients with a mean age of 66 years. Myonectin did not correlate with age (r=−0.19; p=0.697). From our patients 219 (53%) were >65 years, with a mean age of 74 years and 191 ≤65 years, with a mean age of 57 years. The prevalence of T2DM was 40.6% vs. 42.4% in the older as compared to the younger age group. Myonectin concentrations were significantly decreased in elderly patients with T2DM compared to non-diabetic subjects (1.8 vs. 4.2 ng/ml; p=0.002), whereas no significant difference was observed in younger patients (2.6 vs. 2.3 ng/ml; p=0.183). Concordantly, regression analysis revealed an unadjusted odds ratio (OR) of 0.24 [0.07–0.81] (p=0.021) for the association between myonectin and T2DM in elderly patients but not in younger patients (OR=1.08 [0.80–1.45]; p=0.609). The association between myonectin and T2D; remained significant after adjusting for sex, body mass index, LDL cholesterol, HDL cholesterol, current smoking, as well as statin intake in elderly but remained non-significant in younger patients (OR=0.23 [0.07–0.81]; p=0.021 vs. OR=1.05 [0.76–1.46]; p=0.769). We conclude that plasma myonectin levels are significantly associated with T2DM, particularly in elderly vascular risk patients. FUNDunding Acknowledgement Type of funding sources: None.

Vein Catheterization

Introduction: Central vein catheterization can be introduced in subclavian vein (SCV), internal jugular vein or femoral vein for volume resuscitation and invasive monitoring technique. Due to anatomical advantage and lesser risk of infection subclavian vein is preferred. Either supraclavicular (SC) or infraclavicular (IC) approach could be used for subclavian vein catheterization. The aim of the study was to compare SC and IC approach in ease of catheterization of SCV and record the complications present if any. Methods and materials: This was a hospital based comparative, interventional study conducted from November 2016 to October 2017 in Operation Theater in Bir Hospital. In this study, 70 patients for elective surgical cases meeting the inclusion criteria were randomly enrolled. Then samples were equally divided by lottery into either supraclavicular or infraclavicular approach groups. The Access time, cannulation success rate, attempts made for successful cannulation of vein, easy insertion of catheter and guide wire, approximate inserted length of catheter and associated complications in both groups were recorded. Data was entered in statistical software SPSS 16. Chi-square test was used. P value < 0.05 was considered significant. Results: The mean access time in group SC for SCV catheterization was 2.12 ± 0.81 min compared to 2.83 ± 0.99 min in group IC (p-value= 0.002). The overall success rate in catheterization of the right SCV using SC approach (34 / 35) was better as compared with group IC (33 / 35) using IC approach. First successful attempt in the SC group was 74.28% as compared with 57.14% in the IC group. Conclusion: The SC approach of SCV catheterization can be considered alternative to IC approach in terms of landmark accessibility, success rate and rate of complications.

