Balloon aortic valvuloplasty (BAV) is a treatment for high risk patients with severe aortic valve stenosis (AS). Rapid pacing is needed to reduce cardiac output when dilating the balloon, but it may cause cardiac ischemia or lethal arrhythmia. In this case report, percutaneous cardiopulmonary support (PCPS) was used to prevent these complications with BAV. We achieved adequate blood pressure and cardiac output during BAV without using rapid pacing by drawing a certain amount of blood into the reservoir equipped with the PCPS circuit. When performing BAV, PCPS may be a useful option for the patients who have high risks of circulatory failure.

BACKGROUND: Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. METHODS: A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. RESULTS: The patients' BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1+/-3.74 kg/m2). Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041). A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus) and coagulase-negative Staphylococci (P=0.011). There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048). The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. CONCLUSIONS: Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.
