426 Percutaneous or surgical access for transfemoral transcatheter aortic valve implantation: a propensity matched analysis of a multicentre registry

Abstract Aims The transfemoral (TF) approach appeared to be the safest and the broadest used approach in TAVI, characterized by a lower rate of periprocedural bleedings and vascular complications and is currently recommended by the guidelines as a first line approach when feasible. If in the early experience TF access was achieved using a surgical cutdown approach, through the last years, there has been increasing evidence of the safety and efficacy of a fully percutaneous approach over a surgical access, albeit available evidences are controverting and mostly including first generation prostheses and high risk patients. The aim of the study is to compare percutaneous and surgical access in a large, real-word, multicentre of TF TAVI. Methods and results Consecutive patients undergoing successful TF TAVI were prospectively enrolled in local clinical registries of five high volume centres in Italy: IRCCS Ospedale Policlinico San Martino (Genoa), IRCCS Policlinico San Donato (Milan), Città Della Salute e della Scienza, (Turin), Ospedale Niguarda Ca’ Granda (Milan), Magna Graecia University, (Catanzaro), between January 2014 to December 2019. Univariate and multivariate analysis using IPTW were performed. A total of 1946 TF TAVI patients (female 42.8%) were prospectively included. Patients underwent surgical access had a significantly higher surgical risk (STS score of 8.9 vs. 6.4, P < 0.001, and EuroSCORE of 15.1 vs. 8.7, P < 0.001, respectively). Overall survival was comparable between the two groups (HR: 1.14, 95% CI: 0.76–1.71). Patients who underwent surgical access experienced more VARC-2 major and VARC-2 minor vascular complications (13% vs. 7%, P = 0.003 and 11% vs. 6.1%, P = 0.007, respectively) and more VARC-2 major/life threatening and minor bleeding (27.4% vs. 17.8, P = 0.001, and 9.6% vs. 2.1%, P < 0.001, respectively). After IPTW adjustment, surgical access was associated with an increased risk of major vascular complications (HR: 3.32, 95% CI: 1.84–5.97), minor bleeding (HR: 4.24, 95% CI: 1.16–15.54) and stage 2–3 AKI (HR: 2.60, 95% CI: 1.07–6.33). Conclusions The performance of the percutaneous transfemoral TAVI approach was safe and feasible and resulted in fewer major vascular complications, bleedings and AKI than the surgical femoral isolation. Procedural time and hospital length were also lower in the percutaneous group. Routine application of the percutaneous approach might reduce acute complications in patients undergoing transfemoral TAVI and reduce procedural time and hospital length.

The prevalence of heart failure is markedly increased in individuals with diabetes mellitus. Numerous observational studies suggest that this increased risk for heart failure can be attributed to exacerbated vascular complications and the presence of increased risk factors in diabetic subjects. In addition, experimental studies revealed the presence of a number of distinct molecular alterations in the myocardium that occur independently of vascular disease and hypertension. Many of these molecular alterations are similarly observed in failing hearts of nondiabetic patients and have thus been proposed to contribute to the increased risk for heart failure in diabetes. The interest in understanding the underlying mechanisms of impaired cardio- vascular outcomes in diabetic individuals has much increased since the demonstration of cardioprotective effects of SGLT-2 inhibitors and GLP-1 receptor agonists in recent clinical trials. The current review therefore summarizes the distinct mechanisms that have been proposed to increase the risk for heart failure in diabetes mellitus.

Diabetes mellitus (DM) is a complex metabolic disease affecting one-third of the United States population. It is characterized by hyperglycemia, where the hormone insulin is either not produced sufficiently or where there is a resistance to insulin. Patients with Type 1 DM (T1DM), in which the insulin-producing beta cells are destroyed by autoimmune mechanisms, have a significantly increased risk of developing life-threatening cardiovascular complications, even when exogenous insulin is administered. In fact, due to various factors such as limited blood glucose measurements and timing of insulin administration, only 37% of T1DM adults achieve normoglycemia. Furthermore, T1DM patients do not produce C-peptide, a cleavage product from insulin processing. C-peptide has potential therapeutic effects in vitro and in vivo on many complications of T1DM, such as peripheral neuropathy, atherosclerosis, and inflammation. Thus, delivery of C-peptide in conjunction with insulin through a pump, pancreatic islet transplantation, or genetically engineered Sertoli cells (an immune privileged cell type) may ameliorate many of the cardiovascular and vascular complications afflicting T1DM patients.

