Objectives: In the present study, the purpose was to investigate the usability of the preoperative C-reactive protein/albumin ratio as a predictor of the development of postoperative atrial fibrillation in patients who undergo coronary artery bypass grafting. Patients and methods: A total of 336 patients (228 males, 108 females; mean age: 58.1±8.5 years; range 35 to 88 years) who underwent isolated coronary artery bypass grafting with cardiopulmonary bypass between January 2019 and January 2021 were reviewed in the single-center, retrospective study. Those with postoperative sinus rhythm were considered Group 1 (n=258), and patients with postoperative atrial fibrillation were defined as Group 2 (n=78). Preoperative routine biochemical tests of the patient groups were evaluated. Results: The incidence of postoperative atrial fibrillation was 23.2%. Statistically significant differences were detected between the two groups in terms of age (p

BACKGROUND: In this study, we aimed to investigate the effects of thiol-disulfide homeostasis in patients undergoing on-pump coronary artery bypass grafting. METHODS: Between January 2018 and October 2018, a total of 51 patients (43 males, 8 females; mean age 61.8±8.7 years; range, 38 to 78 years) who underwent isolated on-pump coronary artery bypass grafting were included. Thiol-disulfide homeostasis parameters were studied in the preoperative period (T1), 30 min after the removal of cross-clamp (T2), and postoperative sixth h (T3). Hemodynamic parameters such as atrial fibrillation and inotropic support requirement of the patients were evaluated in the postoperative period. RESULTS: There were significant differences in the measured thiol-disulfide homeostasis parameters at different time points of surgery (p

OZ Amac: Bu calismada koroner arter baypas greftleme (KABG)’nin aortik fonksiyonlar uzerindeki etkisi incelendi. Ca­lis­ma­ pla­ni:­ Ayni cerrahi ekip tarafindan kardiyopulmoner baypas ile KABG ameliyati yapilan cokdamar koroner arter hastaligi (KAH) olan ardisik 32 hasta (ort. yas 61.6±9.4 yil) calismaya alindi. Hastaligin siddeti Gensini skor indeksi ile hesaplandi. Aortik kesit uyumu, aortik esneklik ve aortik sertlesme gibi aortik fonksiyon indeksleri ekokardiyografi ile ameliyat oncesi donemde ve ameliyat sonrasi ucuncu ve altinci aylarda hesaplandi. Bul gu lar: Aortik fonksiyonlar yuksek Gensini skoru (ortalama 98.3±38.1) ile ciddi veya yaygin KAH’si olan hastalarda ameliyat sonrasi donemde iyilesti. Aortik kesit uyumu ameliyat oncesi 2.62±1.5 cm2/mmHg’den ameliyat sonrasi ucuncu ayda 3.52±1.6 cm2/mmH’ye (p=0.21) ve altinci ayda 3.79±1.5 cm2/mmHg’ye (p

Tup torakostomisi, kardiyovaskuler cerrahi kliniklerinde rutin olarak kullanilan bir girisimdir. Tup torakostomisi bircok durumda hayat kurtarici bir islem olmakla birlikte, mortaliteye neden olabilecek ciddi komplikasyonlari vardir. Klinigimizde koroner arter baypas greft (KABG) ameliyati yapilmis 71 yasinda erkek bir hastada, ameliyat sonrasi apikal gogus tupu yerlestirilmesinin alisilmadik bir komplikasyonu olarak cikan aort perforasyonu gelisti. Bu komplikasyon basarili bir sekilde tedavi edilerek, hasta tam sifa ile taburcu edildi. Ozellikle torakarli tup torakostomisi uygulanan hastalarda bu nadir ancak olumcul komplikasyonun gelisebilecegi akilda tutulmalidir. Keza, ameliyat sonrasi donemde bu hastalarda mediastinal yer degisikligi olup olmadigina dikkat edilmelidir. Anah tar soz cuk ler: Aort rupturu; gogus tupu; torakostomi. Tube thoracostomy is a routine intervention which is used in cardiovascular surgery clinics. Although it is a life-saving intervention in most cases, it has serious complications leading to mortality. We encountered an ascending aortic perforation, an unusual complication following apical chest tube insertion, in a 71-year-old male patient who underwent coronary artery bypass graft (CABG) surgery in our clinic. This complication was managed successfully and the patient was discharged with a complete recovery. This rare but fatal complication should be considered for the patients undergoing tube thoracostomy, particularly with a toracar. It should also be noticed whether the patients have mediastinal shift in postoperative period.

