Intervention Details:

performed in adjunct to a standard coronary artery bypass grafting procedure Prior to aortic cross clamping direct epicardial shock wave therapy - applied directly to the myocardium

Detailed Description:

Direct epicardial shock wave therapy: DESWT will be performed in adjunct to a standard CABG procedure. Prior to aortic cross clamping, DESWT will be performed using a CardioGold® CG050 (CRT Cardiac Regeneration Technologies, Woodstock, USA / manufactured by MTS-Europe GmbH, Konstanz, Germany) shock wave therapy device and a specially designed handheld applicator under sterile conditions. Depending on the localisation of the myocardial infarct scar, 290-310 impulses will be applied to the anterior, lateral, or posterior wall. Shock waves will be generated at 1 or 2 Hz in a non ECG triggered fashion, should DESWT result in significant ventricular arrhythmias, ECG gating will be initiated. After completion of DESWT, CABG will be continued in a regular fashion.