BackgroundGiven the increasing numbers of older patients presenting with trauma, and the potential influence of delirium on outcomes, we sought to investigate the proportion of such patients who were diagnosed with delirium during their stay—and patient factors associated therewith—and the potential associations between delirium and hospital length of stay (LOS). We hypothesized that delirium would be common, associated with certain patient characteristics, and associated with long hospital LOS (highest quartile).MethodsWe conducted a retrospective observational cohort study of all trauma patients aged ≥65 years presenting in September to October 2019, interrogating medical records and the institutional trauma database. The primary outcome measure was occurrence of delirium.ResultsAmong 99 eligible patients, delirium was common, documented in 23% (23 of 99). On multivariable analysis, adjusting for age, frailty and history of dementia, frailty (OR 4.09, 95% CI 1.08 to 15.53, p=0.04) and dementia (OR 5.23, 95% CI 1.38 to 19.90, p=0.02) were independently associated with likelihood of delirium. Standardized assessment tools were underused, with only 34% (34 of 99) screened within 4 hours of arrival. On univariate logistic regression analysis, having an episode of delirium was associated with long LOS (highest quartile), OR of 5.29 (95% CI 1.92 to 14.56, p<0.001). In the final multivariable model, adjusting for any (non-delirium) in-hospital complication, delirium was independently associated with long LOS (≥16 days; OR 4.81, p=0.005).DiscussionIn this study, delirium was common. History of dementia and baseline frailty were associated with increased risk. Delirium was independently associated with long LOS. However, many patients did not undergo standardized screening at admission. Early identification and targeted management of older patients at risk of delirium may reduce incidence and improve care of this vulnerable cohort. These data are hypothesis generating, but support the need for initiatives which improve delirium care, acknowledging the complex interplay between frailty and other geriatric syndromes in the older trauma patients.Level of evidenceIII.

Abstract Objective: Children with CHD may be at increased risk for epilepsy. While the incidence of perioperative seizures after surgical repair of CHD has been well-described, the incidence of epilepsy is less well-defined. We aim to determine the incidence and predictors of epilepsy in patients with CHD. Methods: Retrospective cohort study of patients with CHD who underwent cardiopulmonary bypass at <2 years of age between January, 2012 and December, 2013 and had at least 2 years of follow-up. Clinical variables were extracted from a cardiac surgery database and hospital records. Seizures were defined as acute if they occurred within 7 days after an inciting event. Epilepsy was defined based on the International League Against Epilepsy criteria. Results: Two-hundred and twenty-one patients were identified, 157 of whom were included in our analysis. Five patients (3.2%) developed epilepsy. Acute seizures occurred in 12 (7.7%) patients, only one of whom developed epilepsy. Predictors of epilepsy included an earlier gestational age, a lower birth weight, a greater number of cardiac surgeries, a need for extracorporeal membrane oxygenation or a left ventricular assist device, arterial ischaemic stroke, and a longer hospital length of stay. Conclusions: Epilepsy in children with CHD is rare. The mechanism of epileptogenesis in these patients may be the result of a complex interaction of patient-specific factors, some of which may be present even before surgery. Larger long-term follow-up studies are needed to identify risk factors associated with epilepsy in these patients.

