Item Comparison of non-vitamin K antagonist oral anticoagulants and well-controlled warfarin in octogenarians with non-valvular atrial fibrillation: Real-world data from a single tertiary center(2021) Akgun, Arzu Neslihan; Karacaglar, Emir; Bal, Uğur Abbas; Ozin, Mehmet Bulent; 34236320Objective: Atrial fibrillation (AF) is the most common arrhythmia in clinical practice, and its prevalence increases with age. Nevertheless, data about the use of oral anticoagulants (OACs) among patients with >= 80 years remains limited. This study aimed to evaluate the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin in octogenarians with non-valvular AF (NVAF). Methods: Medical records of 387 patients who were >= 80 years and diagnosed with NVAF in our hospital between January 2017 and December 2019 were evaluated retrospectively. Patients with NVAF were divided into 2 groups (NOACs and warfarin), and the incidence of stroke/systemic embolism and major bleeding were analyzed. Results: A total of 322 patients were included in the study. The median follow-up duration was 10.9 months for the NOACs group and 12.1 months for the warfarin group. The primary efficacy outcome was stroke/systemic embolism, and the primary safety outcome was major bleeding. A total of 220 patients were taking NOACs, and the most preferred NOACs were apixaban (53.6%), rivaroxaban (29.5%), dabigatran (13.2%), and edoxaban (3.6%) in this order. During a mean follow-up of 302.7 patient-years, the incidence of stroke or systemic embolic events was slightly higher among patients with warfarin but the difference was not statistically significant (p=0.862). The incidence rates of major bleeding events were similar between the treatment groups (p=0.824). Conclusion: Our study revealed that the safety and efficacy outcomes are similar between the 2 treatment groups in octogenarians with NVAF.Item Acute Coronary Syndrome In Geriatric Patients In An Intensive Care Unit(2021) Keskin, Suzan; Akgun, Arzu Neslihan; Ciftci, Orcun; Muderrisoglu, Ibrahim HaldunObjective: The advancing age of acute coronary syndrome and the ageing population are leading to an increase in the number of elderly patients with acute coronary syndrome in our clinical practice. In our study, we aimed to investigate the effect of acute coronary syndrome in the geriatric patient group. Materials and Method: We retrospectively included geriatric patients who were in intensive care units because of different diagnoses, who also showed an acute coronary syndrome, and who had been diagnosed using the sequential organ failure assessment score. This score is used to describe the condition of a patient with sepsis and the extent of organ damage during treatment in an intensive care unit. We reviewed patients who were at Baskent University Faculty of Medicine between 25 March 2015 and 12 March 2020. Results: We included 63 patients aged 77.27 +/- 7.65 years. There were 40 (63.5%) males and 23 (36.5%) females. A total of 42 (89.4%) patients died in the first 5 months, one (2.1%) died between the 6th and 10th months, two (4.3%) between the 11th and 20th months, and two (4.3%) between the 21st and 30th months. We found a significant relationship between the sequential organ failure assessment score and mortality rate (p<0.05). The sequential organ failure assessment score was reliable in predicting mortality in geriatric patients with acute coronary syndrome, with 57% sensitivity and 75% specificity. Conclusion: Mortality of geriatric patients with acute coronary syndrome can be significantly determined using the sequential organ failure assessment scores.Item Direct aortic transcatheter aortic valve implantation(2021) Karacaglar, Emir; Akgun, Arzu Neslihan; Aydinalp, Alp; Beyazpinar, Deniz Sarp; Sezgin, Atila; Muderrisoglu, Haldun; 34623302Transcatheter aortic valve implantation (TAVI) is a safe and effective alternative to surgical valve replacement in intermediate and even in low-risk patient cohorts. Direct aortic (DAo) route may be used in patients with severe peripheral vascular disease. Here, we present an 88-year old patient hospitalized with cardiogenic shock. Echocardiography revealed severe aortic valve stenosis with aortic valve area 0.5 cm(2), mean gradient of 55 mmHg, and peak gradient 92 mmHg. TAVI was considered by the Institutional Heart Team. Multislice computed tomography (MSCT) revealed severe peripheral vascular disease, decreased calibration of abdominal aorta, and multiple large vulnerable atherosclerotic plaques. The patient was scheduled for a DAo TAVI. A 26-mm Medtronic CoreValve Evolut R valve was implanted after predilatation with median sternotomy. The patient was discharged after 96 hours. Although transfemoral (TF) access is used as the default approach for TAVI, it was contraindicated in our patient owing to severe peripheral vascular disease and decreased calibration of the abdominal aorta at its narrowest point (4.5 mm) with multiple large vulnerable atherosclerotic plaques. Careful preprocedural MSCT evaluation is essential and directly affects the success of the procedure. MSCT is also mandatory to confirm the best cannulation zone that must be met for a successful DAo TAVI.Item Relation of Preoperative and Postoperative Echocardiographic Parameters With Rejection and Mortality in Liver Transplant Patients(2020) Yilmaz, Kerem Can; Ciftci, Orcun; Akgun, Arzu Neslihan; Muderrisoglu, Haldun; Boyacioglu, Sedat; Haberal, Asuman Nihan; Moray, Gokhan; Haberal, Mehmet; 0000-0001-8926-9142; 0000-0002-9635-6313; 0000-0003-2498-7287; 0000-0002-9370-1126; 0000-0001-9852-9911; 0000-0002-3462-7632; 29790458; W-5233-2018; AAG-8233-2020; AAJ-1331-2021; AAE-1041-2021; AAE-7637-2021; AAK-4587-2021; AAJ-8097-2021Objectives: Survival in liver transplant after end-stage liver disease is associated with major cardiac functions. In a significant number of patients with end-stage liver disease, cardiac dysfunctions may be observed, which can include high-output heart failure, cardiac valve disease, and pulmonary venous and arterial hypertension. All of these affect perioperative survival. The aim of our study was to determine whether preoperative and postoperative echocardiographic parameters, specifically right heart-related tricuspid regurgitation, estimated systolic pulmonary arterial pressure, and tricuspid annular plane systolic excursion, are associated with rejection and mortality in liver transplant patients. Materials and Methods: Adult patients (> 18 years old) who underwent liver transplant at our center between January 2011 and March 2017 were included in the study, with 64 patients retrospectively screened. The echocardiographic images that were taken immediately before and immediately after liver transplant were evaluated. The patients were divided into 2 groups according to rejection data and mortality. All parameters were analyzed for both variables. Results: For the 24 patients with liver rejection and 40 patients without liver rejection, there were no statistically significant differences in terms of demographic data, echocardiographic parameters, and laboratory data. However, when patients were evaluated according to survival, there was a statistically significant difference between these 2 groups concerning the echocardiography parameters of systolic pulmonary arterial pressure (P = .005), tricuspid annular plane systolic excursion (P = .001), and postoperative right ventricular width (P = .01). Conclusions: Echocardiography, being a simple and easily accessible technique that is reliable in excluding pulmonary hypertension diagnosis, can be used as a guide in the evaluation of right ventricular function and tricuspid regurgitation, particularly in patients who are not hemodynamically stable before and after liver transplant.
