RESUMEN
Background Quantifying the fibrotic and calcific composition of the aortic valve at CT angiography (CTA) can be useful for assessing disease severity and outcomes of patients with aortic stenosis (AS); however, it has not yet been validated against quantitative histologic findings. Purpose To compare quantification of aortic valve fibrotic and calcific tissue composition at CTA versus histologic examination. Materials and Methods This prospective study included patients who underwent CTA before either surgical aortic valve replacement for AS or orthotopic heart transplant (controls) at two centers between January 2022 and April 2023. At CTA, fibrotic and calcific tissue composition were quantified using automated Gaussian mixture modeling applied to the density of aortic valve tissue components, calculated as [(volume/total tissue volume) × 100]. For histologic evaluation, explanted valve cusps were stained with Movat pentachrome as well as hematoxylin and eosin. For each cusp, three 5-µm slices were obtained. Fibrotic and calcific tissue composition were quantified using a validated artificial intelligence tool and averaged across the aortic valve. Correlations were assessed using the Spearman rank correlation coefficient. Intermodality and interobserver variability were measured using the intraclass correlation coefficient (ICC) and Bland-Altman plots. Results Twenty-nine participants (mean age, 63 years ± 10 [SD]; 23 male) were evaluated: 19 with severe AS, five with moderate AS, and five controls. Fibrocalcific tissue composition strongly correlated with histologic findings (r = 0.92; P < .001). The agreement between CTA and histologic findings for fibrocalcific tissue quantification was excellent (ICC, 0.94; P = .001), with underestimation of fibrotic composition at CTA (bias, -4.9%; 95% limits of agreement [LoA]: -18.5%, 8.7%). Finally, there was excellent interobserver repeatability for fibrotic (ICC, 0.99) and calcific (ICC, 0.99) aortic valve tissue volume measurements, with no evidence of a difference in measurements between readers (bias, -0.04 cm3 [95% LoA: -0.27 cm3, 0.19 cm3] and 0.02 cm3 [95% LoA: -0.14 cm3, 0.19 cm3], respectively). Conclusion In a direct comparison, standardized quantitative aortic valve tissue characterization at CTA showed excellent concordance with histologic findings and demonstrated interobserver reproducibility.

Coronary artery disease is among the leading current epidemiological challenges. The genetic, clinical, and lifestyle-related risk factors are well documented. The reason for specific epicardial artery locations remains unsolved. The coronary artery topography and blood flow characteristics may induce local inflammatory activation. The atherosclerotic plaque formation is believed to represent inflammatory response involving enzymatic processes co-factored by trace elements. The possible relation between trace elements and coronary artery disease location was the subject of the study. There were 175 patients (107 (61) men and 68 (39) females) in a median (Q1-3) age of 71 years (65-76) admitted for coronary angiography due to chronic coronary syndrome. The angiographic results focused on the percentage of lumen stenosis in certain arteries and were compared with the results for hair scalp trace elements. The correlation between left main coronary artery atherosclerotic plaques and nickel (Ni), zinc (Zn), and antimony (Sb) hair scalp concentration was noted. The analysis revealed a positive relation between left descending artery disease and chromium (Cr), sodium (Na), arsenic (As), and molybdenum (Mo) and a negative correlation with strontium (Sr). The atherosclerotic lesion in the circumflex artery revealed correlations in our analysis with sodium (Na), potassium (K), chromium (Cr), nickel (Ni), arsenic (As), and negative with strontium (Sr) (r) hair scalp concentrations. The negative correlations between right coronary artery disease and magnesium (Mg) and strontium (Sr) concentrations were noted. The possible explanation of different epicardial artery involvement and severity by atherosclerotic processes may lay in their topography and blood rheological characteristics that induce different inflammatory reactions co0factored by specific trace elements. The trace element concentration in the hair scalp may correlate with a particular coronary atherosclerotic involvement, including the severity of lumen reduction. This may indicate the missing link between the pathophysiological processes of atherosclerosis development and its location in coronary arteries.
