RESUMO

Background: Drug-eluting stents (DES) are considered the therapy of choice in ST-segment elevation myocardial infarction (STEMI); however, a low persistent rate of revascularizations and stent thrombosis exist over the time. We have previously shown that a paclitaxel (PTX)-drug-coated balloon (DCB) after a bare-metal stent (BMS) implantation (DCB-combined strategy) yields superior angiographic and clinical results compared to BMS in the short term. However, the long-term safety and efficacy of this approach remain uncertain. Methods: An 8-year clinical follow-up was conducted on patients enrolled in the randomized PEBSI-1 trial (NCT01839890). The original trial included patients who suffered a STEMI, patients were randomly assigned to receive a DCB-combined strategy or BMS only and the primary endpoint was in-stent late luminal loss (LLL) at 9-month follow-up. After the completion of this study, death, myocardial re-infarction, ischemia-driven repeated revascularizations included target lesion revascularization (TLR) and target vessel revascularization (TVR), and stent thrombosis, were assessed by yearly contact by a clinical visit, telephone or by electronic records. These outcomes were adhered to ARC-2 criteria. Results: The rate of incomplete follow-up was very low, with only 3 out of 111 patients (2.7%) in the DCB-combined strategy group and 1 out of 112 patients (0.9%) in the BMS group. At 8 years there were a lower rate of TVR [3.7% vs. 14.3%; hazard ratio (HR): 0.243; 95% confidence interval (CI): 0.081-0.727; P=0.006], and a trend towards lower TLR (2.8% vs. 8.9%; HR: 0.300; 95% CI: 0.083-1.090; P=0.052) in the DCB-combined strategy group. No statistical difference between the DCB-combined strategy and BMS groups were found for all causes of death, deaths from cardiovascular disease, reinfarctions or stent thrombosis. Notably in the DCB-combined strategy group, no episode of stent thrombosis occurred after the first year. Similarly, there were no cardiovascular deaths, TVR and TLR in the DCB-combined strategy group after 5 years. In contrast, during the period from year 5 to 8, the BMS group experienced an additional cardiovascular death, as well as one case of TVR, one case of TLR, and one case of stent thrombosis. Conclusions: In STEMI patients, the DCB-combined strategy maintains its safety and clinical efficacy over time. Our rates of TVR, TLR, and very late stent thrombosis (VLST) at very long-term are the lowest ever found in a STEMI trial. Further studies are warranted to assess the potential superiority of this novel strategy as compared with new-generation DES to prevent very late events in these patients.

RESUMO

INTRODUCTION AND OBJECTIVES: Transaxillary access (TXA) has become the most widely used alternative to transfemoral access (TFA) in patients undergoing transcatheter aortic valve implantation (TAVI). The aim of this study was to compare total in-hospital and 30-day mortality in patients included in the Spanish TAVI registry who were treated by TXA or TFA access. METHODS: We analyzed data from patients treated with TXA or TFA and who were included in the TAVI Spanish registry. In-hospital and 30-day events were defined according to the recommendations of the Valve Academic Research Consortium. The impact of the access route was evaluated by propensity score matching according to clinical and echocardiogram characteristics. RESULTS: A total of 6603 patients were included; 191 (2.9%) were treated via TXA and 6412 via TFA access. After adjustment (n=113 TXA group and n=3035 TFA group) device success was similar between the 2 groups (94%, TXA vs 95%, TFA; P=.95). However, compared with the TFA group, the TXA group showed a higher rate of acute myocardial infarction (OR, 5.3; 95%CI, 2.0-13.8); P=.001), renal complications (OR, 2.3; 95%CI, 1.3-4.1; P=.003), and pacemaker implantation (OR, 1.6; 95%CI, 1.01-2.6; P=.03). The TXA group also had higher in-hospital and 30-day mortality rates (OR, 2.2; 95%CI, 1.04-4.6; P=.039 and OR, 2.3; 95%CI, 1.2-4.5; P=.01, respectively). CONCLUSIONS: Compared with ATF, TXA is associated with higher total mortality, both in-hospital and at 30 days. Given these results, we believe that TXA should be considered only in those patients who are not suitable candidates for TFA.

