Background This meta-analysis aimed to compare the potential effects of local anesthesia (LA) and general anesthesia (GA) for transcather aortic value implantation (TAVI). Measurements All relevant studies were searched from the Pubmed, EMbase, Web of Science and the Cochrane Library (January 1, 2016 to June 1, 2021). The main outcomes of this literature meta-analysis were 30-day mortality, procedural time, new pacemaker implantation, total stay in hospital, the use of vasoactive drug, intra-and postoperative complications and emergencies, including conversion to open, myocardial infraction, pulmonary complication, vascular complication, renal injury/failure, stroke, transesophageal echocardiography, life-threatening/major bleeding, cardiac tamponade, emergency PCI. Pooled risk ratio (RR) and mean difference (MD) together with 95% confidence interval (CI) were calculated. Results A total of seventeen studies including 20938 patients in the final analysis fulfilled the inclusion criteria. Intra-and postoperative complications (myocardial infraction, vascular complication, renal injury/failure, stoke, cardiac tamponade) undergoing TAVI in serious AS patients under GA do not offer significant difference compared with LA. No differences are observed between LA and GA for new pacemaker implantation, total stay in hospital, transesophageal echocardiography, emergency PCI. GA is associated with more adverse events, like the more overall mortality (RR 0.69, p=0.600), pulmonary complications (RR 0.54, p=0.278), life-threatening/major bleeding (RR 0.85, p=0.855), the more times of coversion to open (RR 0.22, p=0.746). LA has many advantages, including a shorter procedure duration (MD=-0.38, p=0.000) and a reduction of the use of vasoactive drug (RR 0.57，P=0.000). Conclusions For TAVI, both LA with or without sedation and GA are feasible and safe. LA appears a feasible alternative to GA for AS patients undergo TAVI.

Adequate anticoagulation during catheter ablation (CA) for atrial fibrillation (AF) is crucial for the prevention of both thromboembolic events and life-threatening bleeding. The purpose of this updated meta-analysis is to compare the safety and efficacy of uninterrupted and minimally interrupted periprocedural direct oral anticoagulant (DOAC) protocols and uninterrupted vitamin K antagonist (VKA) therapy in patients undergoing CA for AF based on the latest evidence. Randomized controlled trials, prospective observational studies, and retrospective registries comparing DOACs to VKAs were identified in multiple databases (Embase, MEDLINE via PubMed, CENTRAL, and Scopus). The primary outcomes were stroke or transient ischemic attack (TIA), major bleeding, and net clinical benefit. Forty-two studies with a total of 22,715 patients were included in the final analysis. The occurrence of major bleeding was significantly lower in patients assigned to uninterrupted DOAC treatment compared to VKAs (pooled odds ratio (POR): 0.71, confidence interval (CI): 0.51–0.99). The pooled analysis of both uninterrupted and minimally interrupted DOAC groups also showed significant reduction in major bleeding events (POR: 0.70, CI: 0.53–0.93). The incidence of thromboembolic events was low, with no significant difference between groups. This updated meta-analysis showed that DOAC therapy is as effective as VKA in preventing stroke and TIA. Minimally interrupted DOAC therapy is a non-inferior periprocedural anticoagulation strategy; however, uninterrupted DOAC therapy showed superiority compared to VKA with regard to major, life-threatening bleeding. Based on our in-depth analysis, we conclude that both DOAC strategies are equally safe and preferable alternatives to VKAs in patients undergoing CA for AF.

