Article Citation - WoS: 3Citation - Scopus: 1Caval Valve Implantation Procedure in 7 Cases of Torrential Tricuspid Regurgitation and Step-By Description of the Procedure(Kare Publ, 2025) Sarıçam, Ersin; Barcin, Cem; Çelebi, Aksüyek Savaş; Asfour, Mohamed; Bozbas, Huseyin; İlkay, Erdoğan; Cam, Ersin; Celebi, Savas A.Tricuspid regurgitation (TR) is an increasingly prevalent and clinically significant health problem.1 Due to the growing understanding of the importance of TR, the tricuspid valve has transitioned from being a forgotten valve to one of significant concern. Tricuspid regurgitation is often functional, and as it progresses to moderate or severe stages, hospital admissions increase and prognosis worsens.1,2 There are no effective pharmacological treatments for TR, and the 5-year survival rate with medical management is reported to be less than 50%.3 Therefore, early diagnosis and timely intervention for TR is crucial. Both surgical and percutaneous treatment options are available for severe TR. The mortality rate for isolated TR surgery is generally high.4 In recent years, transcatheter treatments have become feasible for this patient group, and accumulating evidence shows that transcatheter treatment is superior to medical management.5,6 Transcatheter interventions for TR can be performed in 4 ways, 2 involving repair and 2 involving valve We aimed to present our experience with transcatheter caval valve implantation (CAVI) in 7 patients with torrential TR who were not suitable for surgical intervention or transcatheter edge-to-edge repair (T-TEER) due to severe coaptation defects, review the current literature, and provide a step-by-step description of the procedure.Article Citation - WoS: 13Citation - Scopus: 14Evaluation of procedural and clinical outcomes of transcatheter aortic valve implantation: A single-center experience(Kare Publ, 2020) Karaduman, Bilge Duran; Kayaoğlu, Hüseyin Ayhan; Keleş, Telat; Bozkurt, Engin; Ayhan, HuseyinObjective: Transcatheter aortic valve implantation (TAVI) is an established alternative to surgical aortic valve replacement. Our study aimed to evaluate the implementation of TAVI at our large-volume center, having an all-comer patient population with short and long-term follow-ups. Methods: This retrospective, single-center analysis included 556 consecutive patients with symptomatic severe aortic stenosis (AS) who underwent TAVI between July 2011 and December 2019. Results: The mean age of the entire population was 77.6±7.9 years, and 54.9% were women. The Society of Thoracic Surgeons (STS) mean score of the cohort was 6.0%±3.5%. The balloon-expandable valve (Sapien XT, Sapien 3; Edwards Lifesciences, Irvine, California) was the most frequently used valves in this cohort (94.6%). Transfemoral access was used in 96.3% of patients. Implantation success was achieved in 96.6% of cases. During the TAVI procedure, 7.2% of patients required permanent pacemaker implantation, with 37.5% in the Lotus valve group needing the most permanent pacemakers. The mean length of hospital stay for the entire cohort was 4.5±2.3 days. Overall, 22 (3.9%) in-hospital deaths occurred before hospital discharge. The mean follow-up period was 15.1±14.9 months for all patients, and a significant improvement was noted in all echocardiographic parameters and functional capacity. Paravalvular leak (PVL) was documented in 18.9% patients, mild in 17.9%, and moderate in 1% at discharge. No cases with severe PVL, necessitating additional procedures. The multiple logistic regression analysis revealed that sex, STS score, baseline SYNTAX score, bicuspid valve morphology, common femoral artery diameter, and post-TAVI PVL were independent predictors of overall mortality. Conclusion: To our knowledge, this study, which is the largest single-center real-world experience of TAVI in Turkey, demonstrated low complication rates with favorable short- and mid-term THV performance in patients undergoing TAVI.Article Citation - WoS: 8Citation - Scopus: 9Impact of Coronary Revascularization on Outcomesof Transcatheter Aortic Valve Implantation(Aves, 2021) Karaduman, Bilge Duran; Ayhan, Hüseyin; Keles, Telat; Bozkurt, EnginObjective: Although the effect of coronary revascularization on clinical outcomes before and after transcatheter valve implantation (TAVI) is debatable, there is currently insufficient data to determine the most appropriate revascularization