RESUMEN
Introduction: Left main (LM) coronary disease is believed to represent a complex, advanced, and potentially life-threatening atherosclerotic syndrome that can be treated by either percutaneous or surgical interventions. Despite its satisfactory results, the declined number of off-pump coronary artery bypass grafting (OPCAB) is observed. Aim: To compare 10-year survival and point out possible mortality risk factors in patients referred for left main and multivessel OPCAB surgery followed by transit time bypass measurements. Material and methods: There were 159 patients (128 (81%) men and 31 (19%) women) in a median age of 66 (60-70) years enrolled in retrospective analysis who were referred to surgical intervention due to left main (51, 32%) and multivessel (108, 68%) disease. The regression analysis for long-term mortality risk and the Kaplan-Meyer survival curve were analyzed. Results: Multivariable analysis pointed female sex (HR = 1.08, 95% CI: 1.03-1.14, p = 0.001) and diabetes mellitus (HR = 6.33, 95% CI: 1.86-21.52, p = 0.003) as possible risk factors for 10-year mortality risk. There was no significant difference in Kaplan-Meyer 10-year mortality comparison between left main and multivessel disease patients treated by off-pump surgical revascularization (HR = 0.93, 95% CI: 0.40-2.13, p = 0.86). Conclusions: Off-pump surgery in the left main disease, compared to multivessel disease, represents a safe surgical technique with satisfactory long-term results. The female sex and diabetes mellitus were found as possible risk factors for 10-year mortality risk in multivariable analysis.
RESUMEN
Introduction: Global warming is claimed to be an important cardiovascular disease risk factor. The air pollution and ambient temperatures are believed to have a significant influence on increased morbidity and premature deaths. Aim: To point out possible causative factors for coronary angiography progression in patients presenting with chronic coronary syndrome. Material and methods: There were 66 patients (41 [62%] men and 25 [38%] women) with a median age of 71.5 (62-76) years, who underwent repeated coronary angiographies due to chronic coronary syndrome within a median time interval of 145 (96-296) days. In 18 (27%) patients coronary artery lesion progression was observed despite optimal pharmacotherapy. The demographical, clinical, and personalised epidemiological factors including air pollution particles and ambient temperature exposure were taken into account in the analysis. Results: In the multivariate logistic regression model with backward stepwise elimination method, tropical nights (p = 0.047) and mean daily temperatures (p = 0.043) were revealed as predictors of coronary lesion progression > 30%. The analysis of seasonal temperature changes showed significant differences related to minimal winter temperatures between both groups (p = 0.018). Conclusions: Coronary artery lesion progression can be related to either high values of daily temperatures or to low ambient temperature. The dichotomous characteristics of temperature exposure to atherosclerosis progression suggest a detrimental role of environmental extremities on human health.
RESUMEN
Background: Thoracic aortic aneurysms are often an accidental finding and result from a degenerative process. Medical therapy includes pharmacological control of arterial hypertension and smoking cessation, that slows the growth of aneurysms. An association between the dilatation of the ascending and abdominal aorta has been already reported. The aim of the study was to identify possible demographic and clinical factors that may implicate further imaging diagnostics in patients with ascending aorta dilatation. Methods: There were 181 (93 (53%) males and 88 (47%) females) patients with a median age of 54 (41-62) years who underwent cardiac magnetic resonance due to non-vascular diseases, were enrolled into retrospective analysis. Results: Multivariable analysis revealed ascending aorta dilatation (odds ratios (OR) = 7.45, 95% confidence interval (CI): 1.98-28.0, p = 0.003) and co-existence of coronary artery disease (OR = 8.68, 95% CI: 2.15-35.1, p = 0.002) as significant predictors for thoracic descending aorta dilatation. In patients with abdominal aorta dilatation, the multivariable analysis showed a predictive value of ascending aortic dilatation (OR = 14.8, 95% CI: 2.36-92.8, p = 0.004) and age (OR = 1.04, 95% CI: 1.00-1.08, p = 0.027). In addition, cut-off values were established for age groups determining the risk of thoracic aorta dilatation over 49 years and abdominal aorta dilatation over 54 years. Conclusions: The results of our analysis showed predictive factors, including ascending aorta dilatation and co-existence of coronary artery disease, particularly over 49 years of age for thoracic, while ascending aorta dilatation and age, particularly over 54 years, for abdominal aorta dilatation. These features may be considered to increase clinical vigilance in patients with aortic diameter abnormalities.
