Spontaneous coronary artery dissection (SCAD) and takotsubo cardiomyopathy (TCM) - A potential association.

Background: Spontaneous coronary artery dissection and takotsubo cardiomyopathy are increasingly recognized in the last two decades. Case reports have shown both entities can present concomitantly - however, little is known about their association. Methods: In this retrospective study we aimed to explore a potential association between SCAD and TCM using the Nationwide Inpatient Sample. The odds of having TCM among patients with SCAD compared with those who did not have SCAD were calculated as an odds ratio. Conversely, the odds of having SCAD among patients with TCM compared with those who did not have TCM were also calculated. The primary outcome was the odds of TCM among patients with a primary diagnosis of SCAD and vice versa. The secondary endpoint was the odds of in-hospital mortality among patients with SCAD, and/or TCM. Results: Hospitalized patients who had SCAD were 7.12 (95 % CI: 6.28-8.08) times more likely to also have TCM than those who did not have SCAD (p < 0.0001).), while patients with TCM were 6.91 (95 % CI: 6.07-7.85) times more likely to have SCAD compared to those who didn't have TCM adjusted for age, gender, race, hypertension, hyperlipidemia, and diabetes mellitus (p < 0.0001). Conclusion: This data indicate that patients with either SCAD or TCM are seven times more likely to be diagnosed concomitantly with both, compared to the patients without either diagnosis [after adjusting for age, gender, race, hypertension, hyperlipidemia, and diabetes mellitus]. Our data are consistent with the growing body of evidence supporting an association between SCAD and TCM and raise the question of a common pathophysiologic mechanism.

Association of Hospital Procedural Volume With Outcomes of Left Ventricular Assist Device Placement.

BACKGROUND: With the advancement in device technology, the use of durable left ventricular assist devices (LVADs) has increased significantly in recent years. However, there is a dearth of evidence to conclude whether patients who undergo LVAD implantation at high-volume centers have better clinical outcomes than those receiving care at low- or medium-volume centers. METHODS: We analyzed the hospitalizations using the Nationwide Readmission Database for the year 2019 for new LVAD implantation. Baseline comorbidities and hospital characteristics were compared among low- (1-5 procedures/year), medium- (6-16 procedures/year) and high-volume (17-72 procedures/year) hospitals. The volume/outcome relationship was analyzed using the annualized hospital volume as a categorical variable (tertiles) as well as a continuous variable. Multilevel mixed-effect logistic regression and negative binomial regression models were used to determine the association of hospital volume and outcomes, with tertile 1 (low-volume hospitals) as the reference category. RESULTS: A total of 1533 new LVAD procedures were included in the analysis. The inpatient mortality rate was lower in the high-volume centers compared with the low-volume centers (9.04% vs 18.49%, aOR 0.41, CI0.21-0.80; P = 0.009). There was a trend toward lower mortality rates in medium-volume centers compared with low-volume centers; however, it did not reach statistical significance (13.27% vs 18.49%, aOR 0.57, CI0.27-1.23; P = 0.153). Similar results were seen for major adverse events (composite of stroke/transient ischemic attack and in-hospital mortality). There was no significant difference in bleeding/transfusion, acute kidney injury, vascular complications, pericardial effusion/hemopericardium/tamponade, length of stay, cost, or 30-day readmission rates between medium- and high-volume centers compared to low-volume centers. CONCLUSION: Our findings indicate lower inpatient mortality rates in high-volume LVAD implantation centers and a trend toward lower mortality rates in medium-volume LVAD implantation centers compared to lower-volume centers.

Acute Pancreatitis and Myocardial Infarction: A Narrative Review.

BACKGROUND: Acute pancreatitis can rarely present with electrocardiographic changes that imitate myocardial ischemia. Even rarer is for acute pancreatitis to present with ST segment elevation in contiguous leads, suggestive of an acute coronary syndrome. In this comprehensive review article, we highlight diagnostic challenges and examine possible pathophysiological causes as seen through 34 total cases in which acute pancreatitis has been found to mimic an acute myocardial infarction. SUMMARY: It has been shown that regardless of the severity of acute pancreatitis, it can be associated with myocardial injury of varying presentation. Thus far, there have been 34 total cases where acute pancreatitis presented with electrocardiographic changes consistent with acute myocardial infarction without true coronary artery thrombosis. An inferior wall ST-elevation myocardial infarction pattern was the most frequently demonstrated. Many hypotheses have been proposed as to the mechanism of injury including decreased coronary perfusion, direct myocyte damage by pancreatic proteolytic enzymes, indirect parasympathetic injury, electrolyte derangements, and coronary vasospasms. Given the complexity of the clinical presentation, thorough subjective and objective evaluation can be vital in guiding to diagnosis and possibly more invasive testing. KEY MESSAGES: It is imperative that clinicians are aware that acute pancreatitis can mimic an acute myocardial infarction. Although we have started to better understand the pathological mechanisms for this phenomenon, further research focused on specific molecular target areas is needed.

