Öğe Accessory mitral valve tissue: An overview of clinical and practical implications(Aves, 2021) Yalta, Kenan; Yetkin, Ertan; Yalta, Tulin; Taylan, Gokay[Abstract Not Available]Öğe Accessory mitral valve tissue: anatomical and clinical perspectives(Elsevier Science Inc, 2021) Yetkin, Ertan; Cuglan, Bilal; Turhan, Hasan; Yalta, KenanMitral valve is a complex cardiac structure composed of several components to work in synchrony to allow blood flow into left ventricle during diastole and not to allow blood flow into left atrium during systole. Accessory mitral valve tissue (AMVT) was defined as existence of any additional part and parcel of valvular structure which has an attachment to normal mitral valve apparatus in left-sided cardiac chambers. AMVT may present itself in different clinical circumstances ranging from a silent clinical course to thromboembolic events, heart failure, left ventricular outflow tract obstruction, and severe arrhythmia. This article reviews the clinical perspectives of AMVT in terms of symptoms, diagnosis, and treatment, providing a new anatomical classification regarding the location of AMVT. Briefly type I refers to AMVT having attachments on the supra leaflets level, type II refers to attachments on the mitral leaflets, and type III refers to attachment below the mitral leaflets. Increased awareness and widespread use of echocardiographic techniques would increase recognition of AMVT in patients with heart murmurs but otherwise healthy and in those with left ventricular outflow tract obstruction or tissue which causes subaortic stenosis and with unexplained cerebrovascular events.

Current guideline recommends the use of oral anticoagulants in patients with atrial fibrillation and history of previous thromboembolism. However, anticoagulant treatment in patients with LV systolic dysfunction with sinus rhythm and without history of previous thromboembolism is still on debate. Recent epidemiologic date has reported increased stroke rate in patients with systolic HF shortly after diagnosis. This review focuses on the possible causes of increased stroke rate shortly after the diagnosis of HF and subsequently suggests a rationale for the use of oral anticoagulant in these patient groups.Öğe Atrial fibrillation and peripheral varicose vein: Where is the connection?(Sage Publications Inc, 2023) Yetkin, Ertan; Atmaca, Hasan; Yalta, Kenan[Abstract Not Available]Öğe Atrial septal aneurysm and cryptogenic stroke: an arrhythmic approach to pathophysiology(Hygeia Press Corridori Marinella, 2023) Yetkin, Ertan; Atmaca, Hasan; Cuglan, Bilal; Yalta, KenanIn patients with cryptogenic strokes, more attention should be paid to the possible existence of paroxysmal atrial fibrillation, especially in those with atrial septal aneurysm with or without patent foramen ovale.Öğe Atrioventricular block in the setting of cardiac sarcoidosis: further implications(Springer, 2023) Yalta, Kenan; Yetkin, Ertan[Abstract Not Available]Öğe Atypical patterns of the de Winter sign: even more confusion in clinical practice(Polish Cardiac Soc-Polskie Towarzystwo Kardiologiczne, 2021) Yalta, Kenan; Ozkan, Ugur; Yetkin, Ertan[Abstract Not Available]Öğe An Atypical Presentation of Decubitis Angina in a Patient with Coronary Artery Disease and Aortic Regurgitation: Case Report(Thieme Medical Publ Inc, 2023) Yetkin, Ertan; Atmaca, Hasan; Yalta, KenanDecubitis angina briefly refers to a pain occurring during the night or in recumbent position. Herewith, we present a case of decubitis angina occurring immediately after lying down in a patient with coronary artery disease and aortic regurgitation. The patient was successfully treated by percutaneous coronary intervention. It should be kept in mind that early-onset chest pain immediately after lying down might be a sign of myocardial ischemia or acute coronary syndrome especially in the presence of coronary artery disease and aortic regurgitation.Öğe Atypical variants of takotsubo cardiomyopathy: mechanistic and clinical implications(Science Press, 2020) Yalta, Kenan; Yetkin, Ertan; Taylan, Gokay[Abstract Not Available]Öğe Basal takotsubo syndrome: A multifaceted entity with potential implications(Elsevier Espana Slu, 2021) Yalta, Kenan; Ozturk, Cihan; Yalta, Tulin; Yetkin, Ertan[Abstract Not Available]Öğe Bone mineral density: A potential determinant of atherosclerotic plaque morphology in established coronary artery disease?