Abstract Aims To investigate the clinical outcomes associated with an antithrombotic therapy with or without clopidogrel after transcatheter aortic valve replacement (TAVR). Methods and results This is a study-level meta-analysis including all randomized trials investigating antithrombotic regimens after TAVR. The protocol was registered with PROSPERO (CRD42020191036). We searched electronic scientific databases for eligible studies. The primary outcome was all-cause death. Main secondary outcome was major bleeding. Other outcomes were life-threatening (or disabling) bleeding, myocardial infarction (MI) and stroke. Six eligible trials randomly allocated 3056 TAVR patients to aspirin or oral anticoagulation (OAC) with clopidogrel (n = 1525) versus aspirin and/or OAC without clopidogrel (n = 1531). In the overall estimates, an antithrombotic therapy with clopidogrel versus without displayed a comparable risk of all-cause death [Risk Ratio—RR = 0.83, 95% Confidence intervals—CI (0.57–1.20); P = 0.25] and major bleeding [RR = 1.33, 95% CI (0.61–2.92); P = 0.39]. However, the combination of aspirin or OAC with clopidogrel doubled the risk of major bleeding as compared to aspirin or OAC without clopidogrel [RR = 2.08, 95% CI (1.27–3.42); P = 0.015, P for interaction = 0.021]. Treatment strategies did not differ with respect to the risk of life-threatening bleeding, MI and stroke. Conclusions In patients receiving TAVR, a therapeutic strategy of aspirin or OAC with clopidogrel significantly increases the risk of major bleeding without impact on mortality and ischemic outcomes compared to aspirin or OAC without clopidogrel. The performance of different antithrombotic regimens in terms of long-term clinical outcomes and bioprosthesis valve function requires further investigation.

Abstract Background Adequate anticoagulation in catheter ablation of atrial fibrillation (AF) is crucial in preventing both thromboembolic events and life-threatening bleeding. As clinicians gain more experience and reassurance with data from clinical trials, the usage of Direct Oral Anticoagulants (DOAC) in patients undergoing catheter ablation of AF has rapidly increased over the last years. The purpose of this updated meta-analysis was to assess the latest evidence and compare the safety and efficacy of uninterrupted and minimally interrupted periprocedural DOAC anticoagulation protocols with uninterrupted Vitamin K Antagonists (VKA) in this setting. Methods Randomized or prospective controlled observational studies comparing DOACs to VKAs were identified with multiple databases (Embase, PubMed, Cochrane, and Scopus). Uninterrupted and minimally interrupted DOAC (single dose of dabigatran or apixaban withheld) were distinguished, VKA therapy was always uninterrupted. The primary outcomes were stroke or transient ischemic attack (TIA), major bleeding, and net clinical benefit. Results 32 studies were included in the final analysis, encompassing a total of 19.437 patients. The incidence of thromboembolic events was rare (less than 0.2%), with no significant difference between groups. Occurrence of major bleeding and net clinical benefit were significantly improved in patients assigned to uninterrupted DOAC treatment compared to VKAs (1.5% vs 2.2%, POR: 0.74, CI: 0.56–0.98, I2=0,0% and 1.7% vs 2.4%, POR: 0.76; CI: 0.59–0.99, I2=0,0%, respectively). Net clinical benefit Conclusion This updated meta-analysis, based on a large database, showed that DOAC therapy is equally effective as VKA in preventing stroke and TIA. Minimally-interrupted DOAC therapy is a non-inferior peri-procedural anticoagulation strategy, however, uninterrupted DOAC therapy showed superiority when compared to VKA regarding major, life-threatening bleeding. Our findings showed that uninterrupted periprocedural DOAC therapy is a safe and preferable alternative to VKAs in patients undergoing catheter ablation for atrial fibrillation.

Background: Although mainstream guidelines recommend dual antiplatelet therapy (DAPT) with aspirin and clopidogrel in patients following transcatheter aortic valve replacement (TAVR), it is not evidence-based. We aim to investigate the safety and efficacy of DAPT vs. single antiplatelet therapy (SAPT) after TAVR, and review updated evidence.Methods: We systematically searched PubMed, Embase, and Cochrane for studies comparing DAPT to SAPT after TAVR from inception to November 30, 2020. The primary outcome was major adverse cardiac and cerebrovascular events, including all-cause mortality, cardiovascular death, myocardial infarction (MI), stroke, and major or life-threatening bleeding (LTB). Subgroup analysis was performed according to study type (randomized control trials vs. observational studies) using a fixed-effects model. The quality of evidence was assessed by two scoring systems and GRADE (Grading of Recommendations Assessment, Development, and Evaluation).Results: Twelve studies of 20,766 patients were included in our meta-analysis. Compared with SAPT, DAPT was associated with an increased risk for combined life threatening and major bleeding [OR 1.73 (1.19–2.51), p = 0.004] after TAVR. Such a difference was largely driven by major bleeding [OR 2.29 (1.68–3.11), p < 0.001]. There were no significant differences on major adverse cardiovascular events (MACE) [OR 1.19 (0.99–1.44), p = 0.07], cardiovascular mortality [OR 1.46 (0.93–2.30), p = 0.10], and stroke [OR 0.97 (0.80–1.16), p = 0.71].Conclusions: Compared with SAPT, post-TAVR DAPT was associated with increased risks of major or life-threatening bleeding without additional benefits of reducing thrombotic events. Future guidelines for post-TAVR antiplatelet strategy are expected to be updated as new high-quality evidence emerges.Systematic Review Registration: PROSPERO, Identifier: CRD42021230075.

