Transcatheter Closure or Surgery for Symptomatic Paravalvular Leaks: The Multicenter KISS Registry.

BACKGROUND: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

In-hospital outcomes of patients undergoing emergent surgical treatment in patients with infective endocarditis.

BACKGROUND: Infective endocarditis is a serious heart disease that may cause several different clinical conditions and can need urgent surgical therapy. In our study, we aimed to evaluate the patients with infective endocarditis undergoing acute surgical treatment results in-hospital mortality. METHODS: A total of 107 consecutive patients with infective endocarditis undergoing acute surgical therapy were included in our retrospective study. The patients were divided into two groups according to the presence of in-hospital mortality as Group 1 without in-hospital mortality (n=89) and Group 2 with in-hospital mortality (n=18). The demographic, laboratory, and clinical parameters were evaluated in both groups. RESULTS: The mean age (50±14; 64±14, P<0.001) and the incidence of chronic renal failure (9 [10.1%]; 8 [44.4%], P=0.001) were higher in Group 2 while the ejection fraction was lower in Group 2 (50.0±9.3; 44.6±12.9, P=0.039). The incidence of positive blood culture was also higher in Group 2 (41 [46.1]; 14 [77.8], P=0.014). Aortic bioprosthesis operation (2 [2.2]; 6 [33.3], P<0.001) and mitral bioprosthesis operation (4 [4.5]; 5 [27.8], P=0.008) were higher in Group 2 as well as the incidence of septic shock was also higher in Group 2 (1 [1.1]; 3 [16.7], P=0.015). In addition, in multivariate logistic regression analyses, advanced age (odds ratio [OR]: 1.068, 95% confidence interval [CI]: 1.009-1.130, P: 0.024) and positive blood culture (OR: 4.436, 95% CI: 1.044-18.848, P: 0.044) were found to be independent predictors of in-hospital mortality. CONCLUSION: Advanced age, lower ejection fraction, high creatinine, positive blood culture, high systolic pulmonary artery pressure, and septic shock predicted in-hospital death in patients who have undergone emergent or urgent surgery due to infective endocarditis.

The Predictive Role of Small Airway Dysfunction in Postoperative Atrial Fibrillation After Isolated Coronary Artery Bypass Surgery.

OBJECTIVE: Atrial fibrillation is the most common arrhythmia following coronary artery bypass graft surgery. The relationship between impaired lung function and atrial fibrillation has been described previously. We aimed to evaluate the prognostic influence of small airway function on predicting postoperative atrial fibrillation undergoing isolated coronary artery bypass graft surgery (CABG). METHODS: We retrospectively analyzed 283 patients who underwent isolated CABG at our institution between January 2020 and August 2020. The patients were divided into 2 groups according to the development of postoperative atrial fibrillation. Demographic characteristics of the patients were recorded; spirometry was performed for each patient before surgery. Small airway function was determined by forced mid-expiratory flow (forced expiratory flow 25%-75%) values measured by spirometry. Propensity score matching was applied to ensure a balanced distribution of demographic data between the 2 groups. RESULTS: The frequency of postoperative atrial fibrillation was 30.7% in our patient population. After propensity matching, forced expiratory volume in 1 second/forced vital capacity % [80.6 (73.8-87.8) vs. 76.3 (66.7-81.6), P = 0.006] and forced expiratory flow 25%-75% (87.4 ± 14.2 vs. 75.2 ± 15.8, P = 0.001) were significantly lower in postoperative atrial fibrillation group. In multivariate analysis, white blood cell count, left ventricular ejection fraction, cross-clamp time, and forced expiratory flow 25%-75% were found to be independent predictors of postoperative atrial fibrillation development after isolated CABG. In the receiver operating characteristic curve analysis, forced expiratory flow 25%-75% with an optimal threshold value of 81% could detect the presence of postoperative atrial fibrillation with 63.8% sensitivity and 70.1% specificity. CONCLUSION: Our study demonstrated that small airway obstruction, as indicated by forced expiratory flow 25%-75% in spirometry, can be a simple predictive tool for the development of postoperative atrial fibrillation in patients undergoing isolated CABG.

