RESUMO
Hospital-based health technology assessment (HB-HTA) is a scientific approach to inform decisions on investments in health technologies across multiple medical specialties at a hospital level. HB-HTA is not currently practiced in Poland. This study aimed to assess the need for HTA in Polish hospitals, including perceived benefits and challenges of adoption of HB-HTA in Poland, expected demand for training in HB-HTA, and perception of incentives to foster HB-HTA adoption. Study data were gathered using the computer-assisted telephone interview (CATI) technique. Between June and August 2021, 50 interviews were conducted: 52% of respondents had over 10 years of experience, and 40% comprised the highest degree reference hospitals. A high or moderate need for HB-HTA was reported by 86% of managers. The ability to indicate valuable and affordable medical technologies was the main reported benefit of HB-HTA (90%). The main obstacle to the adoption of HB-HTA was the shortage of competent staff (84%). The most important incentives to adopt HB-HTA were free training and premium financing from the National Health Fund. There is a clear need for HB-HTA in Polish hospitals despite some important obstacles.

Introduction: Transcatheter aortic valve implantation (TAVI) is an effective treatment of significant aortic stenosis. Paravalvular leaks (PVLs) are one of the most common complications after the procedure. Objectives: The aim of this study was to assess whether the aortic root morphology affects the occurrence of PVL after TAVI. Patients and methods: We enrolled 50 patients with bicuspid and 50 patients with tricuspid aortic valve who underwent multislice computed tomography (MSCT) and transthoracic echocardiography prior to TAVI. The dimensions of the aortic root were assessed by MSCT. PVL after TAVI was assessed by transthoracic echocardiography. Patients were divided in 2 groups according to the PVL severity: less than moderate PVL (n = 80) and moderate or worse PVL (n = 20), and comparisons between the groups were performed. Results: Patients with at least moderate PVL, compared with those with less than moderate PVL, had greater mean (SD) area (5.2 [1.1] cm2 vs 4.7 [0.8] cm2; P = 0.02), perimeter (8.4 [0.9] cm vs 7.9 [0.7] cm; P = 0.01), and long axis (29.5 [2.7] mm vs 28 [2.7] mm; P = 0.04) of the aortic annulus and greater mean (SD) area (5.3 [1.3] cm2 vs 4.7 [1.1] cm2; P = 0.04) and perimeter (8.6 [1.1] cm vs 8.1 [0.9] cm; P = 0.02) of the left ventricular outflow tract. In multivariable analysis, bicuspid aortic valve disease, interventricular septum hypertrophy, greater left ventricular outflow tract, and postdilatation were significant predictors of moderate PVL following TAVI. Conclusions: The assessment of the aortic root morphology with MSCT can be helpful in predicting PVL after TAVI.

Available prediction models are inaccurate in elderly who underwent transcatheter aortic valve implantation (TAVI). The aim of present study was to analyze the separate and combined prognostic values of baseline HDL-C and C-reactive protein (CRP) levels in patients treated successfully with TAVI who had complete 2-year follow-up. We analyzed 334 patients treated with TAVI from 01/2010 to 07/2017 who had measurements of HDL-C and CRP on admission or during qualification for the procedure. Baseline HDL-C ≤46 mg/dl (areas under the curve [AUC]â¯=â¯0.657) and CRP ≥0.20 mg/dl (AUCâ¯=â¯0.634) were predictive of 2-year mortality. After stratification with both cutoffs, patients with low HDL-C and concomitant high CRP most often had LVEF ≤50% and were high risk as per EuroSCORE II. Those with isolated CRP elevation had the lowest frequency of LVEF ≤50%, but more sarcopenia (based on psoas muscle area). After adjustment in the multivariate analysis for other identified predictors including EuroSCORE II and statin therapy, isolated HDL-C ≤46 mg/dl (identified in 40 patients) and isolated CRP ≥0.20 mg/dl (nâ¯=â¯109) were both independent predictors of 2-year mortality (hazard ratio [HR]â¯=â¯2.92 and HRâ¯=â¯2.42, respectively) compared with patients with both markers within established cutoffs (nâ¯=â¯105) who had the lowest 2-year mortality (9.5%). Patients with both markers exceeding cutoffs (nâ¯=â¯80) had the highest risk (HRâ¯=â¯4.53) with 2-year mortality of 42.5%. High CRP was associated with increased mortality within the first year of follow-up, whereas low HDL-C increased mortality in the second year. The combination of both markers with EuroSCORE II enhanced mortality prediction (AUCâ¯=â¯0.697). In conclusion, low baseline HDL-C and high CRP jointly contribute to the prediction of increased all-cause mortality after TAVI.

