Abstract
Although transcatheter aortic valve replacement (TAVR) is safe and effective, mortality and bleeding events post procedure are important. The present study investigated the changes in hematologic parameters to evaluate whether they predict mortality or major bleeding. We enrolled 248 consecutive patients (44.8% male; mean age 79.0 ± 6.4 years) undergoing TAVR. In addition to demographic and clinical examination, blood parameters were recorded before TAVR, at discharge, 1 month and 1 year. Hemoglobin levels before TAVR 12.1 ± 1.8 g/dL, 10.8 ± 1.7 g/dL at discharge, 11.7 ± 1.7 g/dL at first month, 11.8 ± 1.4 g/dL at first year (Hemoglobin values compared with pre-TAVR, P < .001, P = .019, P = .047, respectively). Mean platelet volume (MPV) before TAVR 8.72 ± 1.71 fL, 8.16 ± 1.46 fL at discharge, 8.09 ± 1.44 fL at first month, 7.94 ± 1.18 fL at first year (MPV values compared with pre-TAVR, P < .001, P < .001, P < .001, respectively). Other hematologic parameters were also evaluated. Hemoglobin, platelet count, MPV, and red cell distribution width before the procedure, at discharge, and at the first year did not predict mortality and major bleeding in receiver operating characteristic analysis. After multivariate Cox regression analysis, hematologic parameters were not independent predictors of in-hospital mortality, major bleeding, and death at 1 year after TAVR.

Abstract
OBJECTIVE Calcific aortic stenosis (AS) is the most common form of calcific aortic valve disease. Many matrix metalloproteinase (MMP) have been shown to be expressed in aortic sclerosis and contribute to valve fibrosis and calcification. We investigated the relationship between Pregnancy-Associated Plasma Protein-A (PAPP-A) and AS. METHODS Sixty-one patients who referred to our cardiology clinic having AS diagnosed with transthoracic echocardiography and thirty control subjects were included in this study. The patient group was divided into two groups as mild and moderate-severe AS in terms of echocardiography results. Levels of C-reactive protein (CRP), insulin-like growth factor-1 (IGF-1) and PAPP-A were measured. RESULTS There was statistically significant difference between the patient and control group for PAPP-A (p = 0.009). In addition, the difference between MPV, IGF-1 and PAPP-A levels of control and AS groups was found. We found that serum PAPP-A level was an independent predictor of AS (B = 0.107, p = 0.01) by logistic regression analysis. In linear regression analysis, a significant correlation was found for AS severity with MPV, IGF-1 and PAPP-A levels, respectively (p = 0.025, p = 0.004, p = 0.035). It was revealed that PAPP-A and IGF-1 were negatively correlated (r = -0.327, p = 0.002). Correlation of serum PAPP-A level with echocardiographic parameters was no observed. CONCLUSION The level of PAPP-A may be a marker used in diagnosis rather than a marker used to determine the severity of AS. Studies with larger patient populations may further explain the role of PAPP-A in the diagnosis and treatment of AS.

Abstract
Background/aim From a pathophysiological point of view, inflammation is thought to be more dominant in bicuspid aortic valve (BAV) stenosis than tricuspid aortic valve (TAV) stenosis. Our study aimed to determine the association between monocyte to high-density lipoprotein cholesterol (HDL-C) ratio (MHR), a new inflammatory marker, and the speed of progression of stenosis and pathophysiology of BAV stenosis. Materials and methods A total of 210 severe aortic stenosis patients (70 consecutive BAV patients, 140 matched TAV patients) were retrospectively enrolled in the study. Clinical and echocardiographic data and laboratory results related to our research were collected retrospectively from the patients’ records. MHR was measured as the ratio of the absolute monocyte count to the HDL-C value. Results Seventy BAV (mean age: 72.0 ± 9.1 years, 42.9% female) and 140 TAV patients (mean age: 77.9 ± 8.3 years, 51.4% female) with severe aortic stenosis were enrolled in this study. There was no difference between the two groups in terms of another baseline demographic or clinic findings except age (P < 0.001). Monocyte count, hemoglobin level, mean platelet volume was significantly higher, and HDL-C level was significantly lower in the BAV group, while other lipid and CBC parameters were found to be similar. In the multivariate analysis, MHR (P = 0.005, 95% CI: 0.90–0.98) and, as expected, age (P = 0.001, 95% CI: 1.02–1.11) were found to be significant as the independent predictor of BAV, after adjusting for other risk factors. Conclusion Our study showed a significant correlation between increased MHR and BAV. MHR was determined as a significant independent predictor for the speed of progression and diagnosis of severe BAV stenosis in multivariate analysis.