OBJECTIVE Awake surgery has previously been found to improve patient outcomes postoperatively in a variety of procedures. Recently, multiple groups have investigated the utility of this modality for use in spine surgery. However, few current meta-analyses exist comparing patient outcomes in awake spinal anesthesia with those in general anesthesia. Therefore, the authors sought to present an updated systematic review and meta-analysis investigating the utility of spinal anesthesia relative to general anesthesia in lumbar procedures. METHODS Following a comprehensive literature search of the PubMed and Cochrane databases, 14 clinical studies were included in our final qualitative and quantitative analyses. Of these studies, 5 investigated spinal anesthesia in lumbar discectomy, 4 discussed lumbar laminectomy, and 2 examined interbody fusion procedures. One study investigated combined lumbar decompression and fusion or decompression alone. Two studies investigated patients who underwent discectomy and laminectomy, and 1 study investigated a series of patients who underwent transforaminal lumbar interbody fusion, posterolateral fusion, or decompression. Odds ratios, mean differences (MDs), and 95% confidence intervals were calculated where appropriate. RESULTS A meta-analysis of the total anesthesia time showed that time was significantly less in patients who received spinal anesthesia for both lumbar discectomies (MD −26.53, 95% CI −38.16 to −14.89; p = 0.00001) and lumbar laminectomies (MD −11.21, 95% CI −19.66 to −2.75; p = 0.009). Additionally, the operative time was significantly shorter in patients who underwent spinal anesthesia (MD −14.94, 95% CI −20.43 to −9.45; p < 0.00001). Similarly, when analyzing overall postoperative complication rates, patients who received spinal anesthesia were significantly less likely to experience postoperative complications (OR 0.29, 95% CI 0.16–0.53; p < 0.0001). Furthermore, patients who received spinal anesthesia had significantly lower postoperative pain scores (MD −2.80, 95% CI −4.55 to −1.06; p = 0.002). An identical trend was seen when patients were stratified by lumbar procedures. Patients who received spinal anesthesia were significantly less likely to require postoperative analgesia (OR 0.06, 95% CI 0.02–0.25; p < 0.0001) and had a significantly shorter hospital length of stay (MD −0.16, 95% CI −0.29 to −0.03; p = 0.02) and intraoperative blood loss (MD −52.36, 95% CI −81.55 to −23.17; p = 0.0004). Finally, the analysis showed that spinal anesthesia cost significantly less than general anesthesia (MD −226.14, 95% CI −324.73 to −127.55; p < 0.00001). CONCLUSIONS This review has demonstrated the varying benefits of spinal anesthesia in awake spine surgery relative to general anesthesia in patients who underwent various lumbar procedures. The analysis has shown that spinal anesthesia may offer some benefits when compared with general anesthesia, including reduction in the duration of anesthesia, operative time, total cost, and postoperative complications. Large prospective trials will elucidate the true role of this modality in spine surgery.

