Item Çalışan kalpte yapılan koroner baypasta trimetazidine ve glikoz-insülin-potasyum kullanımının miyokard üzerine etkileri(Uludağ Üniversitesi, 2003) Ercan, Abdulkadir; Ener, Serdar; Uludağ Üniversitesi/Tıp Fakültesi/Kalp ve Damar Cerrahisi Anabilim Dalı.Çalışan kalpte koroner baypas esnasında trimetazidine ve glikoz -insülin - potasyum (GİK) solüsyonunun miyokardiyal iskemi ve reperfüzyon hasarı üzerine etkilerini araştırmak üzere ileri dönük, randomize, kontrollü klinik çalışma planlandı. Çalışan kalpte koroner cerrahisi yapılacak toplam 45 koroner arter hastası randomize olarak üç gruba ayrıldı. Grup 1 (n=15) hastalar cerrahi öncesi 7 günlük süreyle bir tablet (trimetazidine 20 mg) günde 3 kez olarak aldı. Grup 2 (n=15) hastalar anestezi indüksiyonu sonrası ilk 12 saat boyunca intravenöz GİK solüsyonunu aldı. Grup 3 (n=15) hastalar kontrol grubu olarak değerlendirildi. Tüm hastalarda kan glikozu, kreatin kinaz MB (CK-MB), Troponin I (Tn I) ölçümleri cerrahi öncesi, postoperatif 5. dakikada, 12. saatte, 24. saatte, ve 48. saatte yapıldı. Ortalama pulmoner arter basıncı ve kardiyak indeks, ameliyata ait veriler ve morbidite tüm hastalarda preoperatif ve postoperatif dönemlerde kaydedildi. Preoperatif risk profilleri ve operatif değişkenler karşılaştırıldığında her iki grup arasında fark yoktu. Tn I ve CK-MB değerleri koroner baypas sonrası anlamlı olarak yükseldi ancak gruplar arasında anlamlı fark yoktu. Kardiyak indeks ve ortalama pulmoner arter basıncı gruplar arasında anlamlı farklılık göstermiyordu. Trimetazidine ile ameliyat öncesi tedavi ve GİK infüzyon protokolü çalışan kalpte koroner baypas cerrahisinde iskemi-reperfüzyon hasarının azaltılması amacıyla kullanılmaktadır. Bu çalışma sonuçları trimetazidine ve GİK infüzyon protokolünün iskemi-reperfüzyon hasarı üzerine önemli etkisi olmadığını göstermiştir.Item A comparison of off-and on-pump beating-heart coronary artery bypass surgery on long-term cardiovascular events(Clinics Cardive Publication, 2017) Gürbüz, Orçun; Kumtepe, Gencehan; Özkan, Hakan; Karal, İlker Hasan; Ercan, Abdulkadir; Ener, Serdar; Yolgösteren, Atıf; Uludağ Üniversitesi/Tıp Fakültesi/Kalp ve Damar Cerrahisi Anabilim Dalı.; AAG-2372-2021; 57193236800Objective: Our aim was to compare short-term outcomes and long-term major adverse cardiovascular event (MACE)-free survival and independent predictors of long-term MACE after off-pump (OPCAB) versus on-pump beating-heart (ONBHCAB) coronary artery bypass grafting (CABG). Methods: We retrospectively reviewed data of all consecutive patients who underwent elective CABG, performed by the same surgeon, from January 2003 to October 2009. A propensity score analysis was carried out to adjust for baseline characteristics and a total of 398 patients were included: ONBHCAB (n = 181), OPCAB (n = 217). Results: OPCAB was associated with significantly shorter ventilation times (p < 0.001), intensive care unit stay (p < 0.001) and hospital stay (p < 0.001). The total blood loss was significantly more in the ONBHCAB group (p < 0.001), and accordingly, the number of transfused blood units was significantly lower in the OPCAB group (p < 0.001). Incidence of peri-operative renal complications were significantly higher in the ONBHCAB group (p = 0.004). The OPCAB group showed significantly lower long-term MACE-free survival (p = 0.029). The mean number of transfused blood units was the only independent predictor of MACE (HR: 1.218, 95% CI: 1.089-1.361; p = 0.001). Conclusion: OPCAB provided better long-term MACE-free survival compared with ONBHCAB. Fewer units of blood transfused following OPCAB surgery may have been the main reason for this result.Publication Evaluation of polylactide film for prevention of pericardial adhesion in a rabbit model(Baycinar Medical Publ-Bayçınar Tıbbi Yayıncılık, 2015-01-01) Gürbüz, Orçun; Ercan, Abdulkadir; Biçer, Murat; Kumtepe, Gencehan; Bayram, Sami; Şenkaya, Işık; Saba, Davit; BİÇER, MURAT; BAYRAM, AHMET SAMİ; ŞENKAYA SIĞNAK, IŞIK; Saba, Davit; Uludağ Üniversitesi/Tıp Fakültesi/Kalp Damar Cerrahisi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Cerrahisi Anabilim Dalı.; ABC-2231-2020; ABB-7580-2020; DTC-2331-2022; DPS-9311-2022Background: This study aims to evaluate the efficacy of a bioabsorbable polylactide film, which was proven to be effective in preventing pelvic adhesions, in prevention of postoperative pericardial adhesions in an animal model.Methods: Forty New Zealand white rabbits were divided equally into control and treatment groups. Subjects were performed left anterior thoracotomy and partial pericardiectomy followed by epicardial abrasion. In control groups (group 1 and 2), the pericardium was left open to allow retrosternal adhesions. In treatment groups (group 3 and 4), the pericardial defect was closed with 0.02 mm bioabsorbable polylactide film. Postoperative macroscopic and microscopic evaluations were made by the same blinded observers at the end of the third week in group 1 and 3, and at the end of the sixth week in group 2 and 4.Results: Macroscopic and histopathologic examinations revealed no significant differences between control and treatment groups in terms of adhesion formation. However, polylactide film supported the growth of a mesothelium-like layer in the treatment groups.Conclusion: Although polylactide film assists in the regeneration of mesothelial cells layer, it does not prevent the development of pericardial adhesions.Item Left ventricular aneurysm in a 4-year-old boy(Texas Heart Institute, 2005) Ercan, Abdulkadir; Şenkaya, Işık; Semizel, Evren; Çil, Ergün; Uludağ Üniversitesi/Tıp Fakültesi/Kalp Damar Cerrahisi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Sağlığı ve Hastalıkları Anabilim Dalı/Kardiyoloji Bölümü.; Uludağ Üniversitesi/Tıp Fakültesi/Kalp Damar Cerrahisi Anabilim Dalı.; AAH-3865-2021; AAG-9324-2021; 55398003800; 56495079800; 12646191300; 35587943300A 4-year-old boy with a history of acute lymphoblastic leukemia was referred for evaluation of cardiac function due to progressive decline in exercise tolerance and to cardiomegaly on chest radiography. Six months earlier, there had been no such finding on the chest film. Echocardiography, also performed at the earlier visit, had yielded a normal result.
