Abstract

Objectives: The aim of this study was to evaluate the left ventricular functions with transthoracic echocardiography after coronary bypass surgery. Methods: Sixty-four patients who underwent coronary bypass surgery between January 2008 and March 2009 were retrospectively evaluated. The diagnosis, age and gender of the patients, presence of diabetes mellitus and/or hypertension, smoking, and left ventricle functions before and after surgery were recorded. Results: The mean age of the patients was 58 ± 6,2 years. Forty-four of 64 patients were male, and 20 were female. The lowest ejection fraction was measured in two patients as 30% preoperatively. The mean preoperative and postoperative left ventricle ejection fractions were 48 ± 5.4% and 58 ± 2.4% respectively. This difference was found statistically significant. The mortality rate of by-pass surgery was 4.68% (3 patients). Conclusion: The left ventricular functions were significantly recovered after coronary by-pass surgery.

Abstract

Amaç: Bu çalışmada koroner by-pass cerrahisi yapılan hastaların sol ventrikül fonksiyonlarının transtorasik ekokardiografi ile değerlendirilmesi. Yöntemler: Ocak 2008 ile Mart 2009 tarihleri arasında koroner by-pass yapılan 64 hasta geriye dönük olarak incelendi. Hastaların tanısı, yaşı, cinsiyeti, diabetes mellitus ve hipertansiyon tanıları ve sigara kullanımı durumları tespit edildi. Operasyon öncesinde ve sonrasında sol ventrikül fonksiyonlarına bakıldı. Bulgular: Çalışmaya dâhil edilen 64 hastanın 44\'ü erkek 20\'si kadın idi. Yaş ortalaması 58 ± 6,2 yıl (43–84 yaş) idi. Çalışmaya alınan hastalardan en düşük sol ventrikül ejeksiyon fraksiyonuna sahip 2 hastanın değerleri %30 idi. Hastaların 4\'üne dört damar, 34\'üne üç damar, 21\'ine iki damar, 5\'ine ise tek damar koroner by-pass cerrahisi yapıldı. Kanamadan dolayı 4 hasta (%6.2) revizyona alındı. Preoperatif sol ventrikül ejeksiyon fraksiyonu ortalama %48 ± 5,4 iken, altıncı aydaki kontrolde solventrikül ejeksiyon fraksiyonu ortalama %58,7 ± 2,4 idi. Bu fark istatiksel olarak anlamlı bulundu. Operasyonla ilişkili 3 hastada (%4,68) mortalite görüldü. Sonuç: Koroner by-pass yapılan hastalarda postoperatif sol ventrikül fonksiyonlarında anlamlı düzelmeler tespit edildi.
