We retrospectively evaluated the initial clinical experience of intraoperative cardiac output measurement by a new arterial pressure-based cardiac output (APCO:FloTrac/Vigileo) analysis in patients undergoing open heart surgery. Thirty-two patients (mean age 76.4, range 59 to 90)who underwent cardiac surgery under cardiopulmonary bypass( CPB) from July 2008 to September 2009 in our institute were enrolled in this study. There were 14 women and 18 men. ⋯ Before the institution of CPB, 3 of the 6 at T1 and 3 of the 7 at T2 in whom no correlation was shown, had severe aortic valve insufficiency (AVI). From these results, APCO appears to be an acceptable device to evaluate the intraoperative cardiac output measurement compared with CCO, except in patients with LV dysfunction or AVI at some time points. Further studies will be necessary to elucidate the precise clinical evidence to assess the efficacy of this new analysis device.

An 86-year-old female patient was transported to our hospital because of progressive dyspnea. Computed tomography revealed a 7-cm-diameter low-density mass located in the upper mediastinum behind the trachea. The mass compressed the trachea and caused severe tracheal stenosis. ⋯ The postoperative course was uneventful, and the patient was discharged from the hospital on the 14th postoperative day. The tumor was histologically diagnosed as a bronchogenic cyst. Six months after the operation, she was still asymptomatic.