strategy. In this study, we present our single-center experience of percutaneous coronary intervention (PCI) and its effect on clinical outcomes and mortality in patients undergoing TAVI.Methods: We performed a retrospective analysis of 526 consecutive patients at our center, and 127 patients with obstructive coronary artery disease were included in the study. Patients were divided into two groups: the revascularization group (group 1) and the non-revascularization group (group 2). Procedural complications and long-term all-cause mortality rates were compared between the two groups.Results: Of the 526 patients, group 1 comprised 65 patients (12.3%) who underwent PCI, and group 2 comprised 62 patients (11.7%) who did not undergo revascularization. According to Valve Academic Research Consortium 2 criteria, post-procedural complications, including pericardial effusion, stroke, major vascular complications, major bleeding, and emerging arrhythmias, were similar between the groups. A Kaplan–Meier survival curve analysis showed no significant difference between the revascularization and non-revascularization groups (Overall: 40.0±2.8 month; 95% CI 34.4-45.6 month, p=0.959). After adjustment for basal SYNTAX score, chronic kidney disease stage, previous myocardial infarction, and baseline troponin levels, the long-term survival of group 1 was significantly longer when compared with group 2 (p=0.036). In 75.4% of cases, PCI was performed within 11.0±14.7 days before or after TAVI as a staged procedure. In 13.8% of cases, PCI was performed simultaneously with TAVI. While there was no significant difference in in-hospital, 6-month, and 1-year mortality rates between the simultaneous and staged PCI groups, there was a significant difference in 30-day mortality (11.1% vs. 0%, respectively; p=0.016).Conclusion: Peri-procedural and long-term safety outcomes and mortality rates are not significantly different between revascularized and non-revascularized patients, and neither staged nor simultaneous PCI have adverse outcomes in patients undergoing TAVI.Article Citation - WoS: 4Citation - Scopus: 5The Clinical, Functional, and Radiological Features of Hand Osteoarthritis: Tlar-Osteoarthritis Multi-Center Cohort Study(Turkish League Against Rheumatism, 2022) Duruoz, Mehmet Tuncay; Gursoy, Didem Erdem; Tuncer, Tiraje; Altan, Lale; Ayhan, Figen; Bal, Ajda; Ugurlu, Hatice; Çay, Hasan Fatih; Durmaz, Berrin; Gurer, Gülcan; Sarıkaya, Selda; Sezer, IlhanObjectives: This study aims to evaluate the clinical, functional, and radiological features of hand osteoarthritis (OA) and to examine their relationships in different geographic samples of the Turkish population. Patients and methods: Between April 2017 and January 2019, a total of 520 patients (49 males, 471 females; mean age: 63.6 +/- 9.8 years) with hand OA were included in the study from 26 centers across Turkiye by the Turkish League Against Rheumatism (TLAR). The demographic characteristics, grip strengths with Jamar dynamometer, duration of hand pain (month), the severity of hand pain (Visual Analog Scale [ VAS]), and morning stiffness were evaluated. The functional disability was evaluated with Duruoz Hand Index (DHI). The Kellgren-Lawrence (KL) OA scoring system was used to assess the radiological stage of hand OA. Results: The DHI had significant correlations with VAS- pain (r= 0.367, p<0.001), duration of pain (r=0.143, p=0.001) and bilateral handgrip strengths (r=-0.228, p=0.001; r=-0.303, p<0.001). Although DHI scores were similar between the groups in terms of the presence of hand deformity (p= 0.125) or Heberden's nodes (p=0.640), the mean DHI scores were significantly higher in patients with Bouchard's nodes (p=0.015). The total number of nodes had no significant correlations with the VAS-pain and DHI score (p>0.05). The differences between the groups of radiological hand OA grades in terms of age (p= 0.007), VAS-pain (p<0.001), duration of pain (p<0.001), and DHI (p<0.001) were significant. There were no significant differences between radiological hand OA grades according to the duration of the stiffness, grip strength, and BMI (p>0.05 for all). Conclusion: In our population, the patients with hand OA had pain, functional disability, and weak grip strength. The functional impairment was significantly correlated with the severity of the pain, and the functional status was worse in high radiological hand OA grades.
