[Myocardial revascularization for sudden cardiac death in patients after previous coronary angioplasty].

UNLABELLED: PTCA was introduced into our hospital in June 1991. Since then till the end of 1996 emergency CABG operations were performed in fourteen patients. They were indicated because of acute myocardial ischaemia and hemodynamic deterioration that was the result of the dissection and occlusion of a coronary artery during angioplasty. There were 11 male and 3 female patients in this group aged 34 to 65 average 50 years. Twenty-three grafts were performed in total (18 saphenous, 5 using internal mammary artery), that is 1.6 graft per patient. A female patient died of myocardial infarction on the first postoperative day. All other patients survived and are under outpatient clinic's care. Over the analysed 6 years' period of time 1079 PTCAs were performed. The low rate of the unsuccessful procedures (1.3%) that required the emergency CABG is noteworthy. Since 1995, when the implantation of stents was introduced into our hospital, there were only 2 such procedures (0.4% of all PTCAs).

CONCLUSIONS: The CABG operation performed shortly after a dissection and occlusion of the coronary artery underwent angioplasty usually prevents myocardial infarction and saves the patient's live. The introduction of implantation of the stents significantly diminished a number of patients who required an emergency CABG operation.
