Left Ventricular Systolic Dysfunction in Patients With Type-A Aortic Dissection Is Associated With 30-Day Mortality.
The aim of this study was to analyze preoperative and postoperative echocardiographic parameters in patients with type-A acute aortic dissection (ATAAD) and to analyze whether impaired preoperative left ventricular function was associated with short- and long-term survival. To enable multivariable analysis, established risk factors of ATAAD were analyzed as well. ⋯ After surgery, aortic insufficiency and pericardial effusion decreased, whereas cardiac functional parameters did not change. Severe LV dysfunction was identified as a new independent predictor of 30-day mortality.

Long-Term Outcomes After Extracorporeal Life Support for Acute Respiratory Failure.
This study aims to determine the prevalence of functional and psychological impairment in survivors of extracorporeal life support (ECLS) and assess the needs of survivors to guide development of an effective follow-up program. ⋯ This study demonstrated persistent physical and psychological impairments in survivors of ECLS. Patients consistently expressed a desire to debrief on their hospital course and receive education on possible long-term effects. Study findings suggest that structured follow-up may allow for early identification of psychological and physical impairments to improve outcomes. Future studies should focus on investigating the effect of rehabilitation and follow-up clinics in preventing these issues.

The Effect of Modified Ultrafiltration on Serum Vancomycin Levels During Cardiopulmonary Bypass in Cardiac Surgery.
The aim of this study was to investigate whether the use of modified ultrafiltration at the end of cardiopulmonary bypass for cardiac surgical procedures significantly changes vancomycin serum concentrations. ⋯ Using modified ultrafiltration at the end of cardiopulmonary bypass significantly decreases serum vancomycin levels, but not by a clinically relevant amount. The decrease is to a concentration that is still significantly higher than the minimum inhibitory concentration for Staphylococcus epidermidis and Staphylococcus aureus; thus additional vancomycin administration is not recommended.

Multicenter StudyPractice Pattern Variation in the Use of Transesophageal Echocardiography for Open Valve Cardiac Surgery.
The authors sought to assess for the presence of practice variation in the use of intraoperative transesophageal echocardiography (TEE) for open cardiac valve surgery. ⋯ Among adult patients undergoing open AV or MV surgery in the United States, 82% had a claim for an intraoperative TEE with marked variability across U.S. states. Increasing adherence to intraoperative TEE guidelines for valve surgery may represent an unrecognized opportunity to improve the quality of cardiac surgical care.

Review Case ReportsLate Clinical Presentation of Prosthesis-Patient Mismatch Following Transcatheter Aortic Valve Replacement.
Prosthesis-patient mismatch (PPM) is relatively common after aortic valve replacement (AVR) and generally is associated with reduced regression of left ventricular (LV) mass. PPM after valve-in-valve transcatheter aortic valve replacement (TAVR) was reported to be 38%. PPM generally is manifested clinically by dyspnea and echocardiographically by high transvalvular gradients. In this E-Challenge, the authors will review a case of a late clinical presentation of PPM 1-year following a valve-in-valve TAVR.