The relation of right ventricular outflow tract measurements with in-hospital clinical outcomes after tricuspid valve surgery.

Right ventricular (RV) function is a determining factor for clinical outcomes in patients undergoing tricuspid valve surgery (TVS). Our aim was to investigate the importance of the function of the right ventricular outflow tract (RVOT), which is an important anatomical region of the RV, in patients underwent TVS. 104 patients who underwent TVS were analyzed retrospectively. Patients with previous cardiac surgery, congenital heart disease, or heart failure were excluded. The parasternal short-axis view at the level of the aortic root was used to measure RVOT dimensions and RVOT fractional shortening (RVOT-FS). The effect of RVOT diameter and function on major adverse cardiac events (MACE) after TVS was investigated. In our study, MACE, consisting of pacemaker implantation, acute kidney injury, postoperative atrial fibrillation and mortality, was developed at 44 (42.3%) patients.We compared the predictive performances of RVOT end-systolic (RVOTs) diameter, RVOT end-diastolic (RVOTd) diameter, RVOT-FS and RV diameters in prediction of MACE. The model including the RVOTs had higher AUC, R2 and likelihood ratio X2 values (0.775, 0.287 and 25.0, respectively) than RVOTd (0.770, 0.279 and 24.2, respectively) and RVOT-FS (0.750, 0.215 and 18.1, respectively). RVOT diameters showed better performance in predicting MACE than RV diameters. Moreover, there was statistically significant association between RVOTs, RVOTd and MACE (p value were 0.014 and 0.027, respectively), while no association between RVOT-FS and MACE (p value was 0.177). In summary, we determined that the RVOT diameters are important predictors for the in-hospital clinical outcomes of patients who underwent TVS.

O Valor Preditivo do Escore CHA2DS2-VASc no Escore Syntax Residual em Pacientes com Infarto do Miocárdio com Supradesnivelamento do Segmento ST / The Predictive Value of CHA2DS2-VASc Score on Residual Syntax Score in Patients With ST Segment Elevation Myocardial Infarction

Resumo Fundamento O escore CHA2DS2-VASc está associado a desfechos clínicos adversos em pacientes com doença cardiovascular. O escore Syntax residual (residual Syntax score — rSS) é uma ferramenta de pontuação que tem valor prognóstico em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Objetivos Este estudo objetivou investigar o valor preditivo do escore CHA2DS2-VASc para o rSS em pacientes com IAMCSST. Métodos Foram avaliados 688 pacientes consecutivos com IAMCSST submetidos à intervenção coronária percutânea. Além do escore CHA2DS2-VASc, variáveis demográficas e clínicas de referência foram analisadas. Os pacientes foram divididos em dois grupos: grupo 1 - indivíduos com rSS até 8 (509 pacientes); grupo 2 - aqueles com rSS acima de 8 (179 pacientes). Valores p<0,05 foram considerados estatisticamente significativos. Resultados O escore CHA2DS2-VASc foi maior no grupo 2 [1 (0-2); 1 (1-3), p<0,001] comparado ao grupo 1. A incidência de hipertensão [151 (29,7%); 73 (40,8%), p=0,006], idade ≥75 anos [18 (3,5%); 21 (11,7%), p<0,001], diabetes mellitus [85 (16,7%); 50 (27,9%), p=0,001] e doença vascular [12 (2,4%); 11 (6,1%), p=0,029] foi maior no grupo 2. Na análise de regressão logística multivariada, o escore CHA2DS2-VASc (odds ratio — OR=1,355; intervalo de confiança de 95% — IC95%=1,171-1,568; p<0,001), idade ≥75 anos [OR=3,218; IC95%=1,645-6,295; p=0,001] e diabetes mellitus [OR=1,670; IC95%=1,091-2,557; p=0,018] foram preditores independentes de rSS elevado. A análise da curva receiver-operating characteristic demonstrou o bom valor preditivo do escore CHA2DS2-VASc para rSS elevado com valor de corte de 1,5 (área sob a curva/area under the curve — AUC= 0,611, IC95%=0,562-0,659, p<0,001). Conclusões O escore CHA2DS2-VASc tem valor preditivo para rSS em pacientes com IAMCSST. Além disso, o escore CHA2DS2-VASc foi um preditor independente de rSS mais alto.

