Including a control group with no optimization and with baseline device settings may answer this question: “Is routine optimization necessary for all CRT-D patients” and may show us the specific role of optimization just for nonresponder patients. In addition, it would have been beneficial for the study to report pacing percentages during device follow-up in patients who showed clinical improvement, and to discuss the presence or absence of leads in scarred myocardial regions. Despite these limitations, conducting such a complex and labor-intensive study involving both invasive and echocardiographic optimization in a single center with 40 patients is highly fascinating and commendable.}, number={3}, publisher={Eskişehir Şehir Hastanesi}
