Sibel Catirli Enar graduated from İstanbul University, İstanbul Medical School in 1981. She is specialized in anesthesiology and critical care in İstanbul Medical School in 1985 and in cardiology at İstanbul University İnstitute of Cardiology in 1992. She became Associate Prof.of Cardiology in 2000, Fellow of European Society of Cardiology in 2010, Fellow of American Society of Echocardiography in 2012, Fellow of International Society of Cardiac Ultrasound in2012 and Fellow of American College of Cardiology in 2016.Working at Turkiye Hospital and Memorial Hospital in Istanbul/Turkey  since 2000. She worked as a research fellow in Cleveland Clinic of Foundation-USA 1996-1998 and in University of Alabama at Birmingham-USA 2006-2008 as well. She is the member  of Medical Societies: Turkish Society of Cardiology, European Society of Cardiology (member of cardiac imaging (EACVİ), heart failure association and valvular heart disease groups), American Society of Echocardiography (ASE), American College of Cardiology (ACC), American Heart Association (AHA), İnternational Society of Cardiac Ultasound (İSCU). She is the author of a chapter in” Metabolic syndrome in women” (2015) and contributor in “Interesting Cases in Echocardiography”-(N.Nanda-2017).  She is referee for scientific abstracts,member of scientific comittes and referee in scientific journals.Has taken part in multicenter studies. She has publications in National and International Journals. She served as speaker and moderator in National and International Congresses. Her area of interest is echocardiography.


Heart failure with preserved ejection fraction (HFpEF) affects nearly half of the patients with clinical signs of heart failure.HFpEF is considered to be a disease of the left ventricle (LV). It is characterized by impaired diastolic function due to to abnormal relaxation and increased chamber stiffness.The role of right ventricle (RV) has not been well characterized  in HFpEF. Recently several studies have described the role of RV in these patients by echocardiography, and few studies by CMR. In these studies,it has been found that addition of RV dysfunction is related with worse prognosis. The following explanation has been proposed: Impaired LV diastolic function causes passive rise in left atrial (LA) pressure and consecutively in PAWP and pulmonary artery (PA) pressure. Pulmonary artery compliance (PAC) decreases and adds to the increasing resistance against the right ventricle.RV fails to compensate pressure overload,dilates and finally RV failure occurs.Left atrial dilation is also present in these patients. Although HFpEF is considered as a disease of the left ventricle,RV dysfunction is also affected. Diabetes Mellitus and hypertension  present  with HFpEF predominantly, however RV dysfunction is also observed in these patients. Improvement of right heart imaging by echocardiography and CMR will be very helpful in the diagnosis and determining the prognosis.