Abstract Background The CHA2DS2-VASc score is associated with adverse clinical outcomes in patients with cardiovascular disease. The residual Syntax score (rSS) is a scoring tool which has prognostic value in patients with ST segment elevation myocardial infarction (STEMI). Objectives Our aim in this study is to investigate the predictive value of the CHA2DS2-VASc score on rSS in STEMI patients. Methods A total of 688 consecutive patients with STEMI undergoing percutaneous coronary intervention were evaluated. Baseline demographic and clinical variables besides the CHA2DS2-VASc score were assessed. The patients were divided into two groups; patients with rSS of 8 or below as group 1 (509 patients) and more than 8 as group 2 (179 patients). A p-value < 0.05 was considered statistically significant. Results The CHA2DS2-VASc score was higher in group 2 [1 (0-2); 1 (1-3), p<0.001] compared to group 1. The incidence of hypertension [151 (29.7%); 73 (40.8%), p=0.006], patients ≥75 years [18 (3.5%); 21 (11.7%), p<0.001], diabetes mellitus [85 (16.7%); 50 (27.9%), p=0.001] and vascular disease [12 (2.4%); 11 (6.1%), p=0.029] were higher in group 2. In multivariate logistic regression analysis, the CHA2DS2-VASc score (OR=1.355; 95%CI=1.171-1.568; p<0.001), age ≥75 years [OR=3.218; 95%CI=1.645-6.295; p=0.001] and diabetes mellitus [OR=1.670; 95%CI=1.091-2.557; p=0.018] were independent predictors of high rSS. The receiver-operating characteristic curve analysis demonstrated that the CHA2DS2-VASc score had good predictive value for high rSS with a cut-off value of 1.5 (area under curve (AUC): 0.611, 95% confidence interval (CI):0.562-0.659, p<0.001). Conclusions The CHA2DS2-VASc score has a predictive value on rSS in patients with STEMI. The CHA2DS2-VASc score was also an independent predictor of higher rSS.

A Novel Marker Indicating Restenosis in Superficial Femoral Artery: C Reactive Protein to Albumin Ratio.

BACKGROUND: In this study, we aimed to investigate the prognostic value of C-reactive protein (CRP) to albumin ratio (CAR) for predicting restenosis in superficial femoral artery (SFA) lesions and its association with subsequent clinical outcomes in patients undergoing endovascular intervention. METHODS: The records of 685 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into 2 groups, based on the CAR values. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed. RESULTS: According to our study, patients with high CAR values had higher rates of restenosis (30.2% vs. 10.3%, P < 0.05) and mortality (31.3% vs. 12.9%, P < 0.05). The rate of lower extremity amputations was also significantly higher in patients with high CAR values compared to those with low CAR values (9.1% vs. 3%, P < 0.05). With respect to Receiver operating characteristic ROC curves of inflammatory markers, the area under the curve (AUC) value of CAR was statistically significant (AUC: 0.659; 95% confidence interval CI: 0.611-0.706; P < 0.01). CONCLUSIONS: Our data showed that CAR is an independent predictor of restenosis and poor clinical outcomes in patients undergoing endovascular intervention.

The role of three dimensional transesophageal echocardiography novel-score in the success of redo percutaneous balloon mitral valvuloplasty.

