Abstract
PURPOSE To evaluate the effect of adjuvant Mitomycin C (MMC) use on the anatomical and functional success of vitreoretinal surgery (VRS) in severe diabetic tractional retinal detachment (dTRD) patients. METHODS A retrospective analysis of consecutive patients undergoing VRS due to severe dTRD was conducted. Patients were categorized into those who received 20 µg/0.1 mL MMC via MMC sandwich method (Group 1) and those who did not (Group 2). Demographics, surgical characteristics, visual outcomes, and complications that may related to MMC were analyzed. RESULTS A total of 25 eyes were included, 13 in Group 1 and 12 in Group 2. No statistical difference was observed in baseline characteristics between the groups. The mean best-corrected visual acuity was 1.90 ± 0.43 logMAR and 1.93 ± 0.41 logMAR preoperatively and 1.60 ± 0.78 logMAR and 1.56 ± 0.78 logMAR postoperatively in Groups 1 and 2, respectively (p = 0.154). The postoperative mean intraocular pressure was 16.23 ± 2.55 mmHg and 13.08 ± 4.94 mmHg in Groups 1 and 2, respectively (p = 0.225). The rate of re-surgery was significantly lower in Group 1 (0% vs. 41.7% in Group 2, p = 0.015). Retina was attached in all patients at the last visit. No MMC-related complication was recorded. CONCLUSION Intraoperative adjuvant MMC application for severe dTRD significantly reduces re-surgery rates with good anatomical and functional outcomes safely.

Abstract
INTRODUCTION Active-fixation leads have been associated with higher incidence of cardiac perforation. Large series specifically evaluating radiographic predictors of right ventricular (RV) lead perforation are lacking. METHODS We conducted a retrospective observational study including 1691 consecutive patients implanted with an active fixation pacing and defibrillator lead at our institution between January 2015 and January 2021. Fourteen patients who had clinically relevant RV perforation caused by pacemaker and implantable cardioverter-defibrillator leads were included in the study. RESULTS Univariate and multivariate analyses were used to identify predictors of RV perforation. In multivariate analysis, lead slack score (odds ratio [OR]: 3.694, 95% confidence interval [CI]: 1.066-12.807; p = .039), change in lead slack height (OR: 1.218, 95% CI: 1.011-1.467; p = .038) and width (OR: 1.253, 95% CI: 1.120-1.402; p = .001), left ventricular ejection fraction (OR: 0.995, 95% CI: 0.910-1.088; p = .032) were independent predictors of RV perforation. CONCLUSION Fluoroscopic predictors of RV perforation associated with RV lead can be easily determined during implantation. Identification of these predictors may prevent the sequelae of RV perforation associated with active-fixation leads.

Abstract
Introduction The correlation between non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease is well established. Aim The objective of this study was to assess the short-term associations of the non-alcoholic fatty liver disease fibrosis score (NFS) with various outcomes, including mortality, severe coronary artery disease, myocardial infarction, and the need for coronary angiography, among patients who underwent coronary computed tomographic angiography (CCTA). Material and methods In this study, we assessed 499 patients who underwent 640-slice CCTA and evaluated their liver fibrosis using the NFS. The NFS takes into account factors such as age, body mass index, impaired fasting glycemia or diabetes mellitus, aspartate aminotransferase/alanine aminotransferase ratio, platelets, and albumin. Our primary focus was myocardial infarction, the need for coronary angiography, and death. Additionally, we examined the association between NFS and severe coronary artery disease. Results Patients with a higher NFS had a greater number of coronary angiography procedures and higher Agatston score (p < 0.001), with NFS and Agatston score emerging as independent predictors of severe coronary artery disease and the primary endpoint. An NFS value above -0.92 could predict the primary endpoint with 61% sensitivity and 63% specificity, while an NFS value above -0.88 could predict severe coronary artery disease with 62% sensitivity and 65% specificity. To analyze primary endpoints, the Kaplan-Meier method was used for survival analysis, with NFS groups compared using the log-rank test. During the follow-up period, patients with higher NFS were exposed to primary outcomes at an earlier period (p = 0.009). Conclusions NFS is an effective predictor of major cardiovascular events such as death, myocardial infarction, severe coronary artery disease, and the need for coronary angiography. These findings underscore the importance of NFS as a valuable tool for risk assessment and early intervention in patients with suspected or confirmed coronary artery disease.

Abstract
OBJECTIVE: It is known that providing recanalization alone in large vessel occlusions is not sufficient to provide a good 90-day clinical outcome. It is advocated that neuroprotection should be increased before endovascular treatment and that the penumbra should be protected from reperfusion damage after recanalization. However, the effects of blood gas parameters before and after mechanical thrombectomy on clinical outcomes are not clear. The objective of this study is to assess the effectiveness of serial blood gas measures in accurately predicting futile recanalization at an early stage. PATIENTS AND METHODS: This study is a multicenter inquiry that collected data in a prospective manner and analyzed it retrospectively. Patients with a 2b-3 thrombolysis in cerebral infarction (TICI) score after mechanical thrombectomy for recanalization were consecutively analyzed from July 2022 to March 2023. Arterial blood gas parameters, including pH, oxygen saturation (SaO2), partial carbon dioxide pressure (PaCO2), partial oxygen pressure (PaO2), lactate, and bicarbonate (HCO3), were measured at four time points: before mechanical thrombectomy treatment (preoperative), immediately after recanalization (postoperative 1st), during the 3rd hour (postoperative 3rd), and at the 5th hour (postoperative 5th). The patients were categorized into groups based on their modified Rankin Scale (mRS) scores. RESULTS: The study included 136 patients with an average age of 69.71±11.22. The postoperative 1st-hour SaO2 values were lower in the mRS 3-6 group (p=0.038). The postoperative pH and lactate mean were greater in the mRS 3-6 group than in the 0-2 group (p=0.038 and 0.018, respectively). In logistic regression, a unit rise in lactate increased poor functional outcomes 1,632 times (p=0.024). Early neurological recovery was associated with decreased postoperative 3rd-hour lactate (p=0.014). The mean postoperative PaO2 (average of 1, 2, 3 PaO2) was higher in those with symptomatic cerebral bleeding (p=0.044). CONCLUSIONS: Monitoring lactate and pH levels in AIS patients who have had mechanical recanalization can be utilized to predict mortality and morbidity, especially in the first five hours after the procedure.

