Percutaneous Axillary Access for Placement of Microaxial Ventricular Support Devices: The Axillary Access Registry to Monitor Safety (ARMS).

ABSTRACT:

Background

There has been increasing utilization of short-term mechanical circulatory support devices for a variety of clinical indications. Many patients have suboptimal iliofemoral access options or reasons why early mobilization is desirable. Axillary artery access is an option for these patients, but little is known about the utility of this approach to facilitate short-term use for circulatory support with microaxial pump devices.

Methods

The Axillary Access Registry to Monitor Safety (ARMS) was a prospective, observational multicenter registry to study the feasibility and acute safety of mechanical circulatory support via percutaneous upper-extremity access.

Results

One hundred and two patients were collected from 10 participating centers. Successful device implantation was 98% (100 of 102). Devices were implanted for a median of 2 days (interquartile range, 0-5 days; range, 0-35 days). Procedural complications included 10 bleeding events and 1 stroke. There were 3 patients with brachial plexus-related symptoms all consisting of C8 tingling and all arising after multiple days of support. Postprocedural access site hematoma or bleeding was noted in 9 patients. Device explantation utilized closure devices alone in 61%, stent grafts in 17%, balloon tamponade facilitated closure in 15%, and planned surgical explant in 5%. Duration of support appeared to be independently associated with a 1.1% increased odds of vascular complication per day ([95% CI, 0.0%-2.3%] P=0.05).

Conclusions

Percutaneous axillary access for use with microaxial support pumps appears feasible with acceptable rates of bleeding despite early experience. Larger studies are necessary to confirm the pilot data presented here.

Project description:BackgroundPercutaneous ventricular assist devices (PVADs) have been replacing intra-aortic balloon pumps for hemodynamic support during percutaneous coronary intervention (PCI), even though data supporting a benefit for hard clinical end points remain limited. We evaluated diffusion of PVADs across US markets and examined the association of market utilization of PVAD with mortality and cost.MethodsUsing the 2013 to 2019 Medicare data, we identified all patients aged ≥65 years who underwent PCI with either a PVAD or intra-aortic balloon pump. We used hospital referral region to define regional health care markets and categorized them in quartiles based on the proportional use of PVADs during PCI. Multilevel models were constructed to determine the association of patient, hospital, and market factors with utilization of PVADs and the association of PVAD utilization with 30-day mortality and cost.ResultsA total of 79 176 patients underwent PCI with either intra-aortic balloon pump (47 514 [60.0%]) or PVAD (31 662 [40.0%]). The proportion of PCI procedures with PVAD increased over time (17% in 2013 to 57% in 2019; P for trend, <0.001), such that PVADs overtook intra-aortic balloon pump for hemodynamic support during PCI in 2018. There was a large variation in PVAD utilization across markets (range, 0%-85%), which remained unchanged after adjustment of patient characteristics (median odds ratio, 2.05 [95% CI, 1.91-2.17]). The presence of acute myocardial infarction, cardiogenic shock, and emergent status was associated with a 45% to 50% lower odds of PVAD use suggesting that PVADs were less likely to be used in the sickest patients. Greater utilization of PVAD at the market level was not associated with lower risk mortality but was associated with higher cost.ConclusionsAlthough utilization of PVADs for PCI continues to increase, there is large variation in PVAD utilization across markets. Greater market utilization of PVADs was not associated with lower mortality but was associated with higher cost.

Project description:BackgroundRecent studies describe an emerging role for percutaneous left ventricular assist devices such as Impella CP® as rescue therapy for refractory cardiac arrest. We hypothesized that the addition of mechanical chest compressions to percutaneous left ventricular assist device assisted CPR would improve hemodynamics by compressing the right ventricle and augmenting pulmonary blood flow and left ventricular filling. We performed a pilot study to test this hypothesis using a swine model of prolonged cardiac arrest.MethodsEight Yorkshire swine were anesthetized, intubated, and instrumented for hemodynamic monitoring. They were subjected to untreated ventricular fibrillation for 5.75 (SD 2.90) minutes followed by mechanical chest compressions for a mean of 20.0 (SD 5.0) minutes before initiation of percutaneous left ventricular assist device. After percutaneous left ventricular assist device initiation, mechanical chest compressions was stopped (n = 4) or continued (n = 4). Defibrillation was attempted 4, 8 and 12 minutes after initiating percutaneous left ventricular assist device circulatory support.ResultsThe percutaneous left ventricular assist device + mechanical chest compressions group had significantly higher percutaneous left ventricular assist device flow prior to return of spontaneous heartbeat at four- and twelve-minutes after percutaneous left ventricular assist device initiation, and significantly higher end tidal CO2 at 4-minutes after percutaneous left ventricular assist device initiation, when compared with the percutaneous left ventricular assist device alone group. Carotid artery flow was not significantly different between the two groups.ConclusionThe addition of mechanical chest compressions to percutaneous left ventricular assist device support during cardiac arrest may generate higher percutaneous left ventricular assist device and carotid artery flow prior to return of spontaneous heartbeat compared to percutaneous left ventricular assist device alone. Further studies are needed to determine if this approach improves other hemodynamic parameters or outcomes after prolonged cardiac arrest.