Mitral valve commissure evaluation is known to be important in the success of percutaneous balloon mitral valvuloplasty (PBMV) and Wilkins score (WS) is used in clinical practice. In our study, we aimed to determine whether WS in redo PBMV is sufficient in the success of procedure and additionally we have evaluated a novel scoring system including three dimensional (3D) transesophageal echocardiography (TEE) of the mitral valve structure before redo PBMV in terms of success of the procedure. Fifty patients who underwent redo PBMV were included in the study. The patients were divided into two groups according to the success of the Redo PBMV procedure which was defined as post-procedural MVA ≥ 1.5 cm2 and post-procedural mitral regurgitation less than moderate by echocardiographic evaluation after PBMV. A novel score based on 3D TEE findings was created by analyzing the images recorded before Redo PBMV and by evaluating the mitral commissure and calcification. The role of traditional WS and novel score in the success of the procedure were investigated. In the study group, 36 patients (72%) had successful redo PBMV procedure. WS was 8 (IQR 7-9) and novel 3D TEE score was found 4 (IQR 3-4) in the whole study group. While no statistically significant relationship was found between WS and procedural success (p = 0.187), a statistically significant relationship was found between novel 3D TEE score and procedural success (p = 0.042). Specifically, the procedural successes rate was > 90% when novel 3D TEE score was < 4. The novel 3D TEE score might be an informative scoring system in the selection of suitable patients for successful redo PBMV, especially in patients who are considered for surgery due to the high WS.

Association Between CRP/Albumin Ratio and Long-Term Mortality in Patients With cHronIc Limb-Threatening Ischemia Undergoing EndovaScular Therapy Below The Knee: The ACHILES-BTK Registry.

BACKGROUND: Chronic limb-threatening ischemia (CLTI), which presents with ischemic rest pain, ulceration, or gangrene, is a complex form of peripheral artery disease that can cause mortality and amputation. C-reactive protein (CRP), an inflammatory marker, indicates vascular inflammation resulting from the cytokine-dependent inflammatory process in the arterial wall, and arterial atherosclerosis resulting from the inflammation. Lower albumin levels are also associated with peripheral artery disease. We investigated the association between CRP/Albumin ratio (CAR) and long-term mortality in patients with CLTI. METHODS: A total of 172 patients who underwent endovascular treatment (EVT) for below the knee (BTK) lesions were enrolled in this study. Patients with acute infection requiring antibiotic therapy, chronic inflammatory disease, end-stage liver disease, malignancy were excluded from the study. Besides, patients with pre-follow-up intervention to the same vascular bed were also excluded from the study. The primary endpoint of the study was all-cause mortality. Patients were divided into 2 groups according to mortality. RESULTS: A total of 70 patients (40.6%) died during 32 ± 21 months of follow-up in the present study. The major amputation rate was 21.5%. The mortality (+) group was older and had higher rates of congestive heart failure, chronic kidney disease, history of stroke, and CRP levels. Moreover, statin and ACE inhibitor/angiotensin receptor blocker (ACE/ARB) use, GFR, and albumin levels were lower in the mortality (+) group. CAR was significantly higher in the mortality (+) group when comparing both groups (3.25 [1.46 - 7.86] vs. 9.75 [4.5 - 17.71], P < 0.001). CAR, congestive heart failure, chronic kidney disease, history of stroke, ACE/ARB, or statin use were independent predictors of all-cause mortality in multivariable Cox regression analysis. CONCLUSIONS: CAR was associated with mortality in CLTI patients undergoing EVT for BTK lesions. CAR may be a simple method to help patient selection, assessment, and intervention strategy for EVT and may improve patient outcomes.

The Association between Tp-e interval, Tp-e/QT, and Tp-e/QTc Ratios and Coronary Artery Disease Spectrum and Syntax Score