(Elsevier Ireland Ltd, 2011) Sivri, Nasir; Yalta, Tulin; Yalta, Kenan; Yetkin, Ertan; Aksoy, Yuksel[Abstract Not Available]Öğe Cardiac Biomarkers in the Setting of Asthma Exacerbations: a Review of Clinical Implications and Practical Considerations(Current Medicine Group, 2020) Yalta, Kenan; Yalta, Tulin; Gurdogan, Muhammet; Palabiyik, Orkide; Yetkin, ErtanPurpose of Review The present paper aims to highlight clinical implications of elevated cardiac biomarkers and associated myocardial dysfunction in a variety of cardiac and non-cardiac scenarios in patients with an asthma exacerbation, and to propose a basic algorithm for cardiovascular evaluation and triage (and hence, for further management) of these patients primarily based on evaluation of cardiac biomarkers along with basic diagnostic modalities and specific cardiac symptoms in the hospital setting. Recent Findings Elevation of cardiac biomarkers in the setting of an asthma exacerbation mostly signifies a new-onset subclinical myocardial dysfunction/injury generally associated with certain asthma-related factors including acute hypoxemia and bronchodilator therapy, and usually has a limited prognostic value in these patients. On the other hand, elevation of these biomarkers in patients with an asthma exacerbation might also denote a variety of certain life-threatening cardiac or non-cardiac conditions associated with significant myocardial dysfunction (acute coronary syndromes (ACSs), sepsis, etc.) that might be masked by the rampant course of the asthma exacerbation, and hence, might possibly go undetected potentially aggravating the prognosis in a portion of these patients. In patients with an asthma exacerbation, it seems imperative to timely diagnose and manage emerging diverse clinical conditions particularly through the guidance of cardiac biomarkers and associated myocardial dysfunction patterns in an effort to improve overall prognosis in these patients.Öğe Cardiac myxoma as a potential trigger of takotsubo cardiomyopathy: A brief review on mechanistic and clinical perspectives(Pagepress Publ, 2022) Yalta, Tulin; Yalta, Kenan; Ozkan, Ugur; Yetkin, ErtanIn clinical practice, cardiac myxomas constitute the majority of benign cardiac neoplasms, and might potentially present with a variety of embolic, obstructive as well as constitutional symptoms. On the other hand, these neoplasms might be potentially associated with the evolution of takotsubo cardiomyopathy (TTC) that is universally considered as a transient form of acute myocardial dysfunction. Accordingly, the present paper primarily aims to focus on potential mechanisms and associated clinical implications of TTC evolution in the setting of cardiac myxomas.Öğe Cardiac myxomas in an unusual location: A glimpse into their potential characteristics(Aves, 2021) Yalta, Kenan; Ozkan, Ugur; Yalta, Tulin; Yetkin, Ertan[Abstract Not Available]Öğe Carotid intima-media thickness:. a new marker of patients with uterine leiomyoma(Elsevier, 2014) Aksoy, Yuksel; Sivri, Nasir; Karaoz, Banu; Sayin, Cenk; Yetkin, ErtanObjective: To determine whether or not there are any significant differences in carotid intima-media thickness between patients with uterine leiomyoma and controls. Study Design: Patients whose ages were between 40 and 50 years, with body mass index <30 kg/m(2), and with a pathological diagnosis of uterine leiomyoma constituted the study group. Control subjects had no uterine leiomyoma proven by sonography. Demographic, clinical, and drug history data were collected. Right, left and mean carotid intima-media thickness measurements were obtained by ultrasonography. Results: Carotid intima-media thickness and serum high-density lipoprotein (HDL) levels were significantly different between the groups (p = 0.0001 and p = 0.001 respectively), being respectively higher and lower in the leiomyoma group than in controls. Stepwise binary logistic regression analysis revealed that uterine leiomyoma development ratio was 159.32 times higher when carotid intima-media thickness was over 0.61 mm (p = 0.0001). In patients with uterine leiomyoma, carotid intima-media thickness was significantly less in patients taking statins compared to those not on these drugs (p = 0.0001). Conclusion: The present study demonstrated a positive association between carotid intima-media thickness and the presence of uterine leiomyoma. Conversely, an inverse association was suggested between HDL and uterine leiomyoma. These findings suggest that women with uterine leiomyoma might have an increased risk of subclinical atherosclerosis. (C) 2014 Elsevier Ireland Ltd.

Copeptin, the C-terminal portion of provasopressin, is a novel NH of the AVP system, and is known to be co-released with AVP from hypothalamus (neurohypophysis). As a surrogate marker of the AVP system, copeptin has gradually replaced AVP in several clinical studies largely due to its structural and methodological advantages. Copeptin has been regarded as a marker of non-specific stress response, and has also been suggested to have clinical implications in a variety of non-cardiovascular (pneumonia, sepsis, etc.) and cardiovascular conditions (heart failure and acute coronary syndromes (ACSs, etc.)). However, current data on relation of copeptin with other cardiovascular conditions (arrhythmias, etc.) are still insufficient. The present review primarily focuses on general features of copeptin, its general clinical implications, and specifically aims to cover its potential clinical value in a variety of cardiovascular conditions.