Gender Parity in High Impact Cardiology Journals.

Despite increased female representation in medical training, women physicians continue to be under-represented in academic cardiology, particularly in senior roles of authorship and leadership. We analyzed the top 20 most-cited cardiology journals (31,540 total articles) between January 1, 2018 and October 31, 2021 for gender distribution of editorial staff and authorship. Our data demonstrated that only 27% of articles had women as first authors and 20% as senior authors. Women constituted 23% of editorial staff. There is a statistically significant negative correlation (R = 0.67, P = 0.0011) between the percentage of women as first authors and the percentage of men on editorial boards. Overall, female authorship increased from 26% first and 19% senior authors in 2018, to 29% first and 22% senior authors in 2021. Women authors are significantly under-represented in academic cardiology publications, and additional work is needed to identify and address barriers to publishing and academic advancement for women in cardiology.

Nationwide Analysis of the Clinical Outcomes of Patients Admitted With COVID-19 Infection With Myocarditis and Racial Disparities in Mortality.

Coronavirus-19 (COVID-19), while primarily a respiratory virus, affects multiple organ systems, including the cardiovascular system. The relationship between COVID-19 and Myocarditis has been well established, but there are limited large-scale studies evaluating outcome of COVID-19 related Myocarditis. Using National Inpatient Sample (NIS) database, we compared patients with Myocarditis with and without COVID-19 infection. The primary outcome was in-hospital mortality. Secondary outcomes were acute kidney injury requiring hemodialysis, vasopressor use, mechanical ventilation, cardiogenic shock, mechanical circulatory support, sudden cardiac arrest, and length of hospitalization. A total of 17,970 patients were included in study; Myocarditis without COVID (n = 11,515, 64%) and Myocarditis with COVID-19 (n = 6,455, 36%). Patients with COVID-19 and Myocarditis had higher in-hospital mortality compared to those with Myocarditis alone (30.7% vs 6.4%, odds ratio 4.8, 95% CI 3.7-6.3, P< 0.001). That cohort also had significantly higher rates of vasopressor use, mechanical ventilation, sudden cardiac arrest, and acute kidney injury requiring hemodialysis. Given the poor outcome seen in COVID-19 related Myocarditis cohort, further work is needed for development of directed therapies for COVID-19-related Myocarditis.

National Trends and Outcomes of Tricuspid Valve Surgery with Concomitant Mitral Valve Surgery: Results From a Ten-year Analysis of the National Inpatient Sample Database.

According to an estimate, 20% of patients with heart valve disease have multivalve involvement necessitating combined valve surgery. There is a dearth of data about the clinical outcomes of patients with combined mitral and tricuspid valve disease who go through tricuspid valve surgery with concomitant mitral valve replacement or repair. We utilized National Inpatient Sample (NIS) between January 1, 2004, and December 31, 2014, to analyze the outcomes of patients who underwent tricuspid valve surgery with either mitral valve replacement or repair. We identified 21,141 weighted hospitalizations for combined TVS with MVr (TVS/MVr) or TVS with MVR (TVS/MVR). The overall inpatient mortality in the TVS/MVR cohort was higher than in the TVS/MVr cohort (7.36% vs 5.33%, P < 0.01). There was a trend toward decreased mortality over the years in the TVS/MVr cohort (P = 0.04) while mortality remained unchanged in the TVS/MVR cohort (P = 0.88). Overall, the TVS/MVr cohort had better clinical outcomes profile compared with TVS/MVR cohort.

Comparison of Suture-Based and Collagen-Based Vascular Closure Devices for Large Bore Arteriotomies-A Meta-Analysis of Bleeding and Vascular Outcomes.