Abstract
BACKGROUND There are various changes in cardiac physiology in athletes compared to the normal population. These physiological changes may differ according to the exercise content. The aim of this study was to compare the effects of different exercise methods on the heart. METHODS A total of 122 male athletes from various sports were evaluated. Depending on the sorts of sports, these participants were split into aerobic, mixed, and resistance groups. Each athlete had to meet the inclusion criteria of having participated in the present sport for at least a year and having trained for at least 600 minutes per week over the previous three months. Transthoracic echocardiography was used to investigate the effects of different exercise types. RESULTS The aerobic group's heart rate and ejection fraction were found to be lower than those of the resistance and mixed groups (F(2.105)=23.487, P=0.001). The end-diastolic thicknesses of the interventricular septum (8.7 SD 0.8 vs. 10.0 SD 0.7), interventricular septum (11.3 SD 0.9 vs. 13.0 SD 0.9), left ventricular posterior wall (8.6 SD 0.7 vs. 9.9 SD 0.8), and interventricular septum (11.1 SD 0.9 vs. 13.3 SD 0.9) were all found to be lower in the aerobic group than in the resistance group (P=0.0001). The effect of resistance exercise on heart rate was not observed as clearly as other groups. CONCLUSIONS Resistance exercise has a more dominant effect on ventricular thickness than aerobic exercise. In mixed exercise groups, this increase in thickness is similar to resistance exercise. The content of the training should be considered in the evaluation of the athlete's heart. Identifying the subgroups of the athlete's heart will be useful in the differentiation of pathologies and also in the follow-up of the athletes.

Abstract
PURPOSE This study aims to investigate surgical outcomes of eyes with severe anterior persistent fetal vasculature (PFV) and the role of associated anatomical anomalies on prognosis. METHODS This is a retrospective, comparative case series of 32 eyes of 31 patients who underwent vitreoretinal surgery for severe anterior PFV, defined as fibrovascular tissue totally covering the back of cataractous lens. Based on the degree of anterior retinal elongations, cases were classified as follows: group 1, eyes with well-developed pars plana and minor/no abnormalities (n = 11, 34%); group 2, eyes with partially developed pars plana and broad-based elongations (n = 9, 28%); and group 3, eyes with no visible pars plana and fibrovascular membrane having 360° continuity with peripheral retina (n = 12, 38%). Complications and functional and anatomical outcomes were investigated. RESULTS The median surgical age was 2 (1-12) months. The median follow-up was 26 (6-120) months. Seventy-three percent in group 1 achieved finger counting or better vision with a single surgery and without any pupillary/retinal complication. Groups 2 and 3 required 2.1 ± 0.9 and 2.6 ± 1.2 surgeries on average. Pupillary obliteration and RD occurred in 33% and 22% in group 2 and 58% and 67% in group 3. Retina remained attached after silicone oil removal in 89% of group 2 and 25% of group 3. Phthisis developed in 50% in group 3. CONCLUSION Peripheral retinal anomalies are common in severe anterior PFV and have a major impact on prognosis. Prognosis is favorable in cases with mild-to-moderate anomalies with appropriate management of possible retinal tears. In eyes with 360° retinal elongations, severe fibrous proliferation and eventual eye loss are common.

Abstract
BACKGROUND Extraction of the implantable cardioverter-defibrillator (ICD) leads could be a difficult procedure due to fibrous tissue around the lead and anatomical variations. In this report, we present our experience in the radiographic predictors of failure of simple manual traction (SMT) in patients with dual-coil ICD requiring lead extraction (LE). METHODS Between January 2017 and February 2021, 103 leads were removed in 65 consecutive patients; 65 (63.1%) were dual-coil ICD leads, 22 (21.4%) were atrial, and 16 (15.5%) were coronary sinus leads. Patient-based and procedural data were collected and analyzed retrospectively. Clinical and procedural characteristics were compared and radiographic predictors of failure of SMT of ICD leads were assessed. Projected anteroposterior (AP) lead tortuosity was measured and lead slack score was estimated on chest X-ray (CXR). RESULTS Simple manual traction failed in 27 (42%) of the ICD leads. Ottawa slack score (odds ratio [OR] 2.368, 95% CI [1.261-4.447]; P = 0.007), AP lead tortuosity > 1.10 (OR 7.477, 95% CI [1.718-35.542]; P = 0.007), and number of previous interventions (OR 6.016, 95% CI [1.184-30.557]; P < 0.030) were found to be independently related to the failure of SMT. Receiver-operator characteristic curve analysis yielded an AP lead tortuosity cutoff value of > 1.10 for predicting the failure of SMT. The area under the curve was 0.744; the 95% confidence interval (CI) was 0.617 to 0.871 (P = 0.001), with a sensitivity of 63% and a specificity of 73%. CONCLUSION Simple manual traction success in our study varied based on radiographic lead-related parameters. Before planning the procedure, increased AP lead tortuosity in vasculature and higher lead slack score can be easily determined on CXR and may be associated with more fibrous adherences, the complexity of the LE, and failure of SMT.

