Transcatheter aortic valve replacement is a less invasive alternative for high-risk patients. However, valve embolization is a rare but dreaded complication. We report the successful off-pump retrieval of an embolized valve after transfemoral transcatheter aortic valve replacement through a left anterior thoracotomy. We maintained the embolized valve on the guidewire and snared it using a transapical approach. We then deployed a valve in an adequate position to ensure hemodynamic stability before transapical removal of the embolized valve...

REVIEW
Yoshio Misawa
BACKGROUND: Clinical results of ischemic left ventricular free-wall rupture show high mortality rates. METHODS: We reviewed studies published after 1993 on PubMed. RESULTS: A sutureless technique using fibrin glue sheets or patches with/without fibrin glue might contribute to improved clinical results. However, some technique limitations remain for blowout-type ruptures, and the possibility of a pseudoaneurysm formation at the repair site after surgery should be considered...

PURPOSE: Pre and post-operative administration of sevoflurane in myocardial revascularization surgery provides enhanced cardioprotective effects exerted by pharmacologic pre- and post-conditioning, as compared to propofol. The identification of the enzymes involved in conditioning mechanisms is crucial to the understanding of the effects of sevoflurane in cardiac surgery patients. The impact of sevoflurane on another crucial target organ-the kidney-was also assessed. METHODS: Ninety patients undergoing off-pump myocardial revascularization surgery were allocated to receive either intra- and postoperative sevoflurane (SS), intraoperative sevoflurane and postoperative propofol (SP), or intra- and postoperative propofol (PP))...

Tatsuya Seki, Toshihito Yoshida
BACKGROUND: Multiple studies have compared on-pump coronary artery bypass (ONCAB) grafting with off-pump coronary artery bypass (OPCAB) grafting, but the optimal surgical strategy has yet to be established. Furthermore, there is limited evidence regarding mid-term graft patency rates. METHODS: Between April 2001 and March 2014, 365 consecutive patients underwent isolated coronary artery bypass grafting (CABG; male: 75%; mean age: 69 ± 10 years). After propensity-score-matched analysis, we assessed the results of 67 patients in each group (ONCAB: group A, OPCAB: group B)...

INTRODUCTION: A number of large-scale retrospective studies revealed that off-pump coronary artery bypass (OPCAB) was superior to on-pump coronary artery bypass (ONCAB). The aim of the study was to investigate risk factors for mortality when OPCAB is converted to ONCAB. METHODS: Patients who underwent OPCAB conversion to ONCAB at the Beijing Anzhen Hospital between January 2003 and January 2013 were assigned to the non-survivor and survivor groups. Background demographics, illness history and preoperative, intraoperative and postoperative variables were compared...