RESUMEN
The background of this review is a description of the case of a 28-year-old man with an extremely rare cardiac solitary fibrous tumor (SFT). Although this tumor was removed surgically and in the 6-month follow-up examination no relapse was noted, recurrence was observed and confirmed in the magnetic resonance imaging 4 months later. SFT prevalence, symptoms and signs, treatment options and prognosis are reviewed.
RESUMEN
Introduction: Despite increasing implementation of sophisticated and logistically challenging techniques to support patients in life-threatening conditions in the last years, there were no devoted education centres, especially in coronavirus pandemic. Aim: To assess the value of gaining evidence-based knowledge and improving the skills of physicians by means of simulation techniques in the safe use of extracorporeal technologies to support patients in the life-threatening conditions. Material and methods: In 2019, the National Education Centre for Artificial Life Support and Patient Safety and the frame program of the course of "Artificial Life Support with ECMO". was created. In years 2019-2023, we managed to organise 34 such courses for 405 physicians, which were additionally endorsed by ELSO (Extracorporeal Life Support Organisation). The physicians' cognitive, behavioural, and technical skills were evaluated before and after the courses. Results: The participants' gender was well balanced (54% men and 46% women). Most of them (mainly at the age between 31-40 years) presented more than 5 years of clinical experience, predominantly in anaesthesiology and intensive care (63%). Of note, 54% of them had no experience with ECMO application. In all detailed aspects of cognitive, behavioural, and technical assessment and knowledge scores, significant improvement was observed after the course. Conclusions: The development of a simulation-based education centre was found to be an invaluable achievement that enabled not only successful standardised training and testing of novel or previously accepted procedures, but also the upgrading of technical skills, even in the challenging COVID-19 pandemic period.
RESUMEN
BACKGROUND: This study investigated the impact of complete revascularization (CR) and incomplete revascularization (IR) on long-term survival in patients undergoing isolated coronary artery bypass grafting (CABG) using multiple arterial graft (MAGs) or a single artery with saphenous vein grafts (SAGs). METHODS: Between January 2006 and December 2020, 12,625 patients underwent CABG and were divided into 4 groups: MAG CR (n = 1066), MAG IR (n = 286), SAG CR (n = 8360), and SAG IR (n = 2913). Inverse probability of treatment weighting based on the generalized propensity score was used to minimize imbalance between the groups. RESULTS: In the weighted cohort, median follow-up time was 8.35 years (interquartile range, 5.01-11.6 years). MAG CR was associated with similar long-term survival compared with MAG IR (hazard ratio [HR], 0.79; 95% CI, 0.60-1.03; P = .084). SAG CR was associated with improved long-term survival compared with SAG IR (HR, 0.67; 95% CI, 0.52-0.84; P = .01). MAG CR was associated with better long-term survival compared with SAG CR (HR, 0.45; 95% CI, 0.35-0.57; P < .001). Moreover, MAG IR was protective compared with SAG IR (HR, 0.62; 95% CI, 0.45-0.85; P = .033). Additional analysis was performed comparing perfect CR vs imperfect CR vs IR in MAG and SAG patients, separately. In the weighted sample of MAG, there were no differences in the long-term survival between perfect CR, imperfect CR, and IR. However, in the weighted sample of the SAG cohort, SAG perfect CR was associated with improved survival compared with SAG imperfect CR (HR, 0.81; 95% CI, 0.0.72-0.92; P = .001). Whereas, SAG perfect and imperfect CR were both associated with improved survival compared with SAG IR (HR, 0.51; 95% CI, 0.0.35-0.87; P = .006 and HR, 0.72; 95% CI, 0.64-0.82; P < .001), respectively. CONCLUSIONS: MAG CR is associated with better survival compared with SAG CR. If IR is inevitable, patients with MAG IR had better long-term survival compared with patients receiving SAG IR. Moreover, similar long-term survival is observed whether perfect CR, imperfect CR, or IR is achieved in the MAG population but not in SAG patients.