Abstract
OBJECTIVE Isolated ostial diagonal stenoses are very rare lesions in which percutaneous intervention could cause significant vessel compromise, and the long-term results have been reported in a few studies. This study sought the characteristics and long-term follow-up of the patients with isolated osteal diagonal stenosis regarding percutaneous coronary intervention and presence of angina. METHODS The study was an observational retrospective study conducted between January 2014 and December 2020. A total of 9769 patients who underwent coronary angiography were analyzed, and 87 patients had isolated diagonal stenosis. The patients were evaluated according to treatment modality and angina severity in long-term pattern. RESULTS Median follow-up time was 36 months. A total of 54 (83.1%) patients were followed up with only medical treatment, and 11 (16.9%) patients underwent revascularization in addition to medical treatment. The degree of stenosis of the diagonal artery was significantly higher in the percutaneous coronary intervention group than medical group (P = 0.002) and the patients with wider reference diameter of diagonal artery complaint of more angina (P = 0.007). Class I angina was significantly higher in percutaneous coronary intervention group than medical and the patients with no angina were significantly higher in medical group than percutaneous coronary intervention group. CONCLUSION Percutaneous coronary intervention was mainly performed for diagonal arteries with a higher degree of stenosis; however, the patients who underwent percutaneous coronary intervention had angina more than 50% rates. Furthermore, the patients with ongoing angina had a larger diameter of the diagonal artery regardless of the type of treatment.

Abstract
Low-load resistance training combined with blood flow restriction (BFR) is known to result in muscle hypertrophy and strength similar to that observed with higher loads. However, the effects of resistance training with BFR on cardiac structure and cardiac function remain largely unknown. Therefore, the purpose of this randomized study was to compare the effects of conventional high-load resistance training (HL-RT) with the effects of low-load resistance training with BFR (LL-BFR) on muscle strength and left ventricular function. Sixteen young swimmers (mean ± standard deviation: age = 19.7 ± 1.6 years, body mass = 78.9 ± 9.7 kg, body height = 180.8 ± 5.8 cm) were randomly allocated to a conventional HL-RT group (n = 8) or a LL-BFR group (n = 8) with a pressure band (200 mmHg) placed on both thighs of participants for 4 weeks (3 days•week-1). Outcome measures were taken at baseline and after 4 weeks of training, and included body composition, one-repetition maximum (1RM) back squat, and echocardiography measures. The 1RM back squat significantly improved (partial eta squared (Ƞ2) = 0.365; p = 0.013) in HL-RT (mean difference (Δ) = 6.6 kg; [95% confidence interval (CI) -7.09 to 20.27]) and LL-BFR groups (Δ = 14.7 kg; [95% CI 3.39 to 26.10]), with no main effect of group or group × time interaction (p > 0.05). Interventricular septum end-systolic thickness showed a slight but statistically significant increase in LL-BFR and HL-RT groups (Ƞ2 = 0.253; p = 0.047), yet there was no main effect of group or group × time interaction (p > 0.05). There were no statistically significant changes (p > 0.05) in other cardiac structure or function parameters (e.g., left ventricular (LV) mass, LV cardiac output, LV ejection fraction, LV stroke volume) after the training programs. Results suggest that 4 weeks of HL-RT and LL-BFR improve muscle strength similarly with limited effects on left ventricular function in young swimmers.

Abstract
Cardiac resynchronization therapy (CRT) device procedures have their own complications in addition to the complications associated with standard pacemaker implantations. This study aimed to analyze the predictors of the right bundle branch injury resulting in complete heart block (CHB) during right ventricular (RV) lead implantation in patients who underwent CRT with defibrillator. We conducted an observational study of consecutive 790 patients who underwent CRT with defibrillator device implantation at our institution from 2010 to 2022. Relevant clinical information and complete data regarding the echocardiographic data, implantation procedure, and clinical follow-up were collected into a computerized database. A total of 29 patients (3.7%) had CHB during RV lead implantation. In multivariate analysis, left axis deviation (odds ratio [OR] 2.408, 95% confidence interval [CI] 1.025 to 5.658, p = 0.044), QRS width (OR 1.022, 95% CI 1.001 to 1.043, p = 0.035) and QRS alternans (OR 4.214, 95% CI 1.788 to 9.930, p = 0.001) were found independently related to right bundle branch injury resulting in CHB development during RV lead implantation. In conclusion, left axis deviation, QRS width, and QRS alternans were associated with a higher rate of CHB, and these findings provide insight into optimal and safe CRT device implantation strategies based on preprocedural characteristics.