Abstract Background Managing elderly patients with infection or malfunction deriving from a cardiac implantable electronic device (CIED) may be challenging. The aim of this study was to evaluate safety and efficacy of mechanical transvenous lead extraction (TLE) in elderly patients. Methods Patients who had undergone TLE in single tertiary referral center were divided in two groups (Group 1: ≥80 years; group 2:&lt;80 years) and their acute and chronic outcomes were compared. All patients were treated with manual traction or mechanical dilatation. Results Our analysis included 1316 patients (group 1: 202, group 2: 1114 patients), with a total of 2513 leads extracted. Group 1 presented more comorbidities and more pacemakers, whereas the dwelling time of the oldest lead was similar, irrespectively of patient's age. In group 1 the radiological success rate for lead was higher (99.0% vs 95.9%; P&lt;0.001) and the fluoroscopy time lower (13.0 vs 15.0 minutes; P=0.04) than in group 2. Clinical success was reached in 1273 patients (96.7%), without significant differences between groups (group 1: 98.0% vs group 2: 96.4%; P=0.36). Major complications occurred in 10 patients (0.7%) without significative differences between patients with more or less than 80 years (group 1: 1.5% vs group 2: 0.6%; P=0.24). In the elderly group no in-hospital mortality occurred (0.0% vs 0.5%; P=0.42). Conclusions Mechanical TLE in elderly patients is a safe and effective procedure. In the over-80s, a comparable incidence of major complications with younger patients was observed, with at least a similar efficacy of the procedure and no procedural-related deaths.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiorenal syndrome (CRS) is common in patients with acute heart failure (AHF) and is associated with poor prognosis. Levosimendan (LVS) is an inodilator used in AHF and has beneficial effects on renal function (RF). However, its effects on RF in CRS patients are not established. Purpose To evaluate whether LVS could improve RF in AHF patients with or without CRS. Methods Retrospective study that included patients with AHF treated with LVS in a cardiac intensive care unit of a tertiary center, between January 2015 and June 2018. Baseline serum creatinine (SCr) was recorded and SCr and glomerular filtration rate (GFR) were accessed before and within 5 days after LSV use. CRS was defined as an increase in SCr &gt; 0,3 mg/dL over baseline (before LVS use). RF improvement was defined as a decrease in SCr after LVS use. We evaluate outcomes at 1-year. Results 61 patients were included, 84% males, mean age 65 years, ejection fraction ≤40% in 87%. INTERMACS 4 and hemodynamic profile C were the most frequent presentation. LSV was administered in 24h, without bolus, in most patients. CRS was present in 44,3% of patients. Basal characteristics were similar between CRS and no-CRS patients, including prevalence of chronic kidney disease, baseline SCr or natriuretic peptides (p&gt; 0,05 for all). CRS patients had a significant improvement in RF after LVS use (SCr 2,08 to 1,65 mg/dL, p&lt; 0,001 and GFR 40,4 to 54,6 mL/min/m2, p&lt; 0,001), while no-CRS patients had no significant improvement in RF (SCr 1,33 to 1,32 mg/dL and GFR 64,1 to 64,5 mL/min/m2, p&gt; 0,05 for all). Also, there was a significant decrease in natriuretic peptides after LVS in CRS patients (NT-proBNP 13527,5 to 10708,8 pg/mL, p= 0,006), without significant differences in no-CRS patients. It is noteworthy that at discharge, CRS patients were more likely to titrate HF optimal medical therapy (OMT) compared with no-CRS patients (p= 0,039). There was a lower tendency to suspend angiotensin-converting enzyme (ACE-I) and angiotensin receptor blockers (ARB) in CRS patients (p= 0,05). At discharge CRS patients received more furosemide than at admission (77,2 mg/day to 97,1 mg/day, p= 0,019) compared with no-CRS patients (89,6 mg/day to 97,0 mg/day, p= 0,469), receiving similar doses at discharge. In CRS patients, RF improvement was associated with a decrease in intra-hospital mortality (p= 0,043) and a tendency to decrease 30-day mortality (p= 0,060), but without differences in one-year mortality. Conclusion In CRS patients, LVS improved RF and NT-proBNP, allowed to titrate OMT and decreased the need to suspend ACE-I or ARB and was associated to a decrease in short-term mortality.

Major Adverse Events

Introduction: Percutaneous transvenous lead extraction of cardiovascular implantable electronic devices (CIEDs) is increasingly common. Although ICD leads are widely considered to be more difficult to extract than pacemaker leads, there are few direct comparisons. Methods/Results: Using a cohort of 368 consecutive patients undergoing lead extraction (dwell time >1 year) between 2005-2012, we compared baseline characteristics/outcomes in extractions involving pacing versus ICD leads. We defined major adverse events (MAE) as any events/complications that required procedural intervention, transfusion, or that resulted in death or serious harm during index hospitalization. Median age was 60.6 yrs and 29.6% were women. There were 136 (37%) pacing lead extractions and 232 (63%) ICD lead extractions. Pacing leads had a longer dwell time (6.14 yrs [IQR 1.2-10.9 ] versus 4.4 yrs [IQR 1.1-6.4], p<0.001) and higher median LVEF (55% [IQR 35-55] vs. 30% [IQR 20-40], p<0.001) compared with ICD lead patients. Indications for pacing and ICD lead extractions included sepsis/endocarditis (21.3% vs. 24.6%, p=0.48), pocket infection (40.4% vs. 34.9%, p=0.29), and lead failure (15.4% vs. 38.8%, p<0.001). There were no significant differences between pacing and ICD lead extractions in median fluoroscopy time (5.5 vs. 8.5 minutes, p=0.86) or femoral bailout rate (4.4% vs. 5.2%, p=0.73). There were similar rates of all-cause MAE during index hospitalization (5.1% vs. 5.6%), death (2.2% vs 3.2%) and clinical success (97.0% vs. 97.0%, p=0.55) in pacemaker and ICD extractions, respectively. Conclusions: ICD leads are more commonly extracted relative to pacemaker leads, and this difference is driven by larger numbers of lead failure within ICD leads. Despite much longer dwell times, major adverse events were similar in pacing lead cases compared with ICD extractions.