RESUMO

OBJECTIVE: Left atrial appendage (LAA) thrombus has heretofore been considered a contraindication to percutaneous LAA closure (LAAC). Data regarding its management are very limited. The aim of this study was to analyse the medical and invasive treatment of patients referred for LAAC in the presence of LAA thrombus. METHODS: This multicentre observational registry included 126 consecutive patients referred for LAAC with LAA thrombus on preprocedural imaging. Treatment strategies included intensification of antithrombotic therapy (IAT) or direct LAAC. The primary and secondary endpoints were a composite of bleeding, stroke and death at 18 months, and procedural success, respectively. RESULTS: IAT was the preferred strategy in 57.9% of patients, with total thrombus resolution observed in 60.3% and 75.3% after initial and subsequent IAT, respectively. Bleeding complications and stroke during IAT occurred in 9.6% and 2.9%, respectively, compared with 3.8% bleeding and no embolic events in the direct LAAC group before the procedure. Procedural success was 90.5% (96.2% vs 86.3% in direct LAAC and IAT group, respectively, p=0.072), without cases of in-hospital thromboembolic complications. The primary endpoint occurred in 29.3% and device-related thrombosis was found in 12.8%, without significant difference according to treatment strategy. Bleeding complications at 18 months occurred in 22.5% vs 10.5% in the IAT and direct LAAC group, respectively (p=0.102). CONCLUSION: In the presence of LAA thrombus, IAT was the initial management strategy in half of our cohort, with initial thrombus resolution in 60% of these, but with a relatively high bleeding rate (~10%). Direct LAAC was feasible, with high procedural success and absence of periprocedural embolic complications. However, a high rate of device-related thrombosis was detected during follow-up.

RESUMO

INTRODUCTION AND OBJECTIVES: The COVID-19 outbreak has had an unclear impact on the treatment and outcomes of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess changes in STEMI management during the COVID-19 outbreak. METHODS: Using a multicenter, nationwide, retrospective, observational registry of consecutive patients who were managed in 75 specific STEMI care centers in Spain, we compared patient and procedural characteristics and in-hospital outcomes in 2 different cohorts with 30-day follow-up according to whether the patients had been treated before or after COVID-19. RESULTS: Suspected STEMI patients treated in STEMI networks decreased by 27.6% and patients with confirmed STEMI fell from 1305 to 1009 (22.7%). There were no differences in reperfusion strategy (> 94% treated with primary percutaneous coronary intervention in both cohorts). Patients treated with primary percutaneous coronary intervention during the COVID-19 outbreak had a longer ischemic time (233 [150-375] vs 200 [140-332] minutes, P < .001) but showed no differences in the time from first medical contact to reperfusion. In-hospital mortality was higher during COVID-19 (7.5% vs 5.1%; unadjusted OR, 1.50; 95%CI, 1.07-2.11; P < .001); this association remained after adjustment for confounders (risk-adjusted OR, 1.88; 95%CI, 1.12-3.14; P = .017). In the 2020 cohort, there was a 6.3% incidence of confirmed SARS-CoV-2 infection during hospitalization. CONCLUSIONS: The number of STEMI patients treated during the current COVID-19 outbreak fell vs the previous year and there was an increase in the median time from symptom onset to reperfusion and a significant 2-fold increase in the rate of in-hospital mortality. No changes in reperfusion strategy were detected, with primary percutaneous coronary intervention performed for the vast majority of patients. The co-existence of STEMI and SARS-CoV-2 infection was relatively infrequent.

RESUMO

INTRODUCTION AND OBJECTIVE: Major bleeding events in patients undergoing left atrial appendage closure (LAAC) range from 2.2 to 10.3 per 100 patient-years in different series. This study aimed to clarify the bleeding predictive factors that could influence these differences. METHODS: LAAC was performed in 598 patients from the Iberian Registry II (1093 patient-years; median, 75.4 years). We conducted a multivariate analysis to identify predictive risk factors for major bleeding events. The occurrence of thromboembolic and bleeding events was compared to rates expected from CHA2DS2-VASc (congestive heart failure, hypertension, age, diabetes, stroke history, vascular disease, sex) and HAS-BLED (hypertension, abnormal renal and liver function, stroke, bleeding, labile INR, elderly, drugs or alcohol) scores. RESULTS: Cox regression analysis revealed that age ≥75 years (HR: 2.5; 95% CI: 1.3 to 4.8; p = 0.004) and a history of gastrointestinal bleeding (GIB) (HR: 2.1; 95% CI: 1.1 to 3.9; p = 0.020) were two factors independently associated with major bleeding during follow-up. Patients aged <75 or ≥75 years had median CHA2DS2-VASc scores of 4 (IQR: 2) and 5 (IQR: 2), respectively (p < 0.001) and HAS-BLED scores were 3 (IQR: 1) and 3 (IQR: 1) for each group (p = 0.007). Events presented as follow-up adjusted rates according to age groups were stroke (1.2% vs. 2.9%; HR: 2.4, p = 0.12) and major bleeding (3.7 vs. 9.0 per 100 patient-years; HR: 2.4, p = 0.002). Expected major bleedings according to HAS-BLED scores were 6.2% vs. 6.6%, respectively. In patients with GIB history, major bleeding events were 6.1% patient-years (HAS-BLED score was 3.8 ± 1.1) compared to 2.7% patients-year in patients with no previous GIB history (HAS-BLED score was 3.4 ± 1.2; p = 0.029). CONCLUSIONS: In this high-risk population, GIB history and age ≥75 years are the main predictors of major bleeding events after LAAC, especially during the first year. Age seems to have a greater influence on major bleeding events than on thromboembolic risk in these patients.

