Inclusion Criteria

The study population will be selected from patients of either sex who are to undergo for aortic valve surgery (with and without coronary bypass surgery).

(1) Patients >/=30 and (2) Male or female with aortic valve disease
(3) Able to understand character and individual consequences of the clinical trial and to provide written informed consent to participate in the study
(4) Women of childbearing potential (ie, those who have not undergone a hysterectomy or who have not been post-menopausal for at least 12 consecutive months) must test negative for pregnancy prior to bypass surgery.
Are the trial subjects under 18? no
Number of subjects for this age range:

Exclusion Criteria

(2) Left ventricular ejection fraction < 25% (as assessed by any one of the following: contrast ventriculography, multigated acquisition scanning [MUGA], or 2-D ECHO)
(3) Patients on intra-aortic balloon devices or with history of previous coronary artery bypass surgery
(4) Pregnant or lactating patients
(5) Patients who have participated in any other investigational studies within 30 days previous to enrollment
(6) Patients in cardiogenic shock (defined as a systolic BP < 90 mmHg for over one hour despite inotropic and chronotropic support)
(7) Patients with severe chronic obstructive lung disease (FEV1 < 50%)
(8) Previous cardiac valvular disease (clinical relevant)

Primary Outcome Measures
NameTimeMethod
Main Objective: The objective of this investigation is to compare the cardioprotective effects and safety of two cardioplegic solutions, Custodiol and Custodiol-N in patients undergoing aortic valve surgery +/- bypass surgery.;Secondary Objective: to demonstrate superiority in surgical outcome of Custodiol-N compared with Custodiol as determined by CK-MB peak value between 4 - 24 hours after opening of the aortic cross-clamp (primary endpoint), catecholamine requirement (cumulative dose) and cardiac Troponin T, occurrence of comorbid events postoperatively (e.g., myocardial infarction);Primary end point(s): CK-MB peak value ;Timepoint(s) of evaluation of this end point: from 4 to 24 hours (measurements 4, 8, 12, 16, 20, 24 hours ± 30 min) after release of the aortic cross clamp
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): • Catecholamine requirement on SICU within 24 hours (cumulative dose)<br>• CK-MB (peak) on the days 2, 3, 4 and 5 after removal of aortic cross clamp<br>• Cardiac Troponin T 4, 8, 12, 16, 20, 24 hours ± 30 min and on the days 2, 3, 4 and 5 after release of the aortic cross clamp<br>• CK-MB area under the curve between 4 and 24 hours after removal of the aortic cross-clamp<br>• Troponin T area under the curve between 4 and 24 hours after removal of the aortic cross-clamp<br>• Defibrillation<br>• Requirement for IABP<br>• Blood pressure<br>• Length of SICU stay<br>• Duration of mechanical ventilation (intubation to extubation)<br>• Occurrence, severity, type, and duration of cardiac arrhythmias <br>• Laboratory parameters<br>• Repeated patient transfer to SICU<br>• Mortality any time during post-op through Day 30<br>• Safety (documentation and reporting of AE and SAE)<br>;Timepoint(s) of evaluation of this end point: see above (Point E.5.2)