Abstract
BACKGROUND/OBJECTIVES To determine the role of vitreoretinal surgery (VRS) for two different forms of posterior persistent fetal vasculature syndrome (PFVS); with tent-shaped tractional retinal detachment (TRD) and closed funnel-shaped TRD. SUBJECTS/METHODS Retrospective, single surgeon, consecutive case series of 52 eyes of 44 patients with posterior PFVS who underwent VRS. Cases were divided into "tent-shaped TRD" and "funnel-shaped TRD" groups based on the preoperative TRD configuration. Associated anomalies, functional and anatomical outcomes were evaluated. The cosmetic appearance was defined as poor if there was phthisis bulbi, gross buphthalmos, or corneal opacification; acceptable if there was apparent leukocoria; and excellent if none were noted at the last follow-up. RESULTS Thirty eyes of 29 patients presented with tent-shaped TRD; 70% of which obtained counting fingers or better vision and 90% showed significant reversal of tenting achieving retinal reattachment. The cosmetic appearance was excellent in 87%. Two eyes (7%) became phthisic. Twenty-two eyes of 15 patients presented with funnel-shaped TRD and leukocoria; 45% achieved LP vision and 70% of patients with bilateral pathology had LP in at least one eye. The cosmetic appearance was acceptable to excellent in 73%. Three eyes (14%) became phthisic, one (5%) of which required enucleation. The median follow-up time was 16 (6-71) months. CONCLUSIONS VRS often provides functional vision and anatomy in posterior PFVS with tent-shaped TRD morphology. In the funnel-shaped TRD morphology, where no treatment has historically been recommended, surgery may be considered with an aim of restoring light perception and globe preservation, particularly in bilateral cases.

Abstract
Bicuspid aortic valve is the most common congenital cause for the development of aortic valve calcification and stenosis. Calcification cause valvular stenosis or valvular insufficiency due to coaptation failure. We report a unique case of calcification of bicuspid valve was extending to left ventricular outflow tract and attached to interventricular septum which caused subvalvular stenosis.

Abstract
BACKGROUND Cardiac resynchronization therapy (CRT) is an effective option in the treatment of patients with heart failure and wide QRS. Non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS) has been shown to predict cardiac events in several patient populations. However, the relationship between NFS and response to CRT has not been investigated. The aim of the study was to investigate the predictive role of NFS in the assessment of response after CRT. METHODS Three hundred thirty-six patients with heart failure undergoing CRT were prospectively studied. Liver fibrosis were assessed according to the non-alcoholic fatty liver disease fibrosis score (NFS), which includes age, body mass index, impaired fasting glycemia or diabetes mellitus, aspartate aminotransferase /alanine aminotransferase ratio, platelets, and albumin. Echocardiographic response to CRT was defined by a ≥15% reduction in left ventricular end-systolic volume at six months at follow-up. RESULTS Two hundred thirty-eight patients (71%) had CRT response after 6 months of follow-up. Receiver-operator characteristic curve analysis showed NFS cutoff value of < -1.12 for predicting CRT response with a sensitivity of 70.4% and a specificity of 52.9%. The patients were also divided into four groups according to the quartiles of NFS. The proportion of response to CRT was increased with lower level of NFS value. Multivariate logistic regression analysis demonstrated the NFS score < -1.12 and LVIDs were independent predictors of the CRT response. In the second model of analysis which included NFS, quartiles demonstrated that fourth NFS quartile and LVIDs were independent predictors of CRT response. CONCLUSION Liver fibrosis assessed by NFS can provide valuable information to predict reverse remodeling in patients undergoing CRT. The present study supports monitoring of NFS to improve preoperative risk stratification of these patients.

Abstract
Coronary artery perforations and dissections, associated with cardiac tamponade or acute vessel closure, are life-threatening complications of percutaneous coronary intervention. In some cases, subepicardial hematomas could occur and compress the vessel. A 59-year-old woman was admitted to our hospital with chest pain and was diagnosed with non–ST-elevation myocardial infarction. Coronary angiography showed the total occlusion of the diagonal artery. During the intervention, left main coronary artery dissection and intramural hematoma occurred as coronary complications. The left main coronary artery was stented; however, the extension of the hematoma through the ostium of the left anterior descending artery caused further complications. The patient underwent an urgent coronary artery bypass graft surgery and was discharged on the seventh postoperative day.

Abstract
BACKGROUND Intraprocedural coronary angiography (CA) is recommended in patients undergoing ablation in aortic cusps to assess the relation of catheter tip and coronary ostia. In this report, we aimed to compare selective coronary angiography (SCA) through the contact force (CF)-sensing radiofrequency catheter with conventional coronary angiography (CCA) to guide ablation of premature ventricular contractions (PVC). METHODS This was a retrospective observational cohort study of prospectively collected data of 87 consecutive patients undergoing PVC ablation at a single institution between February 2016 and June 2021. Forty-six patients (53%) underwent SCA and forty-one patients (47%) underwent CCA. Data were consecutively collected case-by-case and entered into a computerized database. Procedural characteristics, complications, and clinical outcomes were compared between the SCA and CCA groups. RESULTS Successful ablation was achieved in seventy-seven (89%) patients. Total procedure and fluoroscopy time and radiation dose were significantly lower in SCA group (93 ± 22 min vs 102 ± 20 min, p = 0.042; 12 ± 3 min vs 14 ± 4 min, p = 0.030; 3292 ± 1221 μGy m2 vs 3880 ± 1229 μGy m2, p = 0.028, respectively). Median ambulation time was significantly longer in CCA group (6.8 ± 1 h vs 17.8 ± 1.8 h, p = 0.006). CONCLUSIONS Selective coronary angiography through the CF-sensing ablation catheter to assess the relation between the ablation site and the coronary ostia is feasible and safe. This technique precludes the requirement of an additional arterial access and decreases the total procedure and fluoroscopy time and radiation dose.