BACKGROUND: Large bore access procedures rely on vascular closure devices to minimize access site complications. Suture-based vascular closure devices (S-VCD) such as ProGlide and ProStar XL have been readily used, but recently, newer generation collagen-based vascular closure devices (C-VCD) such as MANTA have been introduced. Data on comparisons of these devices are limited. METHODS: PubMed, Scopus and Cochrane were searched for articles on vascular closure devices using keywords, ("Vascular closure devices" OR "MANTA" OR "ProStar XL" OR "ProGlide") AND ("outcomes") that resulted in a total of 875 studies. Studies were included if bleeding or vascular complications as defined by Valve Academic Research Consortium-2 were compared between the two types of VCDs. The event level data were pooled across trials to calculate the Odds Ratio (OR) with 95% CI, and analysis was done with Review Manager 5.4 using random effects model. RESULTS: Pooled analyses from these nine studies resulted in a total of 3410 patients, out of which 2855 were available for analysis. A total of 1229 received C-VCD and 1626 received S- VCD. Among the patients who received C-VCD, the bleeding complications (major and minor) were similar to patients who received S-VCD ((OR: 0.70 (0.35-1.39), p = 0.31, I2 = 55%), OR: 0.92 (0.53-1.61), p = 0.77, I2 = 65%)). The vascular complications (major and minor) in patients who received C-VCD were also similar to patients who received S-VCD ((OR: 1.01 (0.48-2.12), p = 0.98, I2 = 52%), (OR: 0.90 (0.62-1.30), p = 0.56, I2 = 35%)). CONCLUSIONS: Bleeding and vascular complications after large bore arteriotomy closure with collagen-based vascular closure devices are similar to suture-based vascular closure devices.

Declining Trend of Transapical Access for Transcatheter Aortic Valve Replacement in Patients with Aortic Stenosis.

Introduction: The last decade has witnessed major evolution and shifts in the use of transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). Included among the shifts has been the advent of alternative access sites for TAVR. Consequently, transapical access (TA) has become significantly less common. This study analyzes in detail the trend of TA access for TAVR over the course of 7 years. Methods: The national inpatient sample database was reviewed from 2011-2017 and patients with AS were identified by using validated ICD 9-CM and ICD 10-CM codes. Patients who underwent TAVR through TA access were classified as TA-TAVR, and any procedure other than TA access was classified as non-TA-TAVR. We compared the yearly trends of TA-TAVR to those of non-TA-TAVR as the primary outcome. Results: A total of 3,693,231 patients were identified with a diagnosis of AS. 129,821 patients underwent TAVR, of which 10,158 (7.8%) underwent TA-TAVR and 119,663 (92.2%) underwent non-TA-TAVR. After peaking in 2013 at 27.7%, the volume of TA-TAVR declined to 1.92% in 2017 (p < 0.0001). Non-TA-TAVR started in 2013 at 72.2% and consistently increased to 98.1% in 2017. In-patient mortality decreased from a peak of 5.53% in 2014 to 3.18 in 2017 (p=0.6) in the TA-TAVR group and from a peak of 4.51% in 2013 to 1.24% in 2017 (p=0.0001) in the non-TA-TAVR group. Conclusion: This study highlights a steady decline in TA access for TAVR, higher inpatient mortality, increased length of stay, and higher costs compared to non-TA-TAVR.

Clinical Outcomes of Transcatheter Aortic Valve Replacement (TAVR) Vs. Surgical Aortic Valve Replacement (SAVR) in Patients With Durable Left Ventricular Assist Device (LVAD).

Patients with left ventricular assist device (LVAD) often develop aortic insufficiency requiring an intervention on the aortic valve. We sought to analyze the outcomes of patients with a history of LVAD who underwent either transcatheter aortic valve replacement or surgical aortic valve replacement. The Nationwide Readmission Database was used to extract relevant patient information from January 1, 2016, to December 31, 2018. The Nationwide Readmission Database is a nationally representative sample of all-payer discharges from United States nonfederal hospitals. The primary outcome of interest was in-hospital mortality. Secondary outcomes included length of stay, clinical outcomes, costs, and 30-day all-cause readmissions. Complex samples multivariable logistic and linear regression models were used to determine the association of procedure type with outcomes. Among 148 hospitalizations with a history of LVAD, 87 underwent transcatheter aortic valve replacement (TAVR), and 61 underwent surgical aortic valve replacement (SAVR). The inpatient mortality in SAVR group was numerically higher compared to the TAVR cohort, however, it did not reach statistical significance. The use of invasive mechanical ventilation, and rates of cardiogenic shock, bleeding, and vascular complications were higher in the SAVR cohort compared to the TAVR cohort. The mean length of stay and costs were higher in the SAVR cohort compared to the TAVR cohort. The 30-day all-cause readmission rate was numerically higher in the SAVR group but not statistically significant. TAVR in patients with LVAD may be a viable treatment option for patients with AI with potential for better inpatient mortality and inpatient outcomes compared to patients who undergo SAVR in appropriately selected patients.

