Patient-tailored silicone plug for HeartMate 3 ™ left ventricular assist device explantation
AbstractPatient-tailored silicone plug for HeartMate 3 ™ left ventricular assist device explantation in two successive males proceeded successfully. Given medical therapeutic advancements, FDA-approved plug systems designed by LVAD manufacturers themselves will be necessary for the near future to provide a safe and simple device explantation alternati ve that fulfills all regulatory standards.

Long-term valve performance of St Jude Medical Epic porcine bioprosthesis in aortic position
AbstractThe aim of this study was to review long-term clinical outcomes and valve performance after Epic Supra valve implantation in aortic position. From 2011 to 2022, 44 patients (mean age 75 ± 8 years) underwent surgical aortic valve replacement (SAVR) with an Epic Supra valve at our hospital. Survival, incidence of late complications, and echocardiographic date were retrospectively analyzed. During a mean follow-up period of 6.2 ± 3.5 years, the overall survival rate was 9 1 ± 4% at 2 and 88 ± 5% at 5 years, while rates of freedom from major adverse cardiovascular and cerebrovascular events (MAC...

Monocyte to HDL ratio may predict thrombosis in patients with mechanical mitral and aortic valve prosthesis
This study aimed to find out the potential predictive value of MHR and CAR for PHVT. Patients who had the diagnosis of mechanical mitral/aortic PHVT and normally functioning prosthesis were retrospectively analyzed. Laboratory data including complete blood count and biochemistry were recorded. Transesophageal echocardiography was performed to diagnose PHVT. The study included 118 patients with mechanical PHVT and 120 patients with normally functioning prosthesis. White blood count, monocyte levels, C-reactive protein, MHR and CAR were significantly higher whereas the lymphocyte, HDL and INR levels on admission were lower i...

Evaluation of the reproducibility of preoperative three-dimensional computed tomography planning for posterolateral approach total hip arthroplasty
AbstractThe anteversion of the stem is occasionally intentionally changed by the surgeon for patients with smaller femoral neck anteversion during total hip arthroplasty (THA). However, the reproducibility of preoperative planning with increasing anteversion has been rarely assessed. The present study investigated it using two types of stems. This retrospective study included patients who underwent primary posterolateral THA using taper-wedge (TS group; 73 hips) and anatomical (AS group; 70 hips) stems. Characteristics of sex and age were matched in the two groups by propensity score matching. In both groups, the relations...

A disposable edoxaban sensor chip using carbon paste electrode grafted with molecularly imprinted polymer
In this study, an attempt was made to develop a disposable sensor chip for the rapid detection of edoxaban in blood, a type of DOAC. Molecularly imprinted polymers with edoxaban tosilate as a template and sodiump-styrene sulfonate as a functional monomer were grafted onto the surface of graphite particles, mixed with silicon oil dissolved in ferrocene to form a paste, and filled onto a substrate made of plastic film. Sensor chips were fabricated. The current obtained from this sensor by voltammetry within 150 s depended on the edoxaban concentration. Sensitivity to edoxaban was also confirmed in bovine whole blood. The p...

Comparison of the pre-dilution and post-dilution methods for online hemodiafiltration
In this study, we compared the clinical symptoms, laboratory data, spent dialysate, and adverse events of pre- and post-dilution OL-HDF. We conducted a prospective study of 20 patients who underwent OL-HDF between January 1, 2019 and October 30, 2019. Their clinical symptoms and dialysis efficacy were evaluated. All patients underwent OL-HDF every 3 months in the following sequence: first pre-dilution, post-dilution, and second pre-dilution. We evaluated 18 patients for the clinical study and 6 for the spent dialysate study. No significant differences in spent dialysates regarding small and large solutes, blood pressure,...

Left ventricular remodeling and long-term outcomes of aortic stenosis patients receiving 19 mm Mosaic
AbstractMosaic valve shows higher pressure gradient after aortic valve replacement compared to other same size labeled prostheses in postoperative echocardiogram. The purpose of this study was to evaluate the mid-term echocardiogram findings and long-term clinical outcomes of patients receiving a 19 mm Mosaic. Forty-six aortic stenosis patients receiving 19 mm Mosaic and 112 patients receiving either 19 mm Magna or Inspiris, who underwent mid-term follow-up echocardiogram were included in the study. Mid-term hemodynamic measurements evaluated by trans-thoracic echocardiogram and long-term o utcomes were compared. Patie...
