A novel approach to saline/contrast delivery in excimer laser coronary atherectomy (ELCA) to enhance efficacy: MAXCon ELCA technique.

The advent of excimer laser coronary atherectomy (ELCA) nearly four decades ago heralded a novel way to treat complex lesions, both coronary and peripheral, which were previously untraversable and thus untreatable. These complex lesions include heavily calcified lesions, ostial lesions, bifurcation lesions, chronic total occlusions, in-stent restenosis (including stent underexpansion), and degenerative saphenous vein grafts. We discuss the technology of ELCA, its indications, applications, and complications, and suggest the "MAXCon ELCA" technique for better outcomes without increased risk. Lastly, we present a case of MAXCon ELCA effectively treating a complex lesion.

Incidental Finding of Secondary Tumoral Calcinosis Following Cardiothoracic Surgery: The Role of Multimodality Imaging Including Spectral Detector Computed Tomography.

Tumoral calcinosis is a rare syndrome that affects mostly soft tissues. It is characterized by calcium salt deposition in the periarticular soft tissue surrounding bony structures forming slow-growing, seldom asymptomatic masses. This case report describes a 41-year-old male with end-stage renal disease on home hemodialysis, who presented with an unusual rapidly progressive mass overlying the manubrium and suprasternal notch, following recent cardiothoracic surgery, which was initially felt to be a hematoma. The case highlights the role of spectral detector computed tomography (SDCT) in reaching the correct diagnosis of tumoral calcinosis as well as demonstrating additional changes of ectopic parathyroid hyperplasia in the anterior mediastinum.

Supplemental calcium and vitamin D and long-term mortality in aortic stenosis.

OBJECTIVE: Calcium metabolism has long been implicated in aortic stenosis (AS). Studies assessing the long-term safety of oral calcium and/or vitamin D in AS are scarce yet imperative given the rising use among an elderly population prone to deficiency. We sought to identify the associations between supplemental calcium and vitamin D with mortality and progression of AS. METHODS: In this retrospective longitudinal study, patients aged ≥60 years with mild-moderate native AS were selected from the Cleveland Clinic Echocardiography Database from 2008 to 2016 and followed until 2018. Groups were stratified into no supplementation, supplementation with vitamin D alone and supplementation with calcium±vitamin D. The primary outcomes were mortality (all-cause, cardiovascular (CV) and non-CV) and aortic valve replacement (AVR), and the secondary outcome was AS progression by aortic valve area and peak/mean gradients. RESULTS: Of 2657 patients (mean age 74 years, 42% women) followed over a median duration of 69 months, 1292 (49%) did not supplement, 332 (12%) took vitamin D alone and 1033 (39%) supplemented with calcium±vitamin D. Calcium±vitamin D supplementation was associated with a significantly higher risk of all-cause mortality (absolute rate (AR)=43.0/1000 person-years; HR=1.31, 95% CI (1.07 to 1.62); p=0.009), CV mortality (AR=13.7/1000 person-years; HR=2.0, 95% CI (1.31 to 3.07); p=0.001) and AVR (AR=88.2/1000 person-years; HR=1.48, 95% CI (1.24 to 1.78); p<0.001). Any supplementation was not associated with longitudinal change in AS parameters in a linear mixed-effects model. CONCLUSIONS: Supplemental calcium with or without vitamin D is associated with lower survival and greater AVR in elderly patients with mild-moderate AS.

Triglycerides: How to Manage Patients with Elevated Triglycerides and When to Refer?

Hypertriglyceridemia (HTG) is among the most common dyslipidemias seen in clinical practice. Studies in recent years have demonstrated a causal relationship between triglyceride-rich lipoproteins (TRL) and cardiovascular disease (CVD). This is primarily due to enhanced atherogenicity of cholesterol-enriched remnants, the metabolic byproducts of TRLs. Other factors influencing atherogenicity of TRLs include apolipoprotein CIII-directed proinflammatory signaling pathways and triglyceride enrichment of low-density lipoprotein that results in overabundance of small dense atherogenic particles within a prooxidative milieu that serves as the gateway for unregulated incorporation by vascular wall macrophages. HTG is caused by familial and metabolic disorders as well as selected medications that impair TRL hydrolysis.

Incidence, Predictors, and Implications of Permanent Pacemaker Requirement After Transcatheter Aortic Valve Replacement.