Hypertension as an Independent Risk Factor for In-Patient Mortality in Hospitalized COVID-19 Patients: A Multicenter Study.

Despite the lack of direct evidence that hypertension increases the likelihood of new infections, hypertension is known to be the most common comorbid condition in COVID-19 patients and also a major risk factor for severe COVID-19 infection. The literature review suggests that data is heterogeneous in terms of the association of hypertension with mortality. Hence, it remains a topic of interest whether hypertension is associated with COVID-19 disease severity and mortality. Herein, we perform a multicenter retrospective analysis to study hypertension as an independent risk for in-hospital mortality in hospitalized COVID-19 patients. This multicenter retrospective analysis included 515 COVID-19 patients hospitalized from March 1, 2020 to May 31, 2020. Patients were divided into two groups: hypertensive and normotensive. Demographic characteristics and laboratory data were collected, and in-hospital mortality was calculated in both groups. The overall mortality of the study population was 25.3% (130 of 514 patients) with 96 (73.8%) being hypertensive and 34 (26.2%) being normotensive (p-value of 0.01, statistically non-significant association). The mortality rate among the hypertensive was higher as compared to non-hypertensive; however, hypertensive patients were more likely to be old and have underlying comorbidities including obesity, diabetes mellitus, coronary artery disease, congestive heart failure, stroke, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), and cancer. Therefore, multivariable logistic regression failed to show any significant association between hypertension and COVID-19 mortality. To our knowledge, few studies have shown an association between hypertension and COVID-19 mortality after adjusting confounding variables. Our study provides further evidence that hypertension is not an independent risk factor for in-hospital mortality when adjusted for other comorbidities in hospitalized COVID-19 patients.

Drug-eluting Stents Versus Bare-metal Stents for Saphenous Vein Graft Interventions: A Systematic Review and Meta-analysis of Studies With Longer Follow-up.

Randomized controlled trials comparing drug eluting stents (DES) with bare-metal stents (BMS) for saphenous vein graft (SVG) interventions have shown conflicting results. We conducted this meta-analysis to evaluate the cumulative evidence for long-term efficacy and safety of DES vs BMS in SVG lesions. A systematic search was conducted of Randomized controlled trials comparing DES vs BMS in patients undergoing percutaneous interventions for SVG lesions. End-points of interest were all-cause death, cardiac death, myocardial infarction, target lesion revascularization and target vessel revascularization at longest available follow-up. Random effects meta-analysis was conducted to estimate risk ratio with 95% confidence intervals for individual end-points. Seven studies with 1639 patients were included in the final analysis. Mean follow-up period was 32 months. Compared with BMS, DES was associated with similar risks of all-cause death (risk ratio 1.06; 95% confidence intervals 0.76-1.48) and cardiac death (0.95; 0.59-1.54). Similarly, there were no differences between DES and BMS in terms of myocardial infarction (0.81; 0.50-1.29), target vessel revascularization (0.73; 0.48-1.110 or target lesion revascularization (1.05; 0.76-1.43). Current analysis suggests no strong evidence for routine DES use in patients undergoing SVG intervention. Future studies should evaluate if SVG lesion characteristics could influence these results.

Intravascular Lithotripsy Enabled Transfemoral Transcatheter Aortic Valve Implantation via Percutaneous Axillary Access Approach.

Transfemoral (TF) access for transcatheter aortic valve implantation (TAVI) is the most commonly used site, however its use may be limited by prohibitive peripheral arterial disease. Although a number of alternative access techniques have been well described, each has been shown to be associated with increased risks when compared to a TF approach. Recently, planned treatment of iliofemoral artery disease using intravascular lithotripsy (IVL) has emerged as a means of preserving TF access. Ipsilateral or contralateral femoral artery access has been routinely used to perform IVL but its use may be limited in certain conditions. Here we describe the novel technique of using percutaneous axillary artery access to perform IVL of iliofemoral artery to facilitate its use for large bore access. We present a 78-year-old high surgical risk female with severe aortic stenosis who was found to have a prior stent in the contralateral iliac artery protruding into the aorta which limited a traditional 'up and over' approach, and thus axillary artery access was used to perform IVL. This is the first case in literature to describe the use of percutaneous axillary access to perform IVL of the iliac and common femoral artery to facilitate TF TAVI. Based on our previous experience we feel this technique holds promise for a routine use when use of other access sites is limited.

