During last eight years, retrograde delivery of cardioplegia was used on a regular basis, utilizing a DLP INC (Grand Rapids, MI) or a Research Medical INC (Salt Lake City UT) delivery systems, in almost an equal number of patients. This method resulted in a high pressure rupture, or perforation of the coronary sinus, its radicals or the right ventricle (RV) in 0.06% (5/7886) of patients. Intraoperative diagnosis of these injuries were confirmed on abnormal haemodynamic tracings and trans oesophageal echocardiography (TOE), and appearance of cardiac contusion or leakage of cardioplegia. A low incidence of these iaterogenic injuries may be attributed to: (1) a regular use of this method and (2) use of TOE guided manipulations in select high risk and reoperative patients. Repair of these injuries, as described, resulted in salvage of 4/5 (80%) patients.
