Evaluation of prosthetic valve function is a challenging task. The clinician has to employ multiple parameters to quantify dysfunction (if present), the results of which can be mutually discrepant. This results from heterogeneity in the design of the valves themselves, implantation techniques, and both intra- and interpatient hemodynamic variability. Specifically, the location and angle of valve implantation can have a profound impact on its flow characteristics that can lead to symptoms despite satisfactory mechanical function. The authors present the case of inverted implantation of a prosthesis designed for the aortic position in the mitral annulus and resultant mitral stenosis. What follows is an examination of how the flow characteristics, such as pressure recovery, energy loss, and vortex formation, create a gradient that could not be explained by valve size alone., (Copyright © 2019.

Objective: Postoperative respiratory failure requiring reintubation is associated with a significant increase in mortality. However, perioperative risk factors and their effects on unplanned 30-day reintubation and postoperative outcomes after unplanned reintubation following lung resection are not described well. The aim of this study was to determine whether certain comorbidities, demographic factors, and postoperative outcomes are associated with 30-day reintubation after thoracic surgery., Design: This was a retrospective observational study using multivariable logistic regression to identify preoperative risk factors and consequences of unplanned 30-day reintubation., Setting: Multi-institutional, prospective, surgical outcome-oriented database study., Participants: Using the American College of Surgeons National Surgical Quality Improvement Program database, video-assisted thorascopic surgery and thoracotomy lung resections (lobectomy, wedge resection, segmentectomy, bilobectomy, pneumonectomy) were analyzed by Common Procedural Terminology codes from the years 2007 to 2016 in 16,696 patients undergoing thoracic surgery., Intervention: None., Measurement and Main Results: The final analysis included 16,696 patients, of who 593 (3.5%) underwent unplanned reintubation. Among the final study population, 137 (23%) of unplanned intubations occurred within 24 hours postoperatively and the median (25%, 75% quartile) day of reintubation was day 3 (2, 8 days). The final multivariable logistic regression analysis suggested that age, American Society of Anesthesiologists physical status classification score ≥4, dyspnea with moderate exertion and at rest, history of chronic obstructive pulmonary disease, male sex, smoking, functional dependence, steroid use, open thoracotomies, increased operation time, and preoperative laboratory results (albumin and hematocrit) were associated with unplanned intubation after lung resection (p < 0.05). Unplanned intubation was associated significantly with 30-day mortality, reoperation, postoperative blood transfusion, and increased hospital length of stay (p < 0.05)., Conclusions: Nonmodifiable and modifiable preoperative risk factors were associated with increased odds of unplanned reintubation. Patients who experienced unplanned intubation were at considerable risk for 30-day mortality, reoperation, postoperative blood transfusion, and increased hospital length of stay., (Copyright © 2018 Elsevier Inc.

Objectives: The hemodynamic consequences of ventilation of intubated patients during transport either by hand or using a transport ventilator have not been reported in patients after cardiac surgery. The authors hypothesized that bag-mask ventilation would alter end-tidal CO 2 during transport and hemodynamic parameters in patients post-cardiac surgery., Design: A prospective, randomized trial., Setting: A university-affiliated tertiary care hospital., Participants: Cardiac surgery patients., Interventions: Thirty-six patients were randomized to hand ventilation or machine ventilation. Hemodynamic variables including blood pressure, heart rate, peripheral saturation of oxygen, and end-tidal carbon dioxide (ETCO 2 ) were measured in these patients prior to transport, every 2 minutes during transport and upon arrival in the intensive care unit (ICU). Pulmonary artery pressure (PA) pressures were measured at origin and at destination., Measurements and Main Results: Outcomes were changes from baseline in end-tidal CO 2 , hemodynamic changes from baseline and pulmonary artery pressure changes from origin to destination. The average transport time between the 2 groups was not different: 5 minutes for patients ventilated by hand and 5.47 minutes for patients ventilated with a transport ventilator (p = 0.369 by 2-sided t-test). The difference in all measured changes in ETCO 2 between hand-ventilated and machine-ventilated patients during transport was 2.74 mmHg (p = 0.013). The difference between operating room and ICU ETCO 2 from each cohort was 1.31 mmHg (p = 0.067). The difference in PA mean measured at origin and destination was 0.783 mmHg (p = 0.622). All other hemodynamic variables were not different during transport., Conclusions: Hand ventilation during transport was associated with greater change from baseline of ETCO 2 compared to machine ventilation during transport after cardiac surgery, but this did not translate into any difference in hemodynamic changes upon arrival in ICU. A hemodynamic benefit of machine transport ventilation to cardiac patients was not demonstrated., (Copyright © 2017 Elsevier Inc. All rights reserved.)