Procedural Complications

Introduction: Women undergoing atrial fibrillation catheter ablation (AFCA) have higher rates of vascular complications and major bleeding. However, studies have been underpowered to detect differences in rare complications such as stroke/transient ischemic attack (TIA) and procedural mortality. Methods: We performed a systematic review of databases (PubMed, World of Science, Embase) to identify studies published since 2010 reporting AFCA complications by gender. Six complications of interest were: 1) vascular/groin complications; 2) pericardial effusion/tamponade; 3) stroke/TIA; 4) permanent phrenic nerve injury; 5) major bleeding & 6) procedural mortality. For meta-analysis, random effects models were used when heterogeneity between studies was ≥ 50% (vascular complications, major bleeding) and fixed effects models for other endpoints. Results: Of 5716 citations, 19 studies met inclusion criteria, comprising 244,353 patients undergoing AFCA, of whom 33% were women. Women were older (65.3 ± 11.2 vs. 60.4 ± 13.2 years), more likely hypertensive (60.6 vs. 55.5%) and diabetic (18.3 vs. 16.5%) and had higher CHA 2 DS 2 -VASc scores (3.0 ± 1.8 vs. 1.4 ± 1.4) (p<0.0001 for all comparisons). The rates of all 6 complications were significantly higher in women (Table). However, despite statistically significant differences, the overall incidences of major complications were very low in both genders: stroke/TIA (women 0.51 vs. men 0.39%) and procedural mortality (women 0.25 vs. men 0.18%). Conclusion: Women experience significantly higher rates of AFCA complications. However, the incidence of major procedural complications is very low in both genders. The higher rate of complications in women may be partially attributable to older age and a higher prevalence of comorbidities at the time of ablation. More detailed studies are needed to better define the mechanisms of increased risk in women and to identify strategies for closing the gender gap.

Abstract Endothelium, the inner layer of the vasculature, represents the interface between blood and organ systems and it is active in the process of contraction and relaxation of vascular smooth muscle and in functions like secretion of vasoactive substances. Endothelial dysfunction is an important cause of cardiovascular disease. The function of the endothelium can be assessed by invasive and noninvasive methods. Endothelial cells produce vasoactive substances like endothelium derived relaxing factor, prostacyclin, nitric oxide, and endothelium derived hyperpolarizing factor. Diabetes mellitus is associated with an increased risk of cardiovascular diseases. Hyperglycemia leads to cardiovascular damage through different pathways, including the polyol and hexosamine pathways, generation of advanced glycation end products, and activation of protein kinase C. Together with hyperglycemia induced mitochondrial dysfunction and endoplasmic reticulum stress, all these can promote the accumulation of reactive oxygen species. The oxidative stress induced by hyperglycemia promotes endothelial dysfunction with an important role in micro and macro vascular disease. Insulin-resistance could be independently predictive of cardiovascular disease. Life style modification and pharmacotherapy could possibly ameliorate the effect of insulin resistance

Purpose The purpose of this study was to evaluate the safety of antithrombotic treatments prescribed during pregnancy in patients with antiphospholipid syndrome (APS). Methods This international, multicenter study included two cohorts of patients: a retrospective French cohort and a prospective US cohort (PROMISSE study). Inclusion criteria were (1) APS (Sydney criteria), (2) live pregnancy at 12 weeks of gestation (WG) with (3) follow-up data until six weeks post-partum. According to APS standard of care, patients were treated with aspirin and/or low-molecular weight heparin (LMWH) at prophylactic (pure obstetric APS) or therapeutic doses (history of thrombosis). Major bleeding was defined as abnormal blood loss during the pregnancy and/or post-partum period requiring intervention for hemostasis or transfusion, or during the peripartum period greater than 500 mL and/or requiring surgery or transfusion. Other bleeding events were classified as minor. Results Two hundred and sixty-four pregnancies (87 prospectively collected) in 204 patients were included (46% with history of thrombosis, 23% with associated systemic lupus). During pregnancy, treatment included LMWH ( n = 253; 96%) or low-dose aspirin ( n = 223; 84%), and 215 (81%) patients received both therapies. The live birth rate was 89% and 82% in the retrospective and prospective cohorts, respectively. Adverse pregnancy outcomes occurred in 28% of the retrospective cohort and in 40% of the prospective cohort. No maternal death was observed in either cohort. A combined total of 45 hemorrhagic events (25%) occurred in the retrospective cohort, but major bleeding was reported in only six pregnancies (3%). Neither heparin nor aspirin alone nor combined therapy increased the risk of hemorrhage. We also did not observe an increased rate of bleeding in the case of a short interval between last LMWH (less than 24 hours) or aspirin (less than five days) doses and delivery. Only emergency Caesarean section was significantly associated with an increased risk of bleeding (odds ratio (OR) 5.03 (1.41–17.96); p=.016). In the prospective cohort, only one minor bleeding event was reported (vaginal bleeding). Conclusion Our findings support the safety of antithrombotic therapy with aspirin and/or LMWH during pregnancy in high-risk women with APS, and highlight the need for better treatments to improve pregnancy outcomes in APS.

