Abstrakt		Objective: The concept of cardiac surgery on the beating heart is acceptable rationale for the cardiac surgery in the next millenium. Beating heart (off-pump) coronary artery bypass grafting (CABG) techniques have led us to consider the possibility for performing the aortic and mitral valve surgery (mitral valve repairs and replacements - with or without CABG) on the beating heart with the technique of retrograde oxygenated coronary sinus perfusion. Methods: We used the technique of retrograde oxygenated blood coronary sinus perfusion in 78 patients (Group All) (36 patients were with extremely low ejection fraction (Group X) - 62 % of whom were in New York Heart Association (NYHA) class 4 and 34% of whom were in NYHP. class 3). The procedures for the patients were: aortic, mitral and tricuspid valve surgery, in combination with CABG in ischemic patients. CABG was done in all the cases off-pump. In addition, we performed a case match study for 37 patients with good ejection fraction (51.65 +- 11.88) (Beating Heart Group) operated on the beating heart with most appropriate group of patients (No. 37) operated in our institutions on arrested heart (ejection fraction 51.07 +- 12.93) (Arrested Heart Group). The case match selection criteria were: gender, left ventricular ejection fraction, atrial fibrillation, hypertension, pulmonary hypertension, and diabetes. The selected beating heart group and selected arrested heart groups were without statistically significant differences for the mentioned criteria. Results:There were statistically significant differences between Beating Heart Group and Arrested Heart Group in the duration of Cardiopulmonary Bypass Time (69.35 +- 13.52 min. versus 93.59 +- 28.54 min.), p<0.001, and statistically significant differences in Aortic Cross Clamp Time (46.5 +- 8.95 min. versus 61.5 +- 18.34 min.), p<0.001.
