Observational StudyThe Accuracy of Velocity-Time Integral Variation and Peak Velocity Variation of the Left Ventricular Outflow Tract in Predicting Fluid Responsiveness in Postoperative Patients Mechanically Ventilated at Low Tidal Volumes.
To assess whether velocity-time integral (VTI) variation and peak velocity (Vpeak) variation of the left ventricular outflow tract (LVOT) accurately could predict fluid responsiveness in postoperative critically ill patients mechanically ventilated at low tidal volumes. ⋯ In postoperative critically ill patients mechanically ventilated with tidal volume <8 mL/kg, the VTI variation and Vpeak variation of LVOT accurately could predict fluid responsiveness, and VTI variation showed more accuracy than Vpeak variation in predicting fluid responsiveness.

Perioperative Outcomes During Double-Lung Transplantation and Retransplantation in Cystic Fibrosis Patients: A Monocentric Cohort Study.
Life expectancy for lung-transplant patients, especially those with cystic fibrosis (CF), is leading increasingly to more retransplantations. ⋯ Intraoperative period of retransplantation was more convoluted but had a similar ECMO profile to primary transplantation. In addition, the early postoperative period was similar.

An Assessment of the Practice of Neuromuscular Blockade and the Association Between Its Prophylactic Use and Outcomes Among Postoperative Pediatric Cardiac Patients.
The authors investigated the management of neuromuscular blocking agents (NMBAs) for pediatric patients after cardiac surgery, and compared the outcomes of patients who received prophylactic NMBA (pNMBA) infusions and patients without pNMBA infusions. ⋯ Postoperative prophylactic neuromuscular blockade after cardiac surgery can be associated with prolonged mechanical ventilation, but has no association with MAEs among pediatric patients with congenital heart disease.

Observational StudyThe Long-Term Impact of Diastolic Dysfunction After Routine Cardiac Surgery.
To determine the impact of diastolic dysfunction (DD) on survival after routine cardiac surgery. ⋯ These findings suggested that DD may be associated with poor short-term and long-term outcomes.

The Use of Contrast May Improve Aortic Valve Assessment During Transesophageal Echocardiography.
The Doppler profile that quantifies the degree of aortic stenosis is essential, as an inaccurate measurement can alter the surgical plan. The authors aimed to examine the level of agreement between the contrast and noncontrast methods of aortic valve sizing during intraoperative transesophageal echocardiography (TEE). ⋯ This discrepancy is significant and could affect the decision to replace the aortic valve. When evaluating the aortic valve with TEE, the authors recommend using a contrast agent to improve the Doppler profile and to obtain a more accurate measurement of the aortic valve area.
