This paper presents a case with pre-Eisenmenger patent ductus arteriosus complicated by pulmonary artery dissection, and explains how she was surgically treated.Publication Metadata only Improvements in quality of life in septuagenarians versus octogenarians undergoing trans-catheter aortic valve replacement(2016-01-01T00:00:00Z) KAHRAMAN AY, Nuray; AY, YASİN; Sonmez, Osman; Vatankulu, Mehmet Akif; Goktekin, Omer; KAHRAMAN AY, NURAY; AY, YASİNBackground Very elderly patients represent a distinct patient group in clinical setting in terms of a decision for trans-catheter aortic valve replacement (TAVR) when one considers the potential improvement in the quality of life (QoL) on one hand and the benefit to risk ratio on the other. This study aimed to compare functional and QoL outcomes of TAVR between octogenarians and septuagenarians. Methods This prospective cohort study included 136 elderly patients (70 to 89 years of age), who underwent transfemoral TAVR due to degenerative aortic stenosis. Patients were allocated into one of the following age groups: septuagenarians (n = 67) and octogenarians (n = 69). Preoperative and early postoperative clinical parameters were recorded. In addition, QoL of the patients was evaluated using SF-36 questionnaire preoperatively and six month postoperatively. Results Groups were similar in terms of early postoperative mortality and morbidity parameters. The mean New York Heart Association (NYHA) class improved after TAVR in both groups. In addition, all SF-36 norm-based scale and SF-36 summary scale scores improved significantly in both groups during the postoperative period. Postoperatively, physical functioning, general health and physical component summary scores were significantly better in the septuagenarian group (P = 0.02, 0.01, 0.03, respectively). Conclusion Although the improvement in the QoL in terms of physical health was more marked in septuagenarians than in octogenarians, substantial benefits on the QoL and particularly on mental health seem to justify re-consideration of TAVR indications in the very elderly.Publication Metadata only Çok Katmanlı Akış Modülatör Stent İmplantasyonu Sonrası Devam Eden Kaçağın Endovasküler Tedavisi(2021-10-28T00:00:00Z) Selçuk, Emre; Museyeva, Sayagat; İnan, Bekir; Türkkolu, Şevket Tuna; Masrioğlu, Ahmet; Akal, Ramazan; Aydın, Cemalettin; Ay, Yasin; Köksal, Cengiz; SELÇUK, EMRE; MUSEYEVA, SAYAGAT; İNAN, BEKİR; TÜRKKOLU, ŞEVKET TUNA; MASRİOĞLU, AHMET; AKAL, RAMAZAN; AYDIN, CEMALETTİN; AY, YASİN; KÖKSAL, CENGİZPublication Metadata only Diagnostic value of transthoracic echocardiography and computerized tomography for surgically confirmed late tamponade after cardiac surgery(2019-12-01T00:00:00Z) AY, YASİN; KAHRAMAN AY, Nuray; AY, YASİN; KAHRAMAN AY, NURAYBackground Late tamponade after cardiac surgery is a clinically obscure condition presenting significant diagnostic challenges, since it may be difficult to detect using routine imaging studies. This study is aimed to investigate the diagnostic value of transthoracic echocardiography (TTE) and contrast-enhanced computerized tomography (cCT) in the diagnosis of late tamponade following open-heart surgery. Methods A total of 88 patients who underwent reoperation after cardiac surgery with suspected late cardiac tamponade were included in this retrospective study. All the patients had TTE and cCT examinations before reoperation. The diagnostic values of these imaging modalities were investigated using surgically confirmed late tamponade as the standard. Results The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of an optimal cutoff value of greater than 3.1 cm pericardial fluid thickness on cCT images for predicting surgically confirmed late tamponade were 91.4%, 66.6%, 97.4%, 36.3%, and 89.7%, respectively. Accordingly, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of TTE for the diagnosis of late tamponade were 34.1%, 50.0%, 90.3%, 5.2%, and 35.2%, respectively. The cCT provided false-negative results in seven patients (8%), while this figure was 54 (61.4%) for that of TTE. Conclusion Computerized tomography imaging seems to represent a superior imaging technique in terms of visualizing the intrapericardial fluid collections after cardiac surgery and has the potential to readily diagnose late tamponade and effectively prevent unnecessary morbidity and mortality.Publication Metadata only Transposition of the great arteries,secundum atrial septal defect,and dextrocardia with systemic cardiac valve insufficiency.(2012-11-08T00:00:00Z) BAŞEL, HALİL; AYDIN, CEMALETTİN; AY, YASİN; İNAN, BEKİR; Teker, Melike elif; TÜRKKOLU, ŞEVKET TUNA; ZALLOUM, Raed nj; ZEYBEK, RAHMİ; AYDIN, CEMALETTİN; AY, YASİN; İNAN, BEKİR; TÜRKKOLU, ŞEVKET TUNA; ZEYBEK, RAHMİPublication Metadata only The Effects of Levosimendan Exposure on Oxidant/Antioxidant Status and Trace Element Levels in the Pulmonary Artery of Rats(2013-06-01T00:00:00Z) AY, YASİN; AYDIN, CEMALETTİN; Basel, Halil; Bektaş, Hava; Bulut, Gulay; İNAN, BEKİR; Ay, NURAY; Demir, Ismail; AY, YASİN; AYDIN, CEMALETTİN; İNAN, BEKİR; KAHRAMAN AY, NURAYWe investigated both the effect of levosimendan and the role of oxidant/antioxidant status and trace element levels in the pulmonary artery of rats. Fourteen male Wistar albino rats were randomly divided into two groups of seven animals each. Group 1 was not exposed to levosimendan and served as a control. Levosimendan (12 mu g/kg) diluted in 10 ml 0.9 % NaCl was administered intraperitoneally to group 2. Animals of both groups were killed after 3 days, and their pulmonary arteries were harvested to determine changes in tissue oxidant/antioxidant status and trace element levels. The animals in both groups were killed 72 h after the levosimendan exposure treatment, and pulmonary arteries were harvested to determine levels of the lipid peroxidation product MDA and the antioxidant GSH as well as the decreased activity of antioxidant enzymes such as SOD, GSH-Px and CAT. It was found that MDA levels increased in pulmonary artery tissues of rats after levosimendan administration. The GSH level decreased in the pulmonary artery of rats after levosimendan treatment. Co, Mn, Fe, Cd and Pb levels were significantly higher (P < 0.001) and Mg, Zn and Cu levels significantly lower (P < 0.001) in the levosimendan group compared to the control group. These results suggest that levosimendan treatment caused an increase in free radical production and a decrease in antioxidant enzyme activity in the pulmonary artery of levosimendan-treated rats. It also caused a decrease or increase in the levels of many minerals in the pulmonary artery, which is an undesirable condition for normal pharmacological function.
