Publication Open Access Acute inferior myocardial infarction in a patient with a prosthetic aortic valve and high international normalized ratio(TERMEDIA PUBLISHING HOUSE LTD, 2014) ATAŞ, HALİL; Atas, Halil; Sari, Ibrahim; Delil, Kenan; Ileri, Cigdem; Samadov, FuadST elevation acute myocardial infarction in patients with a mechanical prosthetic valve is rare and usually due to inadequate anticoagulation. We present a case of acute inferior myocardial infarction in a patient with a prosthetic aortic valve and high international normalized ratio, which has not been reported previously.Publication Open Access Short and Long Term Mortality Predictors in Octogenarians with Acute Coronary Syndromes(2018-06-30) ÖZBEN SADIÇ, BESTE; Atas, Halil; Tigen, Kursat; Ozben, Beste; Kartal, Fatih; Gurel, Emre; Atas, Dilek B; Sari, İbrahim; Basaran, YeldaPurpose: Octogenarians with acute coronary syndromes have higher mortality and morbidity due to higher prevalence of comorbidities and frailty. The aim of this study was to explore the predictors of short and long term mortality in octogenarians with ACS. Methods: Ninety-eight consecutive octogenarians presenting with acute coronary syndrome (mean age:84±3 years, 56 male) were included. All patients underwent coronary angiography and were given optimal medical treatment. The primary end point was cardiovascular mortality in hospital and at one year. Results: Fifteen patients died during hospitalization and 20 patients died after discharge within the first year. ST-segment-elevation myocardial infarction and hypotension were significantly more prevalent in the in-hospital mortality group while atrial fibrillation and hyponatremia were more prevalent in the long-term mortality group. All deceased patients had significantly lower left ventricular ejection fraction and glomerular filtration rate. Cox analysis revealed ST-segment-elevation myocardial infarction, hypotension and left ventricular ejection fraction as independent predictors of in-hospital mortality while hyponatremia, atrial fibrillation and renal dysfunction as independent predictors of long term mortality. Conclusion: It would be reasonable to pay further attention to octogenarians with acute coronary syndrome if they are presenting with ST-segment-elevation myocardial infarction, and have hypotension, impaired left ventricular function, hyponatremia, atrial fibrillation or renal dysfunction, which are associated with increased mortality.Publication Open Access The impact of right ventricular function assessed by 2-dimensional speckle tracking echocardiography on early mortality in patients with inferior myocardial infarction(WILEY, 2018-03) ÇİNÇİN, AHMET ALTUĞ; Kanar, Batur G.; Tigen, Mustafa K.; Sunbul, Murat; Cincin, Altug; Atas, Halil; Kepez, Alper; Ozben, BesteBackgroundRight ventricular (RV) involvement in inferior myocardial infarction (MI) increases in-hospital morbidity and mortality. HypothesisRV systolic dysfunction assessed by 2-dimensional speckle tracking echocardiography (STE) might be a predictor of early mortality in patients with acute inferior MI. MethodsEighty-one consecutive patients with acute inferior MI (mean age, 60.812.7years; 18 females) were included. RV myocardial involvement was defined as an elevation >1mm in V-1 or V4R within 12hours of symptom onset. RV function was assessed by STE. Patients were followed for 30days for all-cause mortality. ResultsThirty-eight patients had RV myocardial involvement, and they had significantly lower tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (RVS), and left ventricular (LV) and RV global longitudinal strain (GLS). Nine patients (11%) died within 30days. The mean age of mortality group was higher with more female frequency. They had significantly higher pro-BNP, hs-troponin T, and creatinine levels, but lower hemoglobin levels. TIMI 3 flow was significantly less achieved in mortality group. RV myocardial involvement was more frequent in the mortality group, and they had significantly lower TAPSE, RVS, and LV and RV GLS. Multivariate analysis revealed that age and RV GLS were independent predictors of early mortality. RV GLS -14% predicted early mortality in patients with acute inferior MI with a sensitivity of 88.9% and a specificity of 62.5% (AUC: 0.817, P =0.002). ConclusionsRV GLS may be useful in predicting early mortality in patients with acute inferior MI.Publication Open Access Prediction of subclinical left ventricular dysfunction by speckle-tracking echocardiography in patients with anti-neutrophil cytoplasmic antibody--associated vasculitis(2021-12-24) İZGİ, TUBA NUR; ATAŞ, HALİL; VELİOĞLU, ARZU; BARUTÇU ATAŞ, DİLEK; ILGIN, CAN; ALİBAZ ÖNER, FATMA; DİRESKENELİ, RAFİ HANER; ARIKAN, İZZET HAKKI; TUĞLULAR, ZÜBEYDE SERHAN; AŞICIOĞLU, EBRU; Izgi T. N., Atas D., ATAŞ H., Akaslan D., Ilgin C., VELİOĞLU A., ARIKAN İ. H., Alibaz-Oner F., DİRESKENELİ R. H., TUĞLULAR Z. S., et al.Objectives: This study aims to evaluate left ventricular functions using speckle-tracking echocardiography (STE) in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Patients and methods: Between June 2018 and July 2019, a total of 31 AAV patients (17 males, 14 females; median age: 53 years; range, 47 to 62 years) and 21 healthy controls (11 males, 10 females; median age: 56 years; range, 46 to 60 years) were included in the study. Clinical and biochemical characteristics of all participants were recorded. All participants underwent conventional and two-dimensional STE. The receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value of serum N-terminal prohormone of brain natriuretic peptide (NT-pro-BNP) that predicted subclinical left ventricular dysfunction. The Spearman correlation analysis was used to determine the correlation between left ventricular global longitudinal strain (LV-GLS) and NT-pro-BNP. Results: The LV-GLS was lower in AAV patients (19.3% vs. 21.7%, respectively; p=0.014). NT-pro-BNP was negatively correlated with LV-GLS (p=0.005, r=0.401). Conclusion: Subclinical left ventricular dysfunction can be detected by STE in patients with AAV who have free of clinically overt cardiovascular disease. The LV-GLS is negatively correlated with serum NT-pro-BNP levels.Publication Open Access Relationship between Coronary Collateral Circulation and Left Ventricular End Diastolic Pressure and Plasma Levels of N-Terminal Pro-B-Type Natriuretic Peptide in Patients with Chronic Total Occlusion(ELSEVIER SCIENCE INC, 2013-10) ATAŞ, HALİL; Samadov, Fuad; Akhundova, Aysel; Akaslan, Dursun; Atas, Halil; Sari, Ibrahim; Yesildag, OsmanPublication Open Access Subclinical Regional Myocardial Dysfunction Assessed by Two-Dimensional Speckle Tracking Echocardiography in Systemic Sclerosis Patients with Fragmented QRS Complexes(ELSEVIER SCIENCE INC, 2013-10) ÇİNÇİN, AHMET ALTUĞ; Sunbul, Murat; Tigen, Kursat; Ozen, Gulsen; Durmus, Erdal; Kivrak, Tarik; Cincin, Altug; Ozben, Beste; Atas, Halil; Direskeneli, Haner; Basaran, YeldaPublication Open Access Effects of balloon pulmonary angioplasty procedure on electrocardiographic parameters in patients with chronic thromboembolic pulmonary hypertension(2023-03-01) KOL, AYHAN; KEPEZ, ALPER; ATAŞ, HALİL; MUTLU, BÜLENT; KOL A., KEPEZ A., Akaslan D., Kanar B., ATAŞ H., MUTLU B.Aim: The aim of the present study was to evaluate the value of electrocardiography (ECG) in predicting post-operative hemodynamic improvement in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BPA).Material and methods: A total of 32 patients were included in the study. During ECG analysis, parameters that have been suggested to be related to right ventricular hypertrophy and/or dilatation were evaluated. The sig-nificance of the change in each parameter obtained at the pre-BPA visit and at the scheduled control visit 6 months after BPA was tested. In addition to ECG analysis, data related to right heart catheterization (RHC) and echocardiography, B-type natriuretic peptide (BNP) levels and World Health Organization (WHO) functional classifications of all patients were also recorded. The relationship between the amount of possible change in ECG parameters and the amount of possible change in hemodynamic parameters was investigated.Results: The Daniel score, which has been suggested to have prognostic value in acute pulmonary embolism, decreased from 8.22 +/- 5.68 to 6.56 +/- 5.55 after the BPA procedure (p: 0.035). Among all parameters studied, only T wave height (V2 t) in V2 derivation changed significantly from-0.77 +/- 2.39 to 1.27 +/- 2.58 mm (p: 0.036). The amount of change in V2 T was found to significantly correlate with the amount of change in systolic right ventricular pressure, mean pulmonary artery pressure, pulmonary vascular resistance, and systemic vascular resistance.Conclusion: Postprocedural T wave changes in lead V2 might serve as a marker of hemodynamic improvement in patients with CTEPH who undergo BPA.Publication Open Access A Case of Decompensated Heart Failure Due to Prosthetic Valve Dysfunction: Quick Diagnosis with Fluoroscopy(AVES, 2015-07-23) ÇİNÇİN, AHMET ALTUĞ; Cincin, Ahmet Altug; Ozben, Beste; Atas, Halil; Tigen, KursatIntroduction: Patients with decompensated heart failure due to prosthetic heart valves consists of a challenging group in emergency clinics for both diagnosis and treatment. Despite the important role in diagnosis, transthoracic echocardiography (TTE) remains unsatisfactory in many cases. Case Report: A 65-year-old female patient with decompensated heart failure and a history of valve replacement surgery 6 years ago for both mitral and aortic valves was admitted. The diagnosis of prosthetic valve dysfunction was successfully fixed using fluoroscopy, despite the fact that initial TTE was not adequate enough to assess valve function. Conclusion: In cases that TTE is not accessible or inadequate enough to assess valve function, fluoroscopy is a practical and quick method to rule out prosthetic valve dysfunction.Publication Open Access Percutaneous and surgical removal of two cases of embolized totally implantable venous access devices that were implanted a long time ago(2015-03-06) ÇİNÇİN, AHMET ALTUĞ; Atas, Halil; Sari, Ibrahim; Cincin, Altug; Tigen, KursatPublication Open Access A case of heart failure mimicking COVID-19 pneumonia: The role of clinical and chest computed tomography findings in the differential diagnosis(AVES, 2020) MUTLU, BÜLENT; Dogan, Zekeriya; Ileri, Cigdem; Yildrim, Cagan; Atas, Halil; Cincin, Altus; Ozben, Beste; Mutlu, BulentAcute heart failure (HF) is one of the most common cardiac emergencies. Pulmonary edema caused by HF may mimic an exudative disease on chest computed tomography scans. Coronavirus disease 2019 (COVID-19) emerged in China in December 2019 and quickly spread around the world. During this pandemic period, the need to exclude the possibility of COVID-19 pneumonia in patients with acute dyspnea may cause a delay in the diagnosis and treatment of patients with acutely decompensated HF who have similar symptoms. This case report describes a diabetic patient admitted with dyspnea one week after she suffered an acute myocardial infarction. The objective of this report is to draw attention to the differential diagnosis of HF and COVID-19 pneumonia.