Abstract
Introduction Intraprocedural coronary angiography is recommeded in patients undergoing ablation in aortic cusps to assess the relation of catheter tip and coronary ostia. In this report, we present our experience in selective coronary angiography through the radiofrequency catheter during premature ventricular contraction (PVC) ablation. Methods and results We prospectively recruited 43 consecutive patients who underwent PVC ablation in the aortic cusps between March 2018 and April 2021. We performed coronary angiography through the contact force (CF)-sensing ablation catheter at the ablation site. Successful ablation was achieved in 38 (88%) of patients. No technical problems occurred after the contrast injection and ablation parameters were within the normal values, without any change of impedance and CF-sensing values and neither electrogram signal quality after contrast injection. No complications occurred during the procedure, hospital stay, and during one-year follow-up (15.3 ± 3.1 months). Conclusion Selective coronary angiography through the CF-sensing ablation catheter to assess the relation between the ablation site and the coronary ostia is feasible and no minor or major complications occurred in our experience.

Abstract
BACKGROUND AND AIMS The Friedewald equation (LDL-Cf) is known to produce inaccurate estimations of low-density lipoprotein cholesterol (LDL-C) when triglycerides are high (>400 mg/dL) or LDL-C is low (<70 mg/dL). The Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) equations were developed to overcome these limitations, but few data are available to assess whether these equations offer incremental usefulness over LDL-Cf. Our aim was to understand whether there was any incremental usefulness of novel equations on decisions regarding patient management. METHODS Four thousand one hundred and ninety-six cardiology patients who were included in a multicentre registry database were analysed. Each patient was assigned to a cardiovascular risk class using the SCORE (Systematic COronary Risk Evaluation) algorithm, and relevant European guidelines were used to assess LDL-C targets. RESULTS Compared with LDL-Cmh and LDL-Cs, LDL-Cf was able to correctly identify 96.9%-98.08% of patients as within or outside the LDL-C target, respectively, and 1.95%-2.8% of patients were falsely identified as being within the LDL-C target. Kappa coefficients for agreement between LDL-Cf vs LDL-Cmh and LDL-Cf vs LDL-Cs were 0.868 and 0.918 (P < .001). For patients not on cholesterol-lowering drugs, the decision to initiate treatment would be different in 1.2%-1.8% of cases if LDL-Cs or LDL-Cmh were used, respectively. For those already on cholesterol-lowering drugs, decisions regarding treatment intensification would be different in 1.5%-2.4% of cases if LDL-Cs or LDL-Cmh were used. CONCLUSIONS In most cardiology outpatients, the Friedewald equation has excellent agreement with the novel Martin/Hopkins and Sampson equations, and treatment decisions should not change in most patients.

Abstract
Introduction Pulmonary arterial hypertension and human immunodeficiency virus (HIV) infection is a well-known association. Pulmonary pulse transit time (pPTT) is a recent echocardiographic marker that might be used for evaluation of pulmonary arterial stiffness (PAS) in patients with HIV infection. We aimed to investigate whether pPTT elevated in patients with HIV infection compared to healthy controls and its association with echocardiographic indices of right ventricular functions. Materials and Methods Fifty HIV (+) patients from infectious disease outpatient clinics and fifty age- and sex-matched HIV (-) healthy volunteers were enrolled in this study. pPTT was measured from pulmonary vein flow velocity as the time interval between the R-wave in the electrocardiography and corresponding peak late systolic was then calculated as the mean from two separate pw-Doppler measurements. Results pPTT, tricuspid annular peak systolic excursion (TAPSE) and right ventricle fractional area change (FAC) were significantly lower in patients with HIV than control patients (177.1 ± 34.9 vs. 215.7 ± 35.7 msn, P < 0.001; 2.33 ± 0.28 vs. 2.19 ± 0.22, P = 0.039; 45 [4.25] vs. 41.1 [4.0], P = 0.032, respectively). pPTT was positively correlated with FAC, TAPSE and cluster of differentiation 4 count (r = 0.210; P = 0.036, r = 0.256; P = 0.041, r = 0.304; P = 0.044, respectively). Conclusion Our study showed that pPTT, TAPSE, and right ventricle FAC levels were lower in patients with HIV infection. pPTT is an important predictor in patients with HIV expected to develop pulmonary vascular pathology.

Abstract
AD is the highly severe part of the dementia spectrum and impairs cognitive abilities of individuals, bringing economic, societal and psychological burdens beyond the diseased. A promising approach in AD research is the analysis of structural and functional brain connectomes, i.e., sNETs and fNETs, respectively. We propose to use tensor representation (B-tensor) of uni-modal and multi-modal brain connectomes to define a low-dimensional space via tensor factorization. We show on a cohort of 47 subjects, spanning the spectrum of dementia, that diagnosis with an accuracy of 77% to 100% is achievable in a 5D connectome space using different structural and functional connectome constructions in a uni-modal and multi-modal fashion. We further show that multi-modal tensor factorization improves the results suggesting complementary information in structure and function. A neurological assessment of the connectivity patterns identified largely agrees with prior knowledge, yet also suggests new associations that may play a role in the disease progress.