Introduction: Pacemaker and ICD lead failure or vascular occlusion can require lead extraction. Predictors of a need for lead extraction due to venous occlusion are not well characterized. Hypothesis: Coronary artery disease (CAD) is an independent predictor of lead extraction due to venous occlusion. Methods: We performed a retrospective study of consecutive patients in a prospectively collected registry at a single center undergoing lead extraction due to either venous occlusion or lead failure from 10/2011 to 02/2020. Patients requiring lead extraction due to infection were excluded. Continuous variables are reported as mean ± standard deviation or total number reported as a percentage (%). Chi square test and logistic regression were used to estimate difference in rates and Odds Ratio. Statistically significant findings were identified with a p valve < 0.05. Results: Of 384 procedures included in the database, 131 patients met inclusion criteria for venous occlusion (17%) or lead failure (83%) (Table 1). Average age of the cohort was 55.1 ± 16.4 years and 51% were female. Baseline ejection fraction was 44.6 ± 15.5% and 19.7% of patients had NYHA class III or IV symptoms. 29.7% had a history of CAD. Average number of leads extracted was 1.3 ± 0.57 compared to 2.1 ± 0.82 leads in situ. Patients with CAD had a statistically significant increased risk for extraction as a result of venous occlusion Odds Ratio of 6.80, 95% CI 2.47-18.6, p = 0.0001. Conclusions: Identification of predictors of venous occlusion and risk stratification of these patients is an important component of procedural planning and shared decision making. CAD is a predictor of venous occlusion in patients undergoing lead extraction and should be assessed as a risk factor for complex lead management decisions. Further study is warranted to identify mechanisms by which this relationship can be used to predict need for extraction due to vascular occlusion.

The Impact

IntroductionThe 4 h emergency standard for English acute trusts was introduced in 2003 and became full established by 2008 at 98% for all Emergency Department (ED) patients to be seen and discharged. This study examined the impact of the target for older patients attending departments.MethodsRoutine patient level data was received from 15 English EDs representing 774 095 individual patient attendances during May and June for 2003 to 2006. The data were used to determine the distribution of the total time spent in the EDs. Attendances were compared for older patients (65 years and above) with younger age groups.ResultsA total of 145 596 attendances were for patients aged 65+ years (18.9%). Across each year analysed, these older patients have a significantly longer median total time in the ED than those younger than 65 years (162 min vs 103 min, p<0.001). In addition, older patients are significantly more likely to leave the emergency department in the last 20 min prior to 4 h (12.4% vs 5.2% in those <65 years, p<0.001). This proportion is growing year on year in both the admitted and discharged categories of patients. Finally, older patients are significantly more likely to breach the 4-h than their younger counterparts (16.6% vs 6.3%, p<0.001).ConclusionsThere are some unintended consequences of introducing the 4 h target in UK emergency departments. While the target has reduced overall time in departments, the older patient appears to be disadvantaged relative to younger patients. Older patients are more likely to be ‘rushed through’ to other unmonitored areas of the hospital just prior to the target or to breach the target altogether. This finding calls in to question the benefits that the target is conveying for individual patients, and especially the most vulnerable in society.