RESUMEN
BACKGROUND: An imbalance between pro- and anti-inflammatory mechanisms is indicated in the pathophysiology of atherosclerotic plaque. The coronary artery and carotid disease, despite sharing similar risk factors, are developed separately. The aim of this study was to analyze possible mechanisms between trace element hair-scalp concentrations and whole blood counts that favor atherosclerotic plaque progression in certain locations. METHODS: There were 65 (36 (55%) males and 29 (45%) females) patients with a median age of 68 (61-73) years enrolled in a prospective, preliminary, multicenter analysis. The study group was composed of 13 patients with stable coronary artery disease (CAD group) referred for surgical revascularization due to multivessel coronary disease, 34 patients with carotid artery disease (carotid group) admitted for vascular procedure, and 18 patients in a control group (control group). RESULTS: There was a significant difference between the CAD and carotid groups regarding lymphocyte (p = 0.004) counts. The biochemical comparison between the coronary and carotid groups revealed significant differences regarding chromium (Cr) (p = 0.002), copper (Cu) (p < 0.001), and zinc (Zn) (p < 0.001) concentrations. Spearman Rank Order Correlations between lymphocyte counts and trace elements in the analyzed groups were performed, revealing a strong correlation with zinc (R = 0.733, p < 0.001) in the control group (non-CAD, non-carotid). CONCLUSION: Significant differences in hair-scalp concentrations related to atherosclerosis location were observed in our analysis. The interplay between zinc concentration and lymphocyte count may play a pivotal role in cardiovascular disease development.
RESUMEN
INTRODUCTION: Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis (AS) in patients at intermediate and high surgical risk. Circulating extracellular vesicles (EVs) are nanoparticles involved in cardiovascular diseases. We aimed to (i) determine the effect of TAVI on plasma concentrations of five EV subtypes and (ii) evaluate the predictive value of EVs for post-TAVI outcomes. METHODS: Blood samples were collected 1 day before TAVI and at hospital discharge. Concentrations of EVs were evaluated using flow cytometry. RESULTS: Concentration of leukocytes EVs decreased after TAVI, compared to the measurement before (p = 0.008). Among 123 patients discharged from the hospital, 19.5% experienced MACCE during the median of 10.3 months. Increased pre-TAVI concentration of phosphatidylserine-exposing EVs was an independent predictor of MACCE in multivariable analysis (OR 5.313, 95% CI 1.164-24.258, p = 0.031). CONCLUSIONS: Patients with increased pre-TAVI concentration of procoagulant, PS-exposing EVs have over fivefold higher odds of adverse outcomes.
RESUMEN
(1) Background: Estimates suggest that up to 10% of global annual cardiovascular deaths could be related to environmental factors. Not only air pollution components, but also noise exposure and climate changes, are highlighted as nontraditional causes of cardiovascular morbidity. The aim of this study was to identify possible urbanization risk factors for the progression of coronary artery disease in a group of patients with chronic coronary syndrome. (2) Method: There were 77 patients (50 (65%) males and 27 (35%) females) with a median age of 70 (60-74) years who underwent repetitive angiography due to chronic coronary syndrome between 2018 and 2022. The Gensini score was calculated for assessment of coronary artery disease advancement. Environmental factors including neighboring developments were taken into account in this analysis, including housing, commercial, and industrial developments within 300, 500, and 700 m distances (buffer) from the place of habitation. (3) Results: The multivariable analysis results for prediction of Gensini score progression in relation to 700 m buffer urbanization pointed out the significance of hyperlipidemia (OR: 4.24, 95% CI 1.34-13.39, p = 0.014), initial Gensini score (OR: 1.02, 95% CI 1.00-1.05, p = 0.112), and neighborhood housing (OR: 0.03, 95% CI 0.01-0.49, p = 0.025). (4) Conclusions: Hyperlipidemia and housing neighborhood can be regarded as possible factors for coronary disease progression in patients with chronic coronary syndrome with the use of optimal medical therapy.