Friedewald equation (LDL-Cf) is known to produce inaccurate estimations of low-density lipoprotein cholesterol (LDL-C) when triglycerides are high (>400 mg/dl) or LDL-C is low (<70 mg/dl). Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) equations were developed to overcome these limitations, but few data are available whether these equations offer incremental usefulness over LDL-Cf.
Purpose
In this pragmatic study, we aimed to evaluate the agreement between LDL-C calculated using LDL-Cmh, LDL-Cs and LDL-Cf equations and to understand whether using LDL-Cmh or LDL-Cs instead of LDL-Cf leads to significant changes on the clinical decision-making
Methods
4196 cardiology outpatient cases that were included in a multicenter registry database were analyzed. Each case was assigned into a cardiovascular risk class using web-based SCORE (Systematic COronary Risk Evaluation) algorithm calibrated for high-risk European countries, and relevant European guidelines were used to assess LDL-C targets. LDL-Cf, LDL-Cs and LDL-Cmh were calculated as previously described.
Results
Compared to LDL-Cmh and LDL-Cs, LDL-Cf was able to correctly identify 96.9%-98.08% of cases as within or out of LDL-C target, respectively, while 1.95%-2.8% of cases were falsely identified as within LDL-C target. Kappa coefficients for agreement between LDL-Cf vs. LDL-Cmh and LDL-Cf vs. LDL-Cs were 0.868 and 0.918 (p < 0.001 for both). For patients not on anticholesterolemic drugs, decision to initiate treatment would be different in 1.2%-1.8% of cases if LDL-Cs or LDL-Cmh were used, respectively. For those already on anticholesterolemic drugs, decisions regarding to treatment intensification would be different in 1.5%-2.4% of cases if LDL-Cs or LDL-Cmh were used.
Conclusions
Friedewald equation had an excellent degree of agreement with the novel Martin/Hopkins and Sampson formulas in most cardiology outpatients, especially those within the lower end of the cardiovascular risk spectrum. In selected patients, especially those with high or very high risk in whom LDL-Cf < 70 mg/dl or those with a TG > 400 mg/dl, agreement was far worse and thus novel equations might have an incremental usefulness for clinical decision making.

Abstract
BACKGROUND The importance of monocyte count-to-HDL-cholesterol ratio (MHR) in cardio- vascular diseases has been shown in various studies. Ascending aortic dilatation (AAD) is a common complication in the patients with bicuspid aortic valve. In this study, we aimed to investigate the relationship between MHR and the presence of aortic dilatation in the patients with bicuspid aortic valve. METHODS The study population included totally 347 patients with bicuspid aortic valve.169 patients with aortic dilatation (ascending aorta diameter ≥ 4.0 cm) and 178 patients with no aortic dilatation. Echocardiographic and laboratory measurement was done and compared between groups. RESULTS The mean age of the participants was 44.7 ± 15.4 years and average ascending aorta diameter was 3.2 ± 0.3 cm in dilatation negative group and 4.4 ± 0.4 cm in positive group. MHR was significantly increased in in patients with aortic dilatation. MHR and uric acid level was independently associated with the presence of aortic dilatation in the patients with bicuspid aortic valve. CONCLUSION We found a significant relationship between MHR and aortic dilatation in the patients with bicuspid aortic valve.

Abstract
OBJECTIVE Bleeding is one of the most important causes of mortality in patients with acute coronary syndrome (ACS). This study therefore aimed to investigate bleeding risk in patients with ACS who were scheduled to receive dual antiplatelet therapy (DAPT) in Turkey. METHODS This was a multicentre, observational, cross-sectional cohort study. The study population included 963 patients with ACS from 12 centres in Turkey. We used the Predicting Bleeding Complication in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score to predict the bleeding risk for all the patients. The patients were divided into high (≥25) or low (˂25) bleeding risk groups based on their PRECISE-DAPT scores. RESULTS The mean PRECISE-DAPT score was 21.9. Overall, 32.2% of the patients had high PRECISE-DAPT scores (≥25). Compared with the male patients, the female patients had higher PRECISE-DAPT scores (28.2 ± 15.7 vs 18.4 ± 13.6, P ˂ .001). Among the females, the rate of patients with a PRECISE-DAPT score ≥25 was 53%, while among the male patients, the score occurred at a rate of 22%. The female patients had lower haemoglobin (Hb) levels than the male patients (12.1 ± 1.7 vs 13.8 ± 1.9, P ˂ .001) and lower creatinine clearance (70.7 ± 27.5 vs 88.7 ± 26.3, P ˂ .001). The in-hospital bleeding rates were higher among the patients with high PRECISE-DAPT scores than among those who did not have high scores. Furthermore, the patients with high PRECISE-DAPT scores had a higher in-hospital mortality rate compared with those with low PRECISE-DAPT scores (1% vs 0%, P = .11). CONCLUSIONS The mean PRECISE-DAPT score was high among the patients with ACS in this study, indicating that the bleeding tendency was high. This study showed that the PRECISE-DAPT score may help physicians determine the type and duration of DAPT, especially in patients with ACS in Turkey.

Abstract
Breast cancer is the second leading cause of cancer mortality among women. Mammography and tumor biopsy followed by histopathological analysis are the current methods to diagnose breast cancer. Mammography does not detect all breast tumor subtypes, especially those that arise in younger women or women with dense breast tissue, and are more aggressive. There is an urgent need to find circulating prognostic molecules and liquid biopsy methods for breast cancer diagnosis and reducing the mortality rate. In this study, we systematically evaluated metabolites and proteins in blood to develop a pipeline to identify potential circulating biomarkers for breast cancer risk. Our aim is to identify a group of molecules to be used in the design of portable and low-cost biomarker detection devices. We obtained plasma samples from women who are cancer free (healthy) and women who were cancer free at the time of blood collection but developed breast cancer later (susceptible). We extracted potential prognostic biomarkers for breast cancer risk from plasma metabolomics and proteomics data using statistical and discriminative power analyses. We pre-processed the data to ensure the quality of subsequent analyses, and used two main feature selection methods to determine the importance of each molecule. After further feature elimination based on pairwise dependencies, we measured the performance of logistic regression classifier on the remaining molecules and compared their biological relevance. We identified six signatures that predicted breast cancer risk with different specificity and selectivity. The best performing signature had 13 factors. We validated the difference in level of one of the biomarkers, SCF/KITLG, in plasma from healthy and susceptible individuals. These biomarkers will be used to develop low-cost liquid biopsy methods toward early identification of breast cancer risk and hence decreased mortality. Our findings provide the knowledge basis needed to proceed in this direction.