Pancreatic fistula continues to be a common complication following PD. This study seeks to identify clinical factors which may predict pancreatic fistula (PF) and evaluate the effect of PF on outcomes following pancreaticoduodenectomy (PD). We performed a retrospective analysis of a clinical database at an academic tertiary care hospital with a high volume of pancreatic surgery. Five hundred ten consecutive patients underwent PD, and PF occurred in 46 patients (9%). Perioperative mortality of patients with PF was 0%. Forty-five of 46 PF (98%) closed without reoperation with a mean time to closure of 34 days. Patients who developed PF showed a higher incidence of wound infection, intra-abdominal abscess, need for reoperation, and hospital length of stay. Multivariate analysis demonstrated an invaginated pancreatic anastomosis and closed suction intraperitoneal drainage were associated with PF whereas a diagnosis of chronic pancreatitis and endoscopic stenting conferred protection. Development of PF following PD in this series was predicted by gender, preoperative stenting, pancreatic anastomotic technique, and pancreas pathology. Outcomes in patients with PF are remarkable for a higher rate of septic complications, longer hospital stays, but in this study, no increased mortality.

Vt Ablation

Introduction: Use of inotropes such as dobutamine remains controversial in the management of heart failure (HF) due to uncertain efficacy and lack of mortality benefit. Furthermore, vasoactive drugs are frequently utilized during VT ablations despite minimal data regarding their effects on outcomes. Vasoactive drugs may impact factors such as long-term VT recurrences and hospital length of stay. Hypothesis: We sought to evaluate the hypothesis that the use of dopamine, dobutamine or phenylephrine have differential effects on outcomes after VT ablations. Methods: A retrospective analysis was completed for all VT ablations from 2013-17 at our institution. Patient characteristics and procedural details were collected for 149 VT ablation cases. Results: The cohort was 81% male, and 67% had cardiomyopathy of which 53% were ischemic with a mean EF of 29% (CI 26.7- 31.4). Average procedure time was 368 minutes (CI 347-388). Vasoactive drugs were used in 87% of patients undergoing VT ablation: phenylephrine (67%), dopamine (40%), dobutamine (37%). The median LOS for all patients was 5 days (mean 7 days, range 1 - 56 days, IQR 2 - 9 days). After adjusting for inducibility, HF and procedural time, the dose of dobutamine, but not dopamine or phenylephrine, was significantly associated with increased length of stay (Fig. 1a). Inducible VT at the end of the procedure also correlated with increased LOS (5.4±0.3 vs 8.6±0.3, p < 0.0001). Procedural time did not associate with increased LOS. Of all covariates, only the number of VTs induced during the procedure was significantly associated with increased VT recurrence (HR 1.22/VT morphology (CI 1.11-1.34, p < 0.001)). Conclusions: Dobutamine, but not phenylephrine or dopamine, was significantly associated with increased length of stay after adjusting for HF, procedural time and inducibility of VT. More research is needed regarding vasoactive drug use in VT ablations and their significance to procedural and post-procedure outcomes.