Abstract Funding Acknowledgements Type of funding sources: None. Background Extraction of cardiac implantable electronic device (CIED) leads using excimer laser is in use since &gt; 20 years, but the predictors of success, all-cause complications and mortality are not yet sufficiently statistically evaluated.  Method All consecutive laser extractions performed at our institution between September 2011 and March 2020 with lead age &gt; 12 months were included and retrospectively analysed. Results 792 leads (mean age 75 months) were extracted during 335 procedures. The indication for extraction was pocket infection in 59%, CIED endocarditis in 25%, lead dysfunction or upgrade in 14% and others in 2%. 94.6% of leads were extracted complete, 4.2% partial (&lt; 4 cm rest) and the extraction failed in 1.3% of the leads (retention of ≥ 4 cm rest). Multivariable analysis identified lead age &gt; 7.5 years (odds ratio [OR] 6.5; p = 0.0281), broken leads (OR 28.0; p = 0.0009) and implantable cardioverter-defibrillator (ICD) leads (OR 6.5; p = 0.0010) as independent predictors of failed extraction. CIED-endocarditis was independently associated with complete extraction (OR 3.3; p = 0.0218). Complete procedural success or clinical success was achieved in 330 of 335 procedures (98.6%). The lead extraction failed in five cases (1.5%). Major procedure-associated adverse events (injuries of the great vessels or heart) occurred in four cases (1.2%). Two patients died perioperatively (0.6%). Minor complications occurred in 13 cases (3.9%). Major adverse events (MAE) causally not related to the procedure occurred in 18 (5.4%) of the patients. The most frequent MAE was postoperative aggravation of the sepsis (10 patients; 3.0%).  Independent predictors of major adverse events were CIED-endocarditis (OR 6.0; p = 0.0175), preoperative C-reactive-protein (CRP) &gt; 35 mg/l (OR 3.8; p = 0.0412) and body mass index (BMI) ≥ 25 kg/m2 (OR 5.0; p = 0.0489). Ten patients (3%) died during the hospital stay.  CIED-endocarditis with preoperative CRP &gt; 35 mg/l was independently associated with hospital mortality in multivariable analysis (OR 10.7; p = 0.0020). The Kaplan-Meyer analysis of 30-day mortality showed a significantly worse survival of patients with endocarditis (Log-Rank p = 0.0102). Conclusion Leads &gt; 7.5 years, broken leads and ICD leads are independent predictors of failed extraction. CIED endocarditis, CRP &gt; 35 and BMI ≥ 25 are associated with MAE. CIED endocarditis is related to higher short-term mortality despite successful lead extraction. Abstract Figure.

Previously we reported that pulmonary vascular pressure gradients determined by vascular occlusion varied as a function of neonatal age. The purpose of this study was to evaluate the effect of blood flow on pressure gradients during normoxia (inspired O2 28%) and hypoxia (inspired O2 4.2%) in isolated, indomethacin-treated lungs obtained from lambs at less than 1, 2-4, 12-14, and 30-32 days of age (n = 6 at each age). The total pulmonary pressure gradient was partitioned into pressure gradients across relatively indistensible arteries and veins and relatively compliant vessels in the middle region (delta Pm) by inflow and outflow occlusions at flows of 25, 50, 75, and 100 ml.kg-1.min-1. During normoxia, lungs from lambs less than 1 day of age had significantly greater pressures at each flow than lungs from older lambs, due primarily to a significantly greater delta Pm in this age group. During hypoxia, the greatest vasoconstriction occurred in the youngest group, also due mostly to an increased delta Pm. This enhanced response to hypoxia in the younger age groups was due to inhibition of prostaglandin synthesis; without indomethacin treatment, the older age groups had a greater hypoxic pressor response than the younger groups. The arterial vascular resistance at all ages was relatively constant as a function of blood flow during both normoxia and hypoxia, whereas the total and middle vascular resistances generally decreased as a function of flow. The venous resistance initially decreased and then was constant. These results suggest that the neonatal pulmonary circulation h as a fixed arterial resistance, a slightly distensible venous region at low flows, and a more distensible middle region.

Colonic diverticular disease is responsible for over 300,000 admissions and expenditures exceeding $2.7 billion/year. There is recent evidence that rates of treatment for diverticulitis have increased in the United States over the last decade. We hypothesize that these national trends of increasing rates of hospitalizations for diverticulitis would be found in an analysis of a single-state discharge database. Data from the Office of Statewide Health Planning and Development were used to analyze treatment for diverticulitis in California from 1995 to 2006. For each hospitalization, surgical care was determined based on procedure codes for left colon resection and/or colostomy. Overall numbers of admissions for acute diverticulitis increased throughout the 12-year study period with an estimated annual percentage of change (EAPC) of 2.1 per cent (P < 0.001). Rates of admissions increased most rapidly in patients 20 to 34-years-old (EAPC = 8.6%, P < 0.001) and 35 to 49 years old (EAPC = 5.7%, P < 0.001). Elective colectomies had an EAPC of 2.1 per cent (P < 0.001), which was also most dramatic in younger age groups. Between 1995 and 2006 we found significant increases in both the rates of hospitalization for diverticulitis and rates of elective surgical treatment in California. These increases are entirely due to higher rates of care for younger patients.
