Safety and Efficacy of Cardiac Shockwave Therapy in Patients Undergoing Coronary Artery Bypass Grafting

The cardiac shockwave system consists of a table-top device (Nonvasiv Medical GmbH, Konstanz, Germany) and a sterile single-use applicator releasing electrohydraulic shockwaves (Heart Regeneration Technologies GmbH, Innsbruck, Austria). Prior to use, the applicator is inserted into a sterile cover containing ultrasound gel. In order to ensure acoustic coupling between the applicator and the myocardium, continuous saline rinsing is applied throughout the procedure.
