Few data are available on the safety of interventions for peripheral arterial disease (PAD) performed in the office-based laboratory (OBL) setting. Thus, the aim of this study was to investigate the short- and late-term outcomes of patients treated in OBL vs hospital settings.

We included patients with PAD treated with any United States Food and Drug Administration approved or cleared devices for distal femoropopliteal and/or infrapopliteal disease. Data were retrieved from the LIBERTY 360 study. A propensity-scored, matched analysis was conducted and hazard ratios with the respective 95% confidence intervals were synthesized to examine the outcomes after interventions at OBL vs non-OBL settings.

A total of 710 propensity-scored patients (355 OBL patients and 355 non-OBL patients) with 907 treated lesions (454 OBL lesions and 453 non-OBL lesions), were included. For almost all subjects, balloon angioplasty was the preferred treatment approach (341 [96.1%] in the OBL group vs 353 [99.4%] in the non-OBL gThese results demonstrate that treatment at OBLs is comparable to non-OBL settings. Further comparative studies and larger registries are needed to benchmark procedural quality and long-term outcomes.

Both balloon-expandable and self-expanding transcatheter aortic valves are used for transcatheter aortic valve implantation (TAVI). We compared procedural and clinical outcome variables of Sapien 3 and Evolut R/Pro in an all-comers collective.

In this single-center registry, patients were consecutively treated with the Sapien 3 from November 2014 to March 2017 (n = 129) and from April 2017 to December 2018 mainly (>95%) with the Evolut R/Pro (n = 124), due to a switch in the main TAVI supplier driven by hospital management. Data were retrospectively analyzed before and after the switch.

One-year follow-up data were available for 122 (94%) of the Sapien and 112 (90%) of the Evolut patients. Baseline characteristics were comparable (EuroSCORE Sapien 21.8 ± 0.9% vs Evolut 22.5 ± 0.8%; P=.20). Evolut implantation was associated with a higher radiation dose (Sapien 35770 ± 2345 mGy•cm² vs Evolut 85072 ± 8202 mGy•cm²; P<.001), more postimplantation balloon dilations (Sapien 17.1% vs Evolut 37.1%; P<.001), but similar procedure time (Sapien 75.2 ± 3.8 min vs Evolut 74.6 ± 3 min; P=.30). Metabolism inhibitor In-hospital mortality (Sapien 3.1% vs Evolut 4.0%; P=.70), all-cause mortality (Sapien 13.2% vs Evolut 15.3%; P=.70), all-stroke rate (Sapien 1.5% vs Evolut 6.5%; P=.05), and pacemaker implantation rate (Sapien 13.2% vs Evolut 18.5%; P=.30) were similar at 1 year. Permanent pacemaker rate was numerically higher in the first 6 months with Evolut (<6 months 26.7% vs >6 months 16%; P=.62); furthermore, radiation dose and balloon dilations also suggest a learning curve with Evolut.

Switching from Sapien 3 to Evolut R/Pro was not associated with a difference regarding periprocedural or 1-year clinical outcomes.

Despite increasing use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with cardiogenic shock (CS) secondary to ST-segment elevation myocardial infarction (STEMI), a paucity of adequate evidence for this therapy remains. The aim of this single-center clinical registry study was to identify predictors of survival and discern the possible optimal time to initiate VA-ECMO in this cohort.

Seventy-nine consecutive patients with CS complicating STEMI who received VA-ECMO support were included in this analysis. The primary endpoint was survival at 6 months after initiation of VA-ECMO. Mean age was 60 ± 11 years. Forty-six patients (58%) were successfully weaned from VA-ECMO and 30 patients (38%) could be discharged. Of these, 23 patients (29% of the overall population) survived up to 6-month follow-up. Multivariate analysis to identify determinants of survival showed no association between the time of CS onset to VA-ECMO start time and 6-month survival (P=.75). Glomerular filtration rate on admission (P<.001), white blood cell count on admission (P≤.01), age (P≤.01), and arterial lactate level 1 and 24 hours after VA-ECMO initiation (P=.01) were the strongest predictors of survival.

The timing of VA-ECMO initiation in patients with CS complicating STEMI was not a prognostic factor of survival. Renal function, white blood cell count, age, and lactate level were the strongest predictors of death during 6-month follow-up.

The bulk morphology of such cells plays a key role in charge generation, recombination, and transport, thus determining the device performance. Although numerous studies have discussed the morphology-performance relationship of these cells, the method of designing OPV materials with the desired morphology remains unclear. Herein, guided by molecular electrostatic potential distributions, we have established a connection between the chemical structure and bulk morphology. We show that the molecular orientation at the D-A interface and the domain purity in the blend can be effectively modulated by modifying the functional groups. Enhancing the D-A interaction is beneficial for charge generation. However, the resulting low domain purity and increased charge transfer ratio in its hybridization with the local excitation states lead to severe charge recombination. Fine-tuning the bulk morphology can give balanced charge generation and recombination, which is crucial for further boosting the efficiency of the OPV cells.