Abstract Background Coronary artery disease (CAD) causes electrical heterogeneity on ventricular myocardium and ventricular arrhythmia due to myocardial ischemia linked to ventricular repolarization abnormalities. Objective Our aim is to investigate the impact of increased level of CAD spectrum and severity on ventricular repolarization via Tp-e interval, Tp-e/QT and Tp-e/QTc ratios. Methods 127 patients with normal coronary artery (group 1), 129 patients with stable CAD (group 2) and 121 patients with acute coronary syndrome (group 3) were enrolled. Tp-e interval, Tp-e/QT and Tp-e/QTc ratios were evaluated as well as baseline demographic and clinical parameters. Kruskal-Wallis one-way ANOVA test was used for comparing quantitative variables with abnormal distribution while One-Way ANOVA test was used for comparing the means between groups with normal distribution. Tukey HSD and Welch tests were used for subgroups analyses with normal distribution. Spearman analysis was used to evaluate the correlation between clinical variables and repolarization markers. A p-value < 0.05 was considered statistically significant. Results Tp-e interval [66(50-83), 71(59-82) and 76(64-86); group 1,2 and 3 respectively, p<0.001], Tp-e/QT (0.170.02, 0.180.01 and 0,190.01; group 1,2 and 3 respectively, p<0.001) and Tp-e/QTc (0.150.02, 0.160.02 and 0.170.02; group 1,2 and 3 respectively, p<0.001) ratios were found to be associated with increased level of CAD spectrum. Syntax score was positively correlated with Tp-e interval (r=0.514, p<0.001), Tp-e/QT (r=0.407, p<0.001), and Tp-e/QTc ratios (r=0.240, p<0.001). Conclusion Prolonged Tp-e interval and increased Tp-e/QT and Tp-e/QTc ratios were detected in the presence of CAD and especially in patients with acute ischemic syndromes.

Systemic immune-inflammation index predicts mortality in infective endocarditis.

OBJECTIVES: The aim of our study was to evaluate the usefulness of systemic immune-inflammation index (SII) at admission in predicting in-hospital mortality in patients with infective endocarditis. METHODS: 133 definite IE patients (≥18 years) according to modified Duke criteria, treated in our tertiary care hospital between December 2009 and May 2019, were retrospectively analysed. Symptoms, comorbidities, predisposing valvular diseases, prosthetic valve, device, history of injectable drug use, blood culture results, echocardiography findings, and complications were collected. We calculated the SII as follows: SII = platelet count × neutrophil count/lymphocyte count at admission. RESULTS: The median age of the patients was 56 (40-66) years. Prosthetic valve disease was the most frequent predisposing valve lesion. Staphylococcus species were the most common microorganisms. The most frequent complication was in-hospital mortality (22%) followed by renal failure. Older population, syncope, increased inflammatory markers, high systolic pulmonary artery pressure (PAPs), heart failure, renal failure, and septic shock were associated with high mortality. However age, syncope, hypocalcemia, not going to surgery, and SII were independent predictors of in-hospital mortality. According to receiver operating characteristic curve analysis, the optimal SII cut-off value for predicting mortality was 2314 (area under the curve 0.641; P = 0.019). CONCLUSION: We demonstrated that high SII levels are independently associated with in-hospital mortality. The SII may be a promising prognostic predictor for patients with infective endocarditis.

Effect of lung resection on electrocardiography.

BACKGROUND: Post-operative changes in electrocardiography (ECG) after lung surgery have been investigated in prior researches. We have limited data about benign physiologic changes in ECG after lung surgery, specifically after lung resection. The aim of our study was to investigate relationship in between lung resection with minimally invasive robotic or video-assisted thoracoscopic surgery (VATS) and its effect on ECG after lung resection. METHODS: After exclusion criteria had been applied, a total of 133 patients were enrolled in the present study. Operational information such as amount of resected segment and side of resection was recorded. Lung resections were divided into two groups. One group included surgeries with lung resections <3 segments and other group included surgeries with segmentectomy ≥3 segments. Pre-operative and postoperative (in between 2nd and 3rd months) ECG data of the patients were compared. The location of resected segments as left-sided and right-sided resections were noted to compare the ECG changes for sub-analysis. RESULTS: Among 133 patients, 101 patients were male (75.9%). There was no significant difference between parameters including ventricular rate, P wave, QRS wave and T wave axis in degrees, PR, QRS, QT and QTc durations, Tpe interval, ratio of Tpe interval to QT and QTc interval and fQRSTa. There was significant difference between before and after resection in terms of degree of QRS axis (before resection =37.3 ± 52.7 vs. after resection = 26.2 ± 55.7, P = .026). Sub-analysis regarding to amount of resected segments, there was no significant difference identified in terms of QRS axis in degrees between before and after resection for patients who underwent lung resection <3 segments (p = .885). However, there was significant difference in QRS axis in degrees for patients who underwent lung resection ≥3 segments (before resection = 47.3 ± 57.5 vs. after resection = 23.7 ± 66.2, P = .010). There was significant rightward axial change after left-sided lung resections (before resection =32.0 ± 52.4 vs. after resection = 49.4 ± 47.1, P = .005) and leftward axial change after right-sided lung resection (before resection = 41.7 ± 53.0 vs. after resection = 7.1 ± 55.2, P < .001). CONCLUSION: Understanding and recognition of possible ECG changes are crucial during post-operative follow-up of the patients who underwent lung resection. These changes might be benign changes, which are related to anatomical and geometrical changes within thoracic cavity.

