Öğe A Rare Coronary Anomaly: Single Coronary Artery; Two Cases(2025) Ayhan, Selçuk; Köseoğlu, Cemal; Öncel, Can RamazanWe present two cases of a rare coronary anomaly—single coronary artery—identified incidentally during routine coronary angiography. Both patients presented with symptoms of chest pain and exertional angina. In both cases, the anomaly is located in the right sinus of Valsalva (R-1-A) and crosses the heart anterior to the right ventricle. (Figure 3) The first patient experienced significant stenosis in the proximal left anterior descending artery, which was successfully treated with percutaneous stent implantation. The second patient's chest pain was managed effectively with medical therapy alone. These cases highlight that a single coronary artery, often asymptomatic, can exist as a congenital anomaly in patients experiencing myocardial ischemia due to atherosclerotic coronary artery disease. Furthermore, they demonstrate that percutaneous coronary intervention, including stent placement, offers a promising treatment approach. In the literature, coronary artery bypass surgery should particularly be considered as a treatment option for these coronary anomalies. However, it has also been shown that in selected cases, percutaneous intervention or medical therapy can be viable alternatives.Öğe An under-diagnosed caused of myocardial infarction: Coronary embolism(2025) Öncel, Can Ramazan; Türk, Recep; Köseoğlu, CemalThe coronary embolism (CE) is a rare cause of acute coronary syndrome (ACS). The most common cardiovascular disease linked to coronary embolism is atrial fibrillation (AF). Despite the acknowledgment of the entity, it is regarded an under-diagnosed cause of ACS, and there is uncertainty over the short and long term prognosis of these patients. In this case report, we aimed to provide information about the diagnosis and treatment process of a patient who presented with acute inferior myocardial infarction caused by coronary embolism.Öğe Can Diastolic Dysfunction Develop as a Result of Premature Ventricular Complex?(2023) Köseoğlu, Cemal; Öncel, Can RamazanTo the Editor, We have read the article by Keleş et al1 entitled “Does premature ventricular com- plex impair left ventricular diastolic functions?’’ with great interest which was published in Anatol J Cardiol 2023; 27: 217-222. In the present study, the authors reported that patients with premature ventricular complex exhibited a lower early diastolic strain rate than the normal population and this parameter can be used to predict left ventricular diastolic dysfunction in the study population. Also, the authors reported that patients with premature ventricular complex may have a higher risk of left ventricular diastolic dysfunction than healthy individuals.1 We would like to emphasize some important points about this well-written study...Öğe Clinical Importance of P Wave Dispersion in Mitral Valve Prolapse(2024) Öncel, Can Ramazan; Köseoğlu, Cemal; Çoner, AliObjective: Mitral valve prolapse (MVP) is a widespread valvulopathy present in 2–6% of the population, affecting more than 170 million people globally. The objective of this study was to assess P wave dispersion (PWD) in patients with MVP to identify the presence of cardiovascular autonomic dysfunction and the potential risk of developing atrial arrhythmias in these patients. Materials and Methods: The study included 40 healthy control participants (Group 1), 41 patients with non-classic MVP (Group 2), and 36 patients with classic MVP (Group 3). Demographic and clinical characteristics were documented upon admission. An electrocardiographic assessment was conducted to quantify PWD values for both patients and the control group. Results: The minimum P wave duration was lower in classic MVP patients than in controls and non-classic MVP patients (63±3.6 vs. 70±2.0, p<0.001; 63±3.6 vs. 63±3.6, p<0.001, respectively). P wave dispersion was higher in classic MVP patients than in non-classic MVP patients (47.3±3.2 vs. 39.0±2.3, p=0.001). A significant positive correlation was detected between PWD and maximum P wave duration (Pmax), minimum P wave duration (Pmin), maximal leaflet displacement, maximal leaflet thickness, and left atrial diameter (LAD) (r=0.723, p<0.001; r=- 0.771, p<0.001; r=0.557, p<0.001; r=0.770, p<0.001; r=0.517, p<0.001, respectively). Maximum leaflet thickness and maximum leaflet displacement were independent predictors of increased PWD in linear regression analysis (?=1.456, p<0.001, ?=-0.851, p<0.001). Conclusion: Patients with classic MVP exhibited prolonged PWD values compared with non-classic MVP patients and normal controls.Öğe Determining ECG Parameters for Electrical Risk Score in Patients with Non-ST Elevation Myocardial Infarction(2025) Öncel, Can Ramazan; Çoner, Ali; Köseoğlu, Cemal[Abstract Not Available]Öğe Factors Associated with Aortic Stiffness Index, Aortic Velocity Propagation, and Epicardial Fat Thickness in Pregnancy(Kare Publications, 2025) Köseoğlu, Cemal; Öncel, Can Ramazan; Çoner, AliI found the study titled “The Effect of Number of Pregnancies on Aortic Stiffness Index, Aortic Velocity Propagation, and Epicardial Fat Thickness” by Şaylık et al.,1 published in the Archives of the Turkish Society of Cardiology, to be highly interesting. We would like to highlight several important aspects of this well-written study.Öğe Management of Ventricular Pseudoaneurysms(2024) Köseoğlu, Cemal; Öncel, Can Ramazan[Abstract Not Available]Öğe Predicting Postoperative Atrial Fibrillation Using HARMS2-AF Score(2024) Öncel, Can Ramazan; Köseoğlu, Cemal; Dagasan, Goksel; Çoner, Ali; Ayhan, Selçuk; Akkaya, Özgür; Karahan, OğuzBackground: Postoperative atrial fibrillation (POAF) remains a common complication after cardiac surgery. The ability to accurately identify patients at risk through previous risk scores is limited. This study aimed to evaluate the new HARMS2-AF risk score to pre- dict POAF after coronary artery bypass grafting (CABG) surgery. Methods: In this retrospective cohort study, we included 265 patients undergoing CABG surgery from 2022-2023. Data were obtained from the medical files of the patients and hospital records. Each patient was assigned a HARMS2-AF risk score. A univariate and multivariate regression analyses were done to analyze independent predictors of POAF. Results: Of 265 patients, 49 had postoperative atrial fibrillation. HARMS2-AF score was significantly higher in patients with POAF. Age, sleep apnea, left atrial diameter (LAd), and HARMS2-AF score were independently associated with POAF. A HARMS2-AF score ? 4.5 predicted POAF with 91% sensitivity and 64% specificity (AUC = 0.787, 95% CI = 0.731- 0.842, P < .001). Conclusion: The HARMS2-AF score is a strong predictor of atrial fibrillation (AF) develop- ment after isolated CABG surgery. It can be used as a novel stratification tool to estimate AF after cardiac surgery.