RESUMO

BACKGROUND AND OBJECTIVE: Our aims were to improve the understanding of the pathogenic relationship between cardiovascular diseases and periodontitis and to generate new perspectives in the prevention and treatment of acute myocardial infarction (AMI) and periodontitis. The present study evaluates possible differences in inflammation, oxidative stress, and autophagy markers among subject suffering AMI, periodontitis, or both, to explore possible common pathogenic mechanisms. MATERIAL AND METHODS: A total of 260 subjects were enrolled in the study: 106 subjects that survived to a first AMI (AMI group) and 154 subjects had no cardiac events in their clinical record (control group). A questionnaire was used to assess age, height, weight, blood pressure, and heart rate. The clinical probing depth, clinical attachment loss, number of remaining teeth, and average number of sites with bleeding on probing were assessed. Lipid peroxidation and protein levels of phosphorylated AMP-activated protein kinase (p-AMPK) and microtubule-associated proteins 1A/1B-light chain 3-II (LC3-II) were determined in isolated peripheral blood mononuclear cells by thiobarbituric acid reactive substances (TBARS) assay and Western blot, respectively. Plasma levels of interleukin-1ß were determined using a commercial ELISA kit. All the obtained variables were compared between subjects suffering an AMI with or without periodontitis and control subject periodontal healthy or with periodontitis. RESULTS: A higher proportion of subjects suffering AMI + periodontitis than only AMI (without periodontitis) was found. Higher levels of TBARS were found in subjects with periodontitis than in subjects without periodontitis in both AMI and control subjects. Positive correlations between IL-1ß levels and TBARS and between IL-1ß levels and LC3-II were found only in control subjects. CONCLUSION: Results from the present study are consistent with the suggestion of periodontitis as a potential risk factor for AMI. Periodontitis association with circulating lipid peroxides in both AMI and control subjects were found. The absence of differences in IL-1ß levels between AMI subjects (only AMI vs AMI + periodontitis) suggests that oxidative stress could be the main pathogenic link between AMI and periodontitis.

RESUMO

Cell therapy is a progressively growing field that is rapidly moving from preclinical model development to clinical application. Outcomes obtained from clinical trials reveal the therapeutic potential of stem cell-based therapy to deal with unmet medical treatment needs for several disorders with no therapeutic options. Among adult stem cells, mesenchymal stem cells (MSCs) are the leading cell type used in advanced therapies for the treatment of autoimmune, inflammatory and vascular diseases. To date, the safety and feasibility of autologous MSC-based therapy has been established; however, their indiscriminate use has resulted in mixed outcomes in preclinical and clinical studies. While MSCs derived from diverse tissues share common properties depending on the type of clinical application, they markedly differ within clinical trials in terms of efficacy, resulting in many unanswered questions regarding the application of MSCs. Additionally, our experience in clinical trials related to critical limb ischemia pathology (CLI) shows that the therapeutic efficacy of these cells in different animal models has only been partially reproduced in humans through clinical trials. Therefore, it is crucial to develop new research to identify pitfalls, to optimize procedures and to clarify the repair mechanisms used by these cells, as well as to be able to offer a next generation of stem cell that can be routinely used in a cost-effective and safe manner in stem cell-based therapies targeting CLI.

