[Clinical evaluation of intraoperative cardiac output measurement by a new arterial pressure waveform analysis method( FloTrac/Vigileo) in open heart surgery].

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.

[Open heart surgery in a patient with a history of Takotsubo cardiomyopathy].

An 81-year-old man had a history of Takotsubo cardiomyopathy induced by general fatigue after travel and acute gastritis 2 years previously. Recently, dyspnea on effort had been worsening. Since preoperative echocardiography showed severe aortic valve regurgitation (AR) with left ventricular (LV) dilatation, aortic valve replacement (AVR) by the standard procedure was indicated.