Abstract
BACKGROUND Patients with a bicuspid aortic valve (BAV) are at risk of developing valve deterioration and aortic dilatation. We aimed to investigate whether blood biomarkers are associated with disease stage in patients with BAV. METHODS Serum levels of high sensitivity C-reactive protein (hsCRP), high sensitivity troponin T (hsTnT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and total transforming growth factor-beta 1 (TGF-ß1) were measured in adult BAV patients with valve dysfunction or aortic pathology. Age-matched general population controls were included for TGFß-1 measurements. Correlation analyses and multivariable linear regression were used to determine the association between (2log-transformed) biomarker levels and aortic valve regurgitation, aortic valve stenosis, aortic dilatation, or left ventricular function. RESULTS hsCRP and hsTnT were measured in the total group of 183 patients (median age 34 years, 25th-75th percentile 23-46), NT-proBNP in 162 patients, and TGF-ß1 beta in 108 patients. Elevated levels of NT-proBNP were found in 20% of the BAV patients, elevated hsTnT in 6%, and elevated hsCRP in 7%. Higher hsTnT levels were independently associated with aortic regurgitation [odds ratio per doubling (OR2log) 1.34, 95% CI 1.01;1.76] and higher NT-proBNP levels with aortic valve maximal velocity (ß2log 0.17, 95%CI 0.07;0.28) and aortic regurgitation (OR2log 1.41, 95%CI 1.11;1.79). Both BAV patients with (9.9 ± 2.7 ng/mL) and without aortic dilatation (10.4 ± 2.9 ng/mL) showed lower TGF-ß1 levels compared to general population controls (n = 85, 11.8 ± 3.2 ng/mL). CONCLUSIONS Higher NT-proBNP and hsTNT levels were associated with aortic valve disease in BAV patients. TGF-ß1 levels were lower in BAV patients than in the general population, and not related to aortic dilatation. Longitudinal data are needed to further investigate the prognostic value of biomarkers in these patients.

Abstract
Background Aortic root ectasia might induce hemostatic disorders in patients with Marfan syndrome (MFS) via altered blood flow and rheology. The aim of this study was to explore the hemostasis in patients with MFS compared with healthy controls. Methods In this cross-sectional case-control study we included patients with verified MFS (n=51) and sex- and age-matched healthy controls (n=50). Main criteria were the aortic root in echocardiography and cardiac magnetic resonance imaging (MRI), and the coagulation status. Results When compared with healthy controls, patients with MFS showed significantly increased diameters of the aortic roots (43.0±7.72 vs. 28.8±3.74 mm, P<0.001) and aortic Z-scores (4.36±2.77 vs. 0.948±1.09, P<0.001), considerably higher values of Multiplate® tests (e.g., MP-ADP: 878.4±201.7 vs. 660.4±243.6 AU*min, P<0.001) and PFA-100® tests (PFA Col/ADP: 102.5±45.5 vs. 91.1±46.2 s, P<0.05), PTT (30.0±3.91 vs. 28.7±2.50 s, P<0.05) and D-dimers (0.488±0.665 vs. 0.254±0.099 mg/L, P<0.001). In MFS von Willebrand factor (VWF) activity (81.9%±41.8% vs. 106.3%±41.5%, P<0.05) and antigen (93.8%±43.9% vs. 118.8%±47.8%, P<0.05) and factor VIII activity (108.9%±29.6% vs. 126.7%±28.4%, P<0.05) were reduced. Significant positive correlations were found between aortic diameters and D-dimers (all P<0.05), as well as PFA Col/ADP (all P<0.01) in MFS patients. Factor VIII activity correlated significantly negatively with the diameter of the aortic root in MFS (r=-0.55, P<0.05). Conclusions In conclusion, our study reveals hemostatic deviations in patients with MFS. Further studies are necessary to understand the causal relationship and the exact pathomechanism.

Abstract
The neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) are emerging indirect blood markers to roughly reflect the inflammation level in our body while some pathological changes occurring in aortic valve tissue. Few recent studies demonstrated that NLR is related to calcific aortic valve disease (CAVD). However, the extent of the relationship between them and the impact of CRP on CAVD are not clear. This study aimed to investigate the diagnostic influence and surgical predictive effect of NLR and CRP on CAVD.A total of 278 consecutive patients with CAVD (123 patients with bicuspid aortic valve and others with tricuspid aortic valve) and 108 healthy individuals who were included in the control group were enrolled in the study. The NLR was calculated from the complete blood count, and the CRP was measured from peripheral blood samples. Echocardiography was used to evaluate the severity of aortic stenosis. Intraoperation/postoperation indicators were collected in 166 patients from the total consecutive patients who underwent aortic valve replacement (AVR) alone.Significantly higher NLR was measured in both the BAV group (1.96 ± 0.78 versus 0.97 ± 0.15, P < 0.001) and the TAV group (2.51 ± 2.03 versus 0.97 ± 0.15, P < 0.001) compared with the control group. Moreover, the NLR level was significantly higher (P < 0.001) and the CRP level was significantly lower (P = 0.007) of the TAV group than that of the BAV group; a significant positive correlation between the NLR and the maximum gradient of aortic valve was detected. Furthermore, there was a moderate correlation between the NLR and the postoperative mechanical ventilation time.Our results indicated that the NLR and CRP were novel and useful predictive factors in patients with CAVD, and these two potential factors have guiding significance for the prediction of different pathological typing (BAV or TAV). Higher NLR level will not extend the cardiopulmonary bypass time (CPB); however, it will prolong the operation time and the postoperative mechanical ventilation time.

