Characteristic of patients surviving over a long-term period after intra-aortic balloon counterpulsation treatment.

Control examination of 21 patients after cardiac surgery which required the application of intra-aortic balloon counterpulsation in order to terminate extracorporeal circulation showed that, in spite of the serious postoperative course, the prognosis and quality of their life is a good one. Objective signs of left ventricular function show rather a moderate deterioration. Patients after myocardial revascularization have at the same time a demonstrable ischaemic disease of the lower extremities. Changes of more serious nature on the arteries of the lower extremities in connection with the earlier application of intra-aortic balloon counterpulsation could not be documented.

Intraaortic balloon counterpulsation.

The authors summarize their experience with intraaortic balloon counterpulsation (IABC) at the Institute for Clinical and Experimental Medicine between 1978-1984. A total of 756 cardiac surgery procedures were performed for ischaemic heart disease (IHD), and 266 procedures for rheumatic heart disease (RHD). Of patients operated on for IDH, IABC was used in 38 (5%) and, of those undergoing surgery for RHD, in 38 cases (14%). Overall, IABC was employed in 76 patients, i.e., 7%. Ventricular assistance using IABC was successful in 55% of patients. The technique was significantly more successful in IHD (68%) than in RHD (42%) patients. IABC was less successful in IHD patients suffering myocardial infarction intraoperatively. Moreover, the success of IABC depended on its early initiation. Eleven patients (14%) developed complications associated with IABC. The data do not differ from results reported by world's leading centres.

Haemodynamic changes immediately following myocardial revascularization.

The haemodynamic values before and immediately after direct myocardial revascularization were compared in 14 patients with ischaemic heart disease. Within the first hours after surgery cardiac output decreased to 50% of the preoperative value owing to a decrease in stroke volume, wedge pressure was increased, and systemic pressure was maintained at preoperative values by a rise in peripheral resistance. After the initial decrease cardiac output again increased to preoperative values (after 7 h) and above these values (19 h after surgery). Systemic blood pressure decreased owing to rapidly decreasing peripheral resistance. Knowledge of the pattern of haemodynamics in the early postoperative period facilitates the diagnosis of untoward circulatory episodes and permits to distinguish the effect of therapy from the haemodynamic changes normally occurring during this period.