BACKGROUND: Dual antiplatelet therapy (DAPT) is recommended prophylaxis after transcatheter aortic valve implantation (TAVI). The usefulness of platelet reactivity (PLTR) tests in predicting the safety of periprocedural DAPT in the TAVI population is unknown. AIM: To analyze the value of aspirin/clopidogrel PLTR testing in predicting the risk of in-hospital TAVI-related bleeding. METHODS: PLTR, expressed as P2Y12/aspirin reaction units (PRU/ARU), was performed using optical aggregometry with the VerifyNow® device, in the 24h before and on the sixth day after TAVI. Follow-up was by telephone. Bleeding was defined according to VARC-2, and comprised in-hospital, major and life-threatening events. RESULTS: Overall, 100 patients undergoing TAVI were included; 30 (30%) had bleeding. Clopidogrel PLTR before TAVI (area under the curve [AUC] 0.686, 95% confidence interval [CI] 0.542-0.808; P=0.02) and after TAVI (AUC 0.970, 95% CI 0.904-0.995; P<0.001) correlated with bleeding, with PRU cut-off values of ≤204 and ≤124 as bleeding predictors, respectively. A significant periprocedural decrease in clopidogrel PLTR was noted, with a PRU drop of >78 as bleeding predictor (AUC 0.851, 95% CI 0.725-0.935; P<0.001). Only postprocedural aspirin PLTR was associated with bleeding (AUC 0.697, 95% CI 0.585-0.794; P=0.008). Follow-up (359±73 days after TAVI) included 85 patients (85%) (after exclusion for in-hospital death [n=4] and lack of contact [n=11]). Major bleeding was noted in four patients (4.7%), all on combined prophylaxis. CONCLUSIONS: TAVI-related bleeding occurs mainly during the procedure or in the early postprocedural period. Testing of periprocedural clopidogrel PLTR, but not aspirin PLTR, seems useful because of its predictive value for TAVI-related bleeding. PLTR testing suggests that premedication with clopidogrel, enhanced response to clopidogrel early after TAVI and significant periprocedural drop in clopidogrel PLTR might increase the risk of TAVI-related bleeding.

UNLABELLED: Serum interleukin-6 (IL-6) level might be used to aid in diagnosis of infective endocarditis (IE), especially when blood cultures are negative. One of typical acute phase proteins is C-reactive protein (CRP), often served as an additional inflammation maker. The aim of the study was to compare serum IL-6 and CRP concentrations assessment in diagnosis and monitoring of IE. The study group consisted of 40 patients with ongoing IE and valvular heart diseases. Two control groups consisted of patients with valvular heart diseases: 15 without infection and another 15 with urinary tract infection. The diagnosis of IE was established according to the Duke University criteria; in 34 patients positive blood cultures were found. Serum IL-6 and CRP were measured on three occasions after diagnosis of IE was established and during antimicrobial treatment (mean period 14 +/- 7 days) by ELISA. Usefulness of both parameters for IE diagnosis were described. Reference values were defined as 0-12.5 pg/ml for IL-6, and 0-10 mg/l for CRP. Mean concentrations of IL-6 and CRP in patients with IE (37 +/- 44.3 pg/ml and 27.1 +/- 23.9 mg/l) were significantly higher than in controls: with urinary tract infection (9.1 +/- 4.42 pg/ml and 6.95 +/- 4.39 mg/l) and without infection (3.95 +/- 1.4 pg/ml and 2.21 +/- 0.96 mg/l). CRP concentration was not significantly correlated with IL-6 (r = 0.51, p = 0.07). The significant tendency of consecutive IL-6 concentrations to decrease (from 37 +/- 44.3 to 8.7 +/- 5.7 pg/ml), without decrease of CRP (from 27.1 +/- 23.9 mg/l to 22 +/- 18.3 mg/l) was found. CONCLUSIONS: 1. Elevated serum IL-6 and CRP levels may suggest ongoing IE. 2. Sensitivity, specificity, positive and negative predictive value are nonsignificantly higher for IL-6 than CRP. 3. Combined assessment of serum IL-6 and CRP concentration has no higher value in diagnosis of IE. 4, IL-6 level decrease is faster than CRP during antimicrobial treatment, and it helps better and faster monitoring of treatment.
