Veno-venous extracorporeal membrane oxygenation support of pulmonary insufficiency using Avalon Elite ® cannula in pediatric patients
AbstractThe “Avalon Elite®” cannula is a double-lumen cannula used to establish veno-venous extracorporeal membrane oxygenation support. The reported advantages are that extracorporeal circulation can be established by cannulating through the right internal jugular vein only, and there is less re-circulation than with a tw o-cannula technique. It is available in a wide range of cannula sizes and can be used in a variety of patients, from children to adults. We herein report three pediatric cases in which an Avalon Elite® cannula was useful. The first was a case of acute mitral regurgitation due to idiopathic chordal ...

Extracorporeal liver support techniques: a comparison
In conclusion, as extracorporeal purification in liver failure could be considered useful for therapeutic purposes, Cytosorb, being more performing than other systems considered, could represent the device of first choice. (Source: Journal of Artificial Organs)

Mid-term outcomes and hemodynamic performance of the St Jude Medical Epic aortic bioprosthesis for severe aortic stenosis
AbstractThe St. Jude Medical Epic Supra valve is a porcine bioprosthesis designed for complete supraannular implantation. No report has shown the hemodynamic performance and clinical outcomes of aortic valve replacement with the Epic Supra valve for severe aortic stenosis in a Japanese cohort. We retrospectively evaluated 65 patients who underwent aortic valve replacement using the Epic Supra valve for aortic stenosis at our department between May, 2011 and October, 2016. The mean follow-up period was 68.7 ± 32.7 months, and the follow-up rate was 89.2%. The mean age was 76.8 ± 5.3 years. The 1-, 5-, and 8-yea...

Optimizing vancomycin release from novel carbon fiber-reinforced polymer implants with small holes: periprosthetic joint infection treatment
AbstractPeriprosthetic joint infection (PJI) is a catastrophic complication after total hip arthroplasty. A new drug-loaded carbon fiber-reinforced polymer (CFRP) prosthesis with a sustained drug-release mechanism is being developed for one-stage surgery. We aimed to examine the diffusion dynamics of vancomycin from vancomycin paste-loaded CFRP implants. The differences in the in vitro diffusion dynamics of vancomycin paste were investigated using the elution test by varying parameters. These included the mixing ratio of vancomycin and distilled water (1:0.8, 1:1.2, and 1:1.4) for vancomycin paste, and hole diameter (1 m...

Prediction of postoperative atrial fibrillation with the systemic immune-inflammation index in patients undergoing cardiac surgery using cardiopulmonary bypass: a retrospective, single-center study
AbstractThe systemic immune-inflammation index (SII, platelet count × neutrophil–lymphocyte ratio) is a novel parameter for systemic inflammation. Cardiopulmonary bypass (CPB) is associated with systemic inflammatory responses. This retrospective study aimed to determine whether SII could predict postoperative atrial fibrillation (POAF) after cardiac surgery using CPB. Patients who underwent cardiac surgery using CPB between January 2020 and July 2021 were included. The primary outcome was POAF incidence within 7 days. Receiver-operating characteristic (ROC) curve analysis was used to evaluate SII ability in predi...

Noninvasive blood pressure measurement in patients with continuous-flow left ventricular assist devices
AbstractOscillatory blood pressure (OBP) with a slow cuff-deflation system has been proposed as noninvasive measurement of mean arterial pressure (MAP) in patients with continuous-flow left ventricular assist devices (LVADs). However, the challenge is that the measurement is not obtainable in certain patients. We hypothesized that the combined use of color Doppler imaging during OBP measurement (CDBP) could derive MAP accurately. We conducted a prospective observational study in critically ill patients (30 patients with continuous-flow LVADs and 30 control patients without LVADs). Triplicate OBP and CDBP measurements were ...

Relationship between laparoscopic and microscopic findings of peritoneum in peritoneal dialysis patients
We examined macroscopic morphological findings in both parietal and visceral peritoneums and bowel movement and assessed the score semiquantitatively. SMC thickness and vascular patency were examined as microscopic findings. Total laparoscopic finding ’s score (LFS) and microscopic findings, SMC thickness and vascular patency, were associated with PD duration. Total LFS was related to SMC thickness in both visceral and parietal peritoneum, whereas it was related to vascular patency in parietal but not in visceral peritoneum. There was no relati onship between microscopic findings and peritoneal surface color, properties,...

A unique cuff-sewing method to implant heartmate3 LVAD for arrhythmogenic right ventricular cardiomyopathy, facilitated by 3D-printing heart model
AbstractImplantation of left ventricular assist device (LVAD) for arrhythmogenic right ventricular (RV) cardiomyopathy is challenging associated with small LV cavity, laterally dislocated LV apex, thin and fragile RV free wall. A 43-year-old male with more than 10 years of medical treatment developed congestive heart failure related to biventricular failure. Durable LVAD was indicated to prevent further deterioration of the RV function, which would be exacerbated by progression of LV dysfunction. To simulate surgery, we printed-out a 3D heart model based on enhanced CT scanning study to identify the optimal coring positi...

Simultaneous minimally invasive LVAD implantation and extracorporeal RVAD placement by patient with pectus excavatum and biventricular acute heart failure
We describe a novel sternotomy-sparing approach for minimal-invasive biventricular assist device (BiVAD) implantation in a patient with an acute heart failure (HF) due to dilated cardiomyopathy and severe PEx. Moreover, alternative approaches for ventricular assist device (VAD) implantation and timing of the repair of PEx will be discussed. (Source: Journal of Artificial Organs)