Transcatheter aortic valve replacement (TAVR) is a safe and feasible alternative to surgery in patients with symptomatic severe aortic stenosis regardless of the surgical risk. Conduction abnormalities requiring permanent pacemaker (PPM) implantation remain a common finding after TAVR due to the close proximity of the atrioventricular conduction system to the aortic root. High-grade atrioventricular block and new onset left bundle branch block (LBBB) are the most commonly reported conduction abnormalities after TAVR. The overall rate of PPM implantation after TAVR varies and is related to pre-procedural and intraprocedural factors. The available literature regarding the impact of conduction abnormalities and PPM requirement on morbidity and mortality is still conflicting. Pre-procedural conduction abnormalities such as right bundle branch block and LBBB have been linked with increased PPM implantation and mortality after TAVR. When screening patients for TAVR, heart teams should be aware of various anatomical and pathophysiological conditions that make patients more susceptible to increased risk of conduction abnormalities and PPM requirement after the procedure. This is particularly important as TAVR has been recently approved for patients with low surgical risk. The purpose of this review is to discuss the incidence, predictors, impact, and management of the various conduction abnormalities requiring PPM implantation in patients undergoing TAVR.

Impact of exposure to patients with COVID-19 on residents and fellows: an international survey of 1420 trainees.

OBJECTIVES: To determine how self-reported level of exposure to patients with novel coronavirus 2019 (COVID-19) affected the perceived safety, training and well-being of residents and fellows. METHODS: We administered an anonymous, voluntary, web-based survey to a convenience sample of trainees worldwide. The survey was distributed by email and social media posts from April 20th to May 11th, 2020. Respondents were asked to estimate the number of patients with COVID-19 they cared for in March and April 2020 (0, 1-30, 31-60, >60). Survey questions addressed (1) safety and access to personal protective equipment (PPE), (2) training and professional development and (3) well-being and burnout. RESULTS: Surveys were completed by 1420 trainees (73% residents, 27% fellows), most commonly from the USA (n=670), China (n=150), Saudi Arabia (n=76) and Taiwan (n=75). Trainees who cared for a greater number of patients with COVID-19 were more likely to report limited access to PPE and COVID-19 testing and more likely to test positive for COVID-19. Compared with trainees who did not take care of patients with COVID-19 , those who took care of 1-30 patients (adjusted OR [AOR] 1.80, 95% CI 1.29 to 2.51), 31-60 patients (AOR 3.30, 95% CI 1.86 to 5.88) and >60 patients (AOR 4.03, 95% CI 2.12 to 7.63) were increasingly more likely to report burnout. Trainees were very concerned about the negative effects on training opportunities and professional development irrespective of the number of patients with COVID-19 they cared for. CONCLUSION: Exposure to patients with COVID-19 is significantly associated with higher burnout rates in physician trainees.

Oral Calcium Supplements Associate With Serial Coronary Calcification: Insights From Intravascular Ultrasound.

OBJECTIVES: This study sought to evaluate and assess the extent of serial coronary artery calcification in response to oral calcium supplementation. BACKGROUND: Oral calcium supplements are frequently used despite their cardiovascular safety remaining controversial. Their effects on serial coronary calcification are not well established. METHODS: In a post hoc patient-level analysis of 9 prospective randomized trials using serial coronary intravascular ultrasound, changes in serial percentage of atheroma volume (PAV) and calcium indices (CaI) were compared in matched segments of patients coronary artery disease who were receiving concomitant calcium supplements (n = 447) and in those who did not receive supplements (n = 4,700) during an 18- to 24-month trial period. RESULTS: Patients (mean age 58 ± 9 years; 73% were men; 43% received concomitant high-intensity statins) demonstrated overall annualized changes in PAV and CaI with a mean of -0.02 ± 1.9% (p = 0.44) and a median of 0.02 (interquartile range: 0.00 to 0.06) (p < 0.001) from baseline, respectively. Following propensity-weighted mixed modeling adjusting for treatment and a range of demographic, clinical, ultrasonic, and laboratory parameters (including but not limited to sex, race, baseline, and annualized change in PAV, baseline CaI, concomitant high-intensity statins, diabetes mellitus, renal function), there were no significant between-group differences in annualized changes in PAV (least-squares mean: 0.09; 95% confidence interval [CI]: -0.20 to 0.37 vs. 0.01; 95% CI: -0.27 to 0.29; p = 0.092) according to calcium supplement intake. Per a multivariable logistic regression model accounting for the range of covariates described, calcium supplementation independently associated with an increase in annualized CaI (odds ratio: 1.15; 95% CI: 1.05 to 1.26; p = 0.004). CONCLUSIONS: Oral calcium supplementation may increase calcium deposition in the coronary vasculature independent of changes in atheroma volume. The impact of these changes on plaque stability and cardiovascular outcomes requires further investigation.

