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	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: 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	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 m 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	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

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.