Efficacy of Manual Hemostasis for Percutaneous Axillary Artery Intra-Aortic Balloon Pump Removal.

BACKGROUND: The prevalence of peripheral vascular disease has led to the re-emergence of percutaneous axillary vascular access as a suitable alternative access site to femoral artery. We sought to investigate the efficacy and safety of manual hemostasis in the axillary artery. METHODS: Data were collected from a prospective internal registry of patients who had a Maquet® (Rastatt, Germany) Mega 50 cc intra-aortic balloon pumps (IABP) placed in the axillary artery position. They were anticoagulated with weight-based intravenous heparin to maintain an activated partial thromboplastin time (aPTT) of 50-80 seconds. Anticoagulation was discontinued 2 hours prior to the device explantation. Manual compression was used to achieve the hemostasis of the axillary artery. Vascular and bleeding complications attributable to manual hemostasis were classified based on the Valve Academic Research Consortium-2 (VARC-2) and Bleeding Academic Research Consortium-2 (BARC-2) classifications, respectively. RESULTS: 29 of 46 patients (63%) achieved axillary artery homeostasis via manual compression. The median duration of IABP implantation was 12 days (range 1-54 days). Median compression time was 20 minutes (range 5-60 minutes). There were no major vascular or bleeding complications as defined by the VARC-2 and BARC-2 criteria, respectively. CONCLUSION: Manual compression of the axillary artery appears to be an effective and safe method for achieving hemostasis. Large prospective randomized control trials may be needed to corroborate these findings.

Adverse Events After Left Atrial Appendage Closure: Lessons Learned From the Manufacturer and User Facility Device Experience (MAUDE) Database.

Left atrial appendage (LAA) closure devices are alternative treatments recently approved for patients with atrial fibrillation. Due to the novelty of these devices, limited postapproval surveillance data on LAA closure devices have been published. Thus, we analyzed the United States Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) database to report these findings. The primary endpoint was final event outcome, and secondary endpoints included management strategies of reported events.

Prioritizing elective cardiovascular procedures during the COVID-19 pandemic: The cardiovascular medically necessary, time-sensitive procedure scorecard.

BACKGROUND: Following the surge of the coronavirus disease 2019 (COVID-19) pandemic, government regulations, and recommendations from professional societies have conditioned the resumption of elective surgical and cardiovascular (CV) procedures on having strategies to prioritize cases because of concerns regarding the availability of sufficient resources and the risk of COVID-19 transmission. OBJECTIVES: We evaluated the use of a scoring system for standardized triage of elective CV procedures. METHODS: We retrospectively reviewed records of patients scheduled for elective CV procedures that were prioritized ad hoc to be either performed or deferred when New Jersey state orders limited the performance of elective procedures due to the COVID-19 pandemic. Patients in both groups were scored using our proposed CV medically necessary, time-sensitive (MeNTS) procedure scorecard, designed to stratify procedures based on a composite measure of hospital resource utilization, risk of COVID-19 exposure, and time sensitivity. RESULTS: A total of 109 scheduled elective procedures were either deferred (n = 58) or performed (n = 51). The median and mean cumulative CV MeNTS scores for the group of performed cases were significantly lower than for the deferred group (26 (interquartile range (IQR) 22-31) vs. 33 (IQR 28-39), p < .001, and 26.4 (SE 0.34) vs. 32.9 (SE 0.35), p < .001, respectively). CONCLUSIONS: The CV MeNTS procedure score was able to stratify elective cases that were either performed or deferred using an ad hoc strategy. Our findings suggest that the CV MeNTS procedure scorecard may be useful for the fair triage of elective CV cases during the time when available capacity may be limited due to the COVID-19 pandemic.

Role of Intravascular Ultrasound in Managing a Rare Case of Delayed Stent Deformity.

Delayed stent deformity is a very rare complication. We attempted to dilate the lumen within the crushed stent, but were unsuccessful even after laser atherectomy. At this point, we opted to place a new stent within the deformed old stent. In this case, intravascular ultrasound was extremely useful in guiding its diagnosis and management.

Implications of Misclassification of Type 2 Myocardial Infarction on Clinical Outcomes.