В статье представлены данные оригинального исследования по улучшению хирургического лечения аневризм брюшного отдела аорты. С этой целью произведен сравнительный анализ двух альтернативных друг другу операций: 1) резекции аневризмы с последующим протезированием аорты; 2) эндопротезирования аорты. Сформулировано научное предположение о том, что замена «классических» операций резекции аневризмы на «альтернативные» операции эндопротезирования приведет к принципиальному снижению уровня послеоперационных осложнений. В независимых группах пациентов с использованием сравниваемых хирургических вмешательств произведена точная качественная и количественная оценка послеоперационных осложнений: нетромботических - кардиальных, пульмональных, ренальных и тромботических - тромбозов глубоких вен и тромбозов браншей протеза. После реализации исследования было установлено, что замена «классических» операций на «альтернативные» достоверно приводит к принципиальному снижению уровня наиболее жизнеопасных осложнений - кардиальных (острых форм ишемической болезни сердца, нарушений сердечного ритма), пульмональных (пневмоний, тромбоэмболии легочной артерии, респираторного дистресс-синдрома взрослых) и ренальных (острой почечной недостаточности). Некоторое исключение составили менее жизнеопасные тромботические осложнения. Полученные результаты имеют высокий уровень статистической значимости, что позволяет рекомендовать их к рассмотрению к использованию в практике сосудистой хирургии The article presents data from an original study to improve the surgical treatment of abdominal aortic aneurysms. For this purpose, a comparative analysis of two alternate operations was performed: 1) aneurysm resection followed by aortic prosthetics; 2) aortic endoprosthetics. The scientific hypothesis is formulated that the replacement of the «classical» operations of resection of the aneurysm with «alternative» operations of endoprosthetics will lead to a fundamental decrease in the level of postoperative complications. In independent groups of patients using the compared surgical interventions, an accurate qualitative and quantitative assessment of postoperative complications was made: non-thrombotic - cardiac, pulmonary, renal and thrombotic - deep vein thrombosis and prosthetic jaw thrombosis. After the study was completed, it was found that the fundamental replacement of «classical» operations with «alternative» reliably leads to a fundamental decrease in the level of the most life-threatening complications - cardiac (acute forms of coronary heart disease, cardiac arrhythmias), pulmonary (pneumonia, pulmonary thromboembolism, respiratory distress syndrome of adults) and renal (acute renal failure). Some exceptions were less life-threatening thrombotic complications. The results obtained have a high level of statistical significance, which allows us to recommend them for consideration in the practice of vascular surgery

Objective: The aim was to evaluate the efficacy and safety of duration of dual antiplatelet therapy (DAPT) for patients who received percutaneous coronary intervention (PCI) with a drug-eluting stent. Background: The optimal duration of DAPT to balance the risk of ischemia and bleeding in CAD patients undergoing drug-eluting stent (DES) implantation remains controversial. Methods: PubMed, Cochrane Library, Web of Science, Clinicaltrials.gov, CNKI and Wanfang Databases were searched for randomized controlled trials of comparing different durations of DAPT after DES implantation. Primary outcomes were major adverse cardiac and cerebrovascular events (MACCE), and major bleeding, and were pooled by Bayes network meta-analysis. Net adverse clinical and cerebral events were used to estimate the surface under the cumulative ranking (SUCRA) curves. The subgroup analysis based on clinical status, follow-up and area was conducted using traditional pairwise meta-analysis. Results: A total of nineteen trials (n=51,035) were included, involving six duration strategies. The network metaanalysis showed that T2 (<6-month DAPT followed by aspirin, HR:1.51, 95%CI:1.02-2.22), T3 (standard 6-month DAPT, HR:1.47, 95%CI:1.14-1.91), T4 (standard 12-month DAPT, HR:1.41, 95%CI:1.15-1.75) and T5 (18-24 months DAPT, HR:1.47, 95%CI:1.09-1.97) was associated with significantly increased risk of MACCE compared to T6 (>24-month DAPT). However, no significant difference was found in MACCE risk between T1 (<6-month DAPT followed by P2Y12 monotherapy) and T6. Moreover, T5 was associated with significantly increased risk of bleeding compared to T1(RR:3.94, 95%CI:1.66-10.60), T2(RR:3.65, 95%CI:1.32-9.97), T3(RR:1.93, 95%CI:1.21-3.50) and T4(RR:1.89, 95%CI:1.15-3.30). The cumulative probabilities showed that T6(85.0%), T1(78.3%) and T4(44.5%) were the most efficacious treatment compared to the other durations. In the ACS (<50%) subgroup, T1 was observed to significantly reduce the risk of major bleeding compared to T4, but not in the ACS (≥50%) subgroup. Conclusions: Compared with other durations, short DAPT followed by P2Y12 inhibitor monotherapy showed non-inferiority, with a lower risk of bleeding and not associated with an increased MACCE. In addition, the risk of major bleeding increased significantly, starting with DAPT for 18-month. Compared with the short-term treatment, patients with ACS with the standard 12-month treatment have a better prognosis, including lower bleeding rate and the decreased risk of MACCE. Due to study's limitations, the results should be verified in different risk populations.