Treatment approach to coronary aneurysms: percutaneous or surgical?

We have recently read with great interest the article by Teng P et al. entitled "Giant right coronary artery aneurysm mimicking a right intra-ventricular mass: a case report". We appreciate the authors for their reports describing the treatment of a giant right coronary aneurysm mimicking a right intra-ventricular mass. On the other hand, we believe that there are some major drawbacks that need to be addressed.

The Prognostic Value of C-reactive Protein to Albumin Ratio in Patients with Isolated Degenerative Aortic Valve Stenosis Undergoing Surgical Aortic Valve Replacement.

OBJECTIVE: To evaluate the prognostic value of C-reactive protein to albumin ratio (CAR) in patients with severe aortic valve stenosis undergoing surgical aortic valve replacement (AVR). METHODS: Four hundred seventy-six patients with severe degenerative aortic stenosis who underwent successful isolated surgical AVR were enrolled. Hospitalization due to heart failure, surgical aortic reoperation, paravalvular leakage rates, and long-term mortality were evaluated in the whole study group. The participants were divided into two groups, as 443 patients without mortality (group 1) and 33 patients with mortality (group 2) during the follow-up time. RESULTS: CAR was lower in patients without mortality than in those with mortality during the follow-up time (0.84 [0.03-23.43] vs. 2.50 [0.22-26.55], respectively, P<0.001). Age (odds ratio [OR]: 1.062, confidence interval [CI]: 1.012-1.114, P=0.014), CAR (OR: 1.221, CI: 1.125-1.325, P<0.001), ejection fraction (OR: 0.956, CI: 0.916-0.998, P=0.042), and valve type (OR: 2.634, CI: 1.045-6.638, P=0.040) were also found to be independent predictors of long-term mortality. Additionally, rehospitalization (0.86 [0.03-26.55] vs. 1.6 [0.17-24.05], P=0.006), aortic reoperation (0.87 [0.03-26.55] vs. 1.6 [0.20-23.43], P=0.016), and moderate to severe aortic paravalvular leakage (0.86 [0.03-26.55] vs. 1.86 [0.21-19.50], P=0.023) ratios were associated with higher CAR. CONCLUSION: It was firstly described that CAR was strongly related with increased mortality rates in patients with isolated severe aortic stenosis after surgical AVR. Additionally, rehospitalization, risk of paravalvular leakage, and aortic reoperation rates were higher in patients with increased CAR than in those without it.

Conclusion: It was firstly described that CAR was strongly related with increased mortality rates in patients with isolated severe aortic stenosis after surgical AVR. Additionally, rehospitalization, risk of paravalvular leakage, and aortic reoperation rates were higher in patients with increased CAR than in those without it.

Multimodality imaging of an asymptomatic giant right atrial appendage aneurysm.

Right atrial appendage (RAA) aneurysm is a rare congenital cardiac abnormality thought to be caused by dysplasia of the muscular wall of the RA and RAA. Structural, contractile, or electrical atrial changes are associated with the onset and progression of atrial fibrillation. The RAA aneurysm can have various symptoms, such as thromboembolic complications. Diagnosis of RAA aneurysm greatly depends on imaging modalities, among which echocardiography is the most widely used one. Echocardiography is very effective in discovering the aneurysm, distinguishing it from other abnormalities such as pericardial cysts, Ebstein's anomaly and cor triatriatum, and detecting intracardiac thrombosis or blood flow limitations. Cardiac magnetic resonance imaging and computed tomography are important complementary examinations. They may provide more details on the neighboring structures of the aneurysm, especially when echocardiographic images are suboptimal.