Abstract
In-stent restenosis (ISR) is a frequent complication of endovascular stents implantation, especially in the superficial femoral artery (SFA). Beyond the standard interventions, direct stent puncture (DSP) to the totally occluded SFA increases the success rate of the endovascular procedures. Multiple attempts are required to treat total occlusions most of time. DSP useful and safe technique and provide good angiographic results. Beside the classical DSP, in this case we discussed recanalization of totally occluded stent of superficial femoral artery with bidirectional stent puncture.

Abstract
BACKGROUND Sexual activity is an important indicator of quality of life and is significantly impaired in patients with heart failure (HF). Cardiac resynchronization therapy (CRT) has positive effects on cardiac dysfunction and endothelial dysfunction that lead to erectile dysfunction (ED). We aimed to evaluate whether CRT may improve sexual activity in patients with HF. METHODS In total, 136 patients (mean age 61.8 ± 12.8 years) were evaluated for the study. All patients filled the Sexual Health Inventory for Men (SHIM) questionnaire for evaluation of their erectile functions before CRT device implantation. One hundred eighty days after CRT device implantation, the patients were re-evaluated with SHIM questionnaire. RESULTS In the whole study population, SHIM test scores were significantly increased after CRT (12.99 ± 3.22 vs. 18.03 ± 5.00; p<0.001). The patients were divided into two groups according to the CRT response. The increase in SHIM test scores was significantly more in the response (+) group than in the response (-) group [response (+) group: 6.94 ± 3.36; p<0.001 vs. response (-) group: 0.81 ± 1.77; p = 0.465]. A positive CRT response was found to be an independent predictor of SHIM score (p<0.001). CONCLUSION Our study showed that CRT had positive effects on ED of patients with HF.

Abstract
PURPOSE To develop a medical ultrasound (US) simulation method using T1-weighted magnetic resonance images (MRI) as the input that offers a compromise between low-cost ray-based and high-cost realistic wave-based simulations. METHODS The proposed method uses a novel multi-ray image formation approach with a virtual phased array transducer probe. A domain model is built from input MR images. Multiple virtual acoustic rays are emerged from each element of the linear transducer array. Reflected and transmitted acoustic energy at discrete points along each ray is computed independently. Simulated US images are computed by fusion of the reflected energy along multiple rays from multiple transducers, while phase delays due to differences in distances to transducers are taken into account. A preliminary implementation using GPUs is presented. RESULTS Preliminary results show that the multi-ray approach is capable of generating view point-dependent realistic US images with an inherent Rician distributed speckle pattern automatically. The proposed simulator can reproduce the shadowing artefacts and demonstrates frequency dependence apt for practical training purposes. We also have presented preliminary results towards the utilization of the method for real-time simulations. CONCLUSIONS The proposed method offers a low-cost near-real-time wave-like simulation of realistic US images from input MR data. It can further be improved to cover the pathological findings using an improved domain model, without any algorithmic updates. Such a domain model would require lesion segmentation or manual embedding of virtual pathologies for training purposes.

Abstract
INTRODUCTION Lifestyle modification is an important component of the secondary prevention strategies; and a healthy diet is one of the cornerstones in management of the coronary heart disease. We aimed to investigate the dietary habits of the patients with history of coronary revascularization, characteristics of the ones with good adherence by using alternate MedDiet questionnaire. METHODS We included outpatients who had a history of coronary revascularization at least 6 months prior to enrollment. Each participant filled out a questionnaire to collect the data of demographics and clinical characteristics. Alternate MedDiet score was calculated to evaluate the Mediterranean style dietary adherence. Alternate MedDiet was originally based on 14-item questionnaire; we adjusted it to our population (max 13 points). RESULTS We enrolled 226 consecutive outpatients (age 61.7±10.9 years, 72% males). The median duration after revascularization was 60 months. A total of 112 (49.6%) patients had previous percutaneous coronary intervention (PCI), 77 (34.1%) had coronary by-pass graft surgery (CABG), and 36 (15.9%) had both revascularization procedures. The median MedDiet score was 6. Patients were stratified into two subgroups (MedDiet score ≥7 vs. <7). A total of 61 (26.9%) patients had MedDiet score ≥7. By univariate analysis, good MedDiet scores were associated with older age, waist circumference, body mass index, high education level, regular follow-up, duration after first revascularization and revascularization with CABG+PCI. In the multivariate analysis, high education level (P=.002, OR=8.212, 95%CI: 2.155-31.291) and duration after revascularization (P=.034, OR=1.007, 95%CI: 1.001-1.013) were independent predictors of good MedDiet scores. CONCLUSION The adherence rate to a healthy diet was low in patients with previous coronary revascularization. MedDiet score seems to be practical and useful item to evaluate the dietary habits in outpatient setting. Mediterranean diet adherence rates were associated with high education level, and duration after revascularization.

