Propensity matching analysis was undertaken to compare the outcomes of such patients with those who underwent their surgery by the same surgeon using standard whole blood cardioplegia (WB group), n = 396. Propensity score matching yielded 79 pairs of patients.</p> </sec> <sec id="jocs12597-sec-0004" sec-type="section"> <title>Results</title> <p>After propensity matching, LC and WB groups were similar in baseline operative characteristics including cross‐clamp time (LC: 65 minutes [range 54 to 89] vs. WB: 70 minutes [54 to 86], p = 0.993). Postoperative outcomes were similar including inotropic requirements (30.4% [24/72] vs. 25.3% [20/72], p < 0.60), median ventilation time (4.7 hours vs. 5.3, p < 0.74) and median length of stay was seven days for both groups (p < 0.82). Despite higher median postoperative, 24‐hour CK‐MB levels LC group (LC:22.3 ng/ml, range [15.6 to 40.3] vs. WB:18.4 ng/ml [13.9 to 28.2], p = 0.040), operative and one‐year mortality were comparable among study groups (both p > 0.798).</p> </sec> <sec id="jocs12597-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Lidocaine containing cardioplegia appears to be safe in adults undergoing cardiac procedure when administered for the first 60 minutes of aortic cross clamping. Higher CK‐MB levels did not translate into adverse clinical outcomes. doi: 10.1111/jocs.12597 <italic>(J Card Surg 2015;30:677–684)</italic></p> </sec> </abstract>