Characterization, epidemiological profile and risk factors for clinical outcome of infective endocarditis from a tertiary care centre in Turkey.

Background: We aimed to investigate the clinical, laboratory, microbiological characteristics of IE in a single tertiary care centre in Turkey and to identify the factors associated with in-hospital mortality. Methods: A total of 155 consecutive adult patients (≥18 years) admitted to our single tertiary care hospital between 2009 and 2019 with definite infective endocarditis were retrospectively included in the study. Results: The mean age of the patients was 58 years. Among 155 endocarditis episodes, 60% involved prosthetic valves, 35.5% had native valve endocarditis (NVE) and 4.5% were device related. Prosthetic valve disease was the most frequent predisposing valve lesion followed by degenerative valvular disease. Vegetations were detected in 103 (66.5%) patients by transthoracic echocardiography and in 145 (93%) patients by transoesophageal echocardiography. The most commonly affected valve was the mitral valve in 84 (54.2%) patients, followed by 67 (43.2%) aortic valve. Staphylococci were the most frequent causative microorganisms isolated in both NVE (31.8%), prosthetic valve endocarditis (38.9%) and device related IE cases. At least one complication was present in 70 patients (45.2%). One hundred and eight patients underwent surgical therapy (69.7%). Age, syncope, heart failure, perforation, septic shock, renal failure, high red cell distribution width, atrial fibrillation, hypocalcaemia, pulmonary hypertension were associated with high mortality. Conclusions: We identified a 10-year presentation of IE in a referral centre in Turkey. Likely other series, we observed more staphylococcus endocarditis with the aging of the population. Surgery was associated with higher in-hospital survival. Age, syncope, perforation, septic shock were independent predictors of mortality.

Is there a gender gap in secondary prevention of coronary artery disease in Turkey?

OBJECTIVE: It has been reported that women receive fewer preventive recommendations regarding pharmacological treatment, lifestyle modifications, and cardiac rehabilitation compared with men who have a similar risk profile. This study was an investigation of the impact of gender on cardiovascular risk profile and secondary prevention measures for coronary artery disease (CAD) in the Turkish population. METHODS: Statistical analyses were based on the European Action on Secondary and Primary Prevention through Intervention to Reduce Events (EUROASPIRE)-IV cross-sectional survey data obtained from 17 centers in Turkey. Male and female patients, aged 18 to 80 years, who were hospitalized for a first or recurrent coronary event (coronary artery bypass graft, percutaneous coronary intervention, acute myocardial infarction, or acute myocardial ischemia) were eligible. RESULTS: A total of 88 (19.7%) females and 358 males (80.3%) were included. At the time of the index event, the females were significantly older (p=0.003) and had received less formal education (p<0.001). Non-smoking status (p<0.001) and higher levels of depression and anxiety (both p<0.001) were more common in the female patients. At the time of the interview, conducted between 6 and 36 months after the index event, central obesity (p<0.001) and obesity (p=0.004) were significantly more common in females. LDL-C, HDL-C or HbA1c levels did not differ significantly between genders. The fasting blood glucose level was significantly higher (p=0.003) and hypertension was more common in females (p=0.001). There was no significant difference in an increase in physical activity or weight loss after the index event between genders, and there was no significant difference between genders regarding continuity of antiplatelet, statin, beta blocker or ACEi/ARB II receptor blocker usage (p>0.05). CONCLUSION: Achievement of ideal body weight, fasting blood glucose and blood pressure targets was lower in women despite similar reported medication use. This highlights the importance of the implementation of lifestyle measures and adherence to medications in women.

Adropin and Irisin in Patients with Cardiac Cachexia.