Abstract
OBJECTIVES The importance of thrombocytopenia (TP) has been discussed previously. However, data are still limited, especially on predictors of TP. We sought to investigate predictors of TP after transcatheter aortic valve replacement (TAVR), in particular, clinically significant TP. METHODS We reviewed a total of 123 consecutive patients undergoing TAVR in our medical center. They were stratified into 3 groups according to the nadir platelet count post-TAVR: no/mild TP, moderate TP, and severe TP. Clinically significant TP, also known as major TP, was defined as moderate-to-severe TP (a nadir platelet count <100 × 109/L and a >50% decrease in platelet count). RESULTS Baseline platelet, baseline hemoglobin, general anesthesia (GA), valve malpositioning and post-TAVR left ventricular ejection fraction were found to be predictors of post-TAVR nadir platelet count. Major TP was associated with a higher risk of major bleeding (OR 3.524, 95% CI 1.546-8.031) and 1-month mortality (OR 11.226, 95% CI 1.208-104.328). Age (OR 1.110, 95% CI 1.014-1.215) and GA (OR 6.494, 95% CI 2.058-20.408) were predictors of major TP. CONCLUSION Post-TAVR nadir platelet count can be predicted based on baseline and procedural data. Old age and GA contribute to clinically significant TP.

Abstract
BACKGROUND/AIM Transcatheter aortic valve implantation (TAVI) is an innovative approach to the treatment of aortic stenosis (AS) as an alternative to surgery in high-risk patients. Mean platelet volume (MPV) is considered an indicator of endothelial dysfunction, platelet function, and activation. In this study, we aimed to investigate MPV changes in patients undergoing TAVI. MATERIALS AND METHODS This study included 100 patients diagnosed with symptomatic severe AS and treated with TAVI between July 2011 and August 2013. Hematological parameters of the patients were examined prior to the procedure and 24 h, 1 month, and 6 months after TAVI. RESULTS A statistically significant change in patients' MPV was detected after TAVI compared to the baseline situation (P: 0.001). While no statistically significant change was observed on the first day after TAVI, at discharge, compared to the baseline situation, a statistically significant decrease was seen 1 month and 6 months after discharge. CONCLUSION We have demonstrated a decrease in MPV after surgery compared to the value before surgery. We have sought to propound the change in MPV as an indication of endothelial function after TAVI.

Abstract
Mean platelet volume (MPV) and platelet distribution width (PDW) can help diagnose cardiovascular pathologies. In this study, we aimed to demonstrate the changes in platelet (PLT) indices in children diagnosed with bicuspid aortic valve (BAV) with mild stenosis and without stenosis to compare patients with mild stenosis with those without stenosis. A total of 73 children diagnosed with BAV (30 patients with mild stenosis and 43 without stenosis) with a mean age 9.73 ± 5.01 years and a control group were included in the study. Mean MPV value was significantly lower in the control group compared with patients with BAV with mild stenosis and patients without stenosis (p = 0.001, and p < 0.01, respectively). MPV was significantly greater in patients with mild stenosis than in patients without stenosis (p = 0.049 and p < 0.05, respectively). Patients with mild stenosis had a significantly greater mean PDW value compared with patients without stenosis and the control group (p = 0.024 and p < 0.05, respectively). There was no significant difference between patients without stenosis and the control group with respect to mean PDW value (p > 0.05). In conclusion, the results of this study demonsrate that children with BAV either with or without stenosis have increased MPV; the ones with mild stenosis have even greater values than the ones without stenosis. It emphasizes the risk of thrombosis in children with BAV.

Abstract
We aimed to assess the effective factors on high mean platelet volume (MPV) in patients with stable coronary artery disease (CAD). A total of 411 patients (247 males and 164 females; mean age: 61.7 ± 9.9 years) with angiographically proven CAD were included. The patients were divided into 2 groups according to the median MPV value (MPVlow group <9.5 fL and MPVhigh group ≥9.5 fL). The SYNTAX score, high sensitive C-reactive protein (hsCRP) levels, and frequencies of diabetes and hypertension were higher in MPVhigh group compared to MPVlow group. Aortic distensibility (AD) and platelet count of patients in MPVhigh group were lower than patients in MPVlow group ( P < .05, for all). Multivariate linear regression analysis showed that MPV was independently related with diabetes (β = 0.135, P = .007), hsCRP (β = 0.259, P < .001), platelet count (β = −0.144, P < .001), and AD (β = −0.425, P < .001). High MPV value is independently related to AD, as well as diabetes, hsCRP, and platelet count in patients with stable CAD.