Amac: Bu calismada, ikinci kez yinelenen kapak degisimi olgularinda ameliyat oncesi ve ameliyat sirasi risk faktorleri, kullanilan kapak turleri ve ameliyat yontemleri arastirildi. Ca­lis­ma­ pla­ni:­Klinigimizde Ocak 1994 Aralik 2009 tarihleri arasinda toplam 2089 kapak replasmani gerceklestirildi ve bu ameliyatlarin 182’sini (112 kadin, 70 erkek) yinelenen kapak ameliyatlari olusturdu. Bul gu lar: Yinelenen ameliyat icin ortalama yas 49.2±27.4 yil, ilk ameliyat ile ikincisi arasindaki ortalama sure ise 11.8±5.7 yil olarak hesaplandi. Tekrar ameliyat sonrasi takip suresi 2.6±1.3 yil idi. Toplam 142 (%78) hastadan biyoprotez kapak, 40 (%22) hastadan ise mekanik kapak sokuldu. Toplam degistirilen kapak sayisi 221 idi. Toplam takilan kapak sayisi 219 idi, sadece kapak onarimi ise uc hastada uygulandi. Tekrar ameliyatta takilan kapaklarin 197’si (%90) mekanik kapak idi. Hastalarin ameliyat oncesi ekokardiyografik bulgulari, esas sorunun kapak disfonksiyonu (%84) oldugunu gosterdi, bunu enfeksiyon takip ediyordu. Yinelenen ameliyat uygulanan 15 olgu (%8.2) ameliyat sirasinda veya ameliyattan sonraki ilk bir ay icinde kaybedildi. So­nuc:­ Yinelenen kalp kapak ameliyatlari, standart ameliyat islemleri kullanilarak, kabul edilebilir mortalite ile uygulanabilir. Bu ameliyatlarda riski artiran nedenler, acil girisimler ve enfeksiyona bagli nedenlerdir, bununla birlikte pulmoner hipertansiyon, yinelenen kapak degisimi cerrahisi olasiligini artiran bir neden degildir. Anah tar soz cuk ler: Aort kapak; mitral kapak; yinelenen kalp kapak ameliyatlari. Background:­ In this study, we aimed to investigate the preoperative and operative risk factors in patients undergoing valve replacement for the second time, including the types of valves and surgical methods used. Methods: Between January 1994 and December 2009, a total of 2089 valve replacements were performed in our clinic, and 182 (112 females, 70 males) of these operations (8.7%) were repeat valve surgeries. Results:­The mean age for repeat surgery was 49.2±27.4 years while the mean time elapsed between the first and second surgeries was 11.8±5.7 years. The follow-up period after repeat surgery was 2.6±1.3 years. Bioprosthesis valves were removed from a total of 142 patients (78%), and mechanical valves were removed from 40 patients (22%). In total, 221 valves were replaced. The total number of valves implanted was 219, and valve repair alone was performed on three patients. Of the valves implanted in repeat surgery, 197 (90%) were mechanical valves. The preoperative echocardiography findings revealed that the major problem (84%) observed was valve dysfunction, followed by infection. Fifteen patients (8.2%) who underwent repeat surgery died during the operation or within the first month afterwards. Conclusion:­Repeat heart valve surgery may be performed using the standard surgical procedures with acceptable mortality. Factors increasing the probability of repeat surgery include emergency interventions and infections; however, pulmonary hypertension is not a factor that increases the probability of repeat valve replacement surgery.