Impact of atrial fibrillation on outcomes following MitraClip: A contemporary population-based analysis.

OBJECTIVES: Despite the rising use of MC, the impact of preexisting AF, a common comorbidity, on short-term postprocedural outcomes is poorly defined. We sought to assess outcomes between patients with and without atrial fibrillation (AF) who underwent percutaneous mitral valve repair with MitraClip (MC). METHODS: In this retrospective cohort study, the Nationwide Readmissions Database was queried for patients who underwent MC between 2014-2017. Groups were stratified based on the presence of AF. Multivariable logistic regression analyses were performed to identify the association between AF and in-hospital stroke and mortality. RESULTS: Of the 15,570 patients who underwent MC, 7,740 (49.7%) had AF. AF patients were older (82 vs. 79 years, p < .001) and more comorbid. Patients with AF relative to without AF demonstrated increased rates of in-hospital ischemic (1.3% vs .0.7%, p < .001) and hemorrhagic stroke (0.3% vs. 0.1%, p = .007), longer duration of hospitalization (median 3 vs. 2 days, p < .001), and similar in-hospital mortality (2.8% vs. 2.6%, p = .52). After adjusting for comorbidities, age, sex, hospital procedural volume, and CHA2DS2-VASc, the presence of AF was associated with higher in-hospital stroke (OR = 2.096, 95%CI[1.503-2.921], p < .001) but not in-hospital mortality (OR = 1.012, 95%CI[0.828-1.238], p = .904). AF patients were more likely to be readmitted (16.8% vs.14.1%, p < .001) and die (1.5% vs. 0.9%, p = .005) within 30 days of discharge despite similar incidences of stroke (0.7% vs. 0.6%, p = .53). CONCLUSIONS: The increased risk of in-hospital stroke, 30-day mortality, and longer hospitalization suggest the need for increased preprocedural optimization by means of stroke prevention strategies in those with AF undergoing MC.

Icosapent Ethyl: Niche Drug or for the Masses?

PURPOSE OF REVIEW: Despite achieving optimal levels of low-density lipoprotein cholesterol (LDL-C) with statins, the risk of atherosclerotic cardiovascular disease (ASCVD) persists. The purpose of this review is to outline the effects of icosapent ethyl (IPE), an ultra-purified eicosapentaenoic acid (EPA) on ASCVD risk assessment. RECENT FINDINGS: Many studies have shown that elevated triglycerides (TG) contribute to increased risk of ASCVD. However, the only outcomes trial to date to demonstrate a benefit in patients with elevated TG beyond its lipid-lowering properties is REDUCE-IT. Yet, despite IPE demonstrating a relatively modest reduction in TG (~ 20%), there was a 25% relative risk reduction in the primary endpoint and a 30% reduction in total events. Sub-analysis of REDUCE-IT also showed a statically significant decrease in cardiac arrest (HR 0.52 (0.31-0.86), p = 0.01) and sudden cardiac death (HR 0.69 (0.50-0.96), p = 0.03). The CVD benefits observed in REDUCE-IT coincide with on-treatment EPA levels. Icosapent ethyl's multiple bioactive properties contribute to CVD risk reduction beyond TG lowering effects. Because patients with a REDUCE-IT-like profile are highly prevalent in the USA and abroad, IPE should not be viewed as a niche drug, but rather part of a proven armamentarium that deserves widespread use in appropriate patients at elevated ASCVD risk.

Comparison of Outcomes of Transcatheter Mitral Valve Repair (MitraClip) in Patients <80 Years Versus ≥80 Years.

