Between May, 1994 and December, 1995, 122 adult cardiac surgical procedures requiring cardiopulmonary bypa s were performed at Kang Dong Sacred Heart Hospital, including 18 cases(14.8%) that were associated with preoperative(n:9), intraoperative(n=7), postoperative(n:2) use of an IABP (intra-aortic balloon pump). The reasons for IABP were low cardiac output and PTCA(percutaneous transluminal coronary angioplasty) failure in preoperative period, CPB(cardiopulmonary bypass) weaning difficulty in intraoperative period, and intractable arrhythmia in postoperative period. The mean age of the IABP patients was 61.8 $\pm$ 6.9 years(range, 39 to 75years). The overall hospital mortalities in patients with preoperative and intraoperative IABP insertion were 3 and 42.9% respectively. Two patients with postoperative IABP insertion are alive. The rate of IABP weaning is 66.7% for preoperative group, 85.7% for intraoperative group and 100% for postoperative group . In conclusion, if there were no irreversible myocardial damages, IABP could be used safely and emergently at any perioperative period for hemo ynamic stability, CPB weaning, and to overcome low cardiac output syndrome.

Intra-aortic balloon pump (IABP) is well known for its hemodynamic benefit but still has its own complications. Proper use of IABP is the best way to obtain maximum benefit with low complication rate. Material and Method： Twenty one(men 10, female 11) patients were included in this study among the 100 consecutive adult cardiac surgery patients in our hospital. Eighteen(85.7%) were ischemic heart disease patients. They all received IABP therapy due to postcardiotomy cardiogenic shock according to the well-known indications. Their preoperative conditions, intraoperative factors including hemodynamics, postoperative conditions and IABP-related complications were analyzed. Result： Nineteen patients(90.5%) were successfully weaned from IABP. There were 2 patients of operative death and the mortality rate was 9.5%. Duration of IABP use was 40.7$\pm$24.3 hours. There were 2 cases(9.5 %) of IABP-related vascular complications that required surgical intervention. Conclusion： We concluded that IABP could be used effectively and safely for postcardiotomy cardiogenic shock patients with low complication rate.

From December 1981 to June 1987, thirty one patients suffering from low output syndrome after cardiac operation received cardiac assist with intraaortic balloon pump. Fifteen patients survived [survival rate 48.4%]. After receiving assist with IABP, urine output increased, heart rate and central venous pressure decreased, reflecting improved myocardial performance. Poor preoperative hemodynamic and functional status resulted in poor survival despite of assist with IABP. Poor pre-IABP hemodynamic status also resulted in high mortality after assist with IABP. Our experience suggests that IABP should be introduced early in the course of worsening to get good result.

From July 1986 to June 1987, five patients were underwent IABP [intra aortic balloon pulsation] because of sever left heart failure in spite of maximum medication. These patients were reviewed as prophylactic IABP [1 patient], During operation [3 patients] and postoperative IABP [1 patients]. All patients were showed stable hemodynamic status with improved LV function during and after IABP. there was no IABP related complication or mortality. Advanced disease needs more effective methods of mechanical circulatory assistance and heart replacement.

Intra-aortic balloon pump [IABP] was applied to 12 patients between July, 1987, and September, 1990. The 12 patients included 8 who were assisted with IABP intraoperatively; 4 patients used IABP postoperatively. 8 patients could not be withdrawn from cardiopulmonary bypass [CPB], but 6 of them [75%] were able to separate from CPB with IABP. They all were withdrawn from the balloon. Four [50%] of them are hospital survivors, and alive at the time of this report. 4 additional patients were assisted with IABP, postoperatively. 2 of them [50Yo] were withdrawn from the balloon but died. The overall survival and balloon weaning rates are 33.3% [4/12] % 66.7% [8/12], respectively. IABP was most effective when applied early to patients who had transient and reversible injury to the myocardium.

Background: We sought to examine the use and outcomes of early intraaortic balloon counterpulsation(IABP) combined with early reperfusion therapy in patients presenting cardiogenic shock complicated acute myocardial infarction. The usc of IABP in patients with cardiogenic shock is widely accepted. However there is not ample information on the use of this technique in patients with cardiogenic shock who arc treated with reperfusion therapy in Korea. Materials and Methods: Twenty-eight patients presented with cardiogenic shock were classified into two groups: the early IABP group (insertion within 12 hours after AMI onset time) and the late IABP group (insertion after 12 hours). We compared In-hospital mortality between the two groups (early IABP group vs late IABP group). Results: Two groups showed no significant difference in clinical feature and coronary angiographic results. Among total 28 patients, 7 patients were treated with thrombolytic therapy and 21 patients with PTCA. Insertion site bleeding, fever, thrombocytopenia were reported as some of the complications of IABP insertion. In-hospital mortalities in the early IABP group and late IABP group were 4 patients(25%) and 8 patients(66%), respectively(p<0.05). Early IABP insertion and early PTCA showed lower hospital mortality rates. There was significant difference in the time to PTCA after AMI onset between the two groups(p<0.05). Conclusion: IABP appears to be useful in patients presenting cardiogenic shock unresponsive medical therapy. Early IABP insertion and early reperfusion therapy may reduce in-hospital mortality rates of post-MI cardiogenic shock patients.

Background: We aimed to investigate the preoperative, operative, and postoperative factors affecting intra-aortic balloon pump (IABP) insertion in patients undergoing isolated on-pump coronary artery bypass grafting (CABG). We also investigated factors affecting morbidity, mortality, and survival in patients with IABP support. Methods: Between January 2002 and December 2009, 1,657 patients underwent isolated CABG in Izmir Katip Celebi University Ataturk Training and Research Hospital. The number of patients requiring support with IABP was 134 (8.1%). Results: In a multivariate logistic regression analysis, prolonged cardiopulmonary bypass time and prolonged operation time were independent predictive factors of IABP insertion. The postoperative mortality rate was 35.8% and 1% in patients with and without IABP support, respectively (p=0.000). Postoperative renal insufficiency, prolonged ventilatory support, and postoperative atrial fibrillation were independent predictive factors of postoperative mortality in patients with IABP support. The mean follow-up time was $38.55{\pm}22.70$ months and $48.78{\pm}25.20$ months in patients with and without IABP support, respectively. The follow-up mortality rate was 3% (n=4) and 5.3% (n=78) in patients with and without IABP support, respectively. Conclusion: The patients with IABP support had a higher postoperative mortality rate and a longer length of intensive care unit and hospital stay. The mid-term survival was good for patients surviving the early postoperative period.

In a 53-year old male with post-infarction ventricular septal defect [VSD , owing to an acute exacerbation of pulmonary edema, respiratory failure developed, and the ventilatory support and intraaortic balloon counterpulsation [IABP were applied. At the following day, operation was performed with the aid of IABP. Under the cardioplumonary bypass, he underwent infarctectomy, trimming of VSD margin, patch closure of VSD and infarctectomy site. Left ventricular free wall rupture was detected during operation, which was confined with pericardial adhesion. Post-operative course was uneventful, and he could be discharged with minimal degree of dyspnea [NYHA class II .
