The Outcomes of Intraaortic Balloon Pumping for Patients with Valvular Heart Surgery / 日本心臓血管外科学会雑誌

ABSTRACT

Clinical evaluation of perioperative IABP use in valvular heart surgery was studied. There were 4 preoperative, 18 intraoperative and 20 postoperative applications of IABP. The indications of IABP were LOS in 19 patients, failed weaning from bypass in 11, life threatening arrhythmia in 11, and congestive heart failure in 1. Sixteen out of 26 patients with successful weaning from IABP support could be discharged. Ten died after removal of IABP. Longer duration of cardiopulmonary bypass and aortic clamp, lower value of cardiac index 24 hours after introduction of IABP support were implicated in unsuccessful IABP support. The causes of death were due to LOS in 8 patients, MOF in 12, GVHD in 2, others in 3. The outcome of IABP for patients with valvular heart surgery was not satisfactory. However, the results of IABP support in valvular surgery will be improved by reducing the incidence of postoperative complications, especially LOS, followed by MOF.