BACKGROUND: Patients with type 2 myocardial infarction (MI) are often classified under the diagnosis of non-ST-segment-elevation MI (NSTEMI) despite the significant differences in clinical characteristics, management, and outcomes between type 2 MI and type 1 NSTEMI. This may have significant implications that can lead to inaccurate assessment of quality measures by MI quality review programs. METHODS: A single-center retrospective study of 1224 patients discharged with the diagnosis of type 1 NSTEMI between January 2015 and September 2017. Based on the third universal definition of MI, we stratified patients into type 2 MI or type 1 NSTEMI. Patient's characteristics, comorbidities, medications prescribed during hospitalization and at discharge, readmissions within 30 days after discharge, and diagnostic and therapeutic interventions data was collected. The primary goal of this study was to identify how often type 2 MI patients were misclassified as type 1 NSTEMI, we also assessed the differences in treatment and outcomes between type 2 MI and type 1 NSTEMI. RESULTS: 1224 patients assigned the ICD-9 and ICD-10 codes of type 1 NSTEMI at discharge were evaluated for study inclusion. After application of the inclusion criteria, 945 patients were included in the final analysis. Of these 945 patients, 281 (29.7%) patients were classified as type 2 MI and 664 (70.3%) patients were classified as type 1 NSTEMI. Patients with type 2 MI were older, more likely to have systolic heart failure, had lower peak troponin levels, were less likely to receive aspirin, P2Y12 inhibitors and statin at discharge, and had longer length of stay. Compared with type 1 NSTEMI patients, those with type 2 MI had higher all cause 30-day mortality (13.5% versus 2.9%, P < 0.0001) (RR: 4.65; 95% CI, 2.85-9.65). After adjusting for patient demographics, comorbidities, and medications, patients with type 2 MI were still more likely to die within 30 days after discharge (RR: 2.89; 95% CI, 1.58-7.46). In addition, patients with type 2 MI were more likely to be readmitted within 30 days after discharge than patients with type 1 NSTEMI (17.7% versus 13.9%, P < 0.01) (RR: 1.27; 95% CI, 1.08-2.5). CONCLUSIONS: Close to one third of patients given the diagnosis of type 1 NSTEMI at discharge at our institution were type 2 MI patients. Patients with type 2 MI are managed differently from type 1 NSTEMI patients and have higher 30-day mortality and readmission rate. Misclassification of type 2 MI as type 1 NSTEMI can have a significant impact on hospitals MI clinical performance and quality measures.

Post-Close Technique for Arteriotomy Hemostasis After Impella Removal.

Utilization of large-bore sheaths has increased dramatically with the advancement of hemodynamic support devices. The pre-close technique is widely used to achieve hemostasis after device removal. However, this technique might fail or be deferred in certain situations, such as planned extended hemodynamic support or emergencies. Perclose employment in arteriotomies larger than 8 Fr might not be successful, as the device foot does not catch the vessel's anterior wall. We describe a simple "postclose" technique for large arteriotomies (13-14 Fr) after removal of Impella 2.5 or CP systems (Abiomed) from the common femoral artery, using two Perclose devices.

Percutaneous transaxillary approach for peripheral endovascular interventions.

OBJECTIVES: To assess the safety and feasibility of percutaneous transaxillary (TAx) access for peripheral endovascular interventions. BACKGROUND: The common femoral artery (CFA) is the most commonly used access site for peripheral endovascular interventions. However, its use might be precluded in multiple circumstances. The axillary artery is comparable in size to the CFA and is less affected by atherosclerosis. Data regarding its percutaneous use in peripheral endovascular interventions are scarce. METHODS: Consecutive patients who underwent percutaneous TAx peripheral endovascular interventions were identified. Demographic and periprocedural data were extracted. Axillary artery access was obtained percutaneously with the arm abducted. A destination sheath was advanced to the relevant vessel. Endovascular interventions were performed using standard devices and techniques. Vascular closure devices were utilized to achieve hemostasis. Primary endpoints included procedural technical success, access-related complications, and major adverse events (MAEs). Secondary endpoints included cannulation time, total procedure time, fluoroscopy time, and length of stay (LOS). RESULTS: Percutaneous TAx access was successfully utilized to perform 41 procedures in 29 patients, lacking a suitable conventional access. Three quarters of target vessels were infrainguinal. The lesions of 61% were classified as TransAtlantic Inter-Society Consensus (TASC) C or D. Access-related complications occurred in two procedures (5%). No MAEs occurred. Median cannulation time was 12 min, procedure time 135 min, fluoroscopy time 20 min, and LOS 1 day. CONCLUSIONS: When no suitable access exists for lower extremity catheter-based interventions, percutaneous TAx approach is a feasible and safe alternative. As such facility with this approach is a valuable asset for interventionalists.
