The purpose of the study is to demonstrate that Custodiol-HTK is not inferior to cold cardioplegic solution in patients undergoing cardiovascular surgery requiring cardioplegic arrest.
The objective of this study is to demonstrate that Custodiol is not inferior to cold cardioplegic solution for myocardial protection by comparing standard cold blood cardioplegia to Custodiol solution with respect to myocardial injury as measured by Creatine phosphokinase MB isoenzyme (CK-MB),troponin-I at 7 hours post surgery and changes in ejection fraction by trans-thoracic echocardiogram (TTE)or trans-esophageal echocardiogram (TEE) at 24 hours post surgery.

After cross-clamping of the aorta approximately 1-2 L of Custodiol-HTK was infused into the ascending aorta over 6-8 minutes. Additional doses of 100-200 ml were administered as needed. The cardioplegic solution was delivered at a temperature of 4°C - 10°C.
After cross-clamping the aorta, at least 1000 mL of a 4:1 mixture of cold blood: cold crystalloid was administered at a pressure of 300 mmHg or less via a twin roller pump. Every 20 minutes an additional \> 200 mL was administered in an antegrade/retrograde fashion throughout the remainder of the case. The cardioplegic solution was delivered at a temperature of 4°C - 8°C.