The influence of age on outcomes of patients selected for transcatheter mitral valve repair (TMVR) remains largely unknown in the United States. This study sought to assess the outcomes of TMVR in highly aged patients (≥80 years). We queried the National Readmission Database from January 2014 to December 2016 for elective TMVR hospitalizations. Propensity-score matching was used to compare in-hospital and 30-day outcomes between highly aged patients and those less than 80 years. Of 6,025 (weighted national estimate) hospitalizations for TMVR, total of 3,368 included highly aged patients (mean age 85.3) and 2,657 included patients less than 80 years (mean age 69). In the Propensity-score matched cohort (age≥ 80, n = 2,185; age <80, n = 2,197), highly aged patients had similar rates of in-hospital mortality (2.2% vs 1.6%; p = 0.22), ischemic stroke (0.5% vs 0.5%; p = 0.83), cardiac tamponade (0.2% vs 0.4%; p = 0.58), cardiogenic shock (1.2% vs 1.7%; p = 0.25), and acute myocardial infarction (0.6% vs 0.4%; p = 0.30), but higher rates of discharge to skilled nursing facility(9.7% vs 4.5%; p <0.001), all-cause 30-day readmissions (14.2% vs 10.5%; p <0.001), and heart failure-related 30-day readmissions (4.7% vs 3.0%; p = 0.006), compared with those less than 80 years. TMVR therapy is safe and is associated with low rates of in-hospital adverse events but higher rate of 30-day readmissions in highly aged patients compared with patients less than 80 years. Evidence-based interventions proven to be effective in reducing the burden of heart failure readmissions should be utilized in these patients to further improve outcomes.

Comparison of acute recoil after valve deployment and after post-dilation in patients undergoing transfemoral-transcatheter aortic valve replacement with SAPIEN-3 valve.

BACKGROUND: Transcatheter aortic valves are prone to acute recoil similar to the metal-based coronary stents. However, it is not clear if recoil remains a factor only after the initial valve deployment or also after post-dilation. METHODS: We conducted a retrospective observational study of patients who underwent transfemoral transcatheter aortic valve replacement (TAVR) with SAPIEN-3 valve. Acute recoil at the upper, central, and lower levels of the valve was calculated in both anteroposterior right anterior oblique (RAO) and lateral left anterior oblique (LAO) views after initial deployment as well as after post-dilation. The average recoil of the RAO and LAO views was also calculated and described as RAO/LAO. RESULTS: The acute recoil in the RAO/LAO views (mean ± SD) was 3.9 ± 1.1% after valve deployment in the whole study population (n = 257). Among the subset of patients who required post-dilation (n = 133), the mean acute recoil in the RAO/LAO views was found to be greater after initial valve deployment as compared with after post-dilation (3.8 ± 1.1% vs. 3.0 ± 0.9%; p < .001). Further, acute recoil was significantly greater in the RAO view than the LAO view and at the central level of the prosthesis as compared with the upper and lower levels. Those findings were consistent after initial deployment as well as after post-dilation. Clinical outcomes were similar between patients who required post-dilation compared to those who did not. In multivariable logistic regression analysis, only smaller valve cover index was found to be an independent predictor of 30-day mild or greater aortic regurgitation (OR 0.007; 95% CI 0.0001-0.707; p = .035). CONCLUSION: Acute elastic recoil of the SAPIEN-3 valve was significantly less after post-dilation as compared with after deployment. It was also greater when measured in the RAO view as compared with the LAO view. Furthermore, acute recoil was not homogenous across the height of the valve stent frame.

Incidence, Clinical Presentation, and Causes of 30-Day Readmission Following Hospitalization With Spontaneous Coronary Artery Dissection.

OBJECTIVES: The aim of this study was to investigate the impact of spontaneous coronary artery dissection (SCAD) on 30-day readmission rates following hospitalization with acute myocardial infarction (AMI) using a national database. BACKGROUND: AMI in the setting of SCAD represents an uncommon type of myocardial infarction with limited data on short-term outcomes. METHODS: All hospitalizations with primary or index diagnoses of AMI from 2010 to 2015 in the Nationwide Readmissions Database were queried. The primary outcome was overall 30-day readmission rates in both SCAD and non-SCAD cohorts. Propensity score matching (1:2) was conducted. RESULTS: A total of 2,654,087 patients with AMI were included in the final analysis, of whom 1,386 (0.052%) were diagnosed with SCAD. SCAD was associated with a higher readmission rate in the SCAD cohort (12.3% vs. 9.9%; p = 0.022). The main causes of readmissions in the SCAD cohort were cardiac causes (80.6%), and AMI was the most common cardiac cause (44.8%), followed by chest pain (20.1%) and arrhythmia (12.7%). Among the SCAD readmissions, 50.6% patients were readmitted in the first week post-discharge, with 54.5% of AMI readmissions occurring in the first 2 days post-discharge. CONCLUSIONS: The incidence of 30-day readmission following AMI and SCAD is nontrivial and occurs early post-discharge. Most readmissions are due to cardiac causes, especially AMI. Targeted management approaches are needed to diminish the high rates of readmission and early recurrent AMI.

