Comparative StudyComparison of Two Different Red Blood Cell Transfusion Thresholds on Short-Term Clinical Outcomes of Patients Undergoing Aortic Surgery with Deep Hypothermic Circulatory Arrest.
Patients undergoing aortic surgery with deep hypothermic circulatory arrest (DHCA) usually are associated with a high rate of allogeneic blood transfusion, and their red blood cell (RBC) transfusion threshold is unclear and controversial. The purpose of this study was to explore whether a restrictive transfusion threshold was as effective as a liberal transfusion threshold for patients undergoing aortic surgery with DHCA. ⋯ For patients undergoing aortic surgery with DHCA, a restrictive RBC transfusion threshold (Hb<8 g per deciliter) may be as effective as a liberal RBC transfusion threshold (Hb<10 g per deciliter) during the surgery, with similar short-term clinical outcomes and less allogeneic transfusion.

Comparative StudyMonitored Anesthesia Care Versus General Anesthesia: Experience with the Medtronic CoreValve.
To compare monitored anesthesia care (MAC) and general anesthesia (GA) for transcatheter aortic valve implantation (TAVI). ⋯ GA provides no significant advantages over MAC during TAVI.

Observational StudyNoninvasively Measured Hemoglobin Concentration Reflects Arterial Hemoglobin Concentration Before but Not After Cardiopulmonary Bypass in Patients Undergoing Coronary Artery or Valve Surgery.
This study compared noninvasively measured hemoglobin and arterial hemoglobin before and after cardiopulmonary bypass in patients undergoing coronary artery or valve surgery. ⋯ The results suggested that noninvasive measurement of hemoglobin overestimates arterial hemoglobin by almost 1 g/dL when compared to iSTAT. A lack of precision also was observed with noninvasive measurement of hemoglobin, especially after cardiopulmonary bypass. These findings supported the contention that sole reliance on noninvasive measurement of hemoglobin for transfusion decisions in cardiac surgery patients may be inappropriate.

Observational StudyFunction of the Respiratory System in Elderly Patients after Aortic Valve Replacement.
To compare the function of the respiratory system after aortic valve replacement through median sternotomy (AVR) or the minimally invasive right anterior minithoracotomy (RAT-AVR) approach among elderly (aged≥75 years) patients. ⋯ RAT-AVR surgery resulted in shorter postoperative mechanical ventilation time and improved the recovery of pulmonary function in elderly patients, but it did not reduce the incidence of pulmonary complications when compared with surgery performed through a median sternotomy.