Most studies examined spot urine sodium's (sUNa

) prognostic utility during the early phase of acute heart failure (AHF) hospitalization. In AHF, sodium excretion is related to clinical status; therefore, we investigated the differences in the prognostic information of spot UNa

throughout the course of hospitalization for AHF (admission vs. discharge).

The study population were AHF patients (n=172), who survived the index hospitalization. We compared the relationship between early (on admission, at 24 and 48h) and discharge sUNa

measurements with post-discharge study endpoints composite of 1year all-cause mortality and AHF rehospitalization (with time to first event analysis) as well as with each event in separation. There were 49 (28.5%) deaths, 40 (23.3%) AHF rehospitalizations, while the composite endpoint occurred in 69 (40.1%) during 1year follow-up. The sUNa

had prognostic significance for the composite endpoint when assessed on admission, at 24 and at 48h hazard ratios (HRs) with 95% confid discharge sUNa

73±35 vs. 70±35 P=0.82 (mmol/L).

Spot UNa

assessed at early phase of hospitalization and at discharge have different prognostic significance, which confirms that it should be always interpreted along with clinical context.

The MOMENTUM 3 pivotal trial established superiority of the HeartMate 3 (HM3) left ventricular assist device (LVAD), a fully magnetically levitated centrifugal-flow pump, over the HeartMate II axial-flow pump. We now evaluate HM3 LVAD outcomes in a single-arm prospective continuous access protocol (CAP) post-pivotal trial study.

We enrolled 2200 HM3 implanted patients (515 pivotal trial and 1685 CAP patients) and compared outcomes including survival free of disabling stroke or reoperation to replace or remove a malfunctioning device (primary composite endpoint), overall survival and major adverse events at 2 years. The 2-year primary endpoint [76.7% vs. 74.8%; adjusted hazard ratio (HR) 0.87, 95% confidence interval (CI) 0.71-1.08, P=0.21] and overall survival (81.2% vs. 79.0%) were similar among CAP and pivotal cohorts despite sicker patients (more intra-aortic balloon pump use and INTERMACS profile 1) in CAP who were more often intended for destination therapy. Survival was similar between the CAP and pivotal trial in transplant ineligible patients (79.1% vs. 76.7%; adjusted HR 0.89, 95% CI 0.68-1.16, P=0.38). In a pooled analysis, the 2-year primary endpoint was similar between INTERMACS profiles 1-2 ('unstable' advanced heart failure), profile 3 ('stable' on inotropic therapy), and profiles 4-7 ('stable' ambulatory advanced heart failure) (75.7% vs. 77.6% vs. 72.9%, respectively). The net burden of adverse events was lower in CAP (adjusted rate ratio 0.93, 95% CI 0.88-0.98, P=0.006), with consequent decrease in hospitalization.

The primary results of accumulating HM3 LVAD experience suggest a lower adverse event burden and similar survival compared to the pivotal MOMENTUM 3 trial.

There is a paucity of literature on safety and efficacy of various transseptal puncture (TSP) needles.

To assess the reported mechanisms of failure, complications, and outcomes among the most frequently used transseptal needles in the United States.

We queried the Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database between January 2011 and January 2021 for reports on the most commonly used transseptal needles NRG (Baylis Medical, Montreal, Canada), and BRK (St. Jude, Saint Paul, MN)]. The primary outcome was the mechanism of failure. Secondary outcomes included clinical consequences of device failure.

The final analysis included 306 reports of failure/complication with TSP needles (NRG n= 70, BRK n= 236). The most commonly reported mode of failure was detachment of the needle component (i.e., clip, hub, stopcock, shaft, spring, or needle tip) (14.7% overall; 17.8% BRK; and 4.3% NRG). Among these reports, cardiac perforation was the most common complicatP training.Comprehensive gas chromatography with time of flight mass spectrometry is a powerful tool in the analysis of complex samples. Chemometric analysis of raw chromatographic data is more useful in one- and two-dimensional separations relative to peak tables. The data volume from such experiments generally necessitates the use of data reduction tools. Such tools often sacrifice some of the multivariate information in the mass to charge ratio dimension. The unique ion filter reduces the over-redundancy in two-dimensional gas chromatography-mass spectrometry data by limiting the data to a few unique/pseudo-unique ions, sub-peaks/slices in the first dimension, and spectra in the second dimension. We explore the performance of this algorithm through careful inspection of two-dimensional gas chromatography-mass spectrometry data before and after application of the filter. A reduction (99%) in the number of variables in a two-dimensional gas chromatography-mass spectrometry chromatogram passed on to subsequent analysis was observed.