RESUMO

Introducción y objetivos: Muchos pacientes con fibrilación auricular no valvular tienen contraindicados los anticoagulantes orales. El objetivo es estimar la incidencia de eventos tromboembólicos y hemorrágicos en pacientes con fibrilación auricular no valvular y cierre de la orejuela izquierda con seguimiento a largo plazo, y determinar los factores asociados con mayor mortalidad a largo plazo. Métodos: Cohorte prospectiva de pacientes reclutados desde 2009 a 2015. Se compararon los eventos tromboembólicos y hemorrágicos con los esperados según las escalas CHA2DS2-VASc y HAS-BLED. Se realizó un análisis multivariable para determinar las variables asociadas con la mortalidad. Resultados: Se reclutó a 598 pacientes (1.093 pacientes-año) con contraindicación de anticoagulantes (mediana de edad, 75,4 años). La tasa de éxito del cierre de la orejuela izquierda fue del 95,8%; 30 pacientes (5%) presentaron complicaciones. Las tasas de eventos (cada 100 pacientes-año) durante el seguimiento (media, 22,9 meses; mediana, 16,1 meses) fueron: muerte, 7,0%; ictus isquémico, 1,6% (frente al 8,5% esperado según CHA2DS2-VASc; p < 0,001); hemorragia intracraneal, 0,8%; hemorragia gastrointestinal, 3,2%, y hemorragia grave, 3,9% (frente al 6,3% esperado por HAS-BLED; p = 0,002). Estos resultados incluso mejoraron en el subgrupo de 176 pacientes con seguimiento > 24 meses (media, 46,6 meses; 683 pacientes-año) para las hemorragias graves, el 2,6% (frente al 6,3% esperado por HAS-BLED; p < 0,033). La edad (HR = 1,1), las hemorragias intracraneales (HR = 6,8) y el ictus (HR = 2,7) se asociaron con mayor mortalidad. Conclusiones: El cierre de la orejuela izquierda redujo significativamente las incidencias de ictus y de eventos hemorrágicos graves y el beneficio se mantuvo. La edad, las hemorragias intracraneales y el ictus se asociaron con mayor mortalidad


Introduction and objectives: Many patients with nonvalvular atrial fibrillation are still left without protection due to a contraindication for anticoagulants. This study aimed to establish the occurrence of stroke and major bleeding events in patients with nonvalvular atrial fibrillation and left atrial appendage closure with long-term follow-up and to explore the factors associated with higher long-term mortality. Methods: Analysis of a multicenter single cohort prospectively recruited from 2009 to 2015. Thromboembolic and bleeding events were compared with those expected from CHA2DS2-VASc and HAS-BLED scores. Multivariate analysis examined variables associated with mortality during follow-up. Results: A total of 598 patients (1093 patient-years) with a contraindication for anticoagulants were recruited (median 75.4 years). The success rate of left atrial appendage closure device implantation was 95.8%. Thirty patients (5%) experienced periprocedural complications. The rate of events (per 100 patient-years) during follow-up (mean 22.9 months; median 16.1 months) was as follows: death 7.0%; ischemic stroke 1.6% (vs 8.5% expected according to CHA2DS2-VASc; P < .001); intracranial hemorrhage 0.8%; gastrointestinal bleeding 3.2%; severe bleeding 3.9% (vs 6.3% expected by HAS-BLED, P = .002). These results were improved in the subgroup of 176 patients with follow-up > 24 months (mean follow-up 46.6 months, 683 patient-years) for severe bleeding 2.6% (vs 6.3% expected by HAS-BLED, P < .033). The factors significantly associated with higher mortality were age (HR, 1.1), intracranial hemorrhage (HR, 6.8), and stroke during follow-up (HR, 2.7). Conclusions: Left atrial appendage closure significantly reduced the incidence of stroke and bleeding events and the benefit was maintained. Intracranial hemorrhage, age and stroke were associated with higher mortality

RESUMO

BACKGROUND: Stroke recurrence despite optimal oral anticoagulation (OAC) might represent a novel indication for left atrial appendage occlusion (LAAO). The heterogeneity of these patients is generally high, as the presence of valvular atrial fibrillation (VAF) is common. The aim of this study was to explore the role of LAAO as an adjunctive therapy to OAC in patients with recurrent stroke despite optimal OAC. METHODS: The study screened consecutive patients who underwent percutaneous LAAO at nine centers between 2009 and 2017. Patients with recurrent stroke despite optimal OAC were selected and those with an absolute or relative contraindication to OAC were not included in the study. RESULTS: Among 837 patients who underwent LAAO between the study period, a total of 22 (2.6%) met the inclusion criteria. There was a high percentage of VAF (38%) and 59% presented more than one cardioembolic event before LAAO. All patients underwent successful implantation of the device and no procedural major adverse events were reported. In all but 3 patients, anticoagulation was continued after LAAO. With a median clinical follow-up of 1.8 years (range, 0.7-2.8 years), only 1 stroke and 1 transient ischemic attack were reported, translating into a significant reduction of cerebrovascular events before and after LAAO (2.0 ± 1.0 events vs 0.1 ± 0.3 events; P<.01). Imaging follow-up revealed only 1 case of device thrombosis. CONCLUSIONS: LAAO as an adjunctive therapy to OAC seems to be feasible and safe in patients with previous cardioembolic events despite optimal OAC. In our series, this strategy was associated with a low rate of cerebrovascular events after LAAO.