RESUMEN
PURPOSE: Mitral valve surgery in children involves correcting congenital and acquired pathologies, with a reported mortality rate of 0.9%. Low cardiac output syndrome (LCOS) is a serious complication with the incidence of 20-25%. The aim of the study was to estimate possible prognostic factors of LCOS in children undergoing mitral valve procedure. MATERIAL AND METHOD: This single-center retrospective analysis enrolled children aged <18 years who underwent mitral valve surgery during 24 year period. Preoperative clinical and laboratory parameters, and operative factors were analyzed. RESULTS: Thirty consecutive pediatric patients (11 (37%) males and 19 (63%) females) in median (Q1 - Q3) age of 57 (25-115) months, who underwent mitral valve replacement, were included. The 30-day mortality was 7% (2 patients) and was related to postoperative multiorgan failure. LCOS occurred in 8 (27%) children. The receiver operator curve (ROC) analysis established parameters that have predictive value for LCOS occurrence: cardiopulmonary bypass (CPB) time, with 89 âmin as optimal cut-off point (AUC â= â0.744, p â= â0.011) yielding sensitivity of 100% and specificity of 42.9%; left ventricular ejection fraction (LVEF) â< â60 % (AUC â= â0.824, okp â= â0.001) with sensitivity of 62.5% and specificity of 93.75%; and red blood cell distribution width (RDW) above 14.5 % (AUC â= â0.840, p â< â0.001; sensitivity of 87.5% and specificity of 75%). CONCLUSIONS: In mitral valve replacement in pediatric patients, CPBtime above 89 âmin, preoperative LVEF below 60% and preoperative RDW above 14.5% can be regarded as the potential predictors of LCOS.

BACKGROUND: The objective of this multicenter study aimed to investigate the impact of sex on long-term survival among patients with multivessel coronary artery disease undergoing coronary artery bypass grafting (CABG) using multiple arterial grafting (MAG) or a single artery with saphenous vein grafts. MATERIALS AND METHODS: Data were obtained from the Polish National Registry of Cardiac Surgery Procedures database. This study included 81 136 patients who underwent CABG for multivessel disease between January 2012 and December 2020 (22.9 were women and 77.1% were men). MAG was performed in 8.3 and 11.7% of female and male patients, respectively. A 1:1 propensity score (PS)-matching was performed. Long-term mortality was compared between matched groups of men and women. Subgroup analyses of patients aged <70 and ≥70 years, with an ejection fraction (EF) >40% and ≤40%, and with and without diabetes, obesity, peripheral artery disease (PAD), or chronic lung disease (CLD) were performed separately in women and men. RESULTS: MAG was associated with lower long-term mortality than saphenous vein grafts in 1528 PS-matched female pairs [hazard ratio (HR): 0.74; 95% CI: 0.59-0.92; P =0.007) and 7283 PS-matched male pairs (HR: 0.80; 95% CI: 0.72-0.88; P <0.001). Subgroup analyses confirmed the results among female patients aged <70 years, with diabetes and EF >40%, and without PAD or CLD, and of male patients aged <70 and ≥70 years; with EF >40%; with or without diabetes, obesity, or PAD; and without CLD. CONCLUSIONS: In patients undergoing CABG, MAG was associated with significantly improved survival in both sexes. The long-term benefits of MAG observed across subgroups of men and women support the consideration of a multiarterial revascularization strategy for a broader spectrum of patients.

