Background and Objectives: lntraaortic Balloon Pump (IABP) is a device for improving circulation of heart. IABP uses the principle of diastolic counlerpulsation which augments diastolic coronary perfusion pressure, reduce systolic aftcrload, favorably affects the myocardial oxygen supply-demand ratio, and augments cardiac output. The aim of this study is evaluating application of IABP and complication of this method in Shahid Madani Heart Hospital.
Materials and Methods: This retrospective study was performed in Shahid Madani Heart Hospital from 1998-20(X) in 1134 patients, underwent coronary bypass surgery. In Forthy-three patients in this period. IABP had been used during surgery. Collecting data has been performed through filling ayuestionnaire consisting of age, sex, results of angiography, MI history and IABP complications and mortality rate. The statistical analysis is based on the SPSS software and has been done through descriptive statistical method.
Results: In this study, 72% of patients were male and 28% were female. Mean age of patients in both groups was 57.4±7.8 years old. 46,5% of patients were in emergency condition at the lime of surgery. 76.74% of patients, had a history of pervious myocardial infarction. En 67.5% of patients IABP was implanted in Operating Room (OR) due to difficult weaning from Cardiopulmonary Bypass (CPB) or immediately after Coronary Artery Bypass Graft (CABG) due to hemodynamic instability, and only in 32.5% patients it was implanted in a prophylactic manner before surgery. Overall in-hospital mortality rate was 32.5%. Persistent limb ischemia despite balloon removal, was reported in 4.65% of patients. Controllable local bleeding was reported in 11.6% of patients.
Conclusion: The results of this study, show that complication rate associated with IABP implantation in Shahid Madani Hospital, is comparable with those of other reports. IABP implantation in our hospital was usuallly preserved for very high risk patients with hemodynamic impairment. It is important to note that in the past, patients had been deprived form potential benefits of IABP, possibly due to restricted facility, in Shahid Madani Hospital.
