Some points in the article caught our attention. Inherited bleeding disorders need pre-planning in the preoperative and operative period of cardiac surgery (2). Were the bleeding disorders questioned, while taking the anamnesis of the included patients?Atrial fibrillation is one of the most common complications after coronary artery bypass surgery (3). Anticoagulant therapy is inevitable in patients with atrial fibrillation. Patients with anticoagulation therapy due to atrial fibrillation or any other cause is not mentioned in the text which may be associated with postoperative bleeding.And finally, when the current literature is reviewed, it is seen that the use of peroperative tranexamic acid has a reducing effect on bleeding after coronary bypass surgery. (4). In this study, did the authors use tranexamic acid? We congratulate the authors about their manuscript. We look forward to hear the authors’ opinions on these matters.Bastopcu M, Özhan A, Erdoğan SB, Kehlibar T.

Routine use of del Nido cardioplegia compared with blood cardioplegia in all types of adult cardiac surgery procedures. J Card Surg. 2020;10.1111/jocs.15060In this study; Del Nido cardioplegia group has shorter aortic cross-clamp time for coronary artery by pass graft patients. But there is no sufficient data about the number of distal anastomosis between cardioplegia groups. If there is a significant difference between groups, this answer can change the aortic cross clamp times regardless of cardioplegia.We congratulate Algarni et al. for their valuable manuscript about cardioplegia solutions in coronary artery bypass surgery. We would like to hear authors’ opinion on this matter.References:1. Algarni KD. Routine use of del Nido cardioplegia compared with blood cardioplegia in all types of adult cardiac surgery procedures.