BACKGROUND: The coronary artery disease (CAD) remains the leading cause of morbidity that is characterized by broad spectrum of symptoms. Up to 30% of performed angiographies reveal normal coronary arteries. The aim of the study was to find simple predictor for significant epicardial artery stenosis among patients with chronic coronary syndrome. METHODS: There were 187 patients (131 (709%) men and 56 (30%) women) in the median (Q1-Q3) age of 67 [58-72] presenting with stable CAD symptoms enrolled into the present retrospective analysis. The demographical, clinical and laboratory characteristics between patients with normal and significant coronary artery stenosis were compared. RESULTS: The multivariable analysis revealed coexistence of hypercholesterolemia as significant differentiation factor (odds ratio [OR]: 4.38, 95% confidence interval [CI]: 1.78-10.80, p = 0.001) for significant CAD and inverse relation to serum high density lipoprotein (OR: 0.19, 95% CI: 0.05-0.72, p = 0.015) and relation to creatinine concentration (OR: 1.03, 95% CI: 1.00-1.05, p = 0.012). Among whole peripheral blood count analysis, the significant relation was noticed to be hemoglobin concentration (OR: 1.09, 95% CI: 1.10-1.18, p = 0.022) and monocyte count (OR: 32.3, 95% CI: 1.09-653.6, p = 0.017). Receiver operator curve revealed (AUC: 0.641, p = 0.001) with the optimal cut-off value above 0.45 K/uL for monocyte, yelding sensitivity of 81.82% and specificity of 58.06%. CONCLUSIONS: The peripheral monocyte count above 0.45 k/uL may be considered as a predictor of significant coronary artery disease in symptomatic patients with chronic coronary syndrome.
RESUMEN
Introduction: The role of immune system activation in development and progression of atherosclerotic plaques has been postulated. Previous studies on inflammation have focused on the severity of coronary disease, the risk of acute coronary syndrome, and the prediction of outcomes based on hematological indices obtained from whole blood count analysis. Aim: To analyze simple data of the whole blood count in relation to the location of calcified atherosclerotic lesions in patients treated with coronary rotational atherectomy (RA). Material and methods: Eighty-one patients (57 (70%) males, mean (SD) age of 70.4 ±8 years) who underwent RA were enrolled in the study. The study group was divided into two subgroups depending on the proximal (group 1) and non-proximal (group 2) location of the culprit lesions in coronary arteries. The angiographic results were compared with demographic and clinical data and whole blood count analysis. Results: The multivariable analysis revealed the predictive value of low neutrophil (OR = 0.75, 95% CI: 0.58-0.97, p = 0.030) and lymphocyte counts (OR = 0.27, 95% CI: 0.11-0.68, p = 0.005) for the proximal location of the culprit lesions. In the ROC analysis, combined neutrophil and lymphocyte counts showed the best prediction of proximal location, with the area under the curve of 0.747 (p < 0.001), yielding a sensitivity of 79.07% and specificity of 73.68%. Conclusions: The lower neutrophil and lymphocyte counts in peripheral blood count analysis may be more representative of proximal calcified coronary lesions. The relationship between neutrophil and lymphocyte blood count and calcific atherosclerotic plaque location can indicate the inflammatory background of epicardial atheroma formation and distribution.
RESUMEN
Background: Coronary artery atherosclerosis development and progression are related to generic, clinical, and lifestyle factors combined with inflammatory activation. The relationship between trace element concentration and morbidity is under investigation to gain a clearer understanding of underlying pathological processes. Methods: Thirty-five consecutive patients (22 males and 13 females) with a median [interquartile range (IQR)] age of 67 (61-73) years presenting with anginal symptoms were included in the single center prospective analysis in 2022 and divided into a epicardial coronary artery disease (CAD) and non-CAD group. Scalp hair chemical analysis and inflammatory markers from a peripheral blood count were analyzed. Results: The correlation analysis of elements and inflammatory indexes showed statistical significance between median hair lithium (Li) concentration and the systemic inflammatory index (SII) (r = -0.476, p = 0.046), antimony (Sb) (r = -0.521, p = 0.028) followed by chromium (Cr) (r = -0.478, p = 0.045) and iron (Fe) (r = -0.604, p = 0.008) in the CAD group. Similar correlations were not found in non-CAD group. Conclusions: The correlation between scalp hair lithium (Li), antimony (Sb), chromium (Cr) and iron (Fe) concentration and the systemic inflammatory index (SII) were revealed only in patients with coronary artery disease. Our analysis identified a strong correlation between inflammatory activation and iron concentration.