The Utility of Rapid Atrial Pacing Immediately Post-TAVR to Predict the Need for Pacemaker Implantation.

OBJECTIVES: The aim of this study was to determine the utility of rapid atrial pacing immediately after transcatheter aortic valve replacement (TAVR) to predict the need for permanent pacemaker implantation (PPI). BACKGROUND: Risk stratification for patients without high-grade atrioventricular block (AVB) after TAVR is imprecise and based on anatomic considerations, electrocardiographic characteristics, and clinical suspicion. A more reliable assessment is necessary to minimize inpatient rhythm monitoring and/or reduce unnecessary PPI. METHODS: Consecutive patients undergoing TAVR at 2 centers were included. After valve implantation in patients without pacemakers who did not have complete heart block or atrial fibrillation, the temporary pacemaker was withdrawn from the right ventricle and placed in the right atrium. Rapid atrial pacing was performed from 70 to 120 beats/min, and patients were assessed for the development of Wenckebach AVB. Patients were then followed for clinical outcomes, including PPI. RESULTS: A total of 284 patients were included. Of these, 130 (45.8%) developed Wenckebach AVB. There was a higher rate of PPI within 30 days of TAVR among the patients who developed Wenckebach AVB (13.1% vs. 1.3%; p < 0.001), with a negative predictive value for PPI in the group without Wenckebach AVB of 98.7%. A greater percentage of patients receiving self-expanding valves required PPI than those receiving a balloon-expandable valves (15.9% vs. 3.7%; p = 0.001), though these rates were still relatively low among patients who did not develop Wenckebach AVB (2.9% and 0.8%). CONCLUSIONS: Atrial pacing post-TAVR is easily performed and can help identify patients who may benefit from extended rhythm monitoring. Patients who did not develop pacing-induced Wenckebach AVB demonstrated an extremely low likelihood of PPI.

Icosapent ethyl: drug profile and evidence of reduced residual cardiovascular risk in patients with statin-managed LDL-C cholesterol.

INTRODUCTION: Icosapent ethyl (IPE) is a highly purified (>96%) form of eicosapentanoic acid, a marine-derived omega-3 fatty acid known to reduce serum triglyceride (TG) levels. In the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT), the addition of 4 g IPE daily resulted in a 25% reduction in cardiovascular events beyond statins and other standard of care therapies. IPE is now the only therapy currently approved by the Food and Drug Administration to treat patients with elevated TGs (150-499 mg/dL) with cardiovascular disease (CVD) or Type 2 diabetes mellitus and two or more CVD risk factors.Areas covered: IPE is a highly purified form of eicosapentanoic acid for patients with elevated TGs as monotherapy or combined with statins and/or other lipid lowering therapies.The REDUCE-IT Study demonstrated a 25% reduction in the primary outcome measure and 30% reduction in total CVD events in high-risk patients with elevated TGs (135-499 mg/dL) assigned to IPE (4 g daily).Side effects included a statistically significant increased risk of atrial fibrillation and bleeding, although the risk of stroke was reduced and there were no cases of fatal bleeding.The FDA recently approved IPE for treatment of patients with TG levels of 150-499 mg/dL and preexisting CVD or Type 2 diabetes mellitus with two or more risk factors.Expert opinion:IPE has proven to be superior to other forms of omega 3 fatty acid in reducing CVD risk in patients with elevated TG. This could be attributed to multiple factors including the use of highly purified eicosapentaenoic acid ethyl esters without docosahexaenoic acid (DHA), thus preventing the increase in low-density lipoprotein cholesterol associated with DHA especially at high TG levels, reduction in atherogenic TG-rich particles, antioxidant and anti-inflammatory properties, improvement in endothelial function, and stabilization of atherosclerotic plaque.

