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.

Remifentanil Compared With Sufentanil Does Not Enhance Fast-Track Possibilities in Cardiac Surgery-A Randomized Study.
Progressive cost containment has resulted in a growing interest for fast-track cardiac surgery. Ventilation time and length of stay (LOS) in the intensive care unit (ICU) are important factors in patient turnover, a more efficient use of resources, and early patient mobilization. However, LOS in ICU is not an objective measure because, in addition to medical factors, patient discharge may be guided by logistics and policy, and thus more objective measures are warranted. The authors hypothesized that remifentanil compared with sufentanil would reduce ventilation time and LOS in the ICU and that remifentanil would have beneficial effects on the overall quality of recovery. ⋯ In a fast-track protocol, remifentanil did not seem to be superior to a standard moderate- to high-dose sufentanil regimen.

Left Ventricular Outflow Tract Area Measurements by Planimetry Using Two-Dimensional Simultaneous Orthogonal Plane Imaging During Transesophageal Echocardiography.
Calculations of the left ventricular outflow tract (LVOT) area are typically based on the assumption that the LVOT is circular. This study was conducted to determine whether simultaneous orthogonal plane imaging with tilt during two-dimensional (2D) transesophageal echocardiography provided more accurate measurements of the LVOT area than the standard method. ⋯ This study suggested that 2D planimetry may be more accurate than 2D diameter-based calculations.