Abstract
The increasing volume of medical image data, as well as the need for multicenter data consolidation for big data analytics, require computer-aided medical image annotation (CMIA). Majority of the methods proposed so far do not exploit interdependencies between annotations explicitly. They further limit their annotations at a higher level than diagnostics and/or do not consider a standardized lexicon. A radiologist-in-the-loop semi-automatic CMIA system is proposed. It is based on a Bayesian tree structured model, linked to RadLex, and present preliminary results with liver lesions in computed tomography images. The proposed system guides the radiologist to input the most critical information in each iteration and uses a network model to update the full annotation online. The effectiveness of the system using this model-based interactive annotation scheme is shown by contrasting the domain-blind and domain-aware models. Preliminary results show that on average 7.50 (out of 29) manual annotations are sufficient for ${\text{95}}\%$ accuracy, which is ${\text{32.8}}\%$ less than the required manual effort when there is no guidance. The results also suggest that the domain-aware models perform better than the domain-blind models learned from data. Further analysis with larger datasets and in domains other than the liver lesions is needed.

Abstract
Anomalous left coronary artery arising from the pulmonary artery (ALCAPA) has been generally reported as an isolated lesion that is also called Bland-White-Garland syndrome. Herein we report a case of ALCAPA syndrome with an atrial septal defect in a 68-year-old woman. She had been asymptomatic until the age of 68. Echocardiographic examination revealed atrial septal defect, and coronary angiography showed that the left main coronary artery originated from the pulmonary artery and intensive collateral connections between the right and left coronary artery. In this case, it would appear that ALCAPA is associated with atrial septal defect.

Abstract
BACKGROUND The autonomic nervous system (ANS) is a potentially potent modulator of the initiation and perpetuation of atrial fibrillation (AF), whereas the presence of AF can activate and alter the ANS. The catheter ablation of AF (AFCA) may cause the cardiac ANS dysfunction, whereas restoration of sinus rhythm or sympathovagal imbalance by AFCA can reverse this process. Our principal goal was to investigate the short-term effect of AFCA on ANS functions evaluated by noninvasive chronotropic (CI), resting heart rate (RHR), and heart rate recovery (HRR) indices. METHOD A total of 45 patients were enrolled with symptomatic, drug refractory paroxysmal AF undergoing first cryoballoon (CB) pulmonary vein antrum isolation (PVAI) with one 28-mm CB using single 3-minute freeze techniques without bonus applications. All patients underwent symptom-limited exercise treadmill testing to evaluate noninvasive parameters of ANS before PVAI. For those patients who remained in sinus rhythm, an additional exercise test was repeated after 1 and 3 months after discharge. RESULTS The autonomic CI and RHR/HRR indices were impaired after PVAI and persisted post-PVAI 3 months. However, these parameters were not different in patients with and without recurrence. CONCLUSION This study demonstrated that the successful AFCA might concurrently impair the ANS parameters. The autonomic imbalance between the sympathetic and parasympathetic activity after AFCA could either become antiarrhythmic and/or proarrhythmic based on which of the two components was going to prevail after successful AFCA. The impaired ANS balance after PVAI might also be another hypothetical mechanism for AF recurrence particularly in the absence of PV reconnection.

Abstract
Atrial septal defect closure is now routinely performed using a percutaneous approach under echocardiographic guidance. Since some echocardiographic features play an important role in the assessment of the defect and safety of the procedure, the salient features of the anatomical variations seen in adults undergoing transcatheter device closure should be well known to prevent inadvertent adverse effect or complications. It has been reported that the valve of the inferior vena cava, Eustachian valve, could be mistaken as the atrial septum thus ending in a wrong diagnosis and causing inadvertent surgical or percutaneous closure of an Eustachian valve to interatrial septum. We present a concise article that brings out a practical issue encountered during device closure of atrial septal defects.

Abstract
BACKGROUND Recently fragmented QRS (fQRS) on electrocardiography (ECG) has been introduced as a predictor of myocardial scarring and myocardial ischemia in coronary artery disease (CAD). OBJECTIVE The aim of this study was to investigate the relationship between fQRS and fractional flow reserve (FFR) results in patients with the intermediate degree of coronary artery stenosis. METHODS A total of 301 consecutive patients who underwent coronary angiography (CAG) and FFR measurement for intermediate coronary artery stenosis were included in the study. The study patients were divided into two groups: the low FFR group (FFR value of ≤0.80) and normal FFR (FFR value of >0.80) group. Both groups were compared in terms of the presence of fQRS. RESULTS Of 301 patients, fQRS was detected in 128 (42.5%) and low FFR was detected in 115 (38.2%). In the low FFR group, fQRS was significantly higher (P<0.001). Multivariate analysis showed that fQRS was an independent predictor of myocardial ischemia in patients with intermediate coronary stenosis (OR=7.202, CI 95%, 4.195-12.367; p<0.001). The presence of fQRS had 70% sensitivity and 74% specificity for the prediction of FFR≤0.80. CONCLUSION In clinical practice, the presence of fQRS on ECG is associated with myocardial ischemia in patients with intermediate coronary stenosis.

Abstract
INTRODUCTION The relationship between inflammation and mortality after acute pulmonary embolism (APE) has previously been investigated with different variables (platelet/lymphocyte ratio, etc). OBJECTIVES We investigated the predictive value of lymphocyte to monocyte ratio (LMR) for mortality in first 30 days after APE. METHODS The study population included 264 APE patients of which 230 patients were survivors, 34 patients were non-survivors. RESULTS LMR was significantly lower in non-survivors after APE (P < .001). Neutrophil-to-lymphocyte ratio (NLR) was higher in non-survivors after APE (P < .001). Platelet-to-lymphocyte (PLR) had no significance between both groups (P: .241). Simplified pulmonary embolism severity index and LMR were independent predictors of mortality in patients with APE (P: .008 and P: .001, respectively). CONCLUSION LMR as a novel marker of inflammation seemed to be an independent predictor of short-term mortality in patients with APE.