Suspicious Right Heart Mass: A Rare Case of Benign Metastasizing Leiomyoma of the Tricuspid Valve.

Benign metastasizing leiomyoma is a rare condition usually affecting women of reproductive age with a history of uterine leiomyoma and characterized by soft tissue masses in various extrauterine sites. We report a case of a 46-year-old woman with previously resected uterine leiomyoma with subsequent pulmonary and tricuspid valve lesions. (Level of Difficulty: Intermediate.).

The utilization of single versus double Perclose devices for transfemoral aortic valve replacement access site closure: Insights from Cleveland Clinic Aortic Valve Center.

INTRODUCTION: Percutaneous femoral access is the preferred access route for transcatheter aortic valve replacement (TAVR). The majority of experienced TAVR centers use two 6F Perclose ProGlide™ devices to close the primary vascular access site, deployed prior to upsizing sheath size with closure completed at the end of the case (the "preclose" approach). A strategy of utilizing a single Perclose device to preclose may have advantages including fewer complications, complexity, and cost, but the safety of this is unknown. This study examines in the safety and efficacy of using a single Perclose versus double Perclose for perclosure of large bore access during TAVR. METHODS: Patients undergoing Transfemoral (TF) TAVR from January 2014 to December 2017 within the Cleveland Clinic Aortic Valve Center were identified. A retrospective review of medical charts was conducted. Vascular complications were defined according to the VARC-2 criteria. RESULTS: A total of 740 patients were included; 487 (65.8%) received a single Perclose device while 253 (34.2%) received double Perclose devices. Baseline characteristics were similar with no differences between the single versus double Perclose groups, respectively. The access sheath size was similar in both groups with (14, 16, and 18 F) being the most common sizes utilized. Of the total 487 patients with single Perclose, 75.6% needed additional closure device (AngioSeal). With double Perclose strategy, additional closure device (AngioSeal) was used in 40.3% patients with 470 (63.5%) patients being successfully perclosed. Vascular complication rates including hematoma, stenosis requiring stenting, pseudoaneurysm, and other major vascular complications were similar between both groups. CONCLUSION: Single 6F ProGlide use for preclosure is a safe strategy for TF TAVR using the S3 valve. Additional closure device was not needed in almost one-quarter of the patients. When necessary, residual bleeding can be controlled with the AngioSeal Device at the end of the procedure. This single device preclose strategy can help to reduce the cost of TAVR procedure without increasing risk.

Unilateral Access Is Safe and Facilitates Peripheral Bailout During Transfemoral-Approach Transcatheter Aortic Valve Replacement.

OBJECTIVES: The aim of this study was to compare the rate and trend of vascular complications when placing a second arterial sheath in the contralateral femoral artery during transcatheter aortic valve replacement (TAVR) unilaterally versus bilaterally. BACKGROUND: Vascular complications occur in approximately 5% to 8% of TAVR procedures. Many operators place a second arterial sheath in the contralateral femoral artery to perform aortic root angiography. The authors surmised that placing the second sheath ipsilateral and distal to the delivery sheath would be an easier option with similar safety. METHODS: The Cleveland Clinic Aortic Valve Center TAVR database was accessed, and data for patients undergoing transfemoral TAVR (TF-TAVR) from January 2014 to December 2017 were analyzed retrospectively. The primary outcome was the rate of peripheral vascular complications. RESULTS: A total of 1,208 patients who underwent TF-TAVR were included in this study. One thousand seven patients (83.36%) underwent bilateral femoral access, and 201 patients (16.64%) underwent TF-TAVR using a unilateral femoral approach. Over the study duration, use of the unilateral access approach trended upward significantly, reaching 43.7% of total cases in 2017. A gradual decline in access site-related vascular complications was observed, from 13.7% in 2014 to 7.4% in 2017. After propensity-score matching, peripheral vascular complications were similar between bilateral access and unilateral access (10.8% vs. 8.6%) (p = 0.543). CONCLUSIONS: There was a significant decline in vascular complications from 2014 to 2017. Unilateral-access TF-TAVR provided similar safety compared with bilateral-access TF-TAVR and is a more accessible approach for managing access site-related complications and possibly achieving better patient satisfaction.