RESUMO

Diabetes is a chronic metabolic disorder that affects 415 million people worldwide. This pathology is often associated with long-term complications, such as critical limb ischemia (CLI), which increases the risk of limb loss and mortality. Mesenchymal stromal cells (MSCs) represent a promising option for the treatment of diabetes complications. Although MSCs are widely used in autologous cell-based therapy, their effects may be influenced by the constant crosstalk between the graft and the host, which could affect the MSC fate potential. In this context, we previously reported that MSCs derived from diabetic patients with CLI have a defective phenotype that manifests as reduced fibrinolytic activity, thereby enhancing the thrombotic risk and compromising patient safety. Here, we found that MSCs derived from diabetic patients with CLI not only exhibit a prothrombotic profile but also have altered multi-differentiation potential, reduced proliferation, and inhibited migration and homing to sites of inflammation. We further demonstrated that this aberrant cell phenotype is reversed by the platelet-derived growth factor (PDGF) BB, indicating that PDGF signaling is a key regulator of MSC functionality. These findings provide an attractive approach to improve the therapeutic efficacy of MSCs in autologous therapy for diabetic patients.

RESUMO

Conventional cardiovascular risk factors (CVRFs) are accepted to identify asymptomatic individuals with high risk of acute myocardial infarction (AMI). However, AMI affects many patients previously classified at low risk. New biomarkers are needed to improve risk prediction. We propose to evaluate the NLRP3-inflammasome complex as a potential conventional cardiovascular risk (CVR) indicator in healthy males and post-AMI patients and compare both groups by known CVRFs. We included 109 men with no history of cardiovascular disease (controls) and 150 AMI patients attending a cardiac rehabilitation program. AMI patients had higher mean of body mass index (BMI) and waist circumference than the controls. However, high percentages of the controls had a high BMI and a waist circumference >95 cm. The controls also had higher systolic blood pressure (p > 0.001), total and low-density lipoprotein cholesterol, dietary nutrient, and calorific intake. Fuster BEWAT score (FBS) correlated more closely than Framingham risk score (FRS) with most CVRF, groups. However, only the FBS showed a correlation with inflammasome cytokine interleukin 1ß (IL-1ß). Several CVRFs were significantly better in AMI patients; however, this group also had higher mRNA expression of the inflammasome gene NLRP3 and lower expression of the autophagy gene MAP-LC3. The controls had high levels of CVRF, probably reflecting unhealthy lifestyle. FBS reflects the efficiency of strategies to induce lifestyle changes such as cardiac rehabilitation programs, and could provide a sensitive evaluation CVR. These results lead to the hypothesis that NLRP3-inflammasome and associated IL-1ß release have potential as CVR biomarkers, particularly in post-AMI patients with otherwise low risk scores. Antioxid.

RESUMO

AIMS: Our aim was to assess the safety and efficacy of paclitaxel-eluting balloon (PTX-B) treatment after bare metal stent (BMS) implantation in patients undergoing primary angioplasty. METHODS AND RESULTS: After BMS implantation, patients were randomised (1:1) to treatment with a PTX-B or no PTX-B treatment (BMS group). The primary endpoint was in-stent late luminal loss (LLL) at nine-month follow-up. OCT was carried out on the first 20% of consecutive patients included in the study. Two hundred and twenty-three patients were randomised (BMS: 112, PTX-B: 111). At nine months, median LLL was 0.80 mm (interquartile range [IQR] 0.36-1.26) in the BMS group vs. 0.31 mm (IQR 0.00-0.58) in the PTX-B group, p<0.0001. Binary restenosis was significantly lower in the PTX-B group: 29.8% vs. 2.2%, p<0.0001, 95% confidence interval (CI): 3.2-54.2. Nine-month OCT showed good strut coverage in both groups but greater in the BMS group (100±0.0% vs. 99.52±1.11%, p=0.03) with very low rates of malapposed struts per lesion. One-year MACE was significantly lower in the PTX-B group (12.5% vs. 3.6%, p=0.016). CONCLUSIONS: PTX-B after successful BMS implantation resulted in less LLL and better clinical outcomes as compared with a BMS-only strategy. This was associated with good stent strut coverage and very low rates of malapposed struts.