BACKGROUND: Cardiac cachexia is an important predictive factor of the reduction in survival of patients with heart failure with reduced ejection fraction. OBJECTIVES: The aims of the present study were to evaluate adropin and irisin levels in cachectic and non-cachectic subjects and the relationships between the levels of these proteins and clinical and laboratory parameters in patients with HFrEF. METHODS: The clinical records of patients who were admitted to the cardiology outpatient clinic for heart failure with reduced ejection fraction were screened. Cachectic patients were identified and assigned to the study group (n = 44, mean age, 65.4 ± 11.2 y; 61.4% men). Heart failure with reduced ejection fraction patients without weight loss were enrolled as the control group (n = 42, mean age, 61.0 ± 16.5 y; 64.3% men). The serum adropin and irisin levels of all patients were measured. A p-value < 0.05 was considered significant. RESULTS: Serum adropin and irisin levels were significantly higher in the cachexia group than in the controls (Adropin (ng/L); 286.1 (231.3-404.0) vs 213.7 (203.1-251.3); p < 0.001, Irisin (µg/mL); 2.6 (2.2-4.4) vs 2.1 (1.8-2.4); p = 0.001). Serum adropin and irisin levels were positively correlated with brain natriuretic peptide (BNP) levels and New York Heart Association (NYHA) class and negatively correlated with body mass index (BMI) and serum albumin levels (all p values: < 0.001). In a multivariate analysis, adropin was the only independent predictor of cachexia in the heart failure with reduced ejection fraction patients (OR: 1.021; 95% CI: 1.004-1.038; p = 0.017). CONCLUSIONS: The results suggest that adropin and irisin may be novel markers of cardiac cachexia in heart failure with reduced ejection fraction patients. Adropin and irisin are related with the severity of heart failure.

Resumo Fundamento: A caquexia cardíaca é um importante preditor de redução de sobrevida em pacientes com insuficiência cardíaca com fração de ejeção reduzida (ICFER). O objetivo deste estudo foi avaliar os níveis de adropina e irisina em pacientes com ICFER caquéticos e não caquéticos, assim como a relação entre os níveis dessas proteínas e os parâmetros clínicos e laboratoriais nesses pacientes. Objetivos: Os objetivos do presente estudo foram avaliar os níveis de adropina e irisina em indivíduos caquéticos e não caquéticos e as relações entre os níveis dessas proteínas e os parâmetros clínicos e laboratoriais em pacientes com ICFEN. Métodos: Os prontuários de pacientes atendidos no ambulatório de cardiologia para ICFER foram triados. Aqueles com ICFER caquéticos foram identificados e constituíram o grupo de estudo (n = 44; idade média, 65,4 ± 11,2 anos; 61,4% de homens). Aqueles com ICFER e sem perda de peso foram arrolados como grupo controle (n = 42; idade média, 61,0 ± 16,5 anos; 64,3% de homens). Os níveis séricos de adropina e irisina de todos os pacientes foram medidos. Considerou-se significativo um p-valor < 0,05. Resultados: Os níveis séricos de adropina e irisina foram significativamente mais altos nos pacientes caquéticos do que nos controles [adropina (ng/l): 286,1 (231,3-404,0) vs 213,7 (203,1-251,3); p < 0,001; irisina (µg/ml): 2,6 (2,2-4,4) vs 2,1 (1,8-2,4); p = 0,001]. Os níveis séricos de adropina e irisina correlacionaram-se positivamente com os níveis de peptídeo natriurético cerebral (BNP) e a classe funcional da New York Heart Association (NYHA), e negativamente com o índice de massa corporal (IMC) e os níveis séricos de albumina (todos os p-valores: < 0,001). Na análise multivariada, a adropina foi o único preditor independente de caquexia nos pacientes com ICFER (OR: 1,021; IC 95%: 1,004−1,038; p = 0,017). Conclusões: Os resultados sugerem que a adropina e a irisina possam ser novos marcadores de caquexia cardíaca em pacientes com ICFER. Adropina e irisina estão relacionadas com a gravidade da insuficiência cardíaca.