RESUMO

Objetivo: determinar la seguridad y la eficacia de la embolización uterina por vía transradial en el tratamiento de las pacientes con miomas sintomáticos. Diseño del estudio: estudio prospectivo realizado en una institución terciaria. 64 pacientes con miomas sintomáticos fueron tratadas mediante embolización por vía transradial. Se realizaron controles previos, al mes y al semestre del procedimiento. Resultados: se completó la embolización de las dos arterias uterinas en 62 pacientes (97%), con una duración media del procedimiento de 87,5 ± 39, 1 minutos. No hubo ninguna complicación local en el acceso vascular. Respecto a la eficacia, se demostró un aumento medio de la hemoglobina desde 10,95 g/dL antes del tratamiento hasta 12,56 g/dL, después del mismo. Igualmente, se produjo una mejoría de la calidad de vida de las pacientes, con un descenso significativo de la puntuación al semestre de la embolización (85,84 ± 29,27 previa, 27,00 ± 22,45 a los 6 meses). Se produjo reingreso precoz en el 14% de las pacientes, por dolor y finalmente se operaron 3 pacientes (4,69%) por no haber mejorado de sus síntomas Conclusión: la embolización uterina transradial es segura y tan efectiva para el tratamiento de los miomas como la transfemoral (AU)


Objective: To determine the safety and efficacy of uterine fibroid embolisation using the transradial approach. Study design: This prospective study was conducted at a tertiary institution. Sixty-four patients with symptomatic uterine fibroids underwent fibroid embolisation using the transradial approach. The patients were assessed before the procedure and 1 and 6 months after the procedure. Results: Embolisation via both uterine arteries was achieved in 62 of the 64 patients (97%), with a mean procedure time of 87.5 ± 39.1 min. Objective assessment showed an increase in the haemoglobin concentration from 10.95 g/dL before the procedure to 12.56 g/dL after 6 months, and a 42% decrease in the volume of the largest fibroid after 6 months. Subjective assessment showed a significant improvement in the quality of life score from 85.84 ± 29.27 before the procedure to 27.00 ± 22.45 after 6 months. There were no vascular complications related to the transradial access. Early readmission was required in 14% of patients due to pain. Three patients (4.69%) underwent subsequent hysterectomy because their symptoms did not improve after the embolisation procedure. Conclusion: Uterine fibroid embolisation using the transradial approach is safe and is as effective as using the transfemoral approach (AU)

RESUMO

Vascular complications in transcatheter aortic valve implantation using transfemoral approach are related to higher mortality. Complete percutaneous approach is currently the preferred technique for vascular access. However, some centers still perform surgical cutdown. Our purpose was to determine complications related to vascular access technique in the population of the Spanish TAVI National Registry. From January 2010 to July 2015, 3,046 patients were included in this Registry. Of them, 2,465 underwent transfemoral approach and were treated with either surgical cutdown and closure (cutdown group, n = 632) or percutaneous approach (puncture group, n = 1,833). Valve Academic Research Consortium-2 definitions were used to assess vascular and bleeding complications. Propensity matching resulted in 615 matched pairs. Overall, 30-day vascular complications were significantly higher in the puncture group (109 [18%] vs 42 [6.9%]; relative risk [RR] 2.60; 95% confidence interval [CI] 1.85 to 3.64, p <0.001) due mostly by minor vascular events (89 [15%] vs 25 [4.1%], RR 3.56, 95% CI 2.32 to 5.47, p <0.001). Bleeding rates were lower in the puncture group (18 [3%] vs 40 [6.6%], RR 0.45, 95% CI 0.26 to 0.78, p = 0.003) mainly driven by major bleeding (9 [1.5%] vs 21 [3.4%], RR 0.43, 95% CI 0.20 to 0.93, p = 0.03). At a mean follow-up of 323 days, complication rates remained significantly different between groups (minor vascular complications 90 [15%] vs 31 [5.1%], hazard ratio 2.99, 95% CI 1.99 to 4.50, p <0.001 and major bleeding 10 [1.6%] vs 21 [3.4%], hazard ratio 0.47, 95% CI 0.22 to 1.0, p = 0.04, puncture versus cutdown group, respectively). In conclusion, percutaneous approach yielded higher rates of minor vascular complications but lower rates of major bleeding compared with the surgical cutdown, both at 30-day and at mid-term follow-up in our population